Description
TListControlAction is the base class for action objects that operate on the selection of a list control (list box or list view).
TListControlAction implements the common behavior for actions that work with list controls (list boxes and list views). Each descendant class performs a specific operation on the target list control. Do not use TListControlAction directly in an application. Instead, use a TListControlAction descendant such as TListControlSelectAll, TListControlClearSelection, TListControlDeleteSelection, TListControlCopySelection, or TListControlMoveSelection.
TListControlAction makes the target list control available to descendant classes as the value of the ListControl property. TListControlAction descendants then override the ExecuteTarget method to perform their specific function on the target list control.
