OnInteractiveUserRectangle Method
Summary
Raises the InteractiveUserRectangle event.
Syntax
protected virtual void OnInteractiveUserRectangle(Leadtools.Windows.Controls.RectangleInteractiveEventArgs e)
Protected Overridable Sub OnInteractiveUserRectangle( _ByVal e As Leadtools.Windows.Controls.RectangleInteractiveEventArgs _)
protected:virtual void OnInteractiveUserRectangle(Leadtools.Windows.Controls.RectangleInteractiveEventArgs^ e)
Parameters
e
A RectangleInteractiveEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.
The OnInteractiveUserRectangle 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 OnInteractiveUserRectangle in a derived class, be sure to call the base class's OnInteractiveUserRectangle method so that registered delegates receive the event.
