this class implements functions common to all Views which do not work on / show a model. |
|
62 |
Previously, all of this functionality used to be in the old View class, but has been |
|
63 |
separated into this new SimpleView (which does not know about models) and the new View, which |
|
64 |
does so. |
|
65 |
Instances of SimpleView 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. |

81 |
left <Number> actual left coordinate (pixels) in superview |
|
| 135 | 82 |
extendChanged <Boolean> true if extend changed during setup |
83 |

|
| 151 | 84 |
|
85 |
viewport <Rectangle> my Rectangle in superviews coordinates |
|

|
93 |

94 |
layout <LayoutObject> not yet implemented - will replace the above layout |
|
95 |
variables. |
|
96 |
||
| 135 | 97 |
shown <Boolean> true if visible (false if iconified, unmapped or covered) |
| 151 | 98 |
hiddenOnRealize <Boolean> dont show automatically when superview is realized |

111 |
Class variables: |
|
112 |
||
113 |
Grey <Color> the color grey - its used so often |
|
| 151 | 114 |
ViewSpacing <Number> preferred spacing between views; 1mm |
| 135 | 115 |
|
116 |
CentPoint <Point> 100 @ 100 - its used so often |

|
119 |
||
| 369 | 120 |
ReturnFocusWhenClosingModalBoxes if true, a closing modalBox returns |
121 |
<Boolean> the keyboard focus to the view which was |
|
| 365 | 122 |
active when the box was opened. |
123 |
If false (the default), it is left to |
|
124 |
window manager to assign a new focus. |
|
125 |
If running on olwm/olvwm (which requires an |
|
126 |
explicit click to reassign a focus), it is |
|
127 |
better to turn this on in a private.rc file. |
|

TODO: |
|
142 |
get rid of relativeOrigin, relativeCorner, originRule, extentRule, |
|
143 |
and insets; replace by a single object which defines the size |
|
144 |
(mhmh - ST-80 seems to call this LayoutFrame ?) |
|
145 |
-> be prepared for a change here in the near future and ONLY use |
|
| 151 | 146 |
access methods to get those instance variables' values |
147 |
||
148 |
get rid of 3D level & margin, move it to extra wrappers |
|
149 |
(although this will make view setup more complicated, it will remove |
|
150 |
complexity from the internals of view. Also, it will allow for more |
|
151 |
varieties of borders.) |
|
152 |
||
| 135 | 153 |
add components (could also call them gadgets or lightweight views) |
154 |
- views are expensive in terms of X resources. This would make all |
|
155 |
framing/edge and panel helper views become cheap ST objects, instead |
|
156 |
of views. |

Due to historic reasons, there are 2 mechanisms to resize a view: |
|
411 |
- (old, to be eliminated mechanism) |
|
412 |
based upon info found in |
|
413 |
relativeOrigin / relativeCorner / relativeExtent |
|
414 |
originRule / cornerRule / extentRule |
|
415 |
||
416 |
- (new, will migrate to that one) |
|
417 |
letting a layoutObject compute things |
|
418 |
||
419 |
Actually, the old mechanism is just as powerful, as the new (layoutObject |
|
420 |
based) mechanism; with the help of block=rules, you can compute whatever |
|
421 |
geometry is desired. |
|
422 |
However, having 6 instance variables in every view creates some overhead, |
|
423 |
which can be avoided in most cases (most views are either fixed-size or |
|
424 |
relative-sized). |
|
425 |
Therefore (and also to make porting of ST-80 apps easier), ST/X will migrate |
|
426 |
to use layoutObjects. |
|
427 |
You will not see a difference at the views protocol level, since |
|
428 |
existing interfaces will (silently) create layoutObjects as appropriate. |
|
429 |
However, you should remove all direct accesses to the above mentioned |
|
430 |
instance variables, to be prepared for that change. |
|
431 |
||
432 |
Notice, that a view recomputes its size whenever its superview |
|
433 |
changes size. This is done via: |
|
434 |
sizeChanged |
|
435 |
-> allSubviews: superViewChangedSize |
|
436 |
||
437 |
If the geometry computation as performed in superViewChangedSize |
|
438 |
is not powerful enough for your application, you can either: |
|
439 |
- redefine superViewChangedSize |
|
440 |
- create a special layoutObject which computes a new layout. |

"wait until the receiver visible. |
|
5841 |
In normal applications, you do not need to wait till a view is |
|
5842 |
open - it should do all of its drawing itself when it gets the |
|
5843 |
first expose event. |
|
5844 |
However, if you want to 'manually' draw into the view (for example, |
|
5845 |
in doIt expressions), or subsequent views depend on some state of |
|
5846 |
another view (which is only available once visible), |
|
5847 |
use this to suspend the current process until the receiver is shown. |
|
5848 |
Caveat: |
|
5849 |
we poll here for the view to be shown - we need a semaphore |
|
5850 |
which is raised by the view in order to do it right." |
