Description
The TBaseDragControlObject object provides support for drag-and-drop or drag-and-dock operations.
Vcl.Controls.TDragDockObject inherits from Vcl.Controls.TBaseDragControlObject. All content below this line refers to Vcl.Controls.TBaseDragControlObject.
The TBaseDragControlObject object provides support for drag-and-drop or drag-and-dock operations.
Do not create instances of TBaseDragControlObject. TBaseDragControlObject, like its immediate ancestor TDragObject, handles operations common to both drag-and-drop and drag-and-dock behavior. TBaseDragControlObject adds support for associating a control with the drag object.
TBaseDragControlObject has two descendants: TDragControlObject, which is specialized for drag-and-drop operations, and TDragDockObject, which is specialized for drag-and-dock operations.
