| 21 | * @brief User management for Disobedience |
| 22 | * |
| 23 | * The user management window contains: |
| 24 | * - a list of all the users |
| 25 | * - an add button |
| 26 | * - a delete button |
| 27 | * - a user details panel |
| 28 | * - an apply button |
| 29 | * |
| 30 | * When you select a user that user's details are displayed to the right of the |
| 31 | * list. Hit the Apply button and any changes are applied. |
| 32 | * |
| 33 | * When you select 'add' a new empty set of details are displayed to be edited. |
| 34 | * Again Apply will commit them. |
| 35 | * |
| 36 | * TODO: it would be really nice if the Username entry could be removed and new |
| 37 | * user names entered in the list, rather off in the details panel. This may |
| 38 | * be possible with a sufficiently clever GtkCellRenderer. |
