Inserts a new row before sibling.
If sibling is null, then the row will be appended to parent’s children.
If parent and sibling are null, then the row will be appended to the toplevel.
If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.
The iter parameter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.tree_store.TreeStore.set or gtk.tree_store.TreeStore.setValue.
An unset gtk.tree_iter.TreeIter to set to the new row
A valid gtk.tree_iter.TreeIter
Deprecated: Use gtk.tree_list_model.TreeListModel instead
