问题描述

如何以编程方式更改Mac OS X中的桌面背景？我想使用python，但我对任何可能的方式感兴趣。我可以连接到终端并调用某个命令吗？

How would I go about programmatically changing the desktop background in Mac OS X? I'd like to use python, but I'm interested in any way possible. Could I hook up to Terminal and call a certain command?

推荐答案

从python中，如果你有 appscript （ sudo easy_install appscript ），你可以简单地做到

From python, if you have appscript installed (sudo easy_install appscript), you can simply do

from appscript import app, mactypes
app('Finder').desktop_picture.set(mactypes.File('/your/filename.jpg'))

否则，这个AppleScript将改变桌面背景

Otherwise, this applescript will change the desktop background

tell application "Finder"
    set desktop picture to POSIX file "/your/filename.jpg"
end tell

您可以使用 osascript ，或使用类似

You can run it from the command line using osascript, or from Python using something like

import subprocess

SCRIPT = """/usr/bin/osascript<<END
tell application "Finder"
set desktop picture to POSIX file "%s"
end tell
END"""

def set_desktop_background(filename):
    subprocess.Popen(SCRIPT%filename, shell=True)
