how do i get ComponentMoved notification only at the end of drag?

I have a bunch of JInternalFrames inside a JFrame.

I register with these internal frames as a component listener, so i can
detect when they move.

when a user clicks-and-drags to move an internal frame, i my listener
gets called a bunch of times during the drag. i really only want one
call, when the user releases the mouse at the end of the move, and a
not a bunch of calls every time the user moves the mouse in between the
start and the end of the drag.

how do i do this?

I guess you could set your own DesktopManager. Delegate to the old
manager. Subclassing DefaultDesktopManager is not a good idea because
subclassing is generally not a great move, and I believe PL&Fs tend to
provide there own implementation.
