this class implements functions common to all Views which do not work on / show a model. |
|
66 |
Previously, all of this functionality used to be in the old View class, but has been |
|
67 |
separated into this new SimpleView (which does not know about models) and the new View, which |
|
68 |
does so. |
|
69 |
Instances of SimpleView are seldom used, most views in the system inherit |
|
70 |
from this class. |
|
71 |
However, sometimes a view is used to create a dummy view for framing |
|
72 |
or layout purposes. |

TODO: |
|
138 |
get rid of relativeOrigin, relativeCorner, originRule, extentRule, |
|
139 |
and insets; replace by a single object which defines the size |
|
140 |
(mhmh - ST-80 seems to call this LayoutFrame ?) |
|
141 |
-> be prepared for a change here in the near future and ONLY use |
|
| 151 | 142 |
access methods to get those instance variables' values |
143 |
||
144 |
get rid of 3D level & margin, move it to extra wrappers |
|
145 |
(although this will make view setup more complicated, it will remove |
|
146 |
complexity from the internals of view. Also, it will allow for more |
|
147 |
varieties of borders.) |
|
148 |
||
| 135 | 149 |
add components (could also call them gadgets or lightweight views) |
150 |
- views are expensive in terms of X resources. This would make all |
|
151 |
framing/edge and panel helper views become cheap ST objects, instead |
|
152 |
of views. |

layoutComputation |
|
157 |
" |
|
158 |
Due to historic reasons, there are 2 mechanisms to resize a view: |
|
159 |
- (old, to be eliminated mechanism) |
|
160 |
based upon info found in |
|
161 |
relativeOrigin / relativeCorner / relativeExtent |
|
162 |
originRule / cornerRule / extentRule |
|
163 |
||
164 |
- (new, will migrate to that one) |
|
165 |
letting a layoutObject compute things |
|
166 |
||
167 |
Actually, the old mechanism is just as powerful, as the new (layoutObject |
|
168 |
based) mechanism; with the help of block=rules, you can compute whatever |
|
169 |
geometry is desired. |
|
170 |
However, having 6 instance variables in every view creates some overhead, |
|
171 |
which can be avoided in most cases (most views are either fixed-size or |
|
172 |
relative-sized). |
|
173 |
Therefore (and also to make porting of ST-80 apps easier), ST/X will migrate |
|
174 |
to use layoutObjects. |
|
175 |
You will not see a difference at the views protocol level, since |
|
176 |
existing interfaces will (silently) create layoutObjects as appropriate. |
|
177 |
However, you should remove all direct accesses to the above mentioned |
|
178 |
instance variables, to be prepared for that change. |
|
179 |
||
180 |
Notice, that a view recomputes its size whenever its superview |
|
181 |
changes size. This is done via: |
|
182 |
sizeChanged |
|
183 |
-> allSubviews: superViewChangedSize |
|
184 |
||
185 |
If the geometry computation as performed in superViewChangedSize |
|
186 |
is not powerful enough for your application, you can either: |
|
187 |
- redefine superViewChangedSize |
|
188 |
- create a special layoutObject which computes a new layout. |

In normal applications, you do not need to wait till the view is |

open - it should do all of its drawing itself when it gets the |

first expose event. |
