Row index of a controlID in ListView after sorting?

4 posts in this topic

Hi, I have simple question. How to remain Index (Row) of a ControlID after sorting in ListView?

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>

Dim $nCurCol = -1
Dim $nSortDir = 1
Dim $bSet = 0
Dim $nCol = -1
Dim $MyArr[10]
Dim $CtlrID[10]

_dumpArr_for_test_only()

; GUI
GUICreate("Retrieve Row after sorting",220, 270)
$hListView = GUICtrlCreateListView ("colA|colB|colC|colD",10, 10, 200, 200)
$Btn_Ret  = GUICtrlCreateButton("Retrieve Row from $CtlrID[5]", 25, 230, 170, 25, 0)
GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)
; create rows
For $i = 0 To UBound($MyArr) - 1
    $CtlrID[$i] = GUICtrlCreateListViewItem($MyArr[$i], $hListView) ;
Next
GUICtrlSetBkColor ($CtlrID[5], 0xff0000)
GUICtrlRegisterListViewSort($hListView, "LVSort")
GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $Btn_Ret
            msgbox (0,"Row No.", "RowIndex (Index) of $CtlrID[5] is: " & "??")  ;?? <= I need get Row (Index) from ControlID
        Case $hListView
            $bSet = 0
            $nCurCol = $nCol
            DllCall("user32.dll", "int", "InvalidateRect", "hwnd", GUICtrlGetHandle($hListView), "int", 0, "int", 1)
    EndSwitch
WEnd

; for example only
Func _dumpArr_for_test_only()
Local $bTmp = true, $sTmp
    For $i = 0 To UBound($MyArr) - 1
        Switch $i
            Case 2, 5, 7

        $bTmp = Not $bTmp
        $MyArr[$i] = $i & "|" & UBound($MyArr)-$i-1  & "|" & $bTmp & "|" & $sTmp
    Next   
EndFunc

; Our sorting callback funtion
Func LVSort($hWnd, $nItem1, $nItem2, $nColumn)
    Local $nSort
    Local $tInfo = DllStructCreate($tagLVFINDINFO)
    DllStructSetData($tInfo, "Flags", $LVFI_PARAM)
     ; Switch the sorting direction
    If $nColumn = $nCurCol Then
        If Not $bSet Then
            $nSortDir = $nSortDir * - 1
            $bSet = 1
        EndIf
    Else
        $nSortDir = 1
    EndIf
    $nCol = $nColumn
     DllStructSetData($tInfo, "Param", $nItem1)
    $val1 = _GUICtrlListView_FindItem($hWnd, -1, $tInfo)
    DllStructSetData($tInfo, "Param", $nItem2)
    $val2 = _GUICtrlListView_FindItem($hWnd, -1, $tInfo)
    $val1 = _GUICtrlListView_GetItemText($hWnd, $val1, $nColumn)
    $val2 = _GUICtrlListView_GetItemText($hWnd, $val2, $nColumn)
    $nResult = 0 ; No change of item1 and item2 positions
    If $val1 < $val2 Then
        $nResult = -1 ; Put item2 before item1
    ElseIf $val1 > $val2 Then
        $nResult = 1 ; Put item2 behind item1
