Borderlessウィンドウで閉じるを有効にする

Posted at

問題

カスタムウィンドウを作る時NSBorderlessWindowMaskを指定すると、デフォルトのウィンドウを閉じる機能が無効化されてしまい、メニューから閉じたり、cmd+wで閉じたりすることができなくなる。

解決法

カスタムウィンドウクラスでvalidateMenuItemをオーバーライドしてperformCloseを有効化させ、performCloseをオーバーライドして閉じる処理を記述する。

class MyWindow: NSWindow {

...

    override func performClose(sender: AnyObject?) {
        // 処理

        ...

        self.close()
    }
    
    override func validateMenuItem(menuItem: NSMenuItem) -> Bool {
        return menuItem.action == #selector(performClose(_:)) ? true : super.validateMenuItem(menuItem)
    }

...
