Re: GtkTreeView - drag & drop

[John M Collins <jmc xisl com>]

Thanks for your help I'd completely missed gtk_tree_view_set_reorderable
and it does what I wanted apart from the ctrl to copy - perhaps I'll do
that with a "duplicate selected item" button and then have the user use
drag and drop to put the newly created item where he/she wants it.

Now wrestling with GtkCellRendererCombo and GtkCellRendererSpin if
anyone can give me a few tips in their usage I'd be grateful also.
