From: Tim Mann Date: Sun, 29 May 2011 04:07:08 +0000 (-0700) Subject: Fix display of international characters outside the ASCII range. X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=28c8627bf447437dc772045aec1ce7c0d18b7d5a;p=xboard.git Fix display of international characters outside the ASCII range. 1) Set Xaw resources required for internationalization -- *international and *fontSet. 2) Untangle the new XFontSet-aware code from the old FindFont code. It doesn't make any sense to apply the old (and obsolete) size searching code from FindFont to a font set, which contains fonts that are all the requested size. 3) With these changes, the -font option doesn't work at all when given on the command line. The -font option actually is parsed by the Xt library, used to set the *font resource, and removed from argv before xboard can see it, so the option didn't really work properly with the new WinBoard-style option framework anyway. Now that -font is even more broken, I changed the documented name of the option to -messageFont and changed args.h so the option is saved in ~/.xboard as -messageFont. --- diff --git a/args.h b/args.h index 2d1e8c3..faaf63f 100644 --- a/args.h +++ b/args.h @@ -316,8 +316,8 @@ ArgDescriptor argDescriptors[] = { { "popUpErrors", ArgBoolean, (void *) &appData.popupMoveErrors, FALSE, INVALID }, /* only so that old WinBoard.ini files from betas can be read */ { "clockFont", ArgFont, (void *) CLOCK_FONT, TRUE, INVALID }, - { "messageFont", ArgFont, (void *) MESSAGE_FONT, !XBOARD, INVALID }, - { "font", ArgFont, (void *) MESSAGE_FONT, XBOARD, INVALID }, + { "messageFont", ArgFont, (void *) MESSAGE_FONT, TRUE, INVALID }, + { "font", ArgFont, (void *) MESSAGE_FONT, FALSE, INVALID }, /* only so that old .xboardrc files will parse. -font does not work from the command line because it is captured by the X libraries. */ { "coordFont", ArgFont, (void *) COORD_FONT, TRUE, INVALID }, { "tagsFont", ArgFont, (void *) EDITTAGS_FONT, TRUE, INVALID }, { "commentFont", ArgFont, (void *) COMMENT_FONT, TRUE, INVALID }, diff --git a/xboard.c b/xboard.c index 72c24da..f9fe68f 100644 --- a/xboard.c +++ b/xboard.c @@ -251,7 +251,12 @@ void CreatePieces P((void));
