Hi Rutger,
a TGLabel has the following ctor:
TGLabel(const TGWindow *p, TGString *text,
GContext_t norm = fgDefaultGC,
FontStruct_t font = fgDefaultFontStruct,
UInt_t options = kChildFrame,
ULong_t back = fgDefaultFrameBackground);
to create the label with a loarge font do something like:
FontStruct_t font =
gClient->GetFontByName("-adobe-times-medium-r-*-*-24-*-*-*-*-*-iso8859-1");
new TGlabel(win, "aap", fgDefaultGC, font);
ROOT fonts are scaled to any size, so they sometimes don't look very nice
on the screen, but at least they show how the hardcopy will look like.
GUI fonts are not scaled. They are the size you give them in the GetFontByName()
call. That's why they always look nice.
Cheers, Fons.
