To hide JSpinner with a checbox?

Question

     private SpinnerNumberModel alarmIntervals = new SpinnerNumberModel(DEF_TIME_ALARM, DEF_TIME_ALARM, DEF_TIME_ALARM*QUARTERS_DAY, DEF_TIME_ALARM);
     private JSpinner alarmIntervalSelector;
private JCheckBox alarmOption;
          alarmOption = new JCheckBox(ALARM);
          alarmIntervalSelector = new JSpinner(alarmIntervals);
          alarmIntervalSelector.setVisible(false);
          buttons.add(alarmOption);
          alarmOption.addActionListener(this);
          buttons.add(alarmIntervalSelector);
     public void itemStateChanged(ItemEvent selectedItem){
                        if (selectedItem.getSource() == alarmOption){
                    if (selectedItem.getStateChange() == ItemEvent.SELECTED){
                    alarmIntervalSelector.setVisible(true); frame.pack();
                     } else if (selectedItem.getStateChange() == ItemEvent.DESELECTED){
                    alarmIntervalSelector.setVisible(false); // should disable alarm?
                    frame.pack();
        }These are snippets of the code that seem not to work. Basically I'm trying to hide a component (JSpinner) until the checbox is selected, and vice versa. Yet in the implementation clicking on the checkbox does nothing (should display the jspinner).

Answer 1

Use the Terminal application. The command is "SetFile" (no quotes, and case is important.) You can run the command line, man SetFile, to get instructions on usage. To set the invisible attribute, for example, SetFile -aV fileorfoldername.

Why reward points?(Quoted from Discussions Terms of Use.)
The reward system helps to increase community participation. When a community member gives you (or another member) a reward for providing helpful advice or a solution to their question, your accumulated points will increase your status level within the community.
Members may reward you with 5 points if they deem that your reply is helpful and 10 points if you post a solution to their issue. Likewise, when you mark a reply as Helpful or Solved in your own created topic, you will be awarding the respondent with the same point values.
