I think I have found an unobtrusive way of changing the colour of a
Fl_Round_Button while use the gtk+ scheme.
I had to derive a new widget from Fl_Round_Button and override the draw()
method. The draw method then replaces the FL_SELECTION_COLOR value with the
value from selection_color(). After the widget is drawn, FL_SELECTION_COLOR
is then restored.
Here's the class I am using. So far I haven't noticed any adverse
side-effects.
Enjoy,
Alvin
