You dont have to normally care for all the internals
|
|
35
|
143 |
(they allow many variations though). The typical use is:
|
|
|
144 |
|
|
59
|
145 |
b := Button label:'some logo' in:aView.
|
|
|
146 |
b action:[ .. things to do, when pressed ... ]
|
|
35
|
147 |
|
|
62
|
148 |
for buttons with a string-label,
|
|
|
149 |
and:
|
|
|
150 |
|
|
|
151 |
b := Button form:someImage in:aView.
|
|
|
152 |
b action:[ .. things to do, when pressed ... ]
|
|
|
153 |
|
|
|
154 |
for buttons with a bitmap label.
|
|
|
155 |
|
|
|
156 |
There are many things whaich can be configured in addition;
|
|
|
157 |
for example,
|
|
|
158 |
|
|
59
|
159 |
see 'doc/coding-examples' and 'doc/misc/quick_view_intro.doc' for more variations.
|
|
62
|
160 |
|
|
|
161 |
|
|
|
162 |
To implement fun buttons (for games, show-demos etc.), you can
|
|
|
163 |
access all internal parameters (and not take the viewStyle defaults)
|
|
|
164 |
as in:
|
|
|
165 |
|
|
|
166 |
|b granite light shadow|
|
|
|
167 |
|
|
|
168 |
b := Button label:'isn''t that a nice one ?'.
|
|
|
169 |
granite := Image fromFile:'bitmaps/granite_small.tiff'.
|
|
|
170 |
light := granite lightened.
|
|
|
171 |
shadow := granite darkened.
|
|
|
172 |
b backgroundColor:granite.
|
|
|
173 |
b foregroundColor:Color white.
|
|
|
174 |
b shadowColor:shadow.
|
|
|
175 |
b lightColor:light.
|
|
|
176 |
b onLevel:-3; offLevel:5.
|
|
|
177 |
b extent:(200 @ 50).
|
|
|
178 |
b open
|
|
|
179 |
|
|
|
180 |
However, in your application, you may want to read those bitmaps only once
|
|
|
181 |
during startup and cache them for later reuse in some class variable
|
|
|
182 |
(reading, lightning & darkening of images is a bit slow)
