+
+When the tip window closes itself (which may happen at any moment and
+unexpectedly to the caller) it may {\tt NULL} out the pointer pointed to by 
+{\it windowPtr}. This is helpful to avoid dereferencing the tip window which
+had been already closed and deleted.

+
+By default, the tip window disappears when the user clicks the mouse or presses
+a keyboard key or if it loses focus in any other way - for example because the
+user switched to another application window.
+
+Additionally, if a non empty {\it rectBound} is provided, the tip window will
+also automatically close if the mouse leaves this area. This is useful to
+dismiss the tip mouse when the mouse leaves the object it is associated with.
