OnInteractiveRegionRectangle Method
Summary
Raises the InteractiveRegionRectangle event.
Syntax
protected virtual void OnInteractiveRegionRectangle(Leadtools.Winforms.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.
