Rearrange Windows

Recommended Posts


I made this script to search for all open/visible windows with title which contains string ATHENA and put them into an array and after that arrange those windows side by side.

My problem is that I also whant at the end to delete the arrays completely.I have searched the forum , tried examples but I didn't managed to empty/delete the arrays.

#include <Array.au3>

Global $GUIVersion = "0.0"
Global $GUITitle = "Athena Windows Rearrange v" & $GUIVersion

Global $HandlesArray[1]
Global $TitlesArray[1]


Local $Paused
HotKeySet("{PAUSE}", "_TogglePause")
HotKeySet("{ESC}", "_Terminate")

#Region ### START Koda GUI section ### Form=g:\script\positons final\gui.kxf
;~ $GUI = GUICreate($GUITitle, 400, 400, -1, -1)
;~ GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###


$rows = UBound($TitlesArray)-1
    If $rows = 0 Then
        $msgtext = "Could not find any open ATHENA projects" & @CRLF & "Please open some for me !"
        MsgBox ( 0, "Error", $msgtext)
    ElseIf $rows = 1 Then
        MsgBox(0, "Error", "I found just one ATHENA window" & @CRLF & "Nothing to do !")
        ;_Delete ($TitlesArray)
        ;_Delete ($HandlesArray)


Func _CreateArrays()
    $var = WinList()
        For $i = 1 to $var[0][0]
            ; Only display visble windows that have a title
            If $var[$i][0] <> "" AND IsVisible($var[$i][1]) Then
                $nOffset = 1 ;Option 1, using offset
                $asResult=StringRegExp($var[$i][0], "ATHENA", 1, $nOffset)          ; Search windows titles that contains "ATHENA" sting
                    If @error = 0 Then
                        _ArrayAdd($HandlesArray, $var[$i][1])                       ; array with only "Athena" -handels- 
                        _ArrayAdd($TitlesArray, $var[$i][0])                        ; array with only "Athena" -title names-
;~  _ArrayDisplay($HandlesArray, "Array: ATHENA handles")
;~  _ArrayDisplay($TitlesArray, "Array: ATHENA titles")

EndFunc ;==> Create arrays for existing Athena windows

Func IsVisible($handle)
  If BitAnd( WinGetState($handle), 2 ) Then
    Return 1
    Return 0
EndFunc ;==> Checkes window state is visible

Func _RearangeWindows()
    $WindowsNumber = UBound($TitlesArray)-1                         ;total windows number in Titels Array
    For $i=1 to $WindowsNumber
        If Mod($i, 2) <> 0 Then                                     ;check if a number is even or not
            WinMove ($HandlesArray[$i], "",0 ,0 , $W, $H)
            WinMove ($HandlesArray[$i], "", @DesktopWidth/2, 0, $W, $H)
EndFunc ;==> Arange windows side by side

Func _TogglePause ()
    $Paused = NOT $Paused
    While $Paused
        ToolTip($GUITitle & ' is "Paused"',@DesktopHeight/2,@DesktopWidth/2, "", 0, 2)
EndFunc ;==> TogglePause

Func _Terminate ()
    MsgBox(0, $GUITitle, "Exit!")
    Exit 0
EndFunc ;==> Terminate

This is what I tried

_Delete ($TitlesArray)
_Delete ($HandlesArray)

Func _Delete ($aArray)

For $i = 1 To Ubound($aArray)-1

    _ArrayDelete($aArray, 0) ; Always the first element until $aArray = "" or nothing.
;_ArrayDisplay($aArray, "Array after delete")

It is even easier than NerdFencer thinks! :D From the Help file:

"To erase an array (maybe because it is a large global array and you want to free the memory), simply assign a single value to it:

$array = 0

This will free the array and convert it back to the single value of 0"

No need for ReDim or assigning a valuesto an element.
