Generate Treeview Function

4 posts in this topic

Hi, maybe my question is stupid, but i don't find the answer...

I want to put my treeview creation in a function.

I wrote the following code:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <TreeViewConstants.au3>
#include <StaticConstants.au3>
#Include <GuiTreeView.au3>


GUICreate("AD TreeView", 400, 400)

$treeviewID    = CreateADTree (25, 25, 300, 300, BitOr($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)
$treeview = GUICtrlGetHandle ($treeviewID)

$infobutton     = GUICtrlCreateButton("Info", 25, 350, 70, 20, 0)
$cancelbutton   = GUICtrlCreateButton("Cancel", 125, 350, 70, 20, 0)


GUISetState ()
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $cancelbutton Or $msg = $GUI_EVENT_CLOSE
            ExitLoop
    
    
        Case $msg = $infobutton
            $item = GUICtrlRead($treeview)   ; Get the controlID of the current selected treeview item
            
            If $item = 0 Then
                MsgBox(64, "TreeView Demo", "No item currently selected")
            Else
                _GUICtrlTreeView_SelectItem($treeview, $item)
            ;MsgBox(4160, "Information", "Parent Handle: " & _GUICtrlTreeView_GetParentHandle($treeview, $item)) 
            ;MsgBox(4160, "Information", "Parent ID: " & _GUICtrlTreeView_GetParentParam($treeview, $item))
                $ParentID = _GUICtrlTreeView_GetParentParam($treeview, $item)
                $ParentText = GUICtrlRead($ParentID, 1)
                
            ;_GUICtrlTreeView_SelectItem($treeview, _GUICtrlTreeView_GetParentHandle($treeview, $item))
                
                $text = GUICtrlRead($item, 1); Get the text of the treeview item
                If $text == "" Then
                    MsgBox(16, "Error", "Error while retrieving infos about item")
                Else
                    MsgBox(64, "TreeView Demo", "Parent Text is : "& $ParentText &" and Current item selected is: " & $text)
                EndIf
            EndIf
            

            
      EndSelect
WEnd

GUIDelete()
Exit


Func CreateADTree ($intLeft, $intTop, $intWidth, $intHeight, $intStyle, $intExStyle )
    Local $LocalTreeview
    
    $LocalTreeview  = GUICtrlCreateTreeView($intLeft, $intTop, $intWidth, $intHeight, $intStyle, $intExStyle)
    
    $hImage = _GUIImageList_Create(16, 16, 5, 3)
    $hFolderImage = _GUIImageList_AddIcon($hImage, "shell32.dll", 4)
    _GUICtrlTreeView_SetNormalImageList($LocalTreeview, $hImage)    
    
    _GUICtrlTreeView_BeginUpdate($LocalTreeview)
    $RootNode = _GUICtrlTreeView_Add($LocalTreeview, 0, "ROOT NODE", $hFolderImage, $hFolderImage)
        _GUICtrlTreeView_AddChild($LocalTreeview, $RootNode, "DO 1",$hFolderImage, $hFolderImage)
        
        $DO2 = _GUICtrlTreeView_AddChild($LocalTreeview, $RootNode, "DO 2", $hFolderImage, $hFolderImage)
            _GUICtrlTreeView_AddChild($LocalTreeview, $DO2, "Sub 1",$hFolderImage,$hFolderImage)
            _GUICtrlTreeView_AddChild($LocalTreeview, $DO2, "Sub 2",$hFolderImage,$hFolderImage)
            _GUICtrlTreeView_AddChild($LocalTreeview, $DO2, "Sub 3",$hFolderImage,$hFolderImage)
            _GUICtrlTreeView_AddChild($LocalTreeview, $DO2, "Sub 4",$hFolderImage,$hFolderImage)
        
        _GUICtrlTreeView_AddChild($LocalTreeview, $RootNode, "DO 3",$hFolderImage, $hFolderImage)
        _GUICtrlTreeView_AddChild($LocalTreeview, $RootNode, "DO 4",$hFolderImage, $hFolderImage)
    
    _GUICtrlTreeView_EndUpdate($LocalTreeview)
    
    Return $LocalTreeview
EndFunc

Well, my treeview is created, but i cannot get the selected item!!

Have you some function to get the texte/name of the selected node ? I'm not sure i'm using the best way...

Thank you very much!!

_GUICtrlTreeView_GetSelection

This will get you the handle to the current item. You can then use other functions to get the text and other information (like the next sibling or previous sibling, etc.)
