ListView Sort maintaining color information

2 posts in this topic

#1 ·  Posted (edited)

Hi there,

I hope someone out there can help me. I'm populating a ListView with a number of items and have color-coded the rows. Top 3 in one color, the next 6 in another color, any remaining in a third color. When clicking the header, the items in the ListView sort, but the row colors remain the same. Does anyone know of a function that will sort the contents of the ListView and maintain color information?

So far, I've tried two methods to create the ListView:

Attempt 1, the most basic.

#include <GUIConstantsEx.au3>
#include <GUIListView.au3>

$Form = GUICreate("Form", 400, 500, 500, 200)

$Listview = GUICtrlCreateListView("Col 1|Col 2|Col 3", 20, 20, 300, 400)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 0, 150)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 1, 50)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 2, 50)

For $i = 1 to 18
    GUICtrlCreateListViewItem("Item 1|Item " & $i & "|Item " & (18 - $i), $Listview)
    If $i >= 1 And $i < 4 Then GUICtrlSetBkColor(-1, 0x00ff00)
    If $i >= 4 And $i < 10 Then GUICtrlSetBkColor(-1, 0x0000ff)
    If $i >= 10 Then GUICtrlSetBkColor(-1, 0xff0000)
 Next
 GUISetState(@SW_SHOW)

 Global $toggle = 1

While 1
    $nMsg = GUIGetMsg()
        Switch $nMsg
            Case $Listview
                _GUICtrlListView_SimpleSort($Listview, $toggle, GUICtrlGetState($Listview))

                If _GUICtrlListView_GetSelectedCount($Listview) Then 
                    $index = _GUICtrlListView_GetSelectedIndices($Listview, True) 
                    For $i = 1 To $index[0]
                        _GUICtrlListView_SetItemSelected($listview, $index[$i], False,False)
                    Next
                Endif

            Case $GUI_EVENT_CLOSE
                Exit
        EndSwitch
WEnd

Rows are colored correctly, but when sorting the color does not adjust accordingly.

Attempt 2 (partial), using a more advanced ListView:

$ListView = _GUICtrlListView_Create($Form, "", 20, 20, 300, 400)
_GUICtrlListView_AddColumn($ListView, "Col 1", 150)
_GUICtrlListView_AddColumn($ListView, "Col 2", 50)
_GUICtrlListView_AddColumn($ListView, "Col 3", 50)

For $i = 1 to 18
    _GUICtrlListView_AddItem($Listview, "Item 1", ($i-1))
    _GUICtrlListView_AddSubItem($Listview, ($i-1), "Item " & $i, 1)
    _GUICtrlListView_AddSubItem($Listview, ($i-1), "Item " & (18 - $i), 2)
    If $i >= 1 And $i < 4 Then _GUICtrlListView_SetTextBkColor($ListView, 0x00ff00)
Next

The SimpleSort function does not work with this method, but I didn't get as far as I was unable to find a way to individually color the rows - the _GUICtrlListView_SetTextBkColor function colors ALL rows the same.

Any assistance would be greatly appreciated...

 

EDIT:  Nevermind, have found a solution courtesy of BugFix's post >here. The SimpleSort in LV_Format_Include includes IParam, maintaining the row bkcolor.

It should be fixed in the latest beta.
