   ByVal e As AnnDrawDesignerEventArgs _
)

'Usage
 
Dim instance As AnnDrawDesigner
Dim e As AnnDrawDesignerEventArgs
 
instance.OnDraw(e)

protected virtual void OnDraw( 
   AnnDrawDesignerEventArgs e
)

 function Leadtools.Annotations.AnnDrawDesigner.OnDraw( 
   e 
)

virtual void OnDraw( 
   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.
