Re: How to create NSCursor from CGBitmap?
Never mind I found it! I can create an NSBitmapImageRep using initWithCGImage:, create my NSImage using initWithSize:, and then add the representation to the image using addRepresentation:. Thanks anyway!

Create an NSBitmapImageRep from the bitmap (you may not even need to use a CGBitmap, if the bits are in a supported layout, you can simply wrap a NSBitmapImageRep around it directly) then add that rep to an NSImage, which you pass to NSCursor. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

How to create NSCursor from CGBitmap?
Hi all, I've got several .png files that I want to use as custom cursors in my app. I'm loading them into CGBitmap objects, and have written code that creates NSImage objects using them, via initWithCGImage:size:. I then use those NSImage objects to create my NSCursor objects via initWithImage:hotSpot:. Unfortunately, I just noticed that the NSImage function initWithCGImage:size: is not supported until OS X 10.6, and I need to support 10.5 as well. How can I create my NSCursor objects from my CGBitmap objects, in a manner that IS supported in 10.5? (By the way, I can't create the NSCursor objects directly from the files - assuming that's possible anyway - because I'm using cross-platform code to get my bitmaps, which provides an object that I can cast to a CGBitmap on the Mac. So, I need to start with CGBitmap objects and create NSCursor objects from those.)
