如何在Mac中使用Python获取活动的窗口标题? [英] How to get active window title using Python in Mac?

问题描述

我正在尝试编写Python脚本，该脚本在Mac OS中使用python打印活动窗口的标题.

I am trying to write the Python script which prints the title of the active window using python in Mac OS.

这是我的代码:

from AppKit import NSWorkspace
active_app_name = NSWorkspace.sharedWorkspace().frontmostApplication().localizedName()
print active_app_name

此代码仅显示应用程序的名称(例如Google chrome或firefox)，而不显示标题.如何获取窗口标题?

This code just prints name of the app like Google chrome or firefox, but not title. How to get title of the window?

推荐答案

这是我以前使用Quartz API在Mac OS X上使用Python查找活动应用程序名称和窗口标题的方法.

Here is what I used to find both the active application name and window title on Mac OS X using Python by using Quartz API.

首先，我们需要根据需要添加导入:

First of all, we need to add imports as required:

if sys.platform == "darwin":
    import applescript
    from AppKit import NSWorkspace
    from Quartz import (
        CGWindowListCopyWindowInfo,
        kCGWindowListOptionOnScreenOnly,
        kCGNullWindowID
    )

然后我们可以通过以下代码获取活动的应用程序名称和窗口标题:

And then we can get the active app name and window title via the code below:

def getActiveInfo(event_window_num):
    try:
        if sys.platform == "darwin":
            app = NSWorkspace.sharedWorkspace().frontmostApplication()
            active_app_name = app.localizedName()

            options = kCGWindowListOptionOnScreenOnly
            windowList = CGWindowListCopyWindowInfo(options, kCGNullWindowID)
            windowTitle = 'Unknown'
            for window in windowList:
                windowNumber = window['kCGWindowNumber']
                ownerName = window['kCGWindowOwnerName']
                # geometry = window['kCGWindowBounds']
                windowTitle = window.get('kCGWindowName', u'Unknown')
                if windowTitle and (
                                event_window_num == windowNumber
                        or ownerName == active_app_name
                ):
                    # log.debug(
                    #     'ownerName=%s, windowName=%s, x=%s, y=%s, '
                    #     'width=%s, height=%s'
                    #     % (window['kCGWindowOwnerName'],
                    #        window.get('kCGWindowName', u'Unknown'),
                    #        geometry['X'],
                    #        geometry['Y'],
                    #        geometry['Width'],
                    #        geometry['Height']))
                    break

            return _review_active_info(active_app_name, windowTitle)
        if sys.platform == "win32":
            (active_app_name, windowTitle) = _getActiveInfo_Win32()
            return _review_active_info(active_app_name, windowTitle)
    except:
        log.error('Unexpected error: %s' % sys.exc_info()[0])
        log.error('error line number: %s' % sys.exc_traceback.tb_lineno)
    return 'Unknown', 'Unknown'
