I'm developing an application for a company that is trying to brand itself with a particular font. They've given me all the .otf files for the fonts their other products use. Is it possible to set the font on widgets such as buttons and static texts to use these external files?
If so, would it be platform-independent? 
Thanks
Not yet, but it will probably be possible soon.  I saw a patch and discussion about it recently in the wxWidgets Trac.
