[ HasEmitter ]
public virtual signal void row_inserted (TreePath path, TreeIter iter)
This signal is emitted when a new row has been inserted in the model.
Note that the row may still be empty at this point, since it is a common pattern to first insert an empty row, and then fill it with the desired values.
| path |
a `GtkTreePath` identifying the new row |
| iter |
a valid `GtkTreeIter` pointing to the new row |
