cocoa - 无边框 NSWindow 上的圆角

Question

我正在创建一个应用程序和 I don't want a title bar :

If the title remains the same all the time, does it make sense to show it? For example, if an app doesn’t show the names of documents, or any other assets that it opens, and there is plenty of space at the top around other controls to grab onto if you want to move the window around, does the title serve much purpose?

问题是:我该怎么做？我尝试使用 [mainWindow setStyleMask:NSBorderlessWindowMask]; 但我无法使其具有圆角。我实在不知道怎么弄圆角。除此之外，我无法让它具有调整大小控件。如果我使用 [mainWindow setStyleMask:NSBorderlessWindowMask | NSResizableWindowMask]; 它不再是无边框的了。谁能帮我？谢谢。

虽然这是一个非常古老的问题......

现在在 OS X 10.11 上更容易了。

        window1.backgroundColor             =   NSColor.whiteColor()
        window1.opaque                      =   false
        window1.styleMask                   =   NSResizableWindowMask
                                            |   NSTitledWindowMask
                                            |   NSFullSizeContentViewWindowMask
        window1.movableByWindowBackground   =   true
        window1.titlebarAppearsTransparent  =   true
        window1.titleVisibility             =   .Hidden
        window1.showsToolbarButton          =   false
        window1.standardWindowButton(NSWindowButton.FullScreenButton)?.hidden   =   true
        window1.standardWindowButton(NSWindowButton.MiniaturizeButton)?.hidden  =   true
        window1.standardWindowButton(NSWindowButton.CloseButton)?.hidden        =   true
        window1.standardWindowButton(NSWindowButton.ZoomButton)?.hidden         =   true

        window1.setFrame(CGRect(x: 400, y: 0, width: 400, height: 500), display: true)
        window1.makeKeyAndOrderFront(self)
