Hi,
A quick Carbon question:
How do I track the mouse in a custom HIView control?
So far, I'm handling the 'HitTest' event by setting the event part code param to '1' and returning noErr, after which I get a single 'Track' event.
However, I want to do something more like a scrollbar, that gets continuous mouse movement events and even handles the mouse moving 'outside' of the view.
Any ideas how to achieve this?
Do I have to go into a 'track the mouse' loop in the Track event or something? How do I redraw the control then? Does the event handler recurse?
Bye!
