Focus Follows Mouse

[WideBoyDixon]

Just wrote this as a proof of concept at the moment but I thought I'd share. This script forces the focus to follow the mouse. When the mouse leaves the window then it attempts to restore the previous z-order of the window, based on the order they were retrieved by WinList() in the first place.

#include <Constants.au3>
#include <WinAPI.au3>

Opt("MustDeclareVars", 1)

Global $aWin, $i, $aMousePos, $aWinPos, $hCurrent = 0, $hAfter = 0, $hLast

While True
    $aWin = WinList()
    $aMousePos = MouseGetPos()
    $hLast = 0
    For $i = 1 To $aWin[0][0]
        If BitAND(WinGetState($aWin[$i][1]), 2) Then
            $aWinPos = WinGetPos($aWin[$i][1])
            If ($aMousePos[0] >= $aWinPos[0]) And ($aMousePos[0] < $aWinPos[0] + $aWinPos[2]) And ($aMousePos[1] >= $aWinPos[1]) And ($aMousePos[1] < $aWinPos[1] + $aWinPos[3]) Then
                If Not WinActive($aWin[$i][1]) Then
                    If ($aWin[$i][1] <> $hCurrent) Then
                        If IsHwnd($hCurrent) And ($hAfter <> 0) Then
                            _WinAPI_SetWindowPos($hCurrent, $hAfter, 0, 0, 0, 0, BitOR($SWP_NOMOVE, $SWP_NOSIZE))
                        EndIf
                        $hCurrent = $aWin[$i][1]
                        $hAfter = $hLast
                        WinActivate($hCurrent)
                    EndIf
                EndIf
                ExitLoop
            EndIf
            $hLast = $aWin[$i][1]
        EndIf
    Next
WEnd

I have seen some strange behaviour with it so it's probably not 100% right but it's a start at least. Have fun.

Nice work!

I modified it by adding a delay and a sleep function:

#include <Constants.au3>
#include <WinAPI.au3>

Opt("MustDeclareVars", 1)

Global $aWin, $i, $aMousePos, $aWinPos, $hCurrent = 0, $hAfter = 0, $hLast, $timer, $delay = 0.005

While True
    $aWin = WinList()
    $aMousePos = MouseGetPos()
    $hLast = 0
    For $i = 1 To $aWin[0][0]
        If BitAND(WinGetState($aWin[$i][1]), 2) Then
            $aWinPos = WinGetPos($aWin[$i][1])
            If ($aMousePos[0] >= $aWinPos[0]) And ($aMousePos[0] < $aWinPos[0] + $aWinPos[2]) And ($aMousePos[1] >= $aWinPos[1]) And ($aMousePos[1] < $aWinPos[1] + $aWinPos[3]) Then
                If Not WinActive($aWin[$i][1]) Then
                    $timer = TimerInit()
                    If ($aWin[$i][1] <> $hCurrent) Then
                        If IsHwnd($hCurrent) And ($hAfter <> 0) Then
                            _WinAPI_SetWindowPos($hCurrent, $hAfter, 0, 0, 0, 0, BitOR($SWP_NOMOVE, $SWP_NOSIZE))
                        EndIf
                        $hCurrent = $aWin[$i][1]
                        $hAfter = $hLast
                        If TimerDiff($timer) > $delay Then WinActivate($hCurrent)
                    EndIf
                EndIf
                ExitLoop
            EndIf
            $hLast = $aWin[$i][1]
        EndIf
        Sleep(10)
    Next
WEnd

This is actually very clever. Could be useful for Mac users, saves them even more effort

Edit: Hover over the taskbar, it brings up the previous window O_o

Also, after I closed the script when I select a window from the tasklist it don't get the top most again. One window is fixed to be the top most.

That's the strange behaviour I had! Some windows seem to get fixed as topmost so I couldn't see windows underneath them unless they were minimised (or moved). I was hoping someone could figure it out - it must be to do with SetWindowPos but I tried to avoid it by checking for a zero $hAfter

I like the idea of having a delay and a sleep in there; thanks for your input.

There's still something not quite right here but I've made this a little better. I've also allowed configuration of the options to try and match the X-Mouse functionality in TweakUI.

Then again, maybe I'll just use TweakUI (although it's not portable) as it obviously has a sneaky advantage up it's sleeve of being able to activate a window without bringing it to the front.

Seems to be working now. Well done
