Hi,
FVWM is very good at using true type font. However, in order to find out the name of the font, it could be a game of guess and error.
The good thing is, gtk already has a gtkFontSelectDialog defined, which can display and give the font name that is selected.
The only thing left is to convert the name to fvwm font name and let fvwm change to the font dynamically.
I wrote a small c program that do the task.
It will write to $HOME/.fvwm/font.config like this:
#Bradley Hand ITC Bold 16
DefaultFont "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=16"
MenuStyle * Font "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=16"
*FvwmPager: Font "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=12"
*FvwmIconMan: Font "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=12"
*FvwmIconMan: TipsFont "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=12"
*FvwmScript: DefaultFont "Shadow=1 0 C:xft:Bradley Hand ITC:Bold:antialias=True:pixelsize=12"and in config, I simply “read font.config”.
This make sure next time when fvwm starts, it will use the selected fonts.
In order to dynamically change the fonts, I use a fvwmCommand module to receive commands. The commands are generated by the c program. It basically ask fvwm to read the font.config, restart FvwmPager and FvwmButtons.
The c code is here:
