| 5 - FileDialog | |
| 6 - LoadFileDialog | |
| 7 - SaveFileDialog | |
| 8 | |
| 9 XXX Bugs: | |
| 10 | |
| 11 - The fields are not labeled | |
| 12 - Default doesn't have absolute pathname | |
| 13 - Each FileDialog instance can be used only once | |
| 14 - There is no easy way for an application to add widgets of its own | |
