GUICtrlCreateTreeView event?

[jokke]

Hiya,

Iwe got a treeview and its so damn big i cant use the item-node itself to trigger treeview event.

15 sub categories, where each have about 150+ nodes, how would i be able to trigger a event when clicking on a node?

All help appreciated =)

You might want to post how you are trying to do it now. I have a treeview that dynamically creates items and I've seen it go well over a thousand items with no problems when I click the item. Maybe I'm just sneaking in under a limitation of some kind.

Not my actual script cause that script is way to big to post, but a snippet with the all the basic.

#include <guiconstants.au3>

Dim $item[451], $i = 0

GUICreate("Testing treeview",400,400)
$tree = GUICtrlCreateTreeView(5,5,190,390)
$group1 = GUICtrlCreateTreeViewItem("Sub 1",$tree)
For $x = 0 to 150
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group1)
Next
$group2 = GUICtrlCreateTreeViewItem("Sub 2",$tree)
For $x = 151 to 300
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group2)
Next
$group3 = GUICtrlCreateTreeViewItem("Sub 3",$tree)
For $x = 301 to 450
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group3)
Next

$label = GUICtrlCreateLabel("....",200,5,100,22)
GUISetState()


While 1
    
    $i += 1
    If $i = 450 Then $i = 0
    
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $item[$i] ;hehe not workinbg to well :P
            $item = GUICtrlRead($tree)
            GUICtrlSetData($label,GUICtrlRead($item, 1))
    EndSwitch
WEnd

Guess not!!

This MIGHT do it. I'm just winging it here,

While 1
   $i += 1
   If $i >= 450 Then $I = 1
   $Msg = GUIGetMsg()
   Switch $Msg
      Case $GUI_EVENT_CLOSE
         Exit
      Case $Tree
         $item = GUICtrlRead($Msg)
         GUICtrlSetData($label, GUICtrlRead($msg))
   EndSwitch
Wend

A much better solution would be to use the functions in GUITreeView.au3

Follow the link in my sig for UDF's web-help and go to GUITreeView Management

I came upp with a way of cheating it

expandcollapse popup

#include <guiconstants.au3>

Dim $item[451], $i = 0

GUICreate("Testing treeview",400,400)
$tree = GUICtrlCreateTreeView(5,5,190,390)
$group1 = GUICtrlCreateTreeViewItem("Sub 1",$tree)
For $x = 0 to 9
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group1)
Next
$group2 = GUICtrlCreateTreeViewItem("Sub 2",$tree)
For $x = 151 to 300
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group2)
Next
$group3 = GUICtrlCreateTreeViewItem("Sub 3",$tree)
For $x = 301 to 450
    $item[$x] = GUICtrlCreateTreeViewItem("Item "&$x,$group3)
Next

$label = GUICtrlCreateLabel("....",200,5,100,22)
GUISetState()

$old = ""
While 1
    
    $current = GUICtrlRead(GUICtrlRead($tree),1)
    If $current <> $old Then
        GUICtrlSetData($label,$current)
        $old = $current
    EndIf

    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

Whatever works but I would still take a serious look at the GUITreeView functions in the udf. IIR there is a function that will return the parent node. I just haven't looked in a while.
