How to programmatically turn off the genie effect for a window using PyObjC?

Question

To speed up some unit tests that minimize and maximize windows, I want to turn off the genie effect for those windows on Mac OS X. I can get the wxPython window like this:

import AppKit
nsw = AppKit.NSWindow.alloc().initWithWindowRef_(window.MacGetTopLevelWindowRef())

How can I turn off the genie effect for nsw?

Answer 1

You cannot. There is no way to minimize a window on Mac OS X without the accompanying visual effect. (The minimization effect is performed by the Dock on the application's window, not by the application itself. Preventing the Dock from running just makes the application hang when it requests a window be minimized.)

You may be able to speed things up somewhat by setting the user's minimization effect to "Scale" (in the Dock pane of System Preferences), though.
