TouchEventArgs::InvokeEventHandler Method (Delegate^, Object^)

.NET Framework (current version)
 

Invokes event handlers in a type-specific way, which can increase event system efficiency.

Namespace:   System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

protected:
virtual void InvokeEventHandler(
	Delegate^ genericHandler,
	Object^ genericTarget
) override

Parameters

genericHandler
Type: System::Delegate^

The generic handler to call in a type-specific way.

genericTarget
Type: System::Object^

The target on which to call the handler.

This implementation casts the generic handler as an EventHandler<TEventArgs> of type TouchEventArgs and then invokes it. For more information about this implementation pattern and the reasons for it, see InvokeEventHandler and Routed Events Overview.
