我想伪造一个标题栏(更大,颜色不同),所以到目前为止我的方法如下:
我在标题栏的正下方添加了一个NSView,然后使用以下代码将标题栏设置为透明:
self.window.titlebarAppearsTransparent = true
self.window.styleMask |= NSFullSizeContentViewWindowMask
下一步是,我将NSView子类化为添加一些绘图方法(背景等),特别是代码,这样我就可以使用完整的NSView来移动窗口(因此我使用这段代码:{{3 }})
结果如下:
现在我要做的下一件事就是在这个新标题栏中垂直居中交通灯按钮。我知道,我可以使用self.window.standardWindowButton(NSWindowButton.CloseButton)
(例如)访问按钮。但是更改其中一个按钮的frame.origin
没有任何效果。
如何更改按钮的origin.y值?
更新
我发现,窗口调整大小会重新排列按钮。现在我决定将按钮作为子视图添加到我的假标题栏中,因为在标题栏中移动原点会切断按钮(显然它仅限于标题栏)。
这很有效,但奇怪的是按钮的鼠标悬停效果仍然保留在标题栏中。看看这个屏幕:
这实际上是我的代码:
func moveButtons() {
self.moveButtonDownFirst(self.window.standardWindowButton(NSWindowButton.CloseButton)!)
self.moveButtonDownFirst(self.window.standardWindowButton(NSWindowButton.MiniaturizeButton)!)
self.moveButtonDownFirst(self.window.standardWindowButton(NSWindowButton.ZoomButton)!)
}
func moveButtonDownFirst(button: NSView) {
button.setFrameOrigin(NSMakePoint(button.frame.origin.x, button.frame.origin.y+10.0))
self.fakeTitleBar.addSubview(button)
}

您需要添加工具栏并更改窗口属性titleVisibility
。这里有更多详细信息NSWindow Style Showcase。
let customToolbar = NSToolbar()
window?.titleVisibility = .hidden
window?.toolbar = customToolbar

Swift 4.2版本(无工具栏)。

普通屏幕。
全屏模式。

我的答案涉及@Vlad和@Lupurus的一些答案。要更改按钮位置,只需对NSWindow子类中的函数func moveButton(ofType type: NSWindow.ButtonType)
进行调用即可处理移动。
注意:就我而言,我只需要将按钮降低2像素即可。
要处理正常情况(不是全屏),我刚刚重写了NSWindow的功能func standardWindowButton(_ b: NSWindow.ButtonType) -> NSButton?
,以便在返回按钮之前根据需要移动按钮。
注意:更好的代码将具有一种单独的方法来计算新框架,并将新值存储在其他地方
要从全屏返回时正确处理动画,我们需要重写NSWindow的func layoutIfNeeded()
方法,从全屏返回的动画在需要时将调用此方法。
我们需要将更新的框架保存在NSWindow中。 nil值将触发帧重新计算。
您需要将更新的框架保留在NSWindow窗口中:
var closeButtonUpdatedFrame: NSRect?
var miniaturizeButtonUpdatedFrame: NSRect?
var zoomButtonUpdatedFrame: NSRect?
public override func layoutIfNeeded() {
super.layoutIfNeeded()
if closeButtonUpdatedFrame == nil {
moveButton(ofType: .closeButton)
}
if miniaturizeButtonUpdatedFrame == nil {
moveButton(ofType: .miniaturizeButton)
}
if zoomButtonUpdatedFrame == nil {
moveButton(ofType: .zoomButton)
}
}
override public func standardWindowButton(_ b: NSWindow.ButtonType) -> NSButton? {
switch b {
case .closeButton:
if closeButtonUpdatedFrame == nil {
moveButton(ofType: b)
}
case .miniaturizeButton:
if miniaturizeButtonUpdatedFrame == nil {
moveButton(ofType: b)
}
case .zoomButton:
if zoomButtonUpdatedFrame == nil {
moveButton(ofType: b)
}
default:
break
}
return super.standardWindowButton(b)
}
func moveButton(ofType type: NSWindow.ButtonType) {
guard let button = super.standardWindowButton(type) else {
return
}
switch type {
case .closeButton:
self.moveButtonDown(button: button)
closeButtonUpdatedFrame = button.frame
case .miniaturizeButton:
self.moveButtonDown(button: button)
miniaturizeButtonUpdatedFrame = button.frame
case .zoomButton:
self.moveButtonDown(button: button)
zoomButtonUpdatedFrame = button.frame
default:
break
}
}
func moveButtonDown(button: NSView) {
button.setFrameOrigin(NSMakePoint(button.frame.origin.x, button.frame.origin.y-2.0))
}
要处理全屏情况,我们需要在NSWindowDelegate中放置一些代码,在我的情况下,该委托是NSWindowController实例。此代码将强制func layoutIfNeeded()
方法从全屏显示时重新计算按钮帧:
public func windowWillExitFullScreen(_ notification: Notification) {
self.window.closeButtonUpdatedFrame = nil
self.window.miniaturizeButtonUpdatedFrame = nil
self.window.zoomButtonUpdatedFrame = nil
}
等等!
在我的测试中,此代码可以处理所有情况。
