OnDraw Method

Summary

Raises the Draw event.

Syntax

C++

protected virtual void OnDraw( 
   AnnDrawDesignerEventArgs e 
)

  
Protected Overridable Sub OnDraw( _ 
   ByVal e As Leadtools.Windows.Annotations.AnnDrawDesignerEventArgs _ 
)

protected: 
virtual void OnDraw(  
   Leadtools.Windows.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 C#/VB examples, refer to AnnDesigner.
