(latest entries created by git log --no-merges --pretty="%ai %an <%ae>:%n%s%n%n%b" vlast.. )

2013-02-05 22:52:42 -0800 Arun Persaud <arun@nubati.net>:
new version number for release of 4.7.0


2013-02-05 11:56:10 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let initial setting of Twice checkbox reflect current state

The Twice checkbox in the Tournament dialog of WinBoard was by default
starting unticked. It is more convenient to have it preserve the current
state, however, based on the -lpi or -lgi value. Like the auto-incremet
checkbox already did.

2013-02-04 22:07:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put GTK warning in about-box


2013-02-04 21:59:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix warnings of build server


2013-02-02 15:58:04 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix GTK error auto-raising board

The variable mainwindow is not set in the gtk2 version. Unfortunately
it is still used to determine default board size...

2013-02-01 19:42:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Update Dutch WB translation


2013-02-01 19:37:06 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add some new strings to WB translation template


2013-02-01 19:34:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Assign shortcut char to WB menu item

The new Save games as Book item did not have a shortcut yet.

2013-02-01 19:31:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let WinBoard start in its installation folder

The current directory in WinBoard was not automatically the same as the
installDir returned by SearchPath. Especially not if used without shortcut
by file association.

2013-02-01 19:29:26 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix warning in WinBoard


2013-01-30 14:25:57 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix expose of to-square with grid off

The code relied on drawHighlight to request an expose evet for the entire
square, but when lineGap = 0, drawHighlight is a no-op.

2013-01-29 08:39:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix library order

On OS X dialog windows could not get focus if -lXaw appeared after
-lX11 -lXt in the linker command. This was cured by moving
@FRONTEND_FLAGS@ (which expands to -lXaw) first in the LDADD parameter
of the automake file.

2013-01-28 17:38:26 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Preserve PGN tags when loading engine

Switching to EditGame mode would normally erase the tags, but when analyzing
a loaded game this would be undesirable. When the engine is playing, keeping
the tags is dubious, but it is not obvious what to put in a new name tag,
so we leave that for now.

2013-01-28 17:23:47 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Preserve mode on engine loading (sometimes)

That the mode always switched to EditGame after engine loading was
particularly annoying at the start of a game (where leaving BeginningOfGame
mode would disablethe Time Control dialog, and the engine would not
automatically reply if you start playing) and AnalyzeMode. These two
modes are now preserved, BeginningOfGame by refraining from calling
EditGameEvent() and sending 'force' to the new engine, and AnalyzeMode
be calling AnalyzeModeEvent() after the engine is loaded and repositioned.

2013-01-28 14:14:19 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Catch unknown engine in tourney games

When an XBoard instance is playing on a tourney it can happen that it is
using a settings file with an engine list not yet containing a certain
participant, because that participant was just installed in the instance
that created the tourney file, but it did not save those modifications yet.
This error is now caught, and leads to an error popup and stopping of the
tourney play. This error was made non-fatal to allow the user to decide
if he wants to quit with or without saving the settings (which, after all,
does not seem up-to-date).

2013-01-26 18:08:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Adjudicate pawn-drop mate as loss in Shogi

Mating with a Pawn drop is illegal in Shogi, but rather than burdoning
the legality-testing by this complex rule, we simply invert the result
for such a mate. After all, Shogi customs are such that everything illegal
leads to an immediate loss.

2013-01-25 10:05:44 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Adjudicate perpetual checks as loss also in Shogi

The Xiangqi code for recognizing perpetual checks is now also activated for
Shogi, but in this case we bail out before checking for perpetual chases.
The mini-Shogi case is then recognized as a win for gote.

2013-01-25 09:55:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Stalemate is a win in Shogi

In regular Shogi this never occurs, but in the mini variants it happens
often enough.

2013-01-22 20:49:34 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix engine timeout problem in match mode

Reload of a reuse=0 engine would cause a done=1 event which would be
abort the feature timeout of the other engine in the first game.

2013-01-22 20:32:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Enforce -popupMoveErrors

One move error was using DisplayError(), in stead of DisplayMoveError(),
and thus did not obey the -popupMoveErrors option.

2013-01-21 15:30:29 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Update texi file


2013-01-21 10:26:20 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix some warnings


2013-01-20 19:09:05 -0800 Arun Persaud <arun@nubati.net>:
Updated German translation


2013-01-19 17:54:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do delayed board draw also with -stickyWindows false

Only CoDrag needs to be suppressed on a configure event with
-stickyWindows false, not the board redraw.

2013-01-18 11:11:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let tellothers command add comment to PGN in local mode


2012-12-30 15:19:57 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow use of ~ in pieceToChar for shadow pieces in any variant

The use of shadow-pieces for promoted Pawns was limited to Crazyhouse and
Bughouse. But this is not necessary, and in fact undesirable, as it made
it impossible to implement Crazyhouse960, which combines shadow promotions
with Fischer castling (only available in variant fischerandom)s, and thus
has to be played as 8x8+5_fischerandom, using the Crazyhouse -pieceToChaTable.

2012-12-30 15:06:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Resend engine-defined options after reuse=0 reload

When the engine process is re-spawned for a new game under -xreuse setting,
any alteration of engine settings brought about through the Engine Settings
dialogs would be lost, and revert to the engine's default. This is now fixed
by re-sending all options (known from the previous load of the same engine)
with the current settings immediately after "protover 2", and ignoring the
engine's option features. Rather than clearing the option list, and
redefining it from the option features.

2012-12-30 14:58:16 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement aborting of games on engine request.

A new game-end command is added. For bakward compatibility it is disguised
as an old one, namely "1/2-1/2 {Engine Abort Request}". These resultDetails
are recognized as special, and rather than ending the game in a draw (which
GUIs not implementing this), the game will be completely 'expunged' from
the match or tourney it is part of, leaving no trace in the saveGameFile.

2012-12-30 14:54:43 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Store some more tourney params in tourney file

The hash and threads settings, as well as ponder and book options are now
also saved in the tourney file, so that tournaments can be played in
parallel where these parameters differ, and no mess up can occur on
restarting a touney after doing something else.

2012-12-23 11:26:31 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do not automatically save aborted games in tourney PGN

When the game result is 'unfinished', we prompt for a filename rather
then using the specified saveGameFile if a tourney is in progress.

2013-01-19 08:35:52 -0800 Arun Persaud <arun@nubati.net>:
fix configure bug that showed up on OS X (couldn't find X11/Dialog.h)

X_CFLAGS (set by AC_PATH_XTRA) was not used in Makefile.am. It was used in tests for X11/Dialog.h, etc. so configure worked, but make didn't.

2013-01-18 22:26:13 -0800 Arun Persaud <arun@nubati.net>:
Updated Ukrainian translations


2013-01-09 07:57:43 -0800 Arun Persaud <arun@nubati.net>:
removed trailing whitespace


2013-01-09 07:49:20 -0800 Arun Persaud <arun@nubati.net>:
Updated copyright notice to 2013


2012-12-22 22:46:21 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do not move to forwadMostMove when unpausing AnalyzeMode


2012-12-22 22:44:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use Ctrl key in AnalyzeMode to exclude entered move


2012-12-22 20:40:26 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement insufficient mating material for Knightmate

KBK is draw with Royal Knight. With exo-pieces also KNK and KFK.

2012-12-22 20:25:51 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix rep-draw detection in drop games

In games like Crazyhouse every move is reversible, as captured pieces
can eventually change sides again, and be dropped back on the board.
So we have to search back a full 100 ply for repetitions, passing captures
and Pawn moves.

