Markus,
If your app is Leopard only, you better checkout:
NSTrackingArea at:
http://developer.apple.com/documentation/Cocoa/Conceptual/EventOverview/TrackingAreaObjec
ts/chapter_7_section_4.html#//apple_ref/doc/uid/10000060i-CH8-
DontLinkElementID_30
NSTrackingArea has methods to track the mouse moved events.

Hello List,
I have a WebView with a transparent overlay window + custom view
"attached" it to allow for custom overlay drawing on top of what the
WebView displays. This works very well.
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.
So I thought, I go through a WebView subclass, establishing the
tracking area there and forward the mouse messages to the overlay
window and its view manually. Unfortunately this doesn't work either
because the tracking area events are only firing if there is no
overlay.
The overlay view does get -mouseDown:, -mouseUp: and -mouseDragged:
events, but not -mouseMoved:. I'm pretty out of ideas, how can I get
-mouseMoved: messages on the overlay window?
Thanks for any input!
Regards
Markus
