Hide MAAttachedWindow when clicking outside

问题

I'm using an MAAttachedWindow to display a custom window under a NSStatusItem in the Menubar. Everything works fine, but I can't find an easy way to hide it when the user clicks outside of the window. I want to implement this behavior because it's what the user expects.

This is the code used to display the MAAttachedWindow:

- (void)toggleAttachedWindowAtPoint:(NSPoint)pt {
    if (!self.attachedWindow) {  
        self.attachedWindow = [[MAAttachedWindow alloc] initWithView:logView
              attachedToPoint:pt 
               inWindow:nil 
                 onSide:MAPositionBottom 
                atDistance:5.0];

  [self.attachedWindow setLevel:kCGMaximumWindowLevel];
 }

 if(isVisible)
  [self.attachedWindow makeKeyAndOrderFront:self];
 else
  [self.attachedWindow orderOut];
}

This code gets triggered by an NSStatusItem with a custom view which intercepts a click on it.

回答1:

You should be able to do this via the window's delegate method:

- (void)windowDidResignKey:(NSNotification *)notification

Set yourself as the window's delegate, and implement that to call through to your toggle method.

This is based on Carter Allen answer, but maybe will be helpfull to someone as i lost couple of hours trying to figure out the reason behind an EXEC_BAD_ACCESS, in short you can't release the attachedWindow inside his windowDidResignKey notification, so use autorelease:

- (void)windowDidResignKey:(NSNotification *)aNotification {
    NSLog(@"MainWinDelegate::windowDidResignKey: %@", [aNotification object]);

    if (fAttachedWindow && [aNotification object] == fAttachedWindow) {
        [window removeChildWindow:fAttachedWindow];
        [fAttachedWindow orderOut:self];
        [fAttachedWindow autorelease];
        fAttachedWindow = nil;
    }
}
