Hi,
I am trying to create a dialog with a gtk.TreeView() with a
gtk.ListStore() model. I don't know until run time how many columns
will be needed. I have managed to create the TreeView but I haven't
worked out how to populate it.
Any help appreciated.
Regards Neil.
Hi Neil,
I think your problem steams from the line
dialog._model = gtk.ListStore(object)
Which I think should be more like
dialog._model = gtk.ListStore(str,str,str)
However this does not give you the dynamic nature you desire.
I don't know the limits of column expansion/contraction you require for
your problem, .. but I see in your code you want to limit it to 20
(are they always strings?, or all columns the same type?)
I would create a listStore with 20 str as arguments.
I would then create the treeview with as many columns needed for the
problem at hand
Attached you will see a modified prog that works for me, I limited the
columns to 7, each time you press the dialog button, a list is
dynamically generated with a random number of columns.
Assumptions:
the list is always strings.
length of list correlates to number of colomns to view.
Don't know if this has been helpful?

Hi Steve,
Thanks, that does do what I want. :)
After posting I found out that, that line was the trouble, but I
couldn't find a decent way of handling the problem. I didn't realise
you could specify more types when creating the gtk.ListStore than you
had intentions of using.
I think it would be handy to be able to use a list or truple to
specify the types as well.
Regards Neil.