2012-12-11 22:33:07 -0800 Arun Persaud <arun@nubati.net>:
updated po/pot files


2012-12-11 22:18:05 -0800 Arun Persaud <arun@nubati.net>:
new version number for developer release


2012-12-10 14:48:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Prefer pause mode on pondering engine over 'easy'

If the thinking engine is stopped after its move because it does not
support pause, is is still better to use pause on the pondering engine
than to switch of its pondering with 'easy', as the latter might not
be instantaneous. Also switch off pondering in the thinking engine before
it gives the move, just in case it does not respond immediately to
easy / hard.

2012-12-10 13:40:47 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Update WinBoard translation template


2012-12-10 13:35:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix min-Shogi promotion zone

In integer arithmetic N*2/3 is not the same as N - N/3, with as a result
that the white promotion zone was 2 ranks deep on 5x5 boards. This only
happened in LegalityTest, but because this would classify all moves to
4th rank an non-promotions, they would be printed with a faulty
deferral (=) sign as promochar in SAN.

2012-12-10 13:32:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do not clear PGN tags on Analyze File


2012-12-10 13:28:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix -fSAN in AnalyzeFile mode

The exception that a PV relates to currentMove rather than forwardMostMove
applies not oly in AnalyzeMode, but also in AnalyzeFile. Furthermore,
PvToSan did not properly restore the pushed game tail in this case.

2012-12-08 16:02:09 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Improve scaling of border bitmap (WB)

The StretchBlt mode is set from dither to delete.

2012-12-05 16:34:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement use of pause / resume protocol commands

Engines that implement feature pause=1 will be paused during their move
on a pause event; pondering engines will be controlled either through
'pause' or (if they don't support that) 'easy', which both should work
instantaneously. If the thinking engine does not support 'pause', the pausing
will be deferred to when it produces its move, and is implemented by not
relaying the move, and switch off pondering for both.

2012-12-03 12:58:36 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix Loop-Chess promotions

Loop Chess is not a supported variant, but hould be playable as Crazyhouse
with an altered pieceToCharTable, not defining the shadow promotion pieces.
But with legality testing on promotion to shadow piece would take place
even if the shadow piece was not defined.

2012-12-02 22:44:55 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix move highlighting with animation off

In WB the moving of SetHighlights to after the animation had broken the
highlighting of engine moves, because it was also moved after DrawPosition.
While it is DrawPosition that actually draws the highlights. Now it has been
moved to just before DrawPosition.

2012-12-02 11:09:14 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Start browsing in currently-selected folder (WB)

The folder-browse dialog always started at My Computer, while file browsing
started in the globally last-used folder (which might not be related at all
to the file entry we are now browsing for).

2012-11-29 23:38:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement book-creation functions

A new menu item triggers conversion of the currently loaded PGN file
to a Polyglot book, saved with the GUI-book filename. A (volatile) option
-mcBookMode alters the probing algorithm to build a book from scratch by
playing games (and using a form of learning).

2012-11-29 22:23:44 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use colors in Board-Options dialog also for font pieces (WB)

The piece color settings now control the pieceColor or fontPieceColor
settings, depending on the setting of -usePieceFont.

2012-11-29 22:14:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement auto-creation of ICS logon file

Under control of the new option -autoCreateLogon (which can be set from
the ICS Options dialog) the first two lines in response to the ICS "login:"
pompt will be saved on a newly created logon file (if logon from such
an existing file failed).

2012-11-29 21:56:02 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add Themes dialog (WB)

This dialog, done by the generic popup, contains controls for many settings
that so far could only be controlled by options. It also introduces the
concept of 'themes', sets of options stored in the multi-line option
-themeNames.
  Add some dummy routines to suppress compile errors in functions that
cannot be called yet in XBoard.

2012-11-29 21:32:03 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow external piece bitmaps and board border (WB)

The -pieceImageDirectory is now also used for WinBoard, to indicate
a directory of .bmp files, used to replace the built-ins. The outline
and solid bitmaps can be full-color. This allows winBoard to use the
WinBoard-zeta graphics. A new option -border can indicate a bitmap file
used to draw a half-square-wide border around the board.
  A white background has to be drawn underneath the black pieces, to avoid
color-interference with the board, just like happens for the white pieces.
These backgrounds now always use bright white, rather than -withePieceColor.

We still have to work on the scaling of the zeta (600x600) bitmaps to
the actual board size, as for some bitmaps the stratchblt is ugly.

2012-11-29 21:05:15 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add 'Continue Later' button in Tournament dialog (WB)

This button makes it possible to accept the values specified in the
dialog without immediately starting the tournament (as OK does),
so you can re-open the dialog later, and OK it then.

2012-11-29 20:25:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Load opponent logo based on handle in ICS play (WB)

The logos for handles on FICS are sought in folder logos\freeches.org\*.bmp,
etc. If no logo for the handle is found there, the logo of the ICS is
displayed as usual.

2012-11-19 20:35:05 -0800 Daniel Dugovic <dandydand@gmail.com>:
Fix configure script for --enable-zippy  (tiny change)

reported and patch by Daniel.

edited by Arun Persaud:
- also fixed #ifndef ZIPPY -> #if !ZIPPY
- didn't change #if -> #ifdef

2012-11-10 00:12:34 -0800 Arun Persaud <arun@nubati.net>:
don't define X_LIBS when using gtk-frontend


2012-11-07 22:16:09 -0800 Arun Persaud <arun@nubati.net>:
updated po/pot files; added new frontend files


2012-11-07 22:14:20 -0800 Arun Persaud <arun@nubati.net>:
fix configure script for --with-Xaw and --with-gtk

made Xaw the default and included xaw or gtk sources as extras
in case the other frontend is selected for make distcheck

2012-11-07 21:13:38 -0800 Arun Persaud <arun@nubati.net>:
new version number for developer release


2012-10-31 09:55:02 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Draw frames around memos and listboxes


2012-10-30 17:39:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Adapt lineGap during sizing


2012-10-30 15:04:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix clock highlighting


2012-10-30 10:59:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix Chat Box

The genric TypeInProc is re-instated, and replaces ICSKeyEvent as primary
handler for special keys in one-liner text edits.

2012-10-29 19:46:27 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Pay attention to NO_CANCEL dialog flag


2012-10-29 14:18:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix clock clicking with GtkEventBox

Like in WinBoard the button-3 case is now handled in the primary
event handler (and communicated to it in a kludgy way). It would be
better if this was absorbed in ClockClick().

2012-10-28 22:25:22 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix logo placement

Graphs were not recognized as possible SAME_ROW elements. A Graph requesting
FIXED_H (which only the logos did) is now packed into a (borderless) aspect
frame.

2012-10-25 23:04:42 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add window positioning

Sticky windows now sort of works, but needs unexplained fudge factors.
Reopening a persistent dialog centers it on the board, and disobeys
the positioning command. The WindowPlacement of the BoardWindow was
again added (it was commented out during development).

2012-10-22 22:41:14 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make board sizing work through subtracting fixed height

There is now no attempt to give a size to the board drawing area, so it
can later be sized as small as we want. The frame width is determined
by subtracting the nominal board size from the actual window size,
(because the clocks will have that width, and the board will startas 1x1),
while the vertical margin is determined as the difference between the
bactual window height, the drawing-area height minus a fudge of 25 pixels
to compesate for the erroneously allocated blank space below the board.

2012-10-22 21:09:51 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix warnings

The highTextStart/End are now declared in engineoutput.h, shared between
nengineoutput.c and xengineoutput.c. Unused variables were removed.
Also fix warnings in xboard.c and xoptions.c.

