abstract superclass for all kinds of visual components. |
265 | 42 |
This class and its subclasses (currently) exist mostly for |
43 |
ST-80 compatibility - to provide a home for ported PD classes, |
|
44 |
which depend on the VisualComponent hierarchy. |
|
45 |
||
46 |
Notice: |
|
47 |
this class was implemented using protocol information |
|
365 | 48 |
from alpha testers, from reading PD programs and |
49 |
from the Hopkins/Horan book. |
|
265 | 50 |
- it may not be complete or compatible to the corresponding ST-80 class. |
51 |
If you encounter any incompatibilities, please forward a note |
|
52 |
describing the incompatibility verbal (i.e. no code) to the ST/X team. |
|
53 |
This is still being constructed - not yet finished. |
