Changing the appearance of TreeView ListBox

[#1]

As per default, QlikView sets up TreeViews like so :

PARENT

     |______CHILD 1

     |______CHILD 2

     |______CHILD 3

     |______CHILD 4

How is it possible to Display the very same thing displaying the full child name, like so:

PARENT

     |______PARENT CHILD 1

     |______PARENT CHILD 2

     |______PARENT CHILD 3

     |______PARENT CHILD 4

Any help would be highly appreciated.

Thanks a lot in advance,

Seb

Of course I could solve this by selecting a "TreeView-Friendly" name into my model as an additional dimension and use standard TreeView view with a specified separator char (here : #):

Name     TreeViewName

Parent     Parent

Child1     Parent#Child1

But What I mean is a ListBox-only implementation, a way to parameterize the checkbox functionality further than naming the separator char...
