This class provides PopUpMenu functionality; Actually, this class
|
|
|
53 |
only provides the popup and shadow functionality and wraps another
|
|
|
54 |
view, which is the actual menu-list (usually an instance of MenuView).
|
|
|
55 |
|
|
|
56 |
PopUpMenus are usually created with a list of labels, selectors and a
|
|
|
57 |
receivier. Once activated, the specified receiver will be sent a
|
|
|
58 |
'selector'-message.

|
64 |
Examples:
|
|
|
65 |
|
|
59
|
66 |
|p|
|
|
|
67 |
p := PopUpMenu
|
|
|
68 |
labels:#('foo'
|
|
|
69 |
'bar'
|
|
|
70 |
'baz')
|
|
|
71 |
selectors:#(
|
|
|
72 |
#foo
|
|
|
73 |
#bar
|
|
|
74 |
#baz)
|
|
|
75 |
receiver:nil.
|
|
|
76 |
p showAtPointer
|
|
38
|
77 |
|
|
|
78 |
|
|
|
79 |
sometimes, you want to specify both selectors and some arguments
|
|
|
80 |
to be sent; this is done by:
|
|
|
81 |
|
|
59
|
82 |
|p|
|
|
|
83 |
p := PopUpMenu
|
|
|
84 |
labels:#('foo' 'bar' 'baz')
|
|
|
85 |
selectors:#(#foo: #bar: #foo:)
|
|
|
86 |
args:#(1 2 3)
|
|
|
87 |
receiver:nil.
|
|
|
88 |
p showAtPointer
|
|
38
|
89 |
|
|
|
90 |
or, the same selector but different arguments:
|
|
|
91 |
|
|
59
|
92 |
|p|
|
|
|
93 |
p := PopUpMenu
|
|
|
94 |
labels:#('foo' 'bar' 'baz')
|
|
|
95 |
selectors:#foo:
|
|
|
96 |
args:#(1 2 3)
|
|
|
97 |
receiver:nil.
|
|
|
98 |
p showAtPointer
|
|
38
|
99 |
|
|
|
100 |
Normally, you do not show the menu explicitely, but install
|
|
|
101 |
it as a middleButtonMenu of some view. (Views button-event handler
|
|
|
102 |
will show it when the button is pressed ...)
|
|
|
103 |
|
|
59
|
104 |
|v m|
|
|
38
|
105 |
|
|
59
|
106 |
v := View new.
|
|
|
107 |
m := PopUpMenu
|
|
|
108 |
labels:#('lower'
|
|
|
109 |
'raise'
|
|
|
110 |
'-'
|
|
|
111 |
'destroy')
|
|
|
112 |
selectors:#(#lower #raise nil #destroy)
|
|
|
113 |
receiver:v.
|
|
|
114 |
v middleButtonMenu:m.
|
|
|
115 |
v open
|
|
38
|
116 |
|
|
|
117 |
It is also possible, to add check-mark entries, with an entry string
|
|
|
118 |
starting with the special sequence '\c' (for check-mark). The value
|
|
|
119 |
passed will be the truth-state of the check-mark.
|
|
|
120 |
|
|
59
|
121 |
|m v|
|
|
38
|
122 |
|
|
59
|
123 |
v := View new.
|
|
|
124 |
m := PopUpMenu
|
|
|
125 |
labels:#('\c foo'
|
|
|
126 |
'\c bar')
|
|
|
127 |
selectors:#(#value: #value:)
|
|
|
128 |
receiver:[:v | Transcript show:'arg: '; showCr:v].
|
|
|
129 |
v middleButtonMenu:m.
|
|
|
130 |
v open
|
|
38
|
131 |
|
|
|
132 |
|
|
|
133 |
Finally, you can wrap other views into a popup menu (for example,
|
|
|
134 |
to implement menus with icons or other components).
|
|
|
135 |
The view should respond to some messages sent from here (for
|
|
|
136 |
example: #hideSubmenus, #deselectWithoutRedraw and others).
