procedure DoRemoveDockClient(Client: TControl); dynamic;
DYNAMIC void __fastcall DoRemoveDockClient(TControl* Client);
Responds when a control is undocked from the windowed control.
DoRemoveDockClient is called automatically when a client control is undocked from the windowed control. As implemented in TWinControl, DoRemoveDockClient does nothing.
Client is the control that has been undocked.
Override DoRemoveDockClient to perform any necessary adjustments when a control is undocked from the windowed control.
Note: DoRemoveDockClient occurs at the end of the undocking process. To make changes when undocking starts, override the DoUnDock method instead.
