Position is an in-out paramter. After the signal emission is finished, it should point after the newly inserted text. The default handler for this signal will normally be responsible for inserting the text, so by overriding this method and either calling or not calling the parent class method, it is possible to modify the inserted text, or prevent it from being inserted entirely. </td>
