Re: Problem with oversized twm titlebutton height

[John DelSignore]

Hi Frank, Thank you! That did it... I'm not sure I would have figured this out on my own! I had "LANG=en_US.UTF-8" set in my environment, which I picked up from the default Ubuntu login setup. If I run "env LANG=C twm" or "env LANG=en_US twm" the titlebuttons are scaled properly. Overcome by curiosity, I started twm under a debugger to see what it was doing with the fonts, and I found this comment in util.c: /*  * The following functions are sensible to 'use_fontset'.  * When 'use_fontset' is True,  *  - XFontSet-related internationalized functions are used  *     so as multibyte languages can be displayed.  * When 'use_fontset' is False,  *  - XFontStruct-related conventional functions are used  *     so as 8-bit characters can be displayed even when  *     locale is not set properly.  */ void GetFont(MyFont *font) { ... When "use_fontset" is true, the ascent and descent values are determined by the "max" ascent and descent of all the fonts in the set. For example, in the case I was looking at, the "fixed" font was an alias for 17 fonts, which included an "-arabic-newspaper-*" font that has an ascent==24 and descent==11. When "use_fontset" is false, twm does a straight-up by-name lookup of the font, which has an ascent==8 and descent==2. Finally, as you observed, the locale controls the setting of "use_fontset":     loc = setlocale(LC_ALL, "");     if (!loc || !strcmp(loc, "C") || !strcmp(loc, "POSIX") ||         !XSupportsLocale()) {          use_fontset = False;     } else {          use_fontset = True;     } Cheers, John D.

Below, I used the font "fixed" for the TitleFont, and the titlebutton is much bigger than height of the font. Why is that happening? Check your LC_CTYPE settings. When I use en_US.UTF-8 I get the same huge titlebuttons while en_US works fine. Maybe it somehow depends of the font you use, if it can handle utf8 encoding or not (just a guess). cu, Frank
