12 |
abstract superclass for all kinds of visual components, which |
|
13 |
are containers for some other component. |
|
14 |
This class and its subclasses (currently) exist mostly for |
|
15 |
ST-80 compatibility - to provide a home for ported PD classes, |
|
16 |
which depend on the VisualPart hierarchy. |
|
17 |
||
18 |
Notice: |
|
19 |
this class was implemented using protocol information |
|
365 | 20 |
from alpha testers, from reading PD programs and |
21 |
from the Hopkins/Horan book. |
|
265 | 22 |
- it may not be complete or compatible to the corresponding ST-80 class. |
23 |
If you encounter any incompatibilities, please forward a note |
|
24 |
describing the incompatibility verbal (i.e. no code) to the ST/X team. |
|
25 |
This is still being constructed - not yet finished. |
