Mac OS X supports three (or perhaps four or five) distinct GUI enviroments: Carbon, Cocoa, Java, and perhaps QuickTime and OpenGL. OpenGL => NSGL, AGL, CGL or GLUT (<http://developer.apple.com/qa/ qa2001/qa1269.html>) If I wanted to write a new GUI environment not layered on any of these, what would the appropriate API be? In other words, is it possible to write a GUI application without linking in anything but, say, Quartz or OpenGL (no Carbon, Cocoa, Java or QuickTime)? I understand that I would have to role everything myself, which is fine, because that's the point of the exercise. This isn't for end users, it's for me. I want to have a go at writing my own app framework that uses as little Apple code as possible on Mac OS X. Any help or ideas is appreciated. From what I can tell, the only supported way to create e.g. a window, is to use Carbon, Cocoa, or Java. I don't mind using SPI interfaces if need be; I just need to some pointers on what, exactly, I would need to interface with. Is is just the window server, or is there something else? To display windows and other standard widgets you will need to use some framework that has the concept of a window, Quartz and OpenGL don't have that directly themselves (at least not in the way you need). If you want to take over the whole the screen then you could just use OpenGL (CGL) and Quartz and do all your own drawing. This email sent to site_archiver@lists.apple.com
