Another relatively simple question, I was wonderign if someone could give me a command to reference in the help file in relation to adding checkboxes to a list view.

I also want to make it so only one check box can be selected, I think in order to do this I need to be able to detect when a checkbox is checked, and uncheck any others that have been checked, is there any way of detecting each time a checkbox is selected?

nullschritt,

I would do it like this:

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

$hGUI = GUICreate("Test", 500, 500)

$cListView = GUICtrlCreateListView("Column1", 10, 10, 480, 250, Default, $LVS_EX_CHECKBOXES)

$cStart = GUICtrlCreateDummy()
For $i = 0 To 9
    GUICtrlCreateListViewItem("Item " & $i, $cListView)
Next
$cEnd = GUICtrlCreateDummy()

GUISetState()

While 1

    $iMsg = GUIGetMsg()
    Switch $iMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cStart + 1 To $cEnd - 1
            ; Which item was clicked - possibly on checkbox?
            $iIndex = $iMsg - ($cStart + 1)
            ; Is this item clicked?
            If _GUICtrlListView_GetItemChecked($cListView, $iIndex) Then
                ; Delete all checks
                For $i = 0 To _GUICtrlListView_GetItemCount($cListView) - 1
                    ; Except the one just made
                    If $i <> $iIndex Then
                        _GUICtrlListView_SetItemChecked($cListView, $i, False)
                    EndIf
                Next
            EndIf
    EndSwitch

WEnd
All clear? :)

Hi,

I would do it this way as the main while will be more responsive :

#include <GUIListView.au3>
 
Global Const $LVM_CHECKED = 8192, $LVM_UNCHECKED = 4096
 
Global $iLastItemChecked = -1
 
#region GUI
Local $hGUI = GUICreate("MyGUI", 500, 500)
 
Global $iLw1 = GUICtrlCreateListView("Column1", 10, 10, 480, 250, Default, $LVS_EX_CHECKBOXES)
 
For $i = 0 To 9
    GUICtrlCreateListViewItem("Item " & $i, $iLw1)
Next
 
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
GUISetState(@SW_SHOW, $hGUI)
#endregion
 
While GUIGetMsg() <> $GUI_EVENT_CLOSE
    Sleep(10)
WEnd

Thanks works great, but I am having one tiny problem, when I initially load the data from the database, I need to check to see which row is the primary row, and automatically check it, this I have done, HOWEVER, there is an issue with this, as this box will remain checked, until unchecked(unlike the other checkboxes, it will not automatically uncheck itself, allowing two boxes to be checked), is there a workaround for this, maybe a way to clear all checkboxes and then check the selected one?

Observe below:

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <GUIListView.au3>
 
Global Const $LVM_CHECKED = 8192, $LVM_UNCHECKED = 4096
 
Global $iLastItemChecked = -1
#region GUI
Local $hGUI = GUICreate("MyGUI", 500, 500)
 
Global $iLw1 = GUICtrlCreateListView("Column1|Column2", 10, 10, 480, 250, Default, $LVS_EX_CHECKBOXES)
 
 
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
GUISetState(@SW_SHOW, $hGUI)
#endregion
 
For $i = 0 To 9
$item = _GUICtrlListView_InsertItem($iLw1, "Item " & $i)
if $i=1 then
_GUICtrlListView_SetItemChecked($iLW1, $item)
EndIf
Next
 
While GUIGetMsg() <> $GUI_EVENT_CLOSE
    Sleep(10)
WEnd
 
GUIDelete($hGUI)
 
Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    Local $iIDFrom = 0, $iCode = 0, $tNMHDR = 0, $tInfo = 0
 
    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
 
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
 
    Switch $iIDFrom
        Case $iLw1
            Switch $iCode
                Case $LVN_ITEMCHANGING
                    $tInfo = DllStructCreate($tagNMLISTVIEW, $ilParam)

Try this,move the GUIRegisterMsg initialization to after the part where you set the checkbox to checked. This way, the windows message won't fire until AFTER you set it the first time.

#include <WindowsConstants.au3>

#region GUI
Local $hGUI = GUICreate("MyGUI", 500, 500)
Global $iLw1 = GUICtrlCreateListView("Column1|Column2", 10, 10, 480, 250, Default, $LVS_EX_CHECKBOXES)
GUISetState(@SW_SHOW, $hGUI)
#endregion GUI
For $i = 0 To 9
    $item = _GUICtrlListView_InsertItem($iLw1, "Item " & $i)
    If $i = 1 Then
        _GUICtrlListView_SetItemChecked($iLw1, $item)

Next
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
