a wrapper for a geometric object, which is to be drawn filled. |
|
44 |
This allows any geometric thingy to be used as a filled component in a view. |
|
45 |
||
254 | 46 |
(background info: geometrics are mathematical objects - they do not |
47 |
keep any color or lineStyle attributes. Wrappers add this information |
|
48 |
and can also be used as components of a view) |
|
49 |
||
265 | 50 |
Notice: |
51 |
this class was implemented using protocol information |
|
365 | 52 |
from alpha testers, from reading PD programs and |
53 |
from the Hopkins/Horan book. |
|
265 | 54 |
- it may not be complete or compatible to the corresponding ST-80 class. |
55 |
If you encounter any incompatibilities, please forward a note |
|
56 |
describing the incompatibility verbal (i.e. no code) to the ST/X team. |
