I am trying to re-implement Gtk::SpinButton using a container to start with. As part of the
re-implementation, I need to emulate the scrolling (a.k.a. spinning) functionality of the spin
entry. Is there any way I can make a Gtk::Button receive these special spin events? I
have this trivial piece of code below, but it doesn't do what I need. Anybody can please
point me in the right direction? (I suspect I'm doing something utterly silly here).
class SpinButton : public Gtk::Button {
public:
SpinButton() { add_events(Gdk::SCROLL_MASK); }
SpinButton(const std::string& lbl) : Gtk::Button(lbl) { add_events(Gdk::SCROLL_MASK); }
protected:
virtual bool on_scroll_event (GdkEventScroll* e)
{ std::cout << "This is never called" << std::endl; return Gtk::Button::on_scroll_event(e); }
};
Regards,
Nickolai