|
|
|
137 |
Currently there is only one class in the system, which can be used
|
|
|
138 |
this way (PatternMenu in the DrawTool demo):
|
|
|
139 |
|
|
59
|
140 |
|v p|
|
|
38
|
141 |
|
|
59
|
142 |
v := View new.
|
|
|
143 |
p := PatternMenu new.
|
|
|
144 |
p patterns:(Array with:Color red
|
|
|
145 |
with:Color green
|
|
|
146 |
with:Color blue).
|
|
|
147 |
v middleButtonMenu:(PopUpMenu forMenu:p).
|
|
|
148 |
v open
|
|
38
|
149 |
|
|
|
150 |
or try:
|
|
|
151 |
|
|
59
|
152 |
|v p|
|
|
38
|
153 |
|
|
59
|
154 |
v := View new.
|
|
|
155 |
p := PatternMenu new.
|
|
|
156 |
p patterns:(Array with:Color red
|
|
|
157 |
with:Color green
|
|
|
158 |
with:Color blue).
|
|
|
159 |
p selectors:#value:.
|
|
|
160 |
p receiver:[:val | v viewBackground:val. v clear].
|
|
|
161 |
p args:(Array with:Color red
|
|
|
162 |
with:Color green
|
|
|
163 |
with:Color blue).
|
|
|
164 |
v middleButtonMenu:(PopUpMenu forMenu:p).
|
|
|
165 |
v open
|
|
38
|
166 |
|
|
|
167 |
|
|
|
168 |
ST-80 style:
|
|
|
169 |
|
|
|
170 |
The above menus all did some message send on selection; it is
|
|
|
171 |
also possible, to use Smalltalk-80 style menus (which return some value
|
|
|
172 |
from their startup method):
|
|
|
173 |
|
|
59
|
174 |
|m selection|
|
|
38
|
175 |
|
|
59
|
176 |
m := PopUpMenu
|
|
|
177 |
labels:#('one' 'two' 'three').
|
|
|
178 |
selection := m startUp.
|
|
|
179 |
Transcript show:'the selection was: '; showCr:selection
|
|
38
|
180 |
|
|
|
181 |
startUp will return the entries index, or 0 if there was no selection.
|
|
|
182 |
You can also specify an array of values to be returned instead of the
|
|
|
183 |
index:
|
|
|
184 |
|
|
59
|
185 |
|m selection|
|
|
38
|
186 |
|
|
59
|
187 |
m := PopUpMenu
|
|
|
188 |
labels:#('one' 'two' 'three')
|
|
|
189 |
values:#(10 20 30).
|
|
|
190 |
selection := m startUp.
|
|
|
191 |
Transcript show:'the value was: '; showCr:selection
|
|
38
|
192 |
|
|
|
193 |
In ST/X style menus, separating lines between entries are created
|
|
|
194 |
by a '-'-string as its label text (and corresponding nil-entries in the
|
|
|
195 |
selectors- and args-arrays).
|
|
|
196 |
In ST-80, you have to pass the indices of the lines in an extra array:
|
|
|
197 |
|
|
59
|
198 |
|m selection|
|
|
38
|
199 |
|
|
59
|
200 |
m := PopUpMenu
|
|
|
201 |
labels:#('one' 'two' 'three' 'four' 'five')
|
|
|
202 |
lines:#(2 4).
|
|
|
203 |
selection := m startUp.
|
|
|
204 |
Transcript show:'the value was: '; showCr:selection
|
|
38
|
205 |
|
|
|
206 |
or:
|
|
59
|
207 |
|m selection|
|
|
38
|
208 |
|
|
59
|
209 |
m := PopUpMenu
|
|
|
210 |
labels:#('one' 'two' 'three')
|
|
|
211 |
lines:#(2)
|
|
|
212 |
values:#(10 20 30).
|
|
|
213 |
selection := m startUp.
|
|
|
214 |
Transcript show:'the value was: '; showCr:selection
|
|
38
|
215 |
|
|
|
216 |
