1. wxEuphoria: get_next_tree_child() Returning 0 For All Child Items

In the following code, get_next_tree_child() is always returning 0. That doesn't seem right.
-- user has selected a category; uninstall all forms in list atom cookie atom indx = get_tree_selection( tree_Templates ) -- get list of all items whose parent is indx integer child_count = get_tree_item_children_count( tree_Templates, indx, 0 ) list = get_first_tree_child( tree_Templates, indx ) cookie = list[2] list = {list[1]} for t=2 to child_count do child = get_next_tree_child( tree_Templates, indx, cookie ) --?child list = append(list, child ) end for
indx is a folder item.
It seems like I'm using those functions properly, but the results aren't what's expected.

These first/next functions are basically iterators. That is, the "next" function gives elements until the list is exhausted, then it returns NULL. The consumer (you) doesn't need to know how many elements are in the list.
Do it like this:
-- user has selected a category; uninstall all forms in list atom indx = get_tree_selection( tree_Templates ) atom item, cookie sequence list = {} -- Euphoria 4.1 supports multiple assignments {item,cookie} = get_first_tree_child( tree_Templates, indx ) while item do list = append( list, item ) item = get_next_tree_child( tree_Templates, indx, cookie ) end while

Doing it that way, get_next_tree_child() still returns 0. Only get_first_tree_child() seems to be working. 
I'm doing a work-around where I store the values of the children as they are created, then using that list instead of the iterator. There's gotta be a bug in there...

I might have fixed this in a more recent build. Are you using my alpha4 build?

Not sure what version I'm using. The include file itself only shows up to 0.17.0.
Can I just drag-n-drop-replace the files in the ZIP you linked over what I currently have installed?

Greg, line 7450 should be this:
c_proc( WX_SHOW_TABART_WINDOW_LIST, {tabArt,window,items,active_idx})
not this
c_proc( WX_SHOW_TABART_WINDOW_LIST, {tabArt,wnd,items,active_idx})
Or change the function definition parameters...

Thanks, Greg! It's working!
