Description

Occurs when the application tries to undock a control that is docked to the windowed control.

Write an OnUnDock event handler to adjust the windowed control when a dock client is undocked. The OnUnDock event handler can make any necessary adjustments, or it can block the undock attempt by setting the Allow parameter to false.

OnUnDock is an event handler of type Vcl.Controls.TUnDockEvent.
