As far as I can tell, NSCursor is Cocoa, so no good for my C
only code,
Any particular reason? You can compile your C code with the ObjC
compiler and thereby call ObjC APIs, and if your code really
isn't compatible with ObjC (say you use variables named "id"),
then you could just put the ObjC code into a separate source file.
Cross platform compatibility, historical reasons, and
simplicity. If I mix in any other language, it will be
C++ to be able to use WxWidgets, again for cross platform
compatibility.
OK, but keep in mind that Objective C is probably the most common
language being used today to provide new system services in Mac OS X.
It will become more and more difficult to build a fully savvy Mac OS
X application without using some Objective C-based APIs. It would
behoove all Mac OS X developers to become familiar with Objective C.
Sounds overly complicated for something so simple on other platforms,
but I assume this is more flexible.
Could you describe again exactly what you're trying to accomplish?
Maybe I've misunderstood your goals. You mentioned setting a custom
cursor per window, but you also mentioned wanting to hide the cursor.
I'm not quite sure how these intersect.
