Buttons are Labels which do something when pressed/released.
|
|
113
|
70 |
Since they inherit from Label, read the documentation on Labels to
|
|
|
71 |
see how color, layout, font, image or labelString are changed.
|
|
|
72 |
|
|
|
73 |
Actionblock operation:
|
|
|
74 |
button has an actionBlock (actually, it has two: a pressAction and
|
|
|
75 |
a releaseAction) which are evaluated.
|
|
|
76 |
The user of a button can define these actions via the #action,
|
|
|
77 |
#pressAction or #releaseAction messages.
|
|
|
78 |
|
|
|
79 |
Model-View interaction:
|
|
118
|
80 |
buttons with a model and a labelMsg react to changes of the aspect
|
|
|
81 |
and perform a labelMsg-message on the model to aquire a new labelString.
|
|
113
|
82 |
The model is should send 'self changed:<aspect>' if it wants the label to
|
|
118
|
83 |
change and return a string from the labelSymbol-message.
|
|
|
84 |
By default, the labelMsg is nil, therefore no update of the label is done.
|
|
|
85 |
(this behavior is inherited from label, see documentation there)
|
|
|
86 |
|
|
|
87 |
When pressed, the button sends a <change> message to the model.
|
|
|
88 |
If the changeMsg is for a one-argument message, the current
|
|
113
|
89 |
press-state is passed as argument (i.e. true if pressed, false if released).
|
|
118
|
90 |
By default, the change-Message is #value: (for ST-80 compatibility).
|
|
113
|
91 |
|
|
|
92 |
button model:aModel.
|
|
|
93 |
button aspect:aspectSymbol.
|
|
|
94 |
button change:changeSymbol.
|
|
|
95 |
|
|
|
96 |
model sends #changed:aspectSymbol
|
|
|
97 |
---> button will redraw its label from value of model>>aspectSymbol
|
|
|
98 |
|
|
|
99 |
button changes state:
|
|
|
100 |
---> button sends changeSymbolSymbol / changeSymbol:state
|
|
|
101 |
|
|
118
|
102 |
By default (as inherited), the labelMsg is nil; therefore, buttons
|
|
|
103 |
do not try to aquire a new labelString from the model.
|
|
|
104 |
If you want this behavior, you must set labelMsg and aspectMsg
|
|
|
105 |
as appropriate.

You dont have to normally care for all the internals
|
|
35
|
165 |
(they allow many variations though). The typical use is:
|
|
|
166 |
|
|
59
|
167 |
b := Button label:'some logo' in:aView.
|
|
|
168 |
b action:[ .. things to do, when pressed ... ]
|
|
35
|
169 |
|
|
62
|
170 |
for buttons with a string-label,
|
|
|
171 |
and:
|
|
|
172 |
|
|
118
|
173 |
b := Button label:someImage in:aView.
|
|
62
|
174 |
b action:[ .. things to do, when pressed ... ]
|
|
|
175 |
|
|
|
176 |
for buttons with a bitmap label.
|
|
|
177 |
|
|
118
|
178 |
|
|
88
|
179 |
Although you can specify a lot in a button,
|
|
|
180 |
use the default in most applications.
|
|
|
181 |
As you specify more things in your program,
|
|
|
182 |
the styleSheet settings are more and more ignored.
|
|
|
183 |
Also, even though it might look fancy, colorful
|
|
|
184 |
button panels are usually not a good GUI design;
|
|
|
185 |
they will attract the users attention - possibly to things
|
|
|
186 |
which are not worth it.
|
|
130
|
187 |
Finally, if you use fancy colors, always thing of those without
|
|
|
188 |
color displays - the styleSheet allows those people to adjust things,
|
|
|
189 |
while hard-coded colors cannot be fixed without changing the code.
|
|
88
|
190 |
|
|

191 |

|
|
|
192 |

|

To implement fun buttons (for games, show-demos etc.), you can

access all internal parameters (and not take the viewStyle defaults)
|
|

as in:
|
|
|
376 |

|
|

However, in your application, you may want to read those bitmaps only once
|
|
|
394 |
during startup and cache them for later reuse in some class variable
|
|
|
395 |
(reading, lightning & darkening of images is a bit slow)

ST/X Buttons allow simulation of the ST-80 MVC way of interacting.
|
|
|
399 |
To do so, instead (or in addition) to defining actionBlocks, set the
|
|
127
|
400 |
buttons model to have this be informed (in addition):
|
|
118
|
401 |
|
|
|
402 |
Model-View interaction (ST-80 style):
|
|
|
403 |
(have a look at the models values in the inspector, as the toggles change)
|
|
|
404 |
|
|
|
405 |

Using a PluggableAdaptor (ST-80 style):
|
|

427 |
(notice, that this is almost what ST/X buttons did originally,
|
|
127
|
428 |
therefore, you may want use actionBlocks right away ...)
