## Description

MouseLeave is a method used to perform actions when the mouse pointer leaves the client rectangle for the control. In TControl, it signals the OnMouseLeave event handler using the class instance as the Sender argument.

Descendent classes may override the method to perform actions needed for their implementations.

MouseLeave is called from the CMMouseLeave method when a CM_MOUSELEAVE message is handled for the control.
