public class LwGroup

extends LwSwitchManager

This implementation of the switch manager class is used to control state for a set of switching components where only one component can be "on". The library uses the manager to organize radio groups. The example below shows the manager usage for the purpose:

    ...
    LwCheckbox ch1 = new LwCheckbox("Radio 1");
    LwCheckbox ch2 = new LwCheckbox("Radio 3");
    LwCheckbox ch3 = new LwCheckbox("Radio 3");
    LwGroup    group = new LwGroup();
    ch1.setSwitchManager(group);
    ch2.setSwitchManager(group);
    ch3.setSwitchManager(group);
    ...
