procedure RemoveControl(Control: TControl);
virtual void __fastcall RemoveControl(TControl* Control) = 0 ;
Handles the undocking of a control from the associated container control.
The container control that uses the dock manager calls RemoveControl when one of its docked controls is undocked.
Control is the control that was just undocked.
RemoveControl performs any internal adjustments that are needed now that the control is no longer docked, forcing a repaint of the container control if necessary.
