gtk:widget-has-tooltip (object)

object -- a gtk:widget object
setting -- a boolean whether the emission of the "query-toolip" signal is enabled or disabled

Accessor of the has-tooltip slot of the gtk:widget class. Enables or disables the emission of the "query-tooltip" signal on the widget. A true value indicates that the widget can have a tooltip, in this case the widget will be queried using the "query-tooltip" signal to determine whether it will provide a tooltip or not. Note that setting this property to true for the first time will change the event masks of the gdk:window objects of this widget to include "leave-notify" and "motion-notify" events. This cannot and will not be undone when the property is set to false again.
