Changing modeline color does not update 3d border

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta46) "Urania" [Lucid] (i586-pc-linux) of Sat Mar 24 2001 on c307652-b.stcla1.sfba.home.com configured using `configure --prefix=/local/xemacs' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: [Note: this is really a minor bug, probably not worth looking at until after April 15.] Execute: (set-specifier modeline-shadow-thickness 10) to see this effect more clearly. Execute: (set-face-background 'modeline "blue") Then ctrl-L to redraw the window. The modeline 3d border will be reddish. (set-face-background 'modeline "red") Now the modeline background will be blue. However the 3d border is still red! Execute: (redraw-modeline t) and the border is STILL red! I can use (redraw-frame) but that's icky, and flickers. I tried poking around the source (21.2b46) to figure out what's going on, but wasn't entirely successful. Things I found: frame-x.c has a comment /* Really crappy way to force the modeline shadows to be redrawn. But effective. */ redisplay-x.c has a comment /* Our flagging of when we need to redraw the modeline shadows sucks. */ window.c:window_modeline_height has a comment /* Bullshit alert. */ However I couldn't figure out what in the C code should be fixed to make modeline redrawing redraw the 3d border. I also couldn't figure out how to force a redisplay of the 3d border from elisp, except by changing the modeline-shadow-thickness to a different value, then changing it back (this bypasses the optimization "if it's the same value don't redisplay"). It's a silly workaround but that's what I'll use for now. - Amit Recent messages (most recent first): Loading emacsbug...done Loading emacsbug... color-focus:update Wrote /home/amitp/Emacs/color-focus.el color-focus:update A B C F I K L M N P S T V W C-c C-d C-f C-i C-k C-n C-w; ? for more help: Quit Auto-save off (in this buffer) Decoding modeline.el... done Decoding modeline.el...
