AppleScript的 - 系统事件错误：辅助设备的访问被禁止 [英] AppleScript - System Events Error : Access for assistive devices is disabled

问题描述

我有一个AppleScript的和系统事件的一个问题。

I have a problem with AppleScript and System Events.

我必须勾选启用辅助设备的访问中的普及preference在系统preferences窗格。

I have check "Enable access for assistive devices" in the "Universal Access" preference pane in System Preferences.

当我尝试：

拱-i386 osascript -e'告诉应用程序系统事件让每一个过程的每一个窗口的位置

arch -i386 osascript -e 'tell application "System Events" to get the position of every window of every process'

我有这样的错误：

系统事件得到了一个错误：辅助设备的访问被禁止。 （-25211）

System Events got an error: Access for assistive devices is disabled. (-25211)

你有什么想法？

非常感谢

推荐答案

问题是不是辅助设备。 AppleScript的似乎错误地返回该错误code，当它试图访问一个过程，不能有任何的窗口窗口（在我的情况，这是谷歌浏览器助手）。

The problem is not the assistive devices. AppleScript seems to incorrectly return that error code when it tries to access windows of a process that can never have any windows (in my case it was "Google Chrome Helper").

您需要捕捉的错误。这对我的作品：

You need to catch the errors. This works for me:

tell application "System Events"
    set procs to processes
    set windowPositions to {}
    repeat with proc in procs
        try
            if exists (window 1 of proc) then
                repeat with w in windows of proc
                    copy w's position to the end of windowPositions
                end repeat
            end if
        end try -- ignore errors
    end repeat
end tell
return windowPositions

返回坐标对，如清单{{1067 22}，{31，466}，{27，56}，{63，22}，{987，22}} - 是什么你试图获得？

returning a list of coordinate pairs, such as {{1067, 22}, {31, 466}, {27, 56}, {63, 22}, {987, 22}} – is that what you were trying to get?
