Changing the cursor in an NSTextView

votes

I'm hoping this will be a relatively easy thing to do.

I am writing a Mac app that will be (mostly) a giant NSTextView. I would like to override the default text position cursor to a unique color/shape cursor. I don't have a lot of Quartz or general drawing experience but that's something I can look into more on my own.

What I'm primarily looking for is advice on the best way to implement this. Is it going to be a matter of overriding the drawRect function, calling the super, and then implementing my own draw code?

How would I find the appropriate location to draw that cursor? Is it contained within the drawRect's passed rect?

Essentially, you'll have to subclass the NSTextView and override some methods. The obvious one is

-(void)drawInsertionPointInRect:(NSRect)aRect color:(NSColor *)aColor turnedOn:(BOOL)flag

but that doesn't seem to entirely take care of it. Apparently, you also have to override a private method:

-(void)_drawInsertionPointInRect:(NSRect)arg1 color:(NSColor *)color
