GUiCtrlListView and the $GUI_BKCOLOR_LV_ALTERNATE

[Achilles]

I've been trying to apply $GUI_BKCOLOR_LV_ALTERNATE to a listview. I've tried it as a normal style, as an extended style and with GuiCtrlSetState... However it doesn't seem to be working. The helpfile says this:

The special flag $GUI_BKCOLOR_LV_ALTERNATE can be used with Listview control to give alternate background of the ListviewItems lines.

But I'm not sure how to actually apply the "special flag"... Any help would be great...

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <WindowsConstants.au3>

Global $hListView, $hLIstView2
Global $gui, $btn

$gui = GUICreate("ListView Sort", 600, 300)
$hListView = GUICtrlCreateListView("Column1|Col2|Col3", 10, 10, 280, 180)
    GUICtrlSetState(-1, $GUI_BKCOLOR_LV_ALTERNATE)

_AddRow($hListView, "ABC|000666|10.05.2004")
_AddRow($hListView, "DEF|444|11.05.2005")
_AddRow($hListView, "CDE|555|12.05.2004")

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop

    EndSwitch
WEnd

GUIDelete()

Func _AddRow($hWnd, $sItem)
    Local $aItem = StringSplit($sItem, "|")
    Local $iIndex = _GUICtrlListView_AddItem($hWnd, $aItem[1], -1, _GUICtrlListView_GetItemCount($hWnd) + 9999)

    For $x = 2 To $aItem[0]
        _GUICtrlListView_AddSubItem($hWnd, $iIndex, $aItem[$x], $x - 1)
    Next
EndFunc  ;==>_AddRow

I use a version of this by Siao. I couldn't get $GUI_BKCOLOR_LV_ALTERNATE to work.

Basic idea:

#include <GuiConstantsEx.au3>

$GUI = GUICreate("dummy", 100, 400)
$LV = GUICtrlCreateListView("Items", 0, 0, 100, 400)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_LV_ALTERNATE)
For $i = 1 To 10
    GUICtrlCreateListViewItem("Item" & $i, $LV)
    GUICtrlSetBkColor(-1, 0xE6E6E6)
Next
GUISetState()

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Could you do that with the _GUICtrlListView_AddItem? Or do you have to use GUICtrlCreateListViewitem?

No. For items created with GuiListView.au3 UDF functions use this code:

Global $Font2 = _WinAPI_CreateFont(14, 0, 0, 0, $FW_NORMAL, False, False, False, $DEFAULT_CHARSET, $OUT_DEFAULT_PRECIS, _
                                   $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, "MS Sans Serif")

$hGUI = GUICreate("Test", 300, 200)

$hListView = _GUICtrlListView_Create($hGUI, "Items|SubItems|", 10, 10, 280, 180, $LVS_REPORT, $WS_EX_CLIENTEDGE)

_GUICtrlListView_SetExtendedListViewStyle($hListView, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT, $LVS_EX_INFOTIP))

For $i = 1 To 10
    _GUICtrlListView_AddItem($hListView, "Item" & $i)
