System_CAPS_pubpropertySource

Gets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)

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

FrameworkElement::ToolTipOpening

FrameworkElement::ToolTipClosing

FrameworkContentElement::ToolTipOpening

FrameworkContentElement::ToolTipClosing

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 ToolTipEventArgs class overrides the InvokeEventHandler method. However, this protected member does not appear on the ToolTipEventArgs list of members because the method is sealed and cannot be overridden in classes from ToolTipEventArgs. 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.

If the tooltip is defined as a ToolTip object, the Opened and Closed events of the ToolTip class are also raised when a tooltip opens and closes.
