OnBeforeDrawingObjects Method
Summary
Raises the BeforeDrawingObjects event.
Syntax
protected virtual void OnBeforeDrawingObjects(Leadtools.Annotations.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.
