TDragManager.CaptureChanged procedure

Declaration

procedure CaptureChanged(OldCaptureControl: TControl); virtual
 ; abstract

Description

CaptureChanged is an abstract virtual method in TDragManager, and must be implemented in a descendent class. In the default drag manager implementation, the DragMode and DragKind properties for child controls are checked to determine if one of them has the mouse capture. If none of them are active, the Parent control calls DragStop.

CaptureChanged is called from the CaptureChanged method in TControl when the LM_CaptureChanged message is received by the control and the drag manager is active.
