TreeView Check Boxes

[gfunk999]

Hey All, going

Is treeview limited to only one selection at a time? I know there's a reason for checkboxes, but i'm failing to come up with a way to check multiple boxes and carry one set of instructions for the selected items. I looked through the forum, and the help files but all examples are for one box selection only; Well at least what I checked.

For example: Select multiple .exe files via checkboxes, and excute all of them with a click of a button.

Code a bit dirty, but that's the best I could come up with based on some forum examples

#include <GuiTreeView.au3>
#include <GUIConstants.au3>


Local $drvgui, $nmsg, $find, $nxtfile, $Drvpath, $gettxt, $readtxt

$DrvPath = "C:\WINDOWS\system32\drivers\"

$drvgui = GUICreate("Drivers", 420, 550)
$treeview = GUICtrlCreateTreeView(10, 10, 400, 500, $TVS_CHECKBOXES)
$button1 = GUICtrlCreateButton("Do Something", 10, 520, 120, 20)

    GUISetState()
        $find = FileFindFirstFile($DrvPath & "*.*")

While 1
    $nxtfile = FileFindNextFile($find)
        If @error Then ExitLoop
            GUICtrlCreateTreeViewitem($nxtfile,$treeview)
WEnd

While 1
    $nmsg = GUIGetMsg()
    Switch $nmsg
        Case $GUI_EVENT_CLOSE
                GUIDelete($drvgui)
                ExitLoop
        Case $button1            
                $gettxt = GUICtrlRead($treeview)
                $readtxt = GUICtrlRead($gettxt, 1)
                MsgBox(0, "", $readtxt)
    EndSwitch
WEnd

Exit

You should be using ControlTreeView(). Use "GetItemCount", then walk the items doing "IsChecked" on each one to assemble a list of checked items. I don't think there is a command to get a collection of all checked items from a treeview in one stroke. This can also be done with the _GuiCtrlTreeView_* functions, but it works the same way.

BTW, since you are only assembling a list of files in one directory, a ListView might be easier to work with than a TreeView anyway. Then you have things like _GUICtrlListView_GetSelectedIndices() available.

If your full script will actually search a recursive path and make a real tree view of the found files, then you will have to make the search for checked items recursive through subitems too.

I'm currently using a tristate treeview for a testing process. What I have done is to create an array that I use to populate the treeview, and then use the following command to determine if it is checked.

It may not be the best example, but it's what works for me as I need to be able to have the information available to the system after a reboot.

For $icc = 0 to Ubound($Aarray)-1
$h = 0
if _GUICtrlTreeView_GetChecked($hTreeView, _GuiCtrlTreeView_FindItem($hTreeView, Aarray[$icc])) = True then $h = 1
$StringExample &= $h
Next

@PsaltyDS

Using ControlTreeView, IsChecked, and GetItemCount worked like a charm. Thank you!

@Kerros

Thank you Kerros i'll keep your advice for future reference.
