Syntax

protected virtual void OnInteractiveRegionRectangle( 
   RasterViewerRectangleEventArgs e
)

'Declaration
 
Protected Overridable Sub OnInteractiveRegionRectangle( _
   ByVal e As RasterViewerRectangleEventArgs _
)

'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerRectangleEventArgs
 
instance.OnInteractiveRegionRectangle(e)

protected virtual void OnInteractiveRegionRectangle( 
   RasterViewerRectangleEventArgs e
)

 function Leadtools.WinForms.RasterImageViewer.OnInteractiveRegionRectangle( 
   e 
)

protected:
virtual void OnInteractiveRegionRectangle( 
   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.
