重新显示窗口后未调用 NSWindow windowDidResignKey

我有一个自定义 NSWindow 子类，用户可以通过单击按钮来切换其显示。我还希望当窗口放弃关键状态时窗口消失（例如，通过用户在窗口外部单击）。

我有一个实现 windowDidResignKey: 的委托，但我发现该委托方法仅在窗口第一次退出键时被调用。

以下是我切换窗口显示的方法（通过用户操作或 windowDidResignKey）：

- (void) toggleWindowAtPoint:(NSPoint)point
{
    // Attach/detach window.
    if (!attachedWindow) 
    {
        attachedWindow = [[CustomWindow alloc] attachedToPoint:point];
        attachedWindow.delegate = self;
        [attachedWindow setLevel:NSMainMenuWindowLevel+1];  // show window in front of all other apps on desktop
        [attachedWindow makeKeyAndOrderFront:self];
    } 
    else 
    {
        attachedWindow.delegate = nil;
        [attachedWindow orderOut:self];
        [attachedWindow release];
        attachedWindow = nil;
    }    
}

这是我对 windowDidResignKey 的实现：

- (void) windowDidResignKey:(NSNotification *)note
{
    [self toggleWindowAtPoint:NSMakePoint(0, 0)];
}

我发现第一次显示自定义窗口时，会调用 windowDidResignKey: 。此后每次重新显示自定义窗口时，都不会调用 windowDidResignKey:。

I have a custom NSWindow subclass that the user can toggle the display of with the click of a button. I'd also like the window to disappear when the window resigns key status (e.g. by the user clicking outside the window).

I have a delegate that implements windowDidResignKey: but I find that this delegate method is only invoked the first time the window resigns key.

Here's how I toggle the display of the window (via user action or windowDidResignKey):

- (void) toggleWindowAtPoint:(NSPoint)point
{
    // Attach/detach window.
    if (!attachedWindow) 
    {
        attachedWindow = [[CustomWindow alloc] attachedToPoint:point];
        attachedWindow.delegate = self;
        [attachedWindow setLevel:NSMainMenuWindowLevel+1];  // show window in front of all other apps on desktop
        [attachedWindow makeKeyAndOrderFront:self];
    } 
    else 
    {
        attachedWindow.delegate = nil;
        [attachedWindow orderOut:self];
        [attachedWindow release];
        attachedWindow = nil;
    }    
}

Here's my implementation of windowDidResignKey:

- (void) windowDidResignKey:(NSNotification *)note
{
    [self toggleWindowAtPoint:NSMakePoint(0, 0)];
}

I'm finding that the first time the custom window is displayed, windowDidResignKey: gets called. Every time the custom window is re-displayed after that, windowDidResignKey: is not getting invoked.

问题是，在某些情况下，调用 [attachedWindow makeKeyAndOrderFront:self] 后，自定义窗口实际上并未成为关键窗口。

我通过在重新创建窗口之前添加以下行来修复此问题：

[[NSApplication sharedApplication] activateIgnoringOtherApps:YES];

在上面的代码片段的上下文中：

- (void) toggleWindowAtPoint:(NSPoint)point
{
   // Attach/detach window.
   if (!attachedWindow) 
   {
      [[NSApplication sharedApplication] activateIgnoringOtherApps:YES];
      attachedWindow = [[CustomWindow alloc] attachedToPoint:point];
      ....

The issue was that in some cases, the custom window was not actually becoming the key window after calling [attachedWindow makeKeyAndOrderFront:self].

I fixed this by adding the following line before re-creating the window:

[[NSApplication sharedApplication] activateIgnoringOtherApps:YES];

In the context of the code snippet above:

- (void) toggleWindowAtPoint:(NSPoint)point
{
   // Attach/detach window.
   if (!attachedWindow) 
   {
      [[NSApplication sharedApplication] activateIgnoringOtherApps:YES];
      attachedWindow = [[CustomWindow alloc] attachedToPoint:point];
      ....

您是否尝试过在切换方法中调用 [attachedWindow makeFirstResponder:attachedWindow] ？

如果您想在不使用 activateIgnoringOtherApps: 的情况下激活窗口，您应该使用带有 NSNonactivatingPanelMask 的 NSPanel：

[[CustomPanel alloc] 
        initWithContentRect: NSZeroRect 
                  styleMask: NSNonactivatingPanelMask 
                    backing: NSBackingStoreBuffered 
                      defer: NO];

If you want to activate a window without using activateIgnoringOtherApps: you should use a NSPanel with a NSNonactivatingPanelMask:

[[CustomPanel alloc] 
        initWithContentRect: NSZeroRect 
                  styleMask: NSNonactivatingPanelMask 
                    backing: NSBackingStoreBuffered 
                      defer: NO];
