Hi Andreas,
it is not very nice (mix of GC and fontstruct) but this is the way to
solve your problem:
change the *** new *** part to:
FontStruct_t myfont =
gClient->GetFontByName("-adobe-helvetica-bold-r-*-*-12-*-*-*-*-*-iso8859-1");
TGGC* myGC = new TGGC(TGLabel::GetDefaultGC());
myGC->SetFont(gVirtualX->GetFontHandle(myfont));
and change the label creation to:
fLabel[i] = new TGLabel(fF[i], numlabel[i], myGC->GetGC(), myfont);
the problem is that the label size calculation is done using the myfont
FontStruct_t without looking into the GC if the font was specified
there, so they need to be specified both. Will be streamlined in the
future but the above recipe should always work.
Cheers, Fons.
