Cocoa : Hide any window using accessibility

I am wondering how to hide/show any window (not belonging to my application) using accessibility. It should be Mac App Store compl开发者_JAVA百科iant (I already have a version using private function, but this is something I would like to stop).

Thanks in advance for your help,

You can't do that to a window using Accessibility. You can set the AXHidden of an AXApplication, or the AXMinimized of an AXWindow, but you can't simply hide (set AXHidden of) an AXWindow.
