an icon and a string, side by side. |
|
| 178 | 41 |
Usable as list entries in a listView (a fileList), as |
| 179 | 42 |
popUpMenuItems or as Label/Button image. |
| 172 | 43 |
|
44 |
This is an example class - currently not used by the system. |
|
45 |
||
| 179 | 46 |
Notice: |
47 |
This is different from ST-80's LabelAndIcon class, which |
|
48 |
inherits from Label. Therefore, things may change in the future. |