2012-10-22 17:40:08 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Delete emptied front-end files, and move rest to gtk directory

Remove #ifdeffed-out Xt code that has GTK implementation. The xgamelist
and xhistory have been completely cleared off content, and were removed.

2012-10-27 00:12:42 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add copy-paste

The code from gtk-xt could be used with almost no modification.

2012-10-21 09:09:01 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Some experimenting with sizing

Does not work as intended yet.

2012-10-21 23:04:49 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add task-bar icon

Funny enough it was necessary to swap the two svg icons to make this work!

2012-10-20 10:29:37 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make some tall dialogs multi-column

A dummy button was added to the last row of New Variant to make the
number even. A legality-test warning as put in the New Variant dialog
Fix width of tourney-file in Match dialog

2012-10-20 21:14:33 -0700 Arun Persaud <arun@nubati.net>:
updated some icons to SVG


2012-10-20 19:57:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add displaying of icons

A new Option type, 'Icon', was added for this as in GTK Icons and Labels
need different types of widget. The icons are now svg, so we could
remove the icon pixmaps.

2012-10-20 14:25:41 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix button bar


2012-10-20 14:03:48 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add BarBegin, BarEnd options

This makes the button bar display correctly. Also fix v-sizing of menu bar.

2012-10-20 10:01:35 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add listbox double-click callback

This function was formerly performed by WheelProc.

2012-10-19 17:29:40 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add hiding / showing second Engine Output pane

The handle of the GTK table for the second engine is stored in the
EndMark handle by GenericPopUp, so it can be used later to hise/show
that table.

2012-10-19 17:15:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Use different tables for different dialog columns

Making the same table wider (in steps of 3) to get multiple columns
does not work, because it forces options to align vertically. This
wrecks dialogs like Load Engine, where one column contains a very
high option (listbox). Now differnt tables are created for each column,
packed in a new itermediate hbox. In case of the Engine Output window,
a vbox is used instead to cause vertical stacking.
  Only multi-line text-edits and listboxes are now allowed to take up
vertical space changes, while only the middle colum of the table
can take up horizontal size changes. Within packing boxes space is
equally distributed.
  The labels above the particiant-selection widgets had not the same width
as the textview / listbox, leading to misplacement of the second label.
  For Engine Settings the spontaneous breaking into columns did not
involve a SAME_ROW flag, so the 'columns' were stacked vertically.
In addition the columns were too tall for GTK. They are now 20 options max.

2012-10-19 13:46:37 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Deselect first char in Move Type-in and ICS Input Box

After popup the Move Type-In had the typed character in it, but it was
selected, so that typing a second character would erase it again.
Same for the ICS Input Box. A prototype for CursorAtEnd is now also added.

2012-10-19 13:33:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Close Move Type-in on Enter

The code is squeezed into the ICSKeyEvent callback.

2012-10-18 21:57:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add access routines to checkboxes and FocusOnWidget

The <Enter> handler of the filter field needs it to return focus to
the listbox.

2012-10-18 21:42:49 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add game-list callbacks

The callbacks for listbox and filter text are treated by the same callback,
which does both key presses and button double-clicks.
Giving focus back to the listbox after filtering does not yet work!

2012-10-18 16:27:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:

Add Shift detection

The state of Shift and Ctrl was only probed on button clicks, so it
is now read out of the button-event struct in the relevant button handlers.
For backwad compatibility, they store it in a global, so the routine
ShiftKeys can take them from there.

2012-10-18 12:35:20 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remove some unneeded low-level X11 code

Things like tabbing between controls, mouse-wheel scolling etc. are all
automatic in GTK, and thuse don't need to be ported.

2012-10-18 10:12:27 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add file browser

The gtk-xt code for browsing in response to menu items rather than dialog
browse buttons) was grafted. It seems desirable to merge the two browsing
functions, though. Pass extra params used by Xaw to FileNamePopUpGTK.
The code was altered to use DelayedLoad.

2012-10-18 09:54:41 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix ListBox, and add some support routines

The srolled-window for the listbox used a uninitialized variable for its
width, causing a crash. Now it pays attention to the Option.max and .value
size hints. The access routines were copied from gtk-xt. HighlightWithScroll
could just a wrapper for HighlightListBoxItem, as GTK auto-scrolls.

2012-10-17 20:01:37 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Connect CommentClick handler

This can make use of generic memo callback, so it could be entirely
backend. Therefore it was moved to dialogs.h. As it shared a global with
some other back-end popup routines to remember the current move, these
could now be moved out of xboard.c too. (Well, not so for the X11 front-end,
so it has now been put in a header. :-( )

2012-10-17 19:41:11 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix animation

Because FrameDelay does block the event loop, even though it releaes the
CPU, expose events start to lag behind the actual drawing. By combining
expose events for overlapping squares, rather than decompose them into
3 rectangles, this problem seems to go away. But only if there is an
extra exposure on the squares to be drawn also non-overlapping frames
will be properly drawn (?!).

2012-10-17 14:40:59 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement highlighting in engine output by through generic method

HighlightMove was made generally available for all text. It is now just a
wrapper for the generic HighlightText, and could be moved to the back-end.
(This requires the initialization to be widget specific, and the flag
indicating it has been done is now stored in the Option.min field.)

2012-10-17 14:33:28 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Let engine-output memos use new generic callback


2012-10-17 13:53:03 +0200 H.G. Muller <h.g.muller@hccnet.nl>:

To have access to the textview, its handle is now stored in the
Option.textValue field.

2012-10-17 13:11:23 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add highlighting in move list

For now it is assumed the normal background will be white (for clearing
the highlight).

2012-10-16 19:44:40 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make generic memo-event handler, and connect history callback

Large text widgets can now define a user handler in their Option.choice
field. If they do, agneric callback is added tothem, which catches mouse
events. Button release and pointer motion pass their coordinate and type
to the specified user routine. Button presses in addition retrieve
the text from the widget, set the cursor in it to the clicked point,
and convert it to a character position, also passed to the user.
  The user is responsible for ignoring events he is not interested in.

2012-10-16 15:58:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add key-handler for ICS Input Box

In contrast to the X11 code, all intercepted keys are now treated by
the same callback. The ICS Input Box callback triggers on Up, Down and
Return key, and refers to these symbolically.

2012-10-16 13:28:32 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add text insertion in engine-output memos


2012-10-16 09:34:02 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Append recent engines to engine menu

This is now entirely moved to the back-end, by doing it in the table
from which the menus are later generated. The special callback for engine
items is abandoned, and the euProc for such items is left NULL to flag
that RecentEngineEvent should be invoked with the applicable engine number.
To calculate the latter a global variable firstEngineItem is dynamically
set to the length of the regular engine menu.

2012-10-15 22:17:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:

Attach expose handler and connect to mouse events

The GraphExposeProc is conected to the Graph widgets. A gdk draw routine
is used to copy the buffer bitmap to the display. It is also connected
to button and motion-notify events.
  In this version the board can be fully operated with the mouse.

2012-10-14 22:00:14 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Transfer most available gtk-xt code to xoptions.c

GenericPopUp and PopDown are grafted from gtk-xt into gtk2.
The version compiles, but segfaults before doing anything, with error
messages about unexpected cases in GenericPopup for Graph and PopUp Options
of the main board. The spin options need special treatment in GetWidgtText.

2012-10-15 11:41:33 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Give LoadListBox two extra parameters

It often occurs that we just want to swap two elements, and reloading
the entire listbox would be a very inefficient way to do this in widget
sets that allow access to a single element.

