Swift：获取带有桌面号码和位置信息的打开应用窗口列表

Question

我正在开发一个可以与应用Windows一起使用的MacOS应用程序。 我现在负担不起的目标是检索所有打开的应用程序窗口的列表，看起来像这样（JSON示例）：

[
  {
    "appName": "Google Chrome",
    "appWindows": [
      {
        "size": {"x": 100, "y": 100}, 
        "position": {"height": 100, "width": 100}, 
        "desktopNumber": 2
      },
      {
        "size": {"x": 100, "y": 100}, 
        "position": {"height": 100, "width": 100}, 
        "desktopNumber": 3
      }
    ]
  },
  {
    "appName": "Telegram",
    "appWindows": [
      {
        // full screen app, so has a separate desktop number
        "size": {"x": 1080, "y": 1920}, 
        "position": {"height": 0, "width": 0}, 
        "desktopNumber": 4
      }
    ]
  }
]

每个应用程序都有一系列打开的窗口，并在桌面号码旁边打开。一个全尺寸的应用程序包含一个单独的桌面空间，因此它应该具有单独的桌面号码。

我知道如何使用cgwindowlistcopywindowinfo获得打开的窗口列表，但是我找不到找到桌面号码的方法或确定哪个窗口可见。

如果不可能与Swift一起做，那么也许有Apple脚本解决方案？

您可以检索应用程序名称，边界＆amp;使用以下代码显示显示：

import Cocoa
import CoreGraphics

let windowsInfo = CGWindowListCopyWindowInfo(CGWindowListOption.optionAll, CGWindowID(0))
let maxDisplays: UInt32 = 10
var displays = [CGDirectDisplayID](repeating: 0, count: Int(maxDisplays))
var displayCount: UInt32 = 0
let error = CGGetOnlineDisplayList(maxDisplays, &displays, &displayCount)

for windowInfo in Array<NSDictionary>.fromCFArray(records: windowsInfo) ?? [] {
    if let appName = windowInfo["kCGWindowOwnerName"] as? String {
        print("appName: \(appName)")
    }
    if let bounds = windowInfo["kCGWindowBounds"] as? NSDictionary {
        print ("X: \(bounds["X"] ?? "<unknown>")")
        print ("Y: \(bounds["Y"] ?? "<unknown>")")
        print ("Width: \(bounds["Width"] ?? "<unknown>")")
        print ("Height: \(bounds["Height"] ?? "<unknown>")")

        if
            let x = bounds["X"] as? Double,
            let y = bounds["Y"] as? Double,
            let width = bounds["Width"] as? Double,
            let height = bounds["Height"] as? Double
        {
            for index in 0..<Int(maxDisplays) {
                let display = displays[index]
                let displayRect = CGDisplayBounds(display)
                if displayRect.contains(CGRect(x: x, y: y, width: width, height: height)) {
                    print("Display: \(index)")
                    break
                }
            }
        }

        print("---")
    }
}

extension Array {
    static func fromCFArray(records: CFArray?) -> Array<Element>? {
        var result: [Element]?
        if let records = records {
            for i in 0..<CFArrayGetCount(records) {
                let unmanagedObject: UnsafeRawPointer = CFArrayGetValueAtIndex(records, i)
                let rec: Element = unsafeBitCast(unmanagedObject, to: Element.self)
                if (result == nil){
                    result = [Element]()
                }
                result!.append(rec)
            }
        }
        return result
    }
}

示例输出：

使用此代码创建JSON对象是微不足道的。顺便说一句，您可能需要更改：

"size": {"x": 1080, "y": 1920}, 
"position": {"height": 0, "width": 0},

要

"position": {"x": 1080, "y": 1920}, 
"size": {"height": 0, "width": 0},

注意，没有UI的应用程序可能没有display值。
