Re: cursors in windows

Is there an easy way to have a cursor change when it is in a specific window? Up until now I have been using window regions and PtnInRgn() to determine which cursor to display. That means I have to add and subtract from the regions as various windows appear, disappear, and move around. And now I am having a strange problem where I go to move a window, and the cursor changes to the wrong thing as the window is being moved. Somewhere my window region calculation is getting screwed up.

Take a look at the kEventWindowCursorChange event in CarbonEvents.h (available in Mac OS X and CarbonLib 1.5 and later). I would say this would be the preferred method to use.

I currently handle cursor adjusting in my windows based on mouse-moved events. I didn't adopt the better method(s) since my baseline is CarbonLib 1.2. In this approach, just install a mouse-moved handler on your window. When your handler is called, you can get the mouse position and adjust the cursor as needed.
