* by doubleclicking. A list model which contains the file in a column
* specified by fileNameColumn should be set using setFileModel().
*
* Additionally, standard creator actions can be registered:
* Undo/redo will be set up to work with the description editor.
* Submit will be set up to be enabled according to checkstate.
* Diff will be set up to trigger diffSelected().
*
* Note that the actions are connected by signals; in the rare event that there
* are several instances of the SubmitEditorWidget belonging to the same
* context active, the actions must be registered/unregistered in the editor
* change event.
* Care should be taken to ensure the widget is deleted properly when the
* editor closes. */
