However, I can't figure out a way to get -mouseMoved: messages
on the overlay window's view. Tracking areas as well as
-mouseMoved: messages (with setting acceptsMouseMovedEvents:YES
on the overlay window) don't work because the overlay window is
borderless (NSBorderlessWindowMask) and transparent and the
framework does not send those messages to it.
Tracking rects in child windows is broken in Leopard. If you try
this under Tiger it will work consistently.
I've already filed a bug (5689076) and it's still marked as
Open." Feel free to file a duplicate.
One quirk of the bug is that if you hide the window (hide the
app or minimize the window), then reveal it again, the tracking
rects start working.
The workaround I developed for my application was to translate
the tracking rects to the coordinate system of the parent window
and attach the tracking rects to the parent window instead. The
parent window then receives the various mouseMoved: events and
passes them back to the child window for handling. A little
kludgy, but it works.
