OnKeyDown Method

Summary

Raises the KeyDown event.

Syntax

C++

protected virtual void OnKeyDown( 
   InteractiveKeyEventArgs e 
)

Protected Overridable Sub OnKeyDown( 
   ByVal e As InteractiveKeyEventArgs 
)

protected:  
   virtual void OnKeyDown( 
      InteractiveKeyEventArgs^ e 
   )

Parameters

Event data

Remarks

Raising an event invokes the event handler through a function. The OnKeyDown method also allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.

**Note to Inheritors: **When overriding OnKeyDown in a derived class, be sure to call the base class's OnKeyDown method so that registered delegates receive the event.
