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