[Gambas-user] How do I use TreeView/ColumnView

[ron]

I have a list of entries made in the ColumnView

r-1
  l1-1 'World'
	l2-1 'Water
	l2-2 'Hello'
	l2-3
  l1-2
	l2-1
	l2-2
	l2-3
 l1-3

When I click on r-1 ->  l-1 -> ,l2-2 containing Hello
the _Select is fired if it is the first time and then the _Click

The .key , .Item.Key and .Current.Key give all the same node key
as 'r-1/l1-1/l2-2.'
When I in code do ColumnView1.MoveFirst  they stay the same 
instead of going to 'r-1'
When I do ColumnView1.MoveNext or ColumnView1.MovePrevious 
or any of the other the key stays the same.
Using .MoveTo("r-1") does also nothing. 

If I must use MoveTo(key) to go to the parent how do I get the key of the 
parent, assume .MoveParent returns False so there is a parent.
I know that if the key is build as a path then I can get the key of the parent
and use it in a .MoveTo() if that worked.
But How do I find out the key for 'r-1/l1-1/l-1' with 'Water' as text

Despite the nummers in the keys in the example above, try to see it as 
directories, subdirectories and filename.

I understand it now the .MoveXXXX returns False if it can done 
and True if not posible, or in another way, if they return True means that it 
can't be done like a error.

They show to me as a request "Do I get a error if I do MoveXXX" but how do I 
then actual do the MoveXXX operation?
When I click at item with 'Hello' how do I get the text 'World' in the parent 
node?

The attachment contains my test program.
There is now a TreeView and a ColumnView in the form.
I put the TreeView as last check on it to test if it did the same 
and it does.

ATM I am lost how to use the ColumnView/TreeView
