Prepends a new row to this.
Use [class@Gtk.TreeListModel] instead
If parent
is non-null, then it will prepend the new row before the first child of
parent
, otherwise it will prepend a row to the top level. 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 @set
or set_value.
