Provides event information for events that occur when a tooltip opens or closes.
Assembly: PresentationFramework (in PresentationFramework.dll)
When a tooltip opens and closes, this class provides event information. The element that specifies the tooltip inherits from either FrameworkElement or ContentElement. Therefore, open and close events exist on both of these classes. The following table lists the events that use this class.
Events that occur when a tooltip opens
Events that occur when a tooltip closes
These events are registered by the ToolTipService class as the ToolTipOpeningEvent and ToolTipClosingEvent fields. The FrameworkElement and FrameworkContentElement classes both implement the ToolTipService and expose this event by defining the events in the previous table
The class overrides the InvokeEventHandler method. However, this protected member does not appear on the list of members because the method is sealed and cannot be overridden in classes from . The implementation of the method in this class casts the event handler delegate that is provided as a parameter to the method to the ToolTipEventHandler type.
