Notifies an OnUnDock handler and the DockManager of an undocked client control.

Declaration

Source position: controls.pp line 2253

protected function TWinControl.DoUnDock(

NewTarget: TWinControl;

Client: TControl;

KeepDockSiteSize: Boolean = True

):Boolean; virtual;

`NewTarget`		The new docksite, Nil for floating.
`Client`		The control being undocked.

Set to False to deny undocking.

The OnUnDock handler can deny the undocking request for the control. This can cause problems; instead, the control better should not be draggable.

TWinControl.DoUndockClientMsg		Notifies the DockManager of the undock of a client control.
TWinControl.OnUnDock		Event handler signalled before a control is undocked from its DockSite.
