如何在Mac中使用Python获取活动窗口标题？

Question

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

这是我的代码:

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

此代码只打印应用程序的名称,如Google Chrome或firefox,但不打印标题.如何获得窗口的标题？

Answer 1

这是我使用 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时使用的内容。

首先，我们需要根据需要添加导入：

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

然后我们可以通过下面的代码获取活动的应用程序名称和窗口标题：

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'
