RadioButtonGroups control the interaction between RadioButtons
|
|
|
54 |
turning off other button(s) when one of the group is pressed.
|
|
63
|
55 |
To group some buttons (and have one-on behavior) use:
|
|
|
56 |
|
|
|
57 |
|g|
|
|
|
58 |
|
|
|
59 |
g := RadioButtonGroup new.
|
|
|
60 |
...
|
|
|
61 |
b1 := RadioButton label:....
|
|
|
62 |
g add:b1
|
|
|
63 |
...
|
|
|
64 |
b2 := RadioButton label:....
|
|
|
65 |
g add:b2
|
|
|
66 |
...
|
|
116
|
67 |
|
|
|
68 |
example (using Toggles for 'at most one-on behavior'):
|
|
|
69 |
|
|
|
70 |
|top panel toggle b g|
|
|
|
71 |
|
|
|
72 |
top := StandardSystemView new.
|
|
|
73 |
panel := HorizontalPanelView origin:0.0@0.0 corner:1.0@1.0 in:top.
|
|
|
74 |
g := RadioButtonGroup new.
|
|
|
75 |
b := Toggle label:'one' in:panel.
|
|
|
76 |
g add:b.
|
|
|
77 |
b := Toggle label:'two' in:panel.
|
|
|
78 |

|

|
|
