当弹出窗口显示时，我很好奇是否可以在弹出窗口的窗口上设置基础设置，例如窗口级别.在我的测试中，弹出窗口似乎是一个窗口，但是它们不响应普通的NSWindow选择器，例如setLevel:.

When a popover shows, I'm curious whether it's possible to set the underlying settings on the popover's window, such as the window level. In my testing, popovers seem to be a window, but they doesn't respond to normal NSWindow selectors, such as setLevel:.

是否可以在NSPopover上设置窗口级别?

Is it possible to set the window level on a NSPopover?

推荐答案

NSPopover是NSObject的子类，而不是NSWindow的子类，因此不正式支持设置窗口级别.

NSPopover is a subclass of NSObject, not NSWindow, so setting the window level is not officially supported.

您可以尝试像这样获取窗口:

You could try getting the window like this:

NSWindow* popoverWindow = yourPopover.contentViewController.view.window;

我不知道您是否可以成功设置水平.

I have no idea whether you can then successfully set the level though.
