OnBeforeDrawingObjects Method

Summary

Raises the BeforeDrawingObjects event.

Syntax

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

Parameters

e
An RasterCollection<AnnPaintEventArgs> that contains the event data.

Remarks

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

Example

For an example, refer to BeforeDrawingObjects.
