如何在 NSStatusBar 中绘制自定义视图?

How to draw custom view in NSStatusBar?

我目前有一个 NSStatusBar 和一个显示标题的 NSStatusBarItem。但我不想用自定义 NSView 替换 title/text。我该怎么做?

我目前有:

func applicationDidFinishLaunching(_ aNotification: Notification) {
    let statusBar = NSStatusBar.system
    statusBarItem = statusBar.statusItem(withLength: NSStatusItem.variableLength)
    statusBarItem.button?.title = "My Menu Bar App"
}

假设我不想用以下内容替换标题:

let view = NSView(frame: NSRect(x: 0, y: 0, width: 40, height: 40))
view.layer?.backgroundColor = NSColor.yellow.cgColor

我怎样才能做到这一点?我试图将它作为子视图添加到按钮,但没有成功。

  • 创建对 class

    顶层状态项的强引用
    let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
    
  • applicationDidFinishLaunching中启用图层并将视图添加到按钮的子视图中

    func applicationDidFinishLaunching(_ aNotification: Notification) {
    
        let view = NSView(frame: NSRect(x: 0, y: 0, width: 22, height: 22))
        view.wantsLayer = true
        view.layer?.backgroundColor = NSColor.yellow.cgColor
        statusItem.button?.addSubview(view)
    
    }
