FindLCLWindow is a TWinControl function used to find the window (and its owner control) at the specified screen coordinates.

FindLCLWindow gets the Handle for the window and checks to ensure it is enabled. When it is not enabled, or AllowDisabled is False, parent handles are examined until a suitable window is located. FindOwnerControl is called for the handle to get the return value. The return value is Nil if a Window was not found at the specified position.
