a border holdes the values of a views (or components) border. |
|
13 |
It is (currently) not used by ST/X, but provided as a comatibility hook. |
|
14 |
(... however, ST/X is being rewritten to make use of it soon). |
|
15 |
Notice: |
|
16 |
this class was implemented using protocol information |
|
17 |
from alpha testers, from reading PD programs and |
|
18 |
from the Hopkins/Horan book. |
|
19 |
- it may not be complete or compatible to the corresponding ST-80 class. |
|
20 |
If you encounter any incompatibilities, please forward a note |
|
21 |
describing the incompatibility verbal (i.e. no code) to the ST/X team. |
