1. EuGTK:TreeViiew Parents & Children

Forked from Re: EuGTK:How to Build a TreeView
See the updated function ShowSelection() in the new pasty to see how it works - it obtains the clicked (selected) item, for example, Grumpy Cat, and then obtains the item's parent, adds it to the head of our result, and recurses until there is no parent left. Results:
Mac -> The Woz -> Susan (the other kid) -> Grumpy Cat
Of course, you can format the result however you wish.
Irv, I'm getting a value of -1 for each of these atom vars:
atom fn1 = define_c_func(LIBS[1],"gtk_tree_selection_get_selected",{P,P,P},P) atom fn2 = define_c_func(LIBS[1],"gtk_tree_model_iter_parent",{P,P,P},B) atom fn3 = define_c_func(LIBS[1],"gtk_tree_iter_copy",{P},P)
Can you confirm these should work on Windows?

I can confirm that it won't. Windows isn't smart enough to find the functions when they're located in various dll's.
There is a solution for this windows problem built into EuGTK. Give me an hour or two to get to a windows computer and I'll post it here.

Drat! OK.
I guess I could always install a virtual Linux box to this Windows PC...

EuGTK has a way to work around that: tested on Windows10
---------------------------------- global function ShowSelection() -- ---------------------------------- atom iter = allocate(32), model = allocate(32), parent = allocate(32) object result if gtk_func("gtk_tree_selection_get_selected",{P,P,P},{selection,model,iter}) then result = get(store,"value",iter,1) display(result) -- just shows clicked item; while gtk_func("gtk_tree_model_iter_parent",{P,P,P},{store,parent,iter}) do result = get(store,"value",parent,1) & " -> " & result iter = gtk_func("gtk_tree_iter_copy",{P},{parent}) end while -- look up parents; display(result) -- or, Info(,,result) if you prefer; -- show full path to clicked item; -- e.g: Mac -> The Woz -> Billy (the kid) -> Fido end if return 1 end function
I suppose it would be 'nice' to have this as a function call in EuGTK, but so seldom used, it's probably not a big deal.
