Summary

Base implementation for the IJvDataItemRenderer interface.

run\JvDataProvider.pas


Pascal

 run\JvDataProvider.pas
 TJvBaseDataItemRenderer = class(TJvDataItemAggregatedObject, IJvDataItemRenderer);


Description

The TJvBaseDataItemRenderer class is the base implementation of the IJvDataItemRenderer interface. The class itself provides no implementation for interface's methods but rather declares them as abstract virtual methods.
As a descendant of TJvDataItemAggregatedObject it also provides access to the item object this extension belongs to (both as interface as well as the implementing object).
You should not instantiate an object of this class but rather one of it's descendants that override the methods for IJvDataItemRenderer.
