[STR New]
I have attached a patch file that adds a margin property to PackedGroup.
It creates a constant spacing AROUND all the child Widgets in distinction
to the spacing BETWEEN the child widgets.
It gives a methods either to control left,right,top,button margins
separately, or all at once.
The patch is against fltk-2.0.x-r5777, but should apply to any recent
version.
Thanks,
Davy Durham
