control size of a TGGroupFrame

Hello,

I have an object:
TGGroupFrame *fExtrema_min = new TGGroupFrame (fExtrema_f, "min", kVerticalFrame) ;

Then I fill it like:
fExtrema_min -> AddFrame (new TGLabel (fExtrema_min, new TGString (" Abscissa:")), new TGLayoutHints (kLHintsTop)) ;

But I cannot control the size of the Frame ! For example, like it is it is a lot too large.

My tries to resize fail

thank for your help
