Re: [gtk-list] GdkFonts (or rather, fonts in X)

Hi Derek. The GtkExtra libraries includes a package called gtkpsfont.
Basically it allows you to render the 35 standard ps fonts as gdk fonts
and viceversa. It's kinda WYSYWYG, and gdk fonts are chosen to reproduce
the PS fonts look. The idea was borrowed from DiaCanvas and XFig, and it
works very well, as you can see in GtkPlot, and the postscript output. It
also allows you to add your
custom defined fonts in pairs (gdkfont, psfont). You have also the widget
GtkFontCombo that works exactly as the font combo in the commercial
applications, with combos to select the family and the size, and buttons
to select bold and italics. It's a toolbar subclass and you can add
more functions if you like, as underline button, justification, etc.
Take a look at testgtkfontcombo in the distribution. 
Hope this helps,
