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
|
|
|
20 |
from alpha testers and from the Hopkins/Horan book.
|
|
|
21 |
- it may not be complete or compatible to the corresponding ST-80 class.
|
|
|
22 |
If you encounter any incompatibilities, please forward a note
|
|
|
23 |
describing the incompatibility verbal (i.e. no code) to the ST/X team.
|
|
|
24 |
This is still being constructed - not yet finished.
