popover在状态栏中时的NSPopover瞬态

问题描述

我在做一个应用程序，它居住在状态栏。点击状态项时，NSPopover弹出。

I'm making an app which lives in status bar. When status item is clicked, NSPopover pops up.

它看起来像这样：

这里是问题：我想要的是瞬态，也就是说，如果我点击popover之外的任何地方，它将关闭。

Here's the problem: I want it to be "transient", that is if I click anywhere outside of the popover, it will close. And while NSPopoverBehaviorTransient works fine when popover is in a window, it doesn't work when it's in status bar.

我自己如何实现这样的行为？

How can I implement such behavior myself?

推荐答案

原来很容易：

- (IBAction)openPopover:(id)sender
{
    // (open popover)

    if(popoverTransiencyMonitor == nil)
    {
        popoverTransiencyMonitor = [NSEvent addGlobalMonitorForEventsMatchingMask:NSLeftMouseDownMask|NSRightMouseDownMask handler:^(NSEvent* event)
                                    {
                                        [self closePopover:sender];
                                    }];
    }
}

- (IBAction)closePopover:(id)sender
{
    if(popoverTransiencyMonitor)
    {
        [NSEvent removeMonitor:popoverTransiencyMonitor];

        popoverTransiencyMonitor = nil;
    }

    // (close popover)
}

然而，不容易的是，有一个令人讨厌的问题与弹出的NSStatusItem popover弹出（当任务控制被调用或空间切换到一个全屏窗口时，它的行为不符合要求）。我不得不实现一个自定义窗口，它总是漂浮在NSStatusItem之上，并处理切换到一个全屏窗口等。这看起来很容易，但显然状态项目不是为这样的东西设计的）;

What wasn't easy, though, is that there are nasty issues with having a popover pop out of NSStatusItem (it didn't behave as desired when Mission Control was invoked or space switched to a full-screen window). I had to implement a custom window that always floats above the NSStatusItem and deals with switching to a full-screen window etc. It seemed easy, but clearly status items weren't designed for something like that ;)