2012-10-14 20:36:34 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remove all X11 code by #ifdeffing it out

With #ifdef TODO_GTK we disable all X11 code, in order to get a compiling
X11-free version. The disabled sections can then be replaced by code
for another widget set, the X11 version still showing what it was supposed
to do.

2012-10-14 17:37:18 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Move timer functions to new file xtimer.c

The timers for the clocks, periodic analysis events and ScheduleDelayedEvent
go into a separate file.

2012-10-14 15:31:56 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make xevalgraph.c backend

The only front-end stuff left in xevalgraph.c was an unnecessary reading
of the window size (which could be obtained from the WindowPlaceent struct),
and drawing (all cairo now). The drawing was moved to draw.c, and the
remaining part renamed nevalgraph.c.

An attempt to list them in a less chaotic way.

2012-10-14 14:34:09 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Cleanse back-end code of all references to X11 types

When compiling for X11, common.h #included X11/Intrinsics.h so that
X11-specific data types could still be used throughout the back-end part
not shared with WinBoard. By temporarily disabling this, error messages
could be generated on all such occurrences, and were then solved. This
included the following:
  The InputSource struct is not uses in usystem.c at all, and its definition
could be moved to xboard.c. InputSourceRef, which logically should heve been
defined as (InputSource *), is in reality (void *), so the back-end can
pass it around.
  Some non-platform-dependent stuff of general interest had prototypes
(or external vars) in xboard.h. This is now moved to a new header xboard2.h,
to allow it to be shared without bringing in X11 dependence.
  The EngineOutputProc was defined inconsistently, but the header was not
sufficiently shared to flag this error. This has been repaired now, by moving
the template to menus.h.

2012-10-14 13:39:47 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remove xedittags.c, .h from project

Move MarkMenuItem to xoptions.c

This to make xoptions.c completely independent from the inclusion of
frontend.h. The prototype is moved to menus.h.
  Loose end: DrawPosition in board.c does not see the prototype.
Very suspect that it wants to see it. Why would it have to correct the
flipView setting??? Better se to it that it is correct to start with!

2012-10-14 12:14:07 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
move testing for no options to back-end

The test if an engine has options and display a note instead of
the Engine Settings dialog when this is not the case is moved
to outside of GenericPopUp, to make the later independent of calling
other routines.

Move ICS-engine analyze and AnalyzeGame code to shared back-end

This code was still duplicated between WB and XB in the front-ends.
Because of its incorporation in AnalyzeModeEvent the 'middle-end'
function AnalyzeModeProc could be eliminated. AnalyzeModeEvent was made
to return an int to flag its success, and keep the JAWS code based
on it out of XBoard.
 The AnalyzeGame code  is now incorporated in AnalyzeFileEvent().

Add configure switches for Xaw vs GTK.

This patch is an adapted version of the one Arun made at the end of the
gtk2 branch. It uses the exact same version of his configure.ac, but the
Makefile.am is adapted to the situation in master at the beginning of it,
after duplication of the X11 front-end files in the xaw directory for
preserving them, while the versions that will be modified to GTK front-end
are still in the xboard directory.

The extra pixel that is requested in sizing the board window back to
an available size because we ofte get one less pixel than we ask for

Increase drag delay too 200 msec

On my slow laptop it can take more than 100 msec to reallocate bitmaps
in the generic expose, with as a consequence that the DelayedDrag event
is not processed before the timeout expires. The timeout event then triggers
a redraw, which again takes so long that the timeout expires before the
event to reset the timer could be processed, and this just perpetuates
itself, leading to a large series of queued redraws, and a long waiting time
for an image to appear after the sizing stops.

Make Piececolor options work on png pieces

The scaled, antialiased bitmaps are now colored according to the option
settings. This is done by decomposing every pixel in a white, black and
transparency component, which is possible because the opacity is
directly give in the alpha channel, and black originally was a hard zero.
So what you se in the red channel must be white (as the original white
was #FFFFCC), and the rest of the opacity must be due to black.
  The color to be replaced (white for the white pieces, black for the black
pieces) is then replaced by the original weight of this color times the
color from the option.

Cure flashing of piece on from-square

In a drag-drop move the piece was flashed on the from square after the

Allow resizing of board window

In full png mode the size of the board window is no longer locked.
After resizing, the square size is calculated as the largest one that
would fit the window, and the window is then shrunk around it. To prevent
excessive redrawing during sizing, the redraw is delayed by putting it
in DragProc.

2012-10-05 10:41:02 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Switch to using 64x64 png images

The bitmap scaling works better when the needed factors are not too large,
as the svg rendering's anti-aliasing did not blur more than 1 pixel.
So after shrinking too much the images are not effectively anti-aliased
anymore.

2012-10-05 10:16:47 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Maintain in-memory copy of the board image

As reading back from the xlib-surface proves incredibly slow (cairo probably
converts the entire image from Xt format to cairo format when we set it
as a source, even though we only want to read a few dozen pixels), we now
keep an exact copy of the board image as a cairo bitmap in memory. This
restores the speed of the animation, but unfortunately leads to awful code.

Resolve conflict between -mps and -inc options

The age-old problem that a persistent valid -inc value will cause -mps
to be ignored is solved by the kludge of storing these two as a single
option (-mps) in the settings file, and declaring the other (-inc) volatile.
The range of negative numbers (invalid as -mps value) was available for
that, and now is used to store the negated value of -inc in msec.
For backward compatibility, specification of -inc causes interpretation
of -mps in the old way. The forcing of -inc to -1 in the master settings file
could be safely removed because of this change, so that the time increment
now is a persistent option.

Allow ICS nickname as positional argument

If an argument is encountered that is not preceded by an option name,

Allow Analyze Game to auto-step through entire game file

If the game index is set to auto-increment (-lgi -1), the Analyze Game
function will automatically load the next game of the current game file
(starting to auto-play/annotate that) when the end of the current game is
reached. This flushes the annotated game if auto-saving was set,
so that eventually all games in the file will be annotatd and saved.
  The game index is automatically set to auto-increment when we load
a file while in Analyze Game mode, but switching this mode on while a game
is already loaded will stop at the end of that game, as usual (if -lgi was
not explicitly set).

This patch still does that by default, but if the argument ends in .fen, .epd,

  In addition, an implied -lpf or -lgf argument also imply the option -viewer,
which inserts the -viewerOptions string into the command line, and proesses it
as options. A new option -tourneyOptions is similarly inserted for an implied
-tf argument. These strings should contain all options needed to start XBoard

Port chat boxes to XBoard

A new menu item Open Chat Window is added to the View menu. It opens a
window that can handle 5 chats. A row of buttons on top selects which is
the foreground chat partner, to which we type, and whose incoming messages
will be displayed in the memo. The leftmost 'button' is not really a button,
but a text edit, and the active partner is displayed there (so it can be
altered). Selecting another chat partner through a button, moves that partner
to the text-edit, and reshuffles the buttons. Incoming messages in a chat
that is not foreground make the corresponding button color orange.

New options -logoSize and -logoDir are added. The former enables logo display,
when non-zero and not too big. The latter is used by -autoLogo. The options
 -firstLogo and -secondLogo also work. Problem is that the clock height
is larger than the logo height, and for now a nasty trick in GenericPopUp
is used to position the next element (message field) w.r.t. the clocks,
rather than the last element of the row above (the logo): in case of a
SAME_ROW Graph element, 'last' is kept at the previous element.

