Description
TCustomListAction is the base class for action objects that provide items to client controls.
TCustomListAction implements the common behavior for actions that supply the items to a list view, list box or combo box.
When an application sets the Active property of a list action to true, the action fills all client list boxes and combo boxes with items. Each item may include information such as a text caption, an image, and a pointer to data.
When the user selects an item in one of the client controls, the client "executes" the list action, which causes it to generate an OnItemSelected event.
When a TCustomListAction is added to an action manager, it uses the action to generate a drop-down list on a tool bar.
