确定 window 在哪个屏幕上（通过检查最大表面积所在的位置）

Question

我目前正在确定 window 在哪个屏幕上，方法是检查它位于哪个屏幕的最左上角位置。现在我想改变它，这样我就可以找出在哪个屏幕上可以找到 window 的最大表面积。
有什么想法可以实现吗？

这是我的旧代码：（它只是在按 F1 时在所有可用屏幕之间移动活动 window）

F1::
    WinGetPos, X, Y,,, A
    window := {x:X,y:Y}
    monitors := GetMonitors()
    Loop % monitors.MaxIndex() {
        curMonitor := monitors[A_Index]
        If IsPointInRectange(window,curMonitor) {
            nextMonitorIndex := (A_Index = monitors.MaxIndex() ? 1 : A_Index+1)
            nextMonitor := monitors[nextMonitorIndex]
            percPos := {}
            percPos.x := (window.x-curMonitor.x1)/(curMonitor.x2-curMonitor.x1)
            percPos.y := (window.y-curMonitor.y1)/(curMonitor.y2-curMonitor.y1)
            windowNew := {}
            windowNew.x := nextMonitor.x1+(nextMonitor.x2-nextMonitor.x1)*percPos.x
            windowNew.y := nextMonitor.y1+(nextMonitor.y2-nextMonitor.y1)*percPos.y
            WinMove, A,, windowNew.x, windowNew.y

        }
    }
Return

IsPointInRectange(point,rect) {
    If point.x >= rect.x1 && point.x < rect.x2
    && point.y >= rect.y1 && point.y < rect.y2
       Return True
}

GetMonitors() {
    monitors := []
    SysGet, monCount, 80 ;SM_CMONITORS
    Loop % monCount {
        SysGet, mon, Monitor, %A_Index%
        monitors[A_Index] := {x1: monLeft, x2: monRight, y1: monTop, y2: monBottom}
    }
    Return monitors
}

MonitorFromWindow() 是解决方案。 :) 这是新代码：

;Win+Enter to move the active window to the next screen
#Enter::
    WinGet, activeWindowHwnd, ID, A
    activeMonitorHwnd := MDMF_FromHWND(activeWindowHwnd)
    monitors := MDMF_Enum()

    monitorHwndList := []
    For currentMonitorHwnd, info In monitors
        monitorHwndList[A_Index] := currentMonitorHwnd

    nextMonitorHwnd := ""
    For currentMonitorHwnd, info In monitors
        If (currentMonitorHwnd = activeMonitorHwnd)
            nextMonitorHwnd := (A_Index=monitorHwndList.MaxIndex() ? monitorHwndList[1] : monitorHwndList[A_Index+1])

    activeMonitor := MDMF_GetInfo(activeMonitorHwnd)
    nextMonitor := MDMF_GetInfo(nextMonitorHwnd)

    WinGetPos, x, y, w, h, ahk_id %activeWindowHwnd%
    activeWindow := {Left:x, Top:y, Right:x+w, Bottom:y+h}

    relativePercPos := {}
    relativePercPos.Left := (activeWindow.Left-activeMonitor.Left)/(activeMonitor.Right-activeMonitor.Left)
    relativePercPos.Top := (activeWindow.Top-activeMonitor.Top)/(activeMonitor.Bottom-activeMonitor.Top)
    relativePercPos.Right := (activeWindow.Right-activeMonitor.Left)/(activeMonitor.Right-activeMonitor.Left)
    relativePercPos.Bottom := (activeWindow.Bottom-activeMonitor.Top)/(activeMonitor.Bottom-activeMonitor.Top)

    ;MsgBox % activeWindow.Top "`n" activeWindow.Left " - " activeWindow.Right "`n" activeWindow.Bottom
    ;MsgBox % relativePercPos.Top*100 "`n" relativePercPos.Left*100 " - " relativePercPos.Right*100 "`n" relativePercPos.Bottom*100

    activeWindowNewPos := {}
    activeWindowNewPos.Left := nextMonitor.Left+(nextMonitor.Right-nextMonitor.Left)*relativePercPos.Left
    activeWindowNewPos.Top := nextMonitor.Top+(nextMonitor.Bottom-nextMonitor.Top)*relativePercPos.Top

    WinMove, A,, activeWindowNewPos.Left, activeWindowNewPos.Top
Return
