获得WindowRef的界限？

Question

我试图找到一个Carbon API,它可以从窗口id给我WindowRef,并且我想要有windowref的界面？

编辑:我发现API extern WindowRef HIWindowFromCGWindowID(CGWindowID inWindowID); 但我无法使用它.我已经包含了碳标头,并且还将其框架添加到项目中.HI apis还需要其他东西吗？

任何帮助表示赞赏.感谢您的时间.

以下应该做 -

        CGRect rect;
        uint32_t windowid[1] = {windowID};
        CFArrayRef windowArray = CFArrayCreate ( NULL, (const void **)windowid, 1 ,NULL);
        CFArrayRef windowsdescription = CGWindowListCreateDescriptionFromArray(windowArray);
        CFDictionaryRef windowdescription = (CFDictionaryRef)CFArrayGetValueAtIndex ((CFArrayRef)windowsdescription, 0);
        if(CFDictionaryContainsKey(windowdescription, kCGWindowBounds))
        {
            CFDictionaryRef bounds = (CFDictionaryRef)CFDictionaryGetValue (windowdescription, kCGWindowBounds);
            if(bounds)
            {
                CGRectMakeWithDictionaryRepresentation(bounds, &rect);
            }
        }
        CFRelease(windowArray);
