Mac OS X linker error in Qt; CoreGraphics & CGWindowListCreate

Here is my .mm file

#inclu开发者_JAVA技巧de "windowmanagerutils.h"

    return QRect();

The linker is telling me "_CGWindowListCreate" is undefined. What libraries must I link to? Apple's documentation is not very helpful on telling what to include or link to, like MSDN is. Also I couldn't just do #import <CGWindow.h>, I had to specify the absolute path to it... any way around that?

The CGWindowListCreate function is part of the Quartz Window Services. The corresponding framework is ApplicationServices which is located under /System/Library/Frameworks/.

So, you can just include <ApplicationServices/ApplicationServices.h> at the top of the file and link with the -framework ApplicationServicesoption.
