NSWindow定位

我是Hearthstone tracker的作者,我必须在Hearthstone窗口上移动几个NSWindow

我使用CGWindowListCopyWindowInfo得到了炉石的框架。 然后,我必须在相对于炉石的某些位置移动我的窗户。

HSTracker overlays 红色箭头超过对手卡片,绿色箭头超过转动按钮,蓝色箭头位于窗口的左侧和右侧。

我的实际屏幕设置如下:

Screen setup

给了我以下框架

// screen 1 : {x 0 y 0 w 1.440 h 900}
// screen 2 : {x 1.440 y -180 w 1.920 h 1.080}

要将对手跟踪器(左框架)放置在正确的位置,这是最简单的情况,我使用{x 0 y somepadding w 185 h hearthstoneHeight - somepadding}并使用此

获取正确的框架
func relativeFrame(frame: NSRect) -> NSRect {
    var relative = frame
    relative.origin.x = NSMinX(hearthstoneFrame) + NSMinX(frame)
    relative.origin.y = NSMinY(hearthstoneFrame) + NSMinY(frame)

    return relative
}

使用{x hearthstoneWidth - trackerWidth, ...}

放置正确的跟踪器

对于其他叠加层,我使用当前(炉石)分辨率放置它们并使用简单的数学计算它们

x = x / 1404.0 * NSWidth(hearthstoneFrame)
y = y / 840.0 * NSHeight(hearthstoneFrame)

这非常有效。除非我使用我的第二个屏幕。在这种情况下,框架似乎是正确的,但窗口的位置不好。

以下是{x 0 y 0 w hearthstoneWidth h hearthsoneHeight }调试窗口的屏幕截图。如果我比较炉石和我的叠加的帧,它们是相同的。 Debug overlay

完整的功能如下(我在#34;静态类"我只显示重要代码)。我想我在计算中遗漏了一些东西,但我找不到。

class frameRelative {
   static var hearthstoneFrame = NSZeroRect
   static func findHearthstoneFrame() {
       let options = CGWindowListOption(arrayLiteral: .ExcludeDesktopElements)
       let windowListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
       if let info = (windowListInfo as NSArray? as? [[String: AnyObject]])?
           .filter({
              !$0.filter({ $0.0 == "kCGWindowName" && $0.1 as? String == "Hearthstone" }).isEmpty
            })
            .first {
              var rect = NSRect()
              let bounds = info["kCGWindowBounds"] as! CFDictionary
              CGRectMakeWithDictionaryRepresentation(bounds, &rect)
              rect.size.height -= titleBarHeight // remove the 22px from the title
              hearthstoneFrame = rect
       }
  }

  static func frameRelative(frame: NSRect, _ isRelative: Bool = false) -> NSRect {
      var relative = frame
      var pointX = NSMinX(relative)
      var pointY = NSMinY(relative)

      if isRelative {
          pointX = pointX / 1404.0 * NSWidth(hearthstoneFrame)
          pointY = pointY / 840.0 * NSHeight(hearthstoneFrame)
      }

      let x: CGFloat = NSMinX(hearthstoneFrame) + pointX
      let y = NSMinY(hearthstoneFrame) + pointY

      relative.origin = NSMakePoint(x, y)
      return relative
  }
}

// somewhere here
let frame = NSMakeRect(0, 0, hearthstoneWidth, hearthstoneHeight)
let relativeFrame = SizeHelper.frameRelative(frame)
myWindow.setFrame(relativeFrame, display: true)

任何帮助将不胜感激:)

I eventually solved this issue so I decided to post the answer to close this thread... and maybe if someone face the same issue one day.

The solution was to substract the max y from the first screen with the max y of the Hearthstone window.

The final code of findHearthstoneFrame is

static func findHearthstoneFrame() {
   let options = CGWindowListOption(arrayLiteral: .ExcludeDesktopElements)
        let windowListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
        if let info = (windowListInfo as NSArray? as? [[String: AnyObject]])?.filter({
            !$0.filter({ $0.0 == "kCGWindowName"
                && $0.1 as? String == "Hearthstone" }).isEmpty
        }).first {
            if let id = info["kCGWindowNumber"] as? Int {
                self.windowId = CGWindowID(id)
            }
            var rect = NSRect()
            let bounds = info["kCGWindowBounds"] as! CFDictionary
            CGRectMakeWithDictionaryRepresentation(bounds, &rect)

            if let screen = NSScreen.screens()?.first {
                rect.origin.y = NSMaxY(screen.frame) - NSMaxY(rect)
            }

            self._frame = rect
        }
 }

And the frameRelative is

static let BaseWidth: CGFloat = 1440.0
static let BaseHeight: CGFloat = 922.0
var scaleX: CGFloat {
    return NSWidth(_frame) / SizeHelper.BaseWidth
}

var scaleY: CGFloat {
    // 22 is the height of the title bar
    return (NSHeight(_frame) - 22) / SizeHelper.BaseHeight
}
func frameRelative(frame: NSRect, relative: Bool = true) -> NSRect {
    var pointX = NSMinX(frame)
    var pointY = NSMinY(frame)
    let width = NSWidth(frame)
    let height = NSHeight(frame)

    if relative {
        pointX = pointX * scaleX
        pointY = pointY * scaleY
    }

    let x: CGFloat = NSMinX(self.frame) + pointX
    let y: CGFloat = NSMinY(self.frame) + pointY

    let relativeFrame = NSRect(x: x, y: y, width: width, height: height)
    return relativeFrame
}
