Description
Contains drag-and-dock information for a control.
Vcl.Controls.TDragDockObjectEx inherits from Vcl.Controls.TDragDockObject. All content below this line refers to Vcl.Controls.TDragDockObject.
Contains drag-and-dock information for a control.
TDragDockObject is used in several events and methods that use drag-and-dock information, including the OnDockDrop and OnDockOver events of TWinControl.
Note: TDragDockObject is not automatically freed at the end of a drag-and-dock operation. To work with a drag object that is freed at the end of the drag-and-dock operation, use TDragDockObjectEx instead.
