OnInteractiveRegionRectangle Method

Summary

Raises the InteractiveRegionRectangle event.

Syntax

C++

protected virtual void OnInteractiveRegionRectangle( 
   RasterViewerRectangleEventArgs e 
)

  
Protected Overridable Sub OnInteractiveRegionRectangle( _ 
   ByVal e As Leadtools.Winforms.RasterViewerRectangleEventArgs _ 
)

protected: 
virtual void OnInteractiveRegionRectangle(  
   Leadtools.Winforms.RasterViewerRectangleEventArgs^ e 
)

Parameters

e
A RasterViewerRectangleEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnInteractiveRegionRectangle method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class. Notes to Inheritors: When overriding OnInteractiveRegionRectangle in a derived class, be sure to call the base class's OnInteractiveRegionRectangle method so that registered delegates receive the event.

Example

For an example, refer to IsInteractiveModeBusy.
