B4J Question List folder/sub folder to treeview

[dgoss]

I looked but could not find anything here so I ask the question.

This is what I can do with treeview:-
list folders
expand and list sub folders

But when collapse folder and re-open it I get double listing of sub folders, I don't know how to refresh treeview without having to list all folders again.

Pls be patient with me for I know not what I am doing

Can you post some code? Are you adding items in the ExpandedChanged event?

posted small test project

Test whether the TreeItem was already filled or not:

If ti.Children.Size = 0 Then
 'fill it
End If

Why don't you use FileChooser or DirectoryChooser?
