如何创建自定义模态NSWindow？ [英] How do I create a custom modal NSWindow?
问题描述
我想创建一个充当模式对话框的自定义NSWindow。通过自定义，我的意思是它在窗口中具有普通的用户控件，带有确定和取消按钮。该对话框将包含只读信息，并具有一些复选框，安全编辑字段等。
I want to create a custom NSWindow that acts as a modal dialog. By custom I mean it has normal user controls in the window, with a "OK" and "Cancel" buttons. The dialog will contain read only information, and have a few checkboxes, secure edit fields, etc.
MainMenu.xib文件将在启动时显示正常的Window，以及包括自定义的NSWindow（在启动时不可见）。
The MainMenu.xib file will have the normal Window visible at launch, plus include the custom NSWindow (which is NOT visible at launch).
我正在尝试查找示例代码以模态模式启动窗口（在应用程序初始化并启动main之后窗口），然后在确定上运行一个过程，并在该过程成功后隐藏对话框。否则，如果失败，请继续打开对话框，但在对话框上显示错误表。
I am trying to find example code to launch the window in modal mode (after the app initializes and launches main window), and on "OK" run a process, and on success of that process hide the dialog. Or on failure, keep the dialog up, but show an error sheet on the dialog.

推荐答案
您要查看 NSApplication 的 -runModalForWindow：和/或 -runModalSession：方法。请注意，使用模式窗口通常不是一个好主意，如果有可能避免这样做，则应该；也就是说，有时需要。
You want to look at NSApplication’s -runModalForWindow: and/or -runModalSession: methods. Note that using modal windows is generally a bad idea and if it’s at all possible to avoid doing so, you should; that said, sometimes needs must.
就启动一个流程，等待其完成等而言，您可以使用<$ c $来完成所需的工作。 c> NSTask ，尽管您没有提供足够的细节来确定。您可能想观察 NSTaskDidTerminateNotification 来告诉您任务何时完成。
As far as launching a process, waiting for it to finish and so on, you can probably do what you need with NSTask, although you don’t provide sufficient detail to be certain. You’d probably want to observe NSTaskDidTerminateNotification to tell you when the task had finished.