Some of the function names used in the refactored X11 front-end collided
with Windows system names from winboard.h, or with names of internal routines

These were renamed. Some prototypes in engineoutput.h contained X11 types,
and they were moved to xboard.h.
  In addition, two menu-item names were corrected to two-part names.

Offer primitive paging in file browser

If there are more than 1000 files that would have to be displayed,
the number will be limited to 999, and a 'next page' entry will appear
at the bottom. Clicking that will give you the next group.
 This is an emergency measure only, as it interferes with sorting
(grouping is based on order inside the directory, i.e. kind of arbitrary,
and sorting is only done within a group.) There is no such thing for the
folder list yet. There is no way to go back to a previous page, other
than closing and re-opening the browser, or selecting another file type.

Implement automatic partner observe

Starting a game, or starting to observe one, now automatically issues a
'pobserve' command if dual-board is switched on, so that the partner game
will pop up in the secondary board (assuming it is bughouse).
 The secondary board now displays the players in the title. (This (lightly)
breaks WinBoard again.) When the primary game ends, the secondary board
closes automatically. Initial sizing of the board is repaired, and now uses
the actual current board size, rather than the initial size of the main board.

Suppress testing for availability in bughouse drops

Give up on testing legality of bughouse drop moves; this only causes problems,
because the move list sent by the ICS is not accompanied by holdings updates.
So XBoard parses it thinking the holdings are empty, making every drop move
an ImpossibleMove. Bughouse can only be played on ICS, and we might as well
trust the ICS that it will only pass us legal moves. A user should not be
able to enter illegal drops; unavailable pieces cannot be grabbed from the
holdings, and typing is diverted to the ICS directly (which would reject the
illegal drop without XBoard even knowing about it).
  Also improve switching to bh/zh, based on drop move in initial board.

Fix promotionPopDown on new move entry

The promotion popup is non-modal, and old XBoard versions popped it down
as soon as the user clicked the board, so he could just enter a new move
to abort the promotion. This was broken in the new version, because the code
to do the PopDown and abort in HandleUserMove had not been ported.

2012-04-13 18:38:51 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Use in-place sweep-selection for click-click under-promotion

With detour under-promotion a piece cycles through all possible choices
during backwards dragging. But in a click-click move there is no dragging.
This used to be solved by letting the second click start a drag event of
the default promotion choice, which you could accept by immediately
releasing the mouse button, or drag around to change it first.
 The dragging in this case seemed a little unnatural, because the to-square
was already indicated by the down-click. So it has been changed now to the
promo choice appearing on the down-clicked to-square, followed by
EditPosition-like sweep-selection on that square when one wants to under-
promote. The move is always accepted no matter where the up-click takes
place, except when it takes place on the from-square (which offers a last-
resort abort possibiliy).
 Note that click-click promotion is essential in variants where it is not
obvious from the from-square alone that a promotion is imminent, but where
it depends on the to-square. (Such as Shogi.) There drag-drop detour under-
promotion is not possible.

2012-04-13 16:05:16 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Improve arrow drawing

The arrow is now erased together with the border highlights, by marking
the damage it did, and then doing a selected redraw of the board to let
the damaged square be re-drawn. Highlights of a previous move are now
cleared on the down-click that selects a new piece, so there never is an
arrow to infavorably interact with animation of dragging.

MarkTargetSquares does no longer have to force to complete redraw.

Move clearing of target squares to after drag end

A dragged piece that would partly overshoot its destination into a square
with a marker would effectively protect that marker from erasing, when the
erasing was done before the piece was released, because redrawal after the
move only would draw the target square. (Unlike erasing, which forces a full
redraw.)

Redo main board window with generic popup

Some of the improvements in GenericPopUp (committed earlier) were added
especiall for this (menu and box Option types), and the commits that used
them to make a fully functional board, listed below, were collapsed into
this one.

This uses the new box and menu features of the Generic popup.
Make option table shadow board consistent with refactor
Do main menus in shadow board
 The board made by GenericPopUp now also has (functional) menus. The Expose
 callback now also uses the new format (passing coordinates).
Use BoxEnd callback to decide about smallLayout
 The shadow board now dynamically decides whether it should use smallLayout
 positioning of the title-in-window widget, using a callback in the BoxEnd
 option for the menu bar: If no reasonable amount of space is left behind
 the menu bar, the title is forced under the clocks (smallLayout).
Do some mouse handling on shadow board
 Only button 1 events for now. We have to keep track if the button is down!
Connect button 3 to shadow board
 For now only for piece and PV manipulation: no context menus yet
Symbolic reference in option formatting
choice <-> textValue xboard.c
Improve expose callback shadow board
Implement context menus of shadow board
 This uses the new generic PopUp option
TopLevel xboard.c
Make mock-up board available through menu item
Make clocks of shadow board sensitive to clicking
Make button bar of shadow board operational
 The back-end Event functions are specified as user callbacks directly;
 this is not very clean, as they are parameterless, but called with an int
 argument. This should have no bad consequences, though.
Switch to using shadow board as main board
 The menu marking and enabling had to b switched off for this, as it
 only worked on the old menus. Remove HandleUserMove.
Deleting of unused shell variables, clocks to dialogs.c
Move BoardPopUp to dialogs.c
 This required passing on fome front-end vars as parameters, and returning
 apointer to the option list, to make the handles available in xboard.c.
Simplify InitDrawingSizes
 Now that all widgets of the main window are properly chained, there is
 no need to resize them when the board format changes: setting a new width
 for the shell suffices.

Redo Eval Graph with generic popup

The Graph option of the GenericPopUp is used to implement the Eval Graph.
Compared to the previous implementation, which was drawing directly in the
form widget, the new one has one extra widget layer, but that did not
affect the code anywhere. Adapt eval title to width of eval graph.

