By default the button-press-event and the button-release-event signals are
filtered out for a widget. See:
https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget-button-press-event
You must enable their propagation in order to be able to handle them. Use
Set_Events for this purpose on the widget with the appropriate event mask.
