objective-c - NSClosableWindowMask 对话框行为异常

Question

我有一个 Safari 浏览器插件，我想在其中打开一个 NSWindow 来显示版权说明。虽然对话框中的“确定”按钮关闭了对话框的窗口，并且运行良好，但当我单击左上角的红色关闭窗口“x”时，它也关闭了窗口，但它是父窗口(整个浏览器选项卡，我插件在运行)，仍然处于禁用状态，就好像模态窗口在某处打开一样。

我什至尝试将一个新的选择器附加到窗口关闭通知，它运行与确定按钮相同的代码，但仍然无法正常工作。

这是代码的相关部分:

- (void) closeBox
{
    // called when the Ok button pressed
    [NSApp abortModal];

}

- (void)closeClicked:(NSNotification *)notification
{
    // called when the close window 'x' button pressed
    NSLog(@"Closed");
    [NSApp abortModal];
}


- (void) openBox
{
    NSRect frame = NSMakeRect(0, 0, 300, 250);
     mwin  = [[[NSWindow alloc] initWithContentRect:frame
                                     styleMask:NSClosableWindowMask |NSTitledWindowMask
                                       backing:NSBackingStoreBuffered
                                         defer:NO] autorelease];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(closeClicked:)
                                             name:NSWindowWillCloseNotification
                                           object:mwin];
    NSButton * bn;
    bn = [[[NSButton alloc] initWithFrame:NSMakeRect(10, 10, 100, 20) ] autorelease];

    [bn setButtonType:NSMomentaryPushInButton];
    [bn setTitle:@"Ok"];
    [bn setTarget:self];
    [bn setAction:@selector(closeBox)];

    [[mwin contentView] addSubview:bn];

    [NSApp runModalForWindow:mwin];   
}

我已经修改了您的代码，尝试如下所示:-

- (void) closeBox
{
    // called when the Ok button pressed
  //Commented this line 
 // [NSApp abortModal];

    [mwin performClose:mwin];// Modified this line 


}

   //Modified below notification just comment the parameter
    - (void)closeClicked/*:(NSNotification *)notification*/
    {

    [NSApp abortModal];

}


- (void) openBox
{
    NSRect frame = NSMakeRect(0, 0, 300, 250);
    mwin  = [[[[NSWindow alloc] initWithContentRect:frame
                                         styleMask:NSClosableWindowMask |NSTitledWindowMask
                                           backing:NSBackingStoreBuffered
                                            defer:NO]retain]autorelease];
  //Modified notification below    

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(closeClicked)
                                                 name:NSWindowWillCloseNotification
                                               object:nil];
    NSButton * bn;
    bn = [[[NSButton alloc] initWithFrame:NSMakeRect(10, 10, 100, 20) ] autorelease];

    [bn setButtonType:NSMomentaryPushInButton];
    [bn setTitle:@"Ok"];
    [bn setTarget:self];
    [bn setAction:@selector(closeBox)];

    [[mwin contentView] addSubview:bn];

    [NSApp runModalForWindow:mwin];   
}
