Have a member/variable of class TGGC, and FontStruct_t
member/variable:
FontStruct_t fFontStruct = gClient->GetFontByName(name);
TGGC* fGraphicsContext = new TGGC(TGLabel::GetDefaultGC());
fGraphicsContext->SetFont(gVirtualX->GetFontHandle(fFontStruct));
where name is the name of your font, like in the .rootrc file.
Use the TGGC object with the GUI CTOR. Remember to delete it when not
used anymore. AFAIK, the TGGC are _not_ adopted by the GUI classes.
Using your custom Graphics Context (TGGC) you can set all sorts of
things. Please refer to
http://root.cern.ch/root/html/TGGC.html
Also do a search on roottalk: Your question has been asked before!
Yours,
