OnDragDelta Method

Summary

Raises the DragDelta event.

Syntax

C++

protected virtual void OnDragDelta( 
   InteractiveDragDeltaEventArgs e 
)

Protected Overridable Sub OnDragDelta( 
   ByVal e As InteractiveDragDeltaEventArgs 
)

protected:  
   virtual void OnDragDelta( 
      InteractiveDragDeltaEventArgs^ e 
   )

Parameters

Event data

Remarks

Raising an event invokes the event handler through a function. The OnDragDelta 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 OnDragDelta in a derived class, be sure to call the base class's OnDragDelta method so that registered delegates receive the event.
