set Listview item color and attribute

4 posts in this topic

I want to set an item's color and attribute (bold, italics, etc.) in a listview. (I am forced to create the listview and it's individual items using _GUICtrlListView_... functions due to a sort issue.)

My test code looks like this:

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <ColorConstants.au3>
#include <FontConstants.au3>

Opt("GUICloseOnESC", 1) ; ESC closes GUI
Opt("GUIOnEventMode", 1) ; Change to OnEvent mode
Opt('MustDeclareVars', 1)

exit (1)

Func _Main()
    Local $hMainWin, $hListview, $IDListview, $aList[10]

    For $x = 0 To UBound($aList) - 1
        For $y = 0 To 3
            $aList[$x] &= Chr(0x41 + $x) & $y & "|" ; Load the list with values

    $hMainWin = GUICreate("Test2", 320, 220)
    $hListview = createListView($hMainWin)
    loadItemsListView($hListview, $aList)

    GUISetOnEvent($GUI_EVENT_CLOSE, 'Event_GUIClose') ; CLOSE events

    setListViewRowColor($hListview, 1, $COLOR_RED, $aList)
    setListViewRowAttr($hListview, 3, $FW_BOLD, $aList)


    Until GUIGetMsg() = $GUI_EVENT_CLOSE
EndFunc   ;==>_Main

Func createListView($hWndMain)
    Local $flags, $xflags, $hWnd
    $flags = BitOR($LVS_REPORT, $flags, $LVS_SHOWSELALWAYS)
    $hWnd = _GUICtrlListView_Create($hWndMain, "Col1|col2|col3|col4", 10, 10, 300, 200, $flags)
    _GUICtrlListView_SetExtendedListViewStyle($hWnd, $xflags)
    return ($hWnd)
EndFunc   ;==>createListView

Func loadItemsListView($hWnd, ByRef $ar)
    Local $row, $item, $aItem, $iIndex


    For $row = 0 To UBound($ar) - 1
        $item = $ar[$row]
        $aItem = StringSplit($item, "|") ; Break the item into parts
        $iIndex = _GUICtrlListView_AddItem($hWnd, $aItem[1], -1, $row)
        For $ndx = 2 To UBound($aItem) - 1
            _GUICtrlListView_AddSubItem($hWnd, $iIndex, $aItem[$ndx], $ndx - 1)
EndFunc   ;==>loadItemsListView

Func Event_GUIClose()
    exit (0)
EndFunc   ;==>Event_GUIClose

Func setListViewRowColor($hWnd, $iItemNum, $iColor, ByRef $ar)
EndFunc   ;==>setListViewRowColor

Func setListViewRowAttr($hWnd, $iItemNum, $iAttr, ByRef $ar)
EndFunc   ;==>setListViewRowAttr

I need to fill in code in the setListViewRowColor() and setListViewRowAttr() functions.

Have you tried to search "Example Scripts" section? I remember that long ago I've seen someting similar made by Yashied or Rasim ...

Have a look, I'm pretty sure you'll find something you can use.

SNMP_UDF ... for SNMPv1 and v2c so far, GetBulk and a new example script

Or why not use small icons/bitmaps, search _GUICtrlListView_CreateSolidBitMap() in the Help File. This is what I have done in the past to show if (for example) a file has copied or not (green/red)

OK, I solved it using code I found by Googling the problem. What I had to do was hook into the $NM_CUSTOMDRAW event for the listbox. Actually, it's pretty slick. All I had to do was to set each item's param with a color number when I added them to the listview, and in the hook code, read the color number and convert it to a RGB color, then set the clrText element to that value. It was important that I surround the listbox item creation with a _GUICtrlListView_BeginUpdate() and _GUICtrlListView_EndUpdate() to keep from firing off $NM_CUSTOMDRAW events. When the _GUICtrlListView_EndUpdate() is called, there will be an $NM_CUSTOMDRAW event fired off for each item. That's where I added the color.

This technique could be used to set text to bold, italics, etc. as well.

Here is a test script that demonstrates what I'm talking about:

#include <GuiConstants.au3>
