Cannot hilight a single selected cell in a ListView


Recommended Posts

I have a listview item with 4 columns and I want to hilight the cell (row,col) that I click on.

I have WM_NOTIFY code that detects the click, but I cannot get the single cell to be hilighted. It only hilights column 0 in any of the rows.

here is my test code:

#AutoIt3Wrapper_au3check_parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>
Opt('MustDeclareVars', 1)
Opt("GUIOnEventMode", 1) ; Change to OnEvent mode
Global $hMainWin, $hListView_Hwnd
Func _Main()
Local $flags = 0, $xflags = 0, $str, $x
$hMainWin = GUICreate("Main", 450, 160)
$flags = BitOR($flags, $LVS_REPORT)
$flags = BitOR($flags, $LVS_SHOWSELALWAYS)
$xflags = BitOR($xflags, $LVS_EX_GRIDLINES)
$xflags = BitOR($xflags, $LVS_EX_DOUBLEBUFFER)
$hListView_Hwnd = GUICtrlCreateListView("", 1, 1, 445, 150, $flags, $xflags)
For $x = 0 To 3
  _GUICtrlListView_InsertColumn($hListView_Hwnd, $x, "Col " & $x, 100)
For $x = 0 To 9
  $str = StringFormat("L%dC0|L%dC1|L%dC2|L%dC3", $x, $x, $x, $x)
  GUICtrlCreateListViewItem($str, $hListView_Hwnd)
GUISetOnEvent($GUI_EVENT_CLOSE, "Event_GUIClose")
EndFunc   ;==>_Main
Func WM_NOTIFY($hWnd, $msg, $wparam, $lparam)
#forceref  $hWnd, $Msg, $wParam, $lParam
Local $tNMBHOTITEM, $nNotifyCode, $hCtrl, $selrow, $selcol, $ar
$tNMBHOTITEM = DllStructCreate("hwnd hWndFrom;int IDFrom;int Code;dword dwFlags", $lparam)
$nNotifyCode = DllStructGetData($tNMBHOTITEM, "Code")
$hCtrl = DllStructGetData($tNMBHOTITEM, "hWndFrom")
Switch $nNotifyCode
  Case $NM_CLICK
   $ar = _GUICtrlListView_SubItemHitTest($hCtrl)
   $selrow = $ar[0]
   $selcol = $ar[1]
   ConsoleWrite("+++: $NM_CLICK - row " & $selrow & ", col " & $selcol & @CRLF)
   $ar = _GUICtrlListView_SubItemHitTest($hCtrl)
   $selrow = $ar[0]
   $selcol = $ar[1]
   ConsoleWrite("+++: $NM_DBLCLK - row " & $selrow & ", col " & $selcol & @CRLF)
EndFunc   ;==>WM_NOTIFY
Func Event_GUIClose()
Exit (0)
EndFunc   ;==>Event_GUIClose

Search for NM_CUSTOMDRAW and you will find examples.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

How about this as a simple workaround - needs polishing but it proves the concept: ;)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>
#include <Constants.au3>
#Include <GuiEdit.au3>

Global $iOffset_X = 10, $iOffset_Y = 1
Global $fClick = False, $hLabel

$GUI = GUICreate("Test", 500, 500)

$ListView = _GUICtrlListView_Create($GUI, "Col 0|Col 1", $iOffset_X, $iOffset_Y, 480, 480)

For $i = 0 To 4
    $iIndex = _GUICtrlListView_AddItem($ListView, "TEST" & $i)
    _GUICtrlListView_AddSubItem($ListView, $iIndex, "TEST1" & $i, 1)

_GUICtrlListView_SetColumnWidth($ListView, 0, 240)
_GUICtrlListView_SetColumnWidth($ListView, 1, $LVSCW_AUTOSIZE_USEHEADER)

$GUIshow = GUISetState()

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")                       ; For click on ListView

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE

    ; If a ListView was clicked
    If $fClick Then
        $aHit = _GUICtrlListView_SubItemHitTest($ListView)
        If $aHit[0] <> -1 Then
        $fClick = False


Func _HighLight()

    ; Prevent resizing of columns
    ControlDisable($GUI, "", HWnd(_GUICtrlListView_GetHeader($ListView)))
    ; Get current text
    $sItemOrgText = _GUICtrlListView_GetItemText($ListView, $aHit[0], $aHit[1])
    ; Get size of Label
    Local $aRect = _GUICtrlListView_GetSubItemRect($ListView, $aHit[0], $aHit[1])
    ; Delete any existing Label
    ; Cretae a new label
    $hLabel = GUICtrlCreateLabel($sItemOrgText, $aRect[0] + $iOffset_X + 5, $aRect[1] + $iOffset_Y, _GUICtrlListView_GetColumnWidth($ListView, $aHit[1]) - 7, $aRect[3] - $aRect[1], Default, $WS_EX_TOPMOST)
    GUICtrlSetBkColor(-1, 0xFF0000)
    GUICtrlSetColor(-1, 0xFFFFFF)


Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

    #forceref $hWnd, $iMsg, $wParam

    Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    Local $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    Local $iCode = DllStructGetData($tNMHDR, "Code")
    ; Check if a ListView has sent the message
    If $hWndFrom = $ListView Then
        Switch $iCode
            Case $NM_CLICK
                ; Set flag
                $fClick = True



I hope it helps. :graduated:
