Sorting Listview with Checkboxes

5 posts in this topic

Hi,

I've some problems sorting listview which contains checkboxes. I figured out that a listview with checkboxes can't be sorted by _GUICtrlListView_SimpleSort. So I took a look at _GUICtrlListView_SortItems. The example in the helpfile works fine, but I cant get it to work if the listview contains no images. I modified the code from helpfile to get closer to this behavior. After all I had a listview which fires _GUICtrlListView_SortItems, shows up arrows in the columheader but isn''t sorted.

This is the code (modified code from the helpfile)

CODE
#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6

#include <GUIConstantsEx.au3>

#include <GuiListView.au3>

#include <GuiImageList.au3>

#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

Global $hListView, $hListView2

_Example1()

_Example2()

Func _Example1()

Local $hImage, $aIcons[3] = [0, 3, 6]

Local $iExWindowStyle = BitOR($WS_EX_DLGMODALFRAME, $WS_EX_CLIENTEDGE)

Local $iExListViewStyle = BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_SUBITEMIMAGES, $LVS_EX_GRIDLINES, $LVS_EX_CHECKBOXES, $LVS_EX_DOUBLEBUFFER)

GUICreate("ListView Sort", 300, 200)

$hListView = GUICtrlCreateListView("Column1|Col2|Col3", 10, 10, 280, 180, -1, $iExWindowStyle)

_GUICtrlListView_SetExtendedListViewStyle($hListView, $iExListViewStyle)

_AddRow($hListView, "ABC|000666|10.05.2004")

_AddRow($hListView, "DEF|444|11.05.2005")

_AddRow($hListView, "CDE|555|12.05.2004")

_GUICtrlListView_RegisterSortCallBack($hListView)

Local $tInfo = DllStructCreate($tagNMLISTVIEW, $ilParam)

; Kick off the sort callback

_GUICtrlListView_SortItems($hWndFrom, DllStructGetData($tInfo, "SubItem"))

; No return value

EndSwitch

EndSwitch

Return $__LISTVIEWCONSTANT_GUI_RUNDEFMSG

EndFunc ;==>_WM_NOTIFY

Can anyone take a look at the code and help me. I can't figure out why the listview isn't sorted.

Many thanks in advance

Add a $iParam - Application Defined data in a _GUICtrlListView_AddItem() function.

many thanks for help. This does the trick.

I wasn't able to find out what's meant by "Application Defined data" and for what it's used.

best wishes

Paul

Maybe it is an idea to be a bit more specific on this topic in the helpfile?

Spent 2 full days trying to figure out OP's problem. Simple line in the helpfile, that you need to define a $iParam for _GuiCtrlListview_SortItems() to work, would have made all the difference.
