Description
TCustomVirtualListAction provides items to client controls.
TCustomVirtualListAction represents the base class for the TVirtualListAction class.
TCustomVirtualListAction supplies items dynamically at run time to client controls such as list views, list boxes, or combo boxes. These items are supplied by the code you provide for an OnGetItem event handler.
Each item may include text, an image, and a pointer to data. Each client control determines which of these item's features it accepts.
When a TCustomVirtualListAction is added to an action manager, it uses the action to generate a drop-down list on a tool bar.