Major refactoring of GenericPopUp

Allow more transient dialogs in GenericPopUp
Remove grab from promotion popup
Fix other generic popup over transient popup
 To use the generic dialog generator for 'asynchronous' popups (Ask Qustion
 or Error popup caused by engine), the currentOptions setting has to be
 restored for the combo and checkbox callbacks of the transient to still
 work after the asynchronous dialog returns. Note that only transient dialogs
 can have check and combo controls.
Make generic calcel button suppressible
 Also #define some more symbols for Option.min flags,
 and move them to dialogs.h.
Change TypeInProc to general OK handler
 The move type-in now has its own option list, to distinguish it from
 the ICS input box, and give it its own OK handler. Rather than having
 the translation for <Enter> on the text widget call TypeInEvent directly,
 we let it call GenericCallback, which calls GenericReadout, which calls
 the OK proc, which does the job.
  To be able to call GenericCallback from the TypeInProc, the recognition
 of OK and cancel buttons had to be changed. This because it was too difficult
 to arrange the calling widget had label OK or cancell. So these buttons are
 no longer recognized by name, but by the option number passed as client data.
 (This solves the problem that a user could not make buttons named 'cancel'
 or 'OK'.)
Make Cancel button optional
Fix closing multiple popups of same kind
 The GenericCallback figures out its own shell, so all buttons of
 multiple dialogs keep working. External calls to PopDown only work
 on the lastcreated instance of that kind, though (including those from
 the Delete Window button, which can do 'cross-closing'). shellUp is now
 a counter, and PopDowns are only prevented when it reaches 0 or the
 current shell does not exist. (To know this, PopDown now resets shells[n]
 to NULL when is shell is destroyed.
  Beware of double PopDowns (through OK procs); they wreck the system.
Fix Delete Window button of multipe ErrorPopUps
 The action routine for handling the Delete Window now pays attention
 to the shell widget that the system passes to it, and temporarily
 replaces shells[n] by it to let PopDown act on the proper instance.
Add ListBox dialog type to GenericPopUp
Fix vert sizing of ListBox
Put listbox widgets in viewport
Put listbox in viewport
Improved xoptions.c support for focussing and listboxes
Fix OK-row button positioning
Let GenericPopUp take parent and modality as arguments
 This makes the code a bit more explicit and less kludgy. It also becomes
 possible to call the same dialog (e.g. Load Options) from the main menu
 and from another dialog (e.g. the Game List).
Support scroll function for generic popup listboxes
Fix scrolling
Move HighlightWithScroll to xoptions.c
Change scroll algorithm
Add mouse-wheel scroll to generic list boxes
Implement tabbing between text edits
Implement same-row text labels in generic dialog
Allow labels to specify their chaining in generic popup
 The opt.min variable is used to specify the chaining: 0xF0 are the bits
 for (left, right) chaining of the left side (0xC0) and right side (0x30).
 The 0xC bits determine top or bottom chaining of the entire label.
 Without anything spcified (0), the chaining is XtRubber.
 TextBox options can also specify top-chaining of their top. All this was
 needed to allow decent implementation of the Engine Output window with
 the generic popup. (Although tags and comment popup ca benefit from the
 latter feature.)
Let GenericPopUp support a Graph option
 The Graph option results in an area where one can draw something. It is
 positioned / chained similar to Label options. A handler for expose events
 can be specified in the textValue field of the option.
Implement box widgets and menu buttons in GenericPopup
 To enhance the capabilities of GenericPopUp such that it could create the
 main window, it needs to be able tha packaging of controls into a box widget
 (for mennu and button bar). Menu buttons are also required elements
 (although they do look a lot like comboboxes?) Option types BoxBegin and
 BoxEnd can now be used to bracket a group of controls that will be put
 in a box widget. (Cannot be used recursively!) The positioning of the box
 is similar to that of a Label, and is specified in the BogBegin option.
  The code to shrink the menu buttons to fit is also incorporated, to act
 on any box widget: if the BoxBegin option specifies a width, the elements
 in it are shrunk to meet the requirement. Otherwise the box just gets the
 size of the sum of its children (plus spacings).
  Label options can now specify a font, casted into their textValue field.
 (This is needed to get the proper size for the clock widgets.)
Implement callback in BoxEnd options
 BoxEnd is a pseudo-option, to trigger packing the preceeding ones in
 an earlier-opened box widget. In the process it calculates the size of
 the box widget (and trims it if a size was specified for it in the
 corresponding BoxBegin). The Option.target field of BoxEnd is now
 interpreted as a callback, which can be use to take decisions based
 on the determined size for the remaining options in the list, before
 these are processed b GenericPopUp.
Refactor xoptions.c
 Make a subroutine to set args shared by almost all widgets. Swap meaning
 of '1'-bit in option.min flag of Break option, to be consistent with
 SAME_ROW interpretation in other option types.
Make option tables consistent with refactored GenericPopUp
 The flag for stacking in the Break option needed to be inverted, and
 the BoardPopUp needed to pass the font in another field. Better use was
 made of the improved chaining options too.
Improve Graph-option event handling
 The user-supplied callback now gets 3 arguments passed: the event type
 (0 = pointer motion, 1...5 button press, -1...-5 release, 10 = expose),
 and two coordinates. For ouse events these are the pointer (x,y), while
 for expose events they are the window size (w,h). The callback is now
 specified in the option.target field of the Graph option.
Store engine options in malloc'ed memory
 The Option.name field has been re-declared as (char*),  from (char[MSG_SIZ]).
 There are still MSG_SIZ chars allocated irrespective of actual size, because
 the field is also supposed to store the textValue, which can be changed by
 the user. But at least it means that unused options of the generous list
 now don't waste much space. (And the prparated Option tables in dialogs.c
 will shrink by a large factor as well.)
Improve GenericPopUp ComboBox handling.
 The dialog type is now passed to the combobox callback as well, and this is
 used to really figure out what option it is called for.
Allow numeric comboboxes
 When no list of strings is given in Option.choice, the target is assumed
 to be (int), and the number of the slected entry is stored there. Also
 adapts the Label options that act as fillers to the new method for making
 dummies (namely NULL in the Option.name field).
Put comboCallback in Option struct
 Rather than having a general comboCallback variable for the entire current
 dialog, each ComboBox option can now specify its own callback in the
 target field of the option: the COMBO_CALLBACK bit of Option.min indicates
 whether the target is a variable to be set or a callback. The callback can
 still fetch the choice from the values array.
Allow generic CreateComboPopup also to do main menus
 An extra parameter to CreateComboPopup determines if the menu texts
 should be taken from a list of strings (the old method with engine-
 supplied choices), or from a menu table of MenuItems. It can now also
 recognize "----" as a menu break, and keeps margins (for the marking).
Make subroutine for determining curren combo selection
Various fixes to GenericPopUp
Delete one border-width setting
Fix max nr of args in GenerocPopUp
Fix button release events of Graph options
Fix generic Graph callback pointer motion coordinates
Make all format referencing in Option tables symbolic
Let Option.choice define menu texts, rather than Option.textValue
 This is more logical than ussing textValue for it, because choice already
 has the correct (char**) type, while textValue was (char*), and needed
 casting everywhere. Note that for engine options, the fields were the
 same anyway, so no back-end change was required. The textValue now
 contains the (casted) list of actual string values, where these are
 needed. (But for numeric and function menus they aren't.)
Add PopUp Option type
 An new pseudo-Option is defined, to add a popup menu to a previous Graph
 option. The actual popping up is done by the expose handler.
 The function XUngrabPointer is the key to success here. A PopUp option
 specifies a callback for handling the selection from the menu, which will
 be called with the option number, exacty as with ComboBox options.
Update option explanation in dialogs.h
Make Spin and CheckBox callbacks pass dialog number
 No longer rely on 'currentOptions' for getting the option belonging to
 the callback, but get it out of the dialogOptions array indexed by dialog
 type. This way things cannot be messed up by an asynchrounous error popup.
 It also means that it is now save for non-modal dialogs to use these options.
Use button widget for text behind checkbox
Let listboxes use general formatting hints
Let GenericPopUp option always finish last pane after Break
Allow LisBox to specify select callback in Option.textValue
Use double-click to trigger ListBox callback
Make ListBox callback re-entrant
Fix multi-line Label options
Separate CreateMenuItem out from CreateComboPopup
Chain checkbox texts entirely left
Allow a user-specified callback to Label options
 This is needed to implement the clocks. Let the CheckBox callback handle
 it. For now ther is no distinction between different mouse buttons.

Prevent double PopDowns

Some DialogOK functions ordered an early PopDown themselves. This,
however, resulted in PopDown being called twice when they returned TRUE.
This interfered with the new system for allowing multiple instances of
the same dialog. So these functions are now fixed to suppress the
standard PopDown by always returning FALSE.

that have to handle the sound themselves.
  The usystem.c file contains all non-X Unix-like stuff, such as fork,
pipe, system, getenv. I also contains some color parsing for the xterm
colors. This stuff could be useful on platforms that support Unix-like
system calls.

