check all checkboxes in listview

5 posts in this topic

I have a listview with checkboxes. I have the first one that I would like to, upon checking it, would check all the others.

I tried some things, but nothing worked. I can't figure out how to find out if it is checked or not in the listview.

Also, that brings up the question of "how do I check that the listview check boxes are checked/unchecked"??

Thanks

Hi, here is an example:

#include <GuiConstants.au3>
#include <GuiListView.au3>
Opt("GuiOnEventMode", 1)

Global $IsItemChecked       = False
Global $LV_CHECKED_INDEX    = -1

$GUI = GUICreate("ListView - Check All CheckBoxes Demo", 300, 240)
GUISetOnEvent($GUI_EVENT_CLOSE, "Quit")

$ListView = GUICtrlCreateListView("Column", 20, 10, 260, 220)
_GUICtrlListView_SetExtendedListViewStyle($ListView, $LVS_EX_CHECKBOXES)

GUICtrlCreateListViewItem("Check all Items", $ListView)

For $i = 1 To 10
    GUICtrlCreateListViewItem("Item " & $i, $ListView)
Next

GUICtrlSendMsg($ListView, $LVM_SETCOLUMNWIDTH, 0, -1)
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY_EVENTS")

GUISetState(@SW_SHOW, $GUI)

While 1
    Sleep(10)
    
    If $IsItemChecked Then
        $IsItemChecked = False
        
        $iItemsCount = _GUICtrlListView_GetItemCount($ListView)
        $iCheckedState = _GUICtrlListView_GetItemChecked($ListView, $LV_CHECKED_INDEX)
        
        If $LV_CHECKED_INDEX = 0 Then
            For $i = 1 To $iItemsCount-1
                _GUICtrlListView_SetItemChecked($ListView, $i, $iCheckedState)
            Next
        Else
            If _AllItemsIsChecked($ListView, 1) Then _GUICtrlListView_SetItemChecked($ListView, 0, 1)
            If _AllItemsIsUnChecked($ListView, 1) Then _GUICtrlListView_SetItemChecked($ListView, 0, 0)
        EndIf
    EndIf
WEnd

Func _AllItemsIsChecked($hLV, $iStartIndex=0)
    For $i = $iStartIndex To $iItemsCount-1
        If _GUICtrlListView_GetItemChecked($hLV, $i) = 0 Then Return False
    Next
    
    Return True
EndFunc

Func _AllItemsIsUnChecked($hLV, $iStartIndex=0)
    For $i = $iStartIndex To $iItemsCount-1
        If _GUICtrlListView_GetItemChecked($hLV, $i) = 1 Then Return False
    Next
    
    Return True
EndFunc

Func WM_NOTIFY_EVENTS($hWndGUI, $MsgID, $wParam, $lParam)
    Local $stTagNMHDR = DllStructCreate($tagNMHDR, $lParam)
    If @error Then Return $GUI_RUNDEFMSG
    If $wParam <> $ListView Then Return $GUI_RUNDEFMSG
    
    Local $iCode = DllStructGetData($stTagNMHDR, "Code")
    
    Switch $iCode
        Case $LVN_ITEMCHANGING
            
        Case $LVN_ITEMCHANGED
            
        Case $NM_CLICK, $NM_DBLCLK
            Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
            Local $iIndex = DllStructGetData($tInfo, "Index")
            
            If $iIndex <> -1 Then
                $LV_CHECKED_INDEX = $iIndex
                
                Local $iX = DllStructGetData($tInfo, "X")
                Local $aIconRect = _GUICtrlListView_GetItemRect($ListView, $iIndex, 1)
                
                If $iX < $aIconRect[0] And $iX >= 5 And $iX < 21 Then
                    $IsItemChecked = True
                    
                    If @error Then Return 1
                    Return 0
                EndIf
            EndIf
    EndSwitch
    
    Return $GUI_RUNDEFMSG
EndFunc

Func Quit()
    Exit
EndFunc

Next time better post what you have tried, it's will increes your chances to get help :)

Thanks - this works good.

However, I would like to have only one column in the listview. Is that possible?

Thanks again

Hm... in my example there only one column... if you talking about the seperater after that column, then you need to set width for the column, so the seperater will be equel to the ListView width..

Just replace this:

GUICtrlSendMsg($ListView, $LVM_SETCOLUMNWIDTH, 0, -1)

with this:

GUICtrlSendMsg($ListView, $LVM_SETCOLUMNWIDTH, 0, 256)

256 can be changed, depends on system metrics i think.

Or, you can use Group instead of columns...
