Widget.setEvents

Sets the event mask (see #GdkEventMask) for a widget. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget’s functionality, so be careful. This function must be called while a widget is unrealized. Consider [gtk.widget.Widget.addEvents] for widgets that are already realized, or if you want to preserve the existing event mask. This function can’t be used with widgets that have no window. (See [gtk.widget.Widget.getHasWindow]). To get events on those widgets, place them inside a #GtkEventBox and receive events on the event box.
