OnImageDirtyChanged Method

Summary

Syntax

C++

protected virtual void OnImageDirtyChanged( 
   EventArgs e 
)

  
Protected Overridable Sub OnImageDirtyChanged( _ 
   ByVal e As EventArgs _ 
)

protected: 
virtual void OnImageDirtyChanged(  
   EventArgs^ e 
)

Parameters

e
An System.EventArgs that contains the event data.

Remarks

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

The ImageDirtyChanged event will be fired after the ImageDirty value changes.

The Leadtools.RasterImage in the Viewer changes after calling any of the following methods: RealizeRedaction, RestoreRedaction.

You can use this event along with the ImageDirty property to update your application user interface.

Example
