I tried this :
class MyGroup : public Fl_Group //Create a Fl_Group derived class
{
void MyGroup::draw()
{
Fl_Group::draw();
fl_push_clip(x(), y(), w() - Fl::box_dw(box()),
h() - Fl::box_dh(box()));
fl_pop_clip();
}
public:
MyGroup(int x, int y, int w, int h, const char *l=0)
: Fl_Group(x, y, w, h, l){}
};
class Application : public Fl_Double_Window
{
Fl_Box *bx; //Child box widget
MyGroup *grp;
public:
Application(int w, int h, const char *l, int argc, char *argv[]);
};
Application::Application(int w, int h, const char *l, int argc, char *argv[])
: Fl_Double_Window(w, h, l)
{
box(FL_DOWN_BOX); //Add 2 pixels borders all around the main window
color((Fl_Color) FL_WHITE);
begin();
grp = new MyGroup(Fl::box_dx(box()), Fl::box_dy(box()),
w - Fl::box_dw(box()), h - Fl::box_dh(box()));
bx = new Fl_Box(0,0,100, 400);
bx->box(FL_FLAT_BOX);
bx->color((Fl_Color) FL_RED);
grp->add(bx);
end();
resizable(this);
show(argc, argv);
}
int main (int argc, char ** argv)
{
Application myApp(500, 300, "My App", argc, argv);
return(Fl::run());
}
But infortunately pb remains the same.
May be a tip in the virtual draw function ?