Back-endize atomic explosions
Back-endize DrawArrow and DrawDragPiece
 DrawDragPiece now calls DrawOneSquare with argument EmptySquare in stead
 of the X-type referring BlankSquare. A new wrapper DrawPolygon fixes
 DrawArrowBetweenPoints.
Move board-drawing logic to new file board.c
 All X-independent drawing logic (board, squares, arrows, highlights,
 some animation stuff) has been extracted from xboard.c, and moved to
 a new file board.c, which is back-end (but unshared with WinBoard).
 A new header board.h defines the cross-references (which of course
 required some functions to be no longer declared as static).
  A bit of code was moved from DragPieceBegin to BeginAnimation, which
 now has an extra argument to indicate which piece should appear from
 under a dragged piece. This makes DragPieceBegin free of XCopyArea calls,
 so it could be moved too.
Make board.c truly back-end
 Get rid of all X data types. For this the AnimState struct had to be
 redefined: the GC and Pixmap was taken out and put in front-end arrays
 indexed by anim agent (game and player). For this indexing a new enum
 was defined. The XPoint type was also replaced by our own type of an
 int pair (which is nasty, because the int size could be different).

Refactor menu code, and move it to menu.c

Supply new method for key binding
 It is annoying that every menu item needs its X-specific handler routine,
 because this handler has to be registered to X for becoming eligible as
 a key binding. Another disadvantage of this method is that the user wanting
 to make the binding has to know the name under which the menu function
 is registered (e.g. FlipViewProc).
  A new method is now made available, which uses only a single (X-specific)
 routine, registered with X as "MenuItem", as generic key-binding handler.
 The bindings can then be made by the user specifying "MenuItem(FlipView)".
 This requires a new list of potential bindings, which should be filled
 by the menu-creation routines. (Currently only contains only a predeficed
 example.)
No longer register all MenuProcs with X
 The list with available menu procs is moved to the user-maintained
 menuItemList. Only QuitProc had to stay registered with X, because it is
 used in CatchDeleteWindow. (So it is in both lists now.) In the future,
 most of the list can be built automatically from the menu tables.
Alter type of MenuProcs to void(void)
 By getting rid of the argument list with X-types, most menu procs can
 become back-end. In the cases of ManProc and QuitProc the original
 version had to be kept as well, because in ManProc the argument was
 actually used (with key binding), while QuitProc is used for delete window.
Remove now unnecessary menu wrappers
 Now the MenuProc have an empty argument list, those that also call a
 single 'MenuEvent' without arguments have become completely redundant,
 and have been taken out of the loop by calling the corresponding MenuEvent
 directly.
Build menuItemList from menu tables
 Rather than having an initialized table of name-proc associations (which
 used to be the X registrations) for the menu items, we now build the list
 during menu cration from the menu tables. The menu "ref" is now used as
 proc name. This means the old MenuProc names used in the predefined
 key bindings had to be changed to conform to this. Note that the bindings
 would slice up names containing spaces in several parameters, so in the
 translations the spaces were squeezed out of the item names. This requires
 a hand-written comparison routine Equal() to identify the binding.
Remove prototypes of deleted MenuProcs
Move prototypes of platform-independent MenuProcs to menus.h
 Create a new header file for the menu stuff, so that we can move
 the corresponding handler routines out of xboard.c to a back-end file.
Extract back-end code from menu creation
 The menu tables and code to interpret them is moved to a new file menu.c.
 Only basic fuctions for creating a pop-down list and for adding an item
 to it remain in xboard.c.

when hand-loading engines.
  Some of the rare options were not swapped either, and would thus

When an engine reports a fail low as thinking output, and then re-searches

Dragging a piece by double-clicking it on the from-square in analysis mode
will not perform the entered move, but send an exclude or include command
to the engine for that move (provided the engine enabled this with
feature exclude=1), depending on if the move was already excluded or not.
To this end a map of excluded moves is kept, and cleared when we move to
another position through moving, undo, setboard or new. The user can see
whether he included or excluded the move, as exclude uses premove highlights.
  Commands "exclude|include all" are sent when we throw a double-clicked
piece off board (vertically or horizontally, respectively), but after
exclude all the most recent PV move is included again.
  Remaining problem is that promotions can only be excluded.

The ProcRef and InputSource are now also cleared, and just to be sure there
are no surviving adapters, the child is killed when engine startup fails.

Inform user in EditPosition mode how to clear board

With -pieceMenu false the board is cleared by clicking the clock, but
since this is impossible to guess, it is now printed in the message field.

Fix fall-back on -ncp mode

When the requested engine could not be started, the user still had to
wait for the feature timeout to expire before the UI was re-enabled,
and the now-useless loading action would continue. In stead we now
cancel any scheduled continuation, thaw the UI immediately, and switch
the menus and gameMode to ncp straight away.

Fix 50-move counter in ICS mode

Marking irreversible moves in the EP_STATUS did not work in ICS mode,
as ApplyMove,which did that is never executed there. Only the boards
sent by ICS are displayed,especially in observing mode. Now the status is
derived from the ICS mov strings (x in the SAN move, or P in the long move.

Fix piece symbols on switch back to variant normal

Variant switches were not properly detected, meaning the variable pieces
could keep a form belonging to a previous variant. (E.g. Queen remained
a Lance image after switching from shogi to normal.)

2012-02-26 14:07:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Keep XBoard windows attached on resize

Windows attached to bottom or right are displaced with the size increase.
Their perpendicular dimension is also scaled, to keep their edges at the same
fraction of the main window, unless they stick out. In the latter case the
fraction is clipped to 1, so that edge moves with the full size increase.

2012-02-25 22:40:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement -stickyWindows in XBoard

This makes the auxiliary windows  move with the main window when they were

2012-02-25 21:14:03 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use more reliable X-call for getting window position

XtGetValues on XtNx, XtNy is unreliable. XGetWindowAttributes seems
to give more reliable results, and automatically accounts for the width
of window dressing. The -frameX/Y options are no longer needed bcause
of this, and were removed.

2012-02-25 11:55:19 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make frame width configurable in XB

New persistent options -frameX, -frameY now can be used to specify
the amount by which Xt lies about the window coordinates.

2012-02-23 20:01:55 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use combobox line for recent engines when available

The entry made in the -recentEngineList for the startup engine was
derived from the -fcp value, but this would ignore a possible nickname.
In WinBoard we now use the full combobox line to derive the entry.

One missed translation of cps->which


2012-02-22 19:58:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Undo translation of cps->which = first/second

The string in cps->which should not be translated, because it goes into
the debug file to label engine I/O, and many tools for processing
debug files (broadcasters, PGN extractors) rely on this being "first" or
"second". In all contexts where "first" and "second" need to be translated,
cps->which itself is already enclosed in _().

2012-02-22 18:27:40 +0100 H.G. Muller <h.g.muller@hccnet.nl>:

to the clipboard.

2012-02-16 14:58:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Delete some load-game debug printing

The debug printing in Disambiguate was no longer needed. The printing
of the started process in XBoard that went to stderr is now diverted
to debugFP, so it ends up in the debug file.

2012-02-16 14:41:43 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Move change of debug file to before game load

Loading a game from -lgf is done before TwoMachinesEvent is called,
but logically belongs to the game. So the code to switch to the new
debug file for the game is moved to NextMatchGame now.

2012-02-16 14:09:54 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix button grab for sweep selection

The piece-menu initialization limited the grab of button events to those
occurring inside the board window (presumably intended to limit them to
the piece menu, but that does not pop up in sweep-selection mode).
This is now suppressed when -pieceMenu is off, so that selection continues
outside the the board. (Which is very convenient for pieces pu close to the
edge.)

2012-02-16 13:16:13 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Don't leave piece selected after piece menu

PieceMenuEvent left the just introduced piece selected, which is almost
never what one wants, as it makes it jump to the next square when selects.
Which is especially annoying if it captures the piece you wanted to grab...

