Hi,
Is there a way to loop through all the items in a TreeView?
Is there a way to loop through all the items below a given TreeView Node?
Is there a way to loop through just the child items of a given TreeView Node?
I can't see a way to 'get' the TreeView item count or a TreeView item path by index like with a ListView.
Hoping I don't need to maintain an additional Skip of items...
Thanks

You can only deal in one way with treeviews. You can iterate over all treeview entries and get their paths:
int cnt = 0; string s; for s in dbeTreeview do { print (cnt++) ": " s "\n" }
Treeviews separate their items by slashes (therefore you cannot add items with slashes in a treeview). From that it is pretty clear how to answer the rest of the questions. To find the child nodes you search for items that start with the same path. To find items below you will search for all items that come after the respective item. Well and to count the items you probably need to count them.
If performance is an issue I would suggest to write a library with an ExtendedTreeview, which will store the meta information for you and provide additional information functions.
Hope that helps, Regards, Mathias

"DBE is neither a list nor a listView"
Maybe it's a my DOORS version. I am using DOORS 9.3.0.2

Thanks, I don't see that for loop in the help (no surprise there though) and when I try it I get the error:
"DBE is neither a list nor a listView"

Ouch! Mental note: always double check what you are saying ;-) It seems you really cannot iterate over the items in the treeview and you indeed need to keep the item path in a skip list. Sorry for that. Regards, Mathias
