OnDraw Method

Summary

Raises the Draw event.

Syntax

C#
VB
C++
protected virtual void OnDraw( 
   AnnDrawDesignerEventArgs e 
) 
  
Protected Overridable Sub OnDraw( _ 
   ByVal e As Leadtools.Annotations.AnnDrawDesignerEventArgs _ 
)  
protected: 
virtual void OnDraw(  
   Leadtools.Annotations.AnnDrawDesignerEventArgs^ e 
)  

Parameters

e
An AnnDrawDesignerEventArgs that contains the event data.

Remarks

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

Example

For an example, refer to AnnDesigner.