Fix use of middle button for position setup

With sweep selection the actual drop is made on releasing the button,

Leave height of row that only contains buttons free

All elements of the GenericPopUp are still scaled to the text height,
including buttons appended behind them (browse or color buttons).
But we now make an exception for a row that only contains buttons,
as there is no harm in it being a little higher (and the buttons look
prettier that way).

Fix OK button of error popup

The error dialog popped up as a child of the board window, even when
DisplayError was called from a dialog. Now it checks if a transient

and suppresses the system popdown of the transient dialog through a flag
dialogError until it is popped down itself.

Fix switching animation masks on variant switch

The masks for variant-dependent piees (E,H in Seirawan, promoted Golds

Configure wider game list

The game list was by default too small, so that there was no room for the

Fix button chaining and combo/textbox label height

Previous patches forgot to specify the height for the text labels on
-combo and -text options, so they were still too high. Buttons that go

Fix popdown seekgraph on forward-event XB

Only the grid was drawn when the > or >> button were operated, because
a full redraw was not forced by ForwardInner. The recent patch to take
the seek graph down on such events did not account for that. (BackwardInner
always seems to do full redraw, however?)

2012-02-11 12:59:04 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put front-end support for -recentEngines in XBoard

The engines are added to the menu. Problem is still that in XBoard
startup engines are given by command, rather than selected by combobox,
so the command rather than the nickname ends up in the menu. If this is
then selected, it cannot be found in the list. To limit the damage,
Fairy-Max is now pre-installed without nickname. -recentEngines is now
configured to 4.

2012-02-11 11:53:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Better solution to button-height problem

In stead of adapting the height of text widgets to that of buttons,
(as represented by the message widget), we now do the opposite, and
adapt the button & label heights. This is made safe by obtaining textHeight
from the fontSet's max_logical_extent, though an XExtendsFontSet() call.
Turns out the default height of text widgets is not exactly that, but
4 pixels larger for borders and margin.
  The parameter XtNvertDistance is now used to align the checkboxes with
the following text widget, and their size is derived from textHeight as
well.
  The XtNvertDistance is set to -1 for the lower spin button, so that it
its border coincides with that of the upper spin button. Their height is
set to textHeight/2. This makes their combined height just 1 pixel more
than that of the preceeding text widget. (Uh? 2 x tw/2 -1 > tw?), so for
other buttons we use that too (i.e. textHeight = font_extent + 5).

Fix crash on empty combobox menu XB

XBoard crashed when a combobox without items was opened, as could easily

With the large height the widget get in internationalization, the
checkboxes are position way too high above the text. To shift them down

Derive height of text-edits in dialogs from message widget

Configure XBoard engines and textures

The new -useBoardTexture option is needed in xboard.conf, as we want to
distribute with the texture on, while the compiled-in default is off.
A list of 4 engines has been configured (fairymax, fruit, crafty, gnuchess),
as the Load Engine and Match Options checkboxes crash XBoard when the list
is empty. The -recentEngines option is set to 0 to make sure the code
associated with it is never executed: the code is still experimental,
and the required front-end support is only present in WinBoard anyway.

Fix arrow damage with highlightDragging XB

With highlight dragging the highlights of the previous moves are cleared
when lifting the piece. Logically, this should also clear the arrow, but
to do that requires a board redraw, which is not done at this stage. (And
even then this would only be effective after marking the arrow damage,
which is not done yet either). As a temporary fix, we repair the arrow
by redrawing it.
  This patch has moved marking of the arrow damage from DrawArrowHighlight
to a separate routine, so a future better fix can also call that when the
arrow should be erased.

2012-01-18 16:01:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Prevent unnecessary loading of engines

For engines that can be reused, the unloading at the end of a pairing
is in some cases wasteful, as the same engine will be used in the next
pairing as well. In simple gauntlets the gauntlet engine will always
stay first engine, while in multi-gauntlets the oppent engine will stay
the same for an entire round. In these cases unloading is now suppressed.

2012-01-17 22:22:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Reset protocol version before loading new engine

The protocol version was not reset, so if the previous engine was v1,
the newly loaded engine would not be sent a protover command, so
that its features would remain unknown!

2012-01-17 19:33:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Give focus to board window after ICS login

toprevent that the focus remains on any popped up chat boxes, it is
explicitlly set otherwise. The board window is preferred over the
ICS interaction window, because you can type from there to the ICS anyway,
and it makes all accelerator keys available.

2012-01-16 14:37:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix seek-graph popup and  popdown

Clicking outside the board area in WB (e.g.on the clocks) would also
trigger seek-graph 'popup'. This is now suppressed by testing for
y-coord > 0. In addition, the seek graph is automaticaly taken down
when we step to another position in the current game (using buttons,
arrow keys or whatever).

2012-01-15 21:29:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Suppress empty lines when observing on VICS

Capture of the engine kibitzes when observing an engine game with
-autoKibitz on was still leaking a linefeed on the Variant ICS
(but not FICS or ICC!?).

2012-01-15 21:24:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix printing non-numeric kibitz with -autoKibitz

Messages that were not considered kibitzed engine PV info for lack of
numeric content, were kibitzed as coming from "your opponent", which
is nonsense if you were iobserving, and masked the source. Fortunately
star_match[0] is still holding the original name, at that point.

Update texi file and remove duplicate control

Some missing option descriptions were added. The highlight-dragging
control was removed from the General Options dialog, as it did the same
as Show Target Squares. -highlightDragging wa changed to a volatile option
with default value true, making it effectively disappear as an XBoard
option. (In WinBoard it is still persistent.)

Implement -viewerOptions

A mechanism is added to allow the user to configure persistently if the
game viewer that starts on clicking PGN files will use -ncp mode, or
load an egine for analysis (or, in fact, do anything). This by introducing
a persistent string option -viewerOptions, which will be parsed as a
command line after the real command line when the option -viewer was present.

Fix WinBoard  clock-click bug

Clicking on the clock in WinBoard also called the LeftClick routine
for handling clicks on the board. This led to the from-square being set
to some inalid value, so that the next genuine board click was interpreted

or in EditPosition mode, where weird things are accepted.

2011-11-06 17:20:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add feature-override options

A few (dangerous) options are added to allow a user to override
engine features, or change their defaults, by supplying a string
with feature commands (e.g. "sigint=0") which tricks XBoard into
thinking the engine sent that. There is a -featureDefaults which is
processed before the engine features, and -first/secondFeatures
which is parsed just before engine initialization.
  This goes horribly wrong when the user wouldtry silly things like
including 'option' or 'done' features!

Clear board markers when moving to other position

Now the markers from -showTargetSquares would stay on after a first click
for the benefit of a click-click move, they would also stay on when not
finishing the move, but operating the < > buttons in stead to call up
other positions. ForwardInner and BackwardInner now clear the markers,

Speed up position search and consider side to move

The position search is made to pay attention to the side to move,

it drops below the number of pieces in the position we seek.

Fix duplicate loading of second engine in tourneys

To decide if new engines should be loaded, it was tested if first.pr
equalled NoProc, assuming that ReserveGame would have left the engine
loaded if the next game would need the same engines. But a reuse=0 engine
could have caused termination of the first engine process anyway, while
the second would still be alive. So unconditionally starting of the second
engine would cause redundant engine processes to abound.
  Now we only start new engine processes if both engine processes are dead.

Add option -discourageOwnBooks

This boolean option determines the default setting of the hasOwnBook

option is cleared, which would enable use of the GUI book, like the

on the engine install line can still overrule this, though.
 A control to set this option has been added in the XBoard Match dialog,
