I think you solved my pb.
Actually, the thing to keep in mind before delete a widget is to not omit to
remove it from the group.
Your code works perfect on my machine.
I corrected my code (wich is just a test code) and
the "my_callback2" function now looks like this:
void my_callback2(Fl_Widget *w)
{
if(box)
{
remove(box);
Fl::delete_widget(box);
box = 0;
redraw();
}
}
It seems that it's no need to hide the widget before delete it.
The redraw function will do it.
Thanks again
