public class CheckboxGroup extends Object implements Serializable
CheckboxGroup
class is used to group together
a set of Checkbox
buttons.
Exactly one check box button in a CheckboxGroup
can
be in the "on" state at any given time. Pushing any
button sets its state to "on" and forces any other button that
is in the "on" state into the "off" state.
The following code example produces a new check box group, with three check boxes:
setLayout(new GridLayout(3, 1)); CheckboxGroup cbg = new CheckboxGroup(); add(new Checkbox("one", cbg, true)); add(new Checkbox("two", cbg, false)); add(new Checkbox("three", cbg, false));
This image depicts the check box group created by this example:
