允许NSWindow(NSPanel)浮动在全屏应用程序上方 [英] Allow an NSWindow (NSPanel) to float above full screen apps

问题描述

我正在尝试添加一个小窗口，以从系统中的任何位置向主应用程序提供快速输入".

I'm trying to add a little window that provides "quick input" from any place in the system to the main app.

用户可以按下热键，然后弹出窗口，并在所有其他窗口上方浮动.

The user could hit a hotkey, the window pops up, and floats above all other windows.

在大多数情况下，这并不是什么大问题.我可以将NSWindow配置为:

For the most part, this isn't much of a problem. I can configure an NSWindow to be:

level = Int(CGWindowLevelKey.TornOffMenuWindowLevelKey.rawValue)
collectionBehavior = .CanJoinAllSpaces

我还可以将其设置为具有 NSNonactivatingPanelMask 选项的NSPanel.

I can also make it an NSPanel with NSNonactivatingPanelMask option set.

唯一的问题是:即使用户位于包含全屏应用程序的空间中，如何才能使窗口在屏幕上弹出?

我知道当应用程序为 LSUIElement = true (Dock中没有位置的应用程序)时，这是可能的，但我的不是.

I know this is possible when the app is LSUIElement=true (an app without a position in the Dock), but mine isn't.

推荐答案

好吧，我有一个正确的主意，棘手的部分是所有选项之间如何交互.这是有效的方法:

Okay, I had the right idea, the tricky part is how all the options interact with each other. Here's what works:

• NSPanel，不是 NSWindow
• 样式遮罩: [.borderless，.nonactivatingPanel]

• NSPanel, not NSWindow
• style mask: [.borderless, .nonactivatingPanel]

这些属性:

panel.level = .mainMenu
panel.collectionBehavior = [.canJoinAllSpaces, .fullScreenAuxiliary]

Swift 4.2代码

使用这些设置创建并显示面板.然后，您可以将面板拖到全屏应用程序(双显示器设置)上.

Create and show a panel using these settings. Then you can drag the panel onto a fullscreen app (dual monitor setup).

let panel2 = NSPanel(contentRect: NSRect(x: 0, y: 0, width: 200, height: 200), styleMask: [.titled, .nonactivatingPanel], backing: .buffered, defer: true)
panel2.level = .mainMenu
panel2.collectionBehavior = [.canJoinAllSpaces, .fullScreenAuxiliary]
panel2.orderFrontRegardless()

切换为无边界将阻止用户移动窗口.

Switching to borderless will prevent the user from moving your window.

let panel2 = NSPanel(contentRect: NSRect(x: 0, y: 0, width: 200, height: 200), styleMask: [.borderless, .nonactivatingPanel], backing: .buffered, defer: true)
panel2.level = .mainMenu
panel2.collectionBehavior = [.canJoinAllSpaces, .fullScreenAuxiliary]
panel2.orderFrontRegardless()
