Description

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 gtkWidgetAddEvents for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with GTK_NO_WINDOW widgets; to get events on those widgets, place them inside a GtkEventBox and receive events on the event box.
