OnBeforeDrawingObjects Method

Summary

Syntax

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.
