ListView Sort and row Background Color

Recommended Posts

Tec

Hi

i need some help with Listview Sort and Background Color.

Example:

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


$Gui = GUICreate("Test", 300, 200)
$hListView = GUICtrlCreateListView("Client | Status", 5, 0, 290, 250)
GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)

For $a = 1 To 10
        if $a = 4 then
            GUICtrlCreateListViewItem("PC" & $a & "| Offline", $hListView)
            GUICtrlSetBkColor(-1, 0xFF0000)
        else
            GUICtrlCreateListViewItem("PC" & $a & "| Online", $hListView)
        EndIf
Next

GUISetState()

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
Global $B_DESCENDING[_GUICtrlListView_GetColumnCount($hListView)]

While 1
    $msg = GUIGetMsg()
    Switch $msg
    Case $GUI_EVENT_CLOSE
        ExitLoop
    EndSwitch
    Sleep( 10 )
WEnd
Exit

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView
    $hWndListView = $hListView
    If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iCode = DllStructGetData($tNMHDR, "Code")

    Switch $hWndFrom
    Case $hWndListView
        Switch $iCode
        Case $LVN_COLUMNCLICK
            Local $tInfo = DllStructCreate($tagNMLISTVIEW, $ilParam)
            _GUICtrlListView_SimpleSort($hWndListView, $B_DESCENDING, DllStructGetData($tInfo, "SubItem"))
        EndSwitch
    EndSwitch
EndFunc

I want to highlight all Offline clients. But how can I highlight the offline Clients if the order change? I read something about $NM_CUSTOMDRAW and read the post from Siao but i dont understand this. Need some small Example/help please.

Good morning

I change the code to highlight the complete row. But two more question I have.

1. Is the code modification the right way ? It works for me but I am a little bit confusion about the Return Values $CDRF_NEWFONT and $CDRF_NOTIFYSUBITEMDRAW

2. Is there a simple way to highlight only the "offline" cell ?

thx for help

Don't ask me about the why's, thats just the way its documented ;)...

2. Is there a simple way to highlight only the "offline" cell ?

According to this MSDN article, I would have expected a $CDDS_SUBITEM drawing stage... but case else also seems to work fine :blink:...
