Re: [gtkmm] Q: How to get button_press_event for Gtk::TreeView

["Kuth, Joachim Dr." <Joachim Kuth T_SYSTEM sysde eads net>]

Thanks to everyone for your support.

Daniel, you were right: the only thing I was missing was
the optional second argument to connect.

Now everything works as expected.


Summary:

--8<-------------------------------------------------
class CustomView : public Gtk::TreeView
{
   bool sig_button_pressed(GdkEventButton *ev);
};

bool CustomView::sig_button_pressed(GdkEventButton *ev)
{
   if (ev->type == GDK_BUTTON_PRESS && ev->button == 3) {
      std::cout << "Button 3 pressed" << std::endl;
	// pop up a menu here ...
      // and stop handling this event
      return true;
   } else {
      // ignored, have processing done by default handler
     return false;
   }
}
--8<-------------------------------------------------

and connect like this:

--8<-------------------------------------------------
CustomView m_tree_view;

m_tree_view.signal_button_press_event( ).connect(
       SigC::slot( *this, &CustomView::sig_button_pressed ), false ); 

--8<-------------------------------------------------


Thanks again,

Joachim Kuth.
