Well the current samples\oodialog\controls\TreeView\treeViewCustomDraw.rex
example program reads the lines from a file and has a method makeArgs()
that converts the line into an argument array and then uses sendWith().
You could look at that and do something similar.
do while lines(self~TREE_FILE)
args = self~makeArgs(linein(self~TREE_FILE))
tv~sendWith('add', args)
end
You can also use the insert() method.
If you are inserting an arbitrary item, then I would use insert(). But it
requires you know the parent of where you want to insert the item.
As I recall, you need to be careful using the add() method because it is
semi-dependent on adding the items sequentially from the root.
Without a doubt you can do it without using interpret, just depends on how
much work you want to put into it.
