gtkmm x events are not working

I am trying to handle x events for a drawing area widget so the user can pan around and draw on it. Press event and release event handlers are called but not the motion notify event. I added Gdk::POINTER_MOTION_MASK and overrode on_motion_notify_event(GdkEventButton *event) handler but it doesn't get called. Am I doing something wrong?

If you did exactly what you stated, the problem is that you overloaded the right method name, but the wrong argument type. The correct overload is this (from the docs):

  virtual bool Gtk::Widget::on_motion_notify_event(GdkEventMotion * event)

Note the different argument type.
