Leadtools.WinForms Namespace > RasterThumbnailBrowser Class : OnEnableKeyboardChanged Method |
'Usage Dim instance As RasterThumbnailBrowser Dim e As EventArgs instance.OnEnableKeyboardChanged(e)
protected: virtual void OnEnableKeyboardChanged( EventArgs^ e )
Raising an event invokes the event handler through a delegate.
The OnEnableKeyboardChanged 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 OnEnableKeyboardChanged in a derived class, be sure to call the base class's OnEnableKeyboardChanged method so that registered delegates receive the event.
This example overrides the virtual events of the RasterImageList class.
