Find the topmost window under a mouse cursor

[Alexander Scherbatiy]

Hello,

Does the Mac OS X contains a method that allows to find the topmost 
window under a mouse cursor?

There is the issue when a window is created under a mouse cursor or it 
is moved under a mouse cursor the system does not generate the 
NSMouseEntered event.

It is possible to synthetically generate the MouseEntered event for  
window creation and moving in Java because we need that a window 
behavior on Mac OS X was the same as on others platforms.
But it is necessary to have a way to know is this window the topmost 
under a mouse cursor.

Thanks,
Alexandr.
