check all checkboxes in treeview

[dickep]

How can I check on item in a treeview and have it check all the other boxes in that treeview?

I had MsCreatoR give me an example using a listview but I don't want any columns in the windows.

Thanks

I had quite a similar problem with a treeview (been using A3LTreeView) - trying to check all checkboxes (alot of checkboxes to check) and it didn't work properly. I've just decided to ask for help in this forum when I saw your post

Lucky me

Thank you

Here is an improved version, OnEvent Mode not used here:

expandcollapse popup

#include <GUIConstants.au3>

Global $iTotal_Items = 10
Global $TVItemsID_Array[$iTotal_Items + 1]

GUICreate("TreeView Check All", 460, 300)

$TreeView = GUICtrlCreateTreeView(20, 20, 420, 260, _
    BitOR($GUI_SS_DEFAULT_TREEVIEW, $TVS_CHECKBOXES), $WS_EX_DLGMODALFRAME + $WS_EX_CLIENTEDGE)

$SelAll_TVItem = GUICtrlCreateTreeViewItem("Select all", $TreeView)
GUICtrlSetColor($SelAll_TVItem, 0xC0C0C0)

For $i = 1 To $iTotal_Items
    $TVItemsID_Array[$i] = GUICtrlCreateTreeViewItem("Item " & $i, $SelAll_TVItem)
Next

GUICtrlSetState($SelAll_TVItem, $GUI_EXPAND)

GUISetState()

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $SelAll_TVItem
            Local $State = $GUI_UNCHECKED
            
            If BitAND(GUICtrlRead($SelAll_TVItem), $GUI_CHECKED) Then
                $State = $GUI_CHECKED
                GUICtrlSetColor($SelAll_TVItem, 0x0)
                GUICtrlSetState($SelAll_TVItem, $GUI_DEFBUTTON + $GUI_CHECKED)
            Else
                GUICtrlSetColor($SelAll_TVItem, 0xC0C0C0)
                GUICtrlSetState($SelAll_TVItem, $GUI_UNCHECKED)
            EndIf

                GUICtrlSetState($TVItemsID_Array[$a], $State)
