Recursively expand all branches ox wxTreeCtrl

[Josiah Carlson]

Try the following modifications...

     def OnPopup1(self,event):
         item = self.Tree.GetSelection()
         self.parent.msgbox(self,self.Tree.GetItemText(item),"Kein 
Titel",wxOK)
         #self.Tree.Expand(item)
*       self.ExpandCompleteBranch(self.Tree,item,wxNewId())

     def ExpandCompleteBranch(self,tree,treeitem,cookie):
         self.parent.msgbox(self,"Durchlauf "+str(cookie),"Kein Titel",wxOK)
         if tree.ItemHasChildren(treeitem):
             lastchild = tree.GetLastChild(treeitem)
             tree.Expand(treeitem)
             (child,cookie) = tree.GetFirstChild(treeitem,cookie)
             self.ExpandCompleteBranch(tree,child,cookie+1)
             while child != lastchild:
*               #cookie = cookie + 1
                 (child,cookie) = tree.GetNextChild(treeitem,cookie)
*               self.ExpandCompleteBranch(tree,child,wxNewId())

I use wxNewId() for cookie ids so that all calls will have unique cookie 
ids.  I'm not sure this is technically necessary, but it can't hurt.

Also, by altering the cookie id during the while loop, you are 
destroying the cookie that is necessary to access the remainder of the 
branch.

Give the above (without the '*' at the beginning of the line) a try.
