Hi Markus,
I ran into exactly the same problem; my view was in a transparent,
borderless, and nonactivating panel. It didn't get mouse moved
events, and tracking rectangles didn't work either. (My problem was
that I wanted to change the cursor when it was inside my view, but it
never worked).
I eventually concluded that "Cocoa doesn't expect you to be interested
in mouse moved events or setting the cursor for a window that's not
active" and gave up. I suspected at the time that it was the
"nonactivating" property of the panel that was causing the issue.
If you get any further, I'd be keen to hear what you find out.
Cheers,
Brett

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
