RadioButtonControllers redefine the response to a button-click.
|
|
|
39 |
While toggles (i.e. ToggleControllers) change state with every click,
|
|
|
40 |
radioButtons will only do so for an off-to-on transition.
|
|
|
41 |
They will NEVER turn themselfes off with a click.
|
|
|
42 |
To turn a radioButton off, another button in its buttonGroup must
|
|
|
43 |
be turned on and thereby (via the buttonGroup) turn the first button off.
|
|
|
44 |
|
|
|
45 |
You can place both toggles (for 'zero-or-one-on' behavior) or
|
|
|
46 |
radiobuttons (for 'one-on' behavior) into a buttongroup.
