Hi, ich habe Probleme mit dem Treegadget, ich will bei einem auf einen Eintrag alle höherliegenden Parents ausgeben lassen..

In der alten version von PB war das ganze ja kein problem, da hab ich im Code Archive folgenden Code gefunden:

Code: Alles auswählen

  
[...]
If GetGadgetState(#Path) <> -1
        CurrentItem.l = GetGadgetState(#Path)
        CurrentText.s = GetGadgetItemText(#Path, CurrentItem, 0)
  
        ItemToWalk.l = CurrentItem
        FullPath.s   = CurrentText.s
  
        Repeat
          hItem.l        = GadgetItemID(#Path, ItemToWalk)
          hParent.l      = SendMessage_(GadgetID(#Path), #TVM_GETNEXTITEM, #TVGN_PARENT, hItem)
          ParentNumber.l = TreeGadgetItemNumber(#Path, hParent)
          ParentText.s   = GetGadgetItemText(#Path, ParentNumber, 0)
          FullPath.s     = ParentText + "\" + FullPath
          ItemToWalk     = ParentNumber
        Until ItemToWalk = -1
  
        If Left(FullPath.s, 1) = "\"
          ;FullPath.s = Mid(FullPath.s, 2, Len(FullPath.s) - 1)
        EndIf
        ;Debug "Line:   " + Str()
        ;Debug "Child:  " + CurrentText
        FullPath.s=Right(FullPath.s,Len(FullPath.s)-1)
        Debug "PATH: "+FullPath.s
     EndIf   
[...]

So, aber leider gibt es ja in der Version 4 von Purebasic nicht mehr den Befehl TreeGadgetItemNumber(#Gadget, hParent). Welchen PB oder API befehl muss ich verwenden damit das ganze wieder Funktioniert?

Danke Deluxe0321
