API来获取其他应用程序的窗口/文档名称 [英] API to grab other application's window/document name

问题描述

在可可中有一个API，您可以在其中获取应用程序的窗口/文档名称？我已经有 [[NSWorkspace sharedWorkspace] launchedApplication] 来获取所有可用的应用程序，所以我可以访问包名称或进程ID。

Is there an API in cocoa in which you can grab an application's window/document name? I've already got [[NSWorkspace sharedWorkspace] launchedApplication] to fetch all available applications, so I've got access to the bundle name or process id. What should I look into so that I can get other application's window/document name.

推荐答案

你假设应用程序有一个只有一个窗口。这不是真的;一个应用程序可以有很多窗口。

You're assuming that the application has only one window. This is not true; an application can have many windows.

对于自己的应用程序，使用 [NSApp windows] 他们。具体来说，对于文档窗口，

For your own app, use [NSApp windows] to get an array of them. For document windows specifically, ask the document controller.

对于其他应用程式，请使用辅助功能或CGWindowList查看其窗口。没有简单的方法只要求文档窗口，因为并不是所有的应用程序都是基于文档的，并且并非所有基于文档的应用程序都基于NSDocument。

For other apps, use Accessibility or CGWindowList to look at their windows. There's no simple way to only ask for document windows, since not all apps are document-based and not all document-based apps are based on NSDocument.
