How to get Window reference (CGWindow, NSWindow or WindowRef) from CGWindowID in Swift?

How to get Window reference (CGWindow, NSWindow or WindowRef) from CGWindowID in Swift on XCode 7.3 Mac Playground?

I referenced from Apple's document - Window Manager Reference, and from the sample code SonofGrab, but I didn't find an answer in obj-C nor Swift.

How should I do it?

回答1:

This should work for NSWindow from CGWindowID

NSWindow * ns_window;
ns_window = [NSApp windowWithWindowNumber: windowNumber];

To get CGWindowID from NSWindow use

CGWindowID window_id = (CGWindowID)[ns_window windowNumber];
