Provides event information for events that occur when a tooltip opens or closes.
public ref class ToolTipEventArgs sealed : System::Windows::RoutedEventArgs
public sealed class ToolTipEventArgs : System.Windows.RoutedEventArgs
type ToolTipEventArgs = class inherit RoutedEventArgs
Public NotInheritable Class ToolTipEventArgs Inherits 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|
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.
Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.(Inherited from RoutedEventArgs)
Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.(Inherited from RoutedEventArgs)
Gets or sets a reference to the object that raised the event.(Inherited from RoutedEventArgs)
Determines whether the specified object is equal to the current object.(Inherited from Object)
Serves as the default hash function.(Inherited from Object)
Gets the Type of the current instance.(Inherited from Object)
When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation.(Inherited from RoutedEventArgs)
Creates a shallow copy of the current Object.(Inherited from Object)
When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.(Inherited from RoutedEventArgs)
Returns a string that represents the current object.(Inherited from Object)
