Hi all,
Apologies if this has been asked before; I've searched to
no avail.
After changing a window's label from a callback, how
can I make the change visible. No combination
of redraw_label(), redraw(), damage() or Fl::flush()
does the job. Nothing short of hide() followed by show()
seems to work.
TIA,
Stan
void cb(Fl_Widget*, void* v)
{
Fl_Double_Window* w = static_cast<Fl_Double_Window*>(v);
w->label("Changed it");
/// what now?
// w->hide(); w->show();
}
int main()
{
Fl_Double_Window win(300, 300, "A Window");
Fl_Button* btn = new Fl_Button(100, 100, 100, 30, "Try It");
win.end();
btn->callback(cb, &win);
win.show();
return Fl::run();
}
