Method

GtkWidgetset_device_events

since: 3.0

Declaration [src]

void
gtk_widget_set_device_events (
  GtkWidget* widget,
  GdkDevice* device,
  GdkEventMask events
)

Description [src]

Sets the device event mask (see GdkEventMask) for a widget. The event mask determines which events a widget will receive from device. 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_add_device_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can’t be used with windowless widgets (which return FALSE from gtk_widget_get_has_window()); to get events on those widgets, place them inside a GtkEventBox and receive events on the event box.
