this class implements functions common to all Views.
|
|
82
|
65 |
Instances of View are seldom used, most views in the system inherit
|
|
|
66 |
from this class.
|
|
|
67 |
However, sometimes a view is used to create a dummy view for framing
|
|
|
68 |
or layout purposes.

TODO:
|
|
|
129 |
get rid of relativeOrigin, relativeCorner, originRule, extentRule,
|
|
|
130 |
and insets; replace by a single object which defines the size
|
|
|
131 |
(mhmh - ST-80 seems to call this LayoutFrame ?)
|
|
123
|
132 |
-> be prepared for a change here in the near future and ONLY use
|
|
|
133 |
access methods to those instance variables
|
|
108
|
134 |
|
|
|
135 |
add components (could also call them gadgets or lightweight views)
|
|
|
136 |
- views are expensive in terms of X resources. This would make all
|
|
|
137 |
framing/edge and panel helper views become cheap ST objects, instead
|
|
|
138 |
of views.
