onForeCanvasSizeChanged Method

Summary

Raises the ForeCanvasSizeChanged event.

Syntax
TypeScript
JavaScript
ImageViewer.prototype.onForeCanvasSizeChanged = function( 
   e 
) 
onForeCanvasSizeChanged( 
   e: LeadEventArgs 
): void; // protected

Parameters

e

Event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnForeCanvasSizeChanged 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.

Note to Inheritors: When overriding OnForeCanvasSizeChanged in a derived class, be sure to call the base class's OnForeCanvasSizeChanged method so that registered delegates receive the event.
