Inherited class doesn't contain necessary methods

Question

Hi, all!
Here's the problem (channeling Adrian Monk again): I've got a working agent-based model running as a Java app. Everything about the model works except that one of the GUI elements is only displaying 4 of the 6 necessary slider bars that tells the model how to initialize. That GUI element is built into the library that I'm using to construct this java app (RePast code library, you can see it at: http://repast.sourceforge.net/). The GUI class element is RangeWidget, which uses RangePropertyDescriptor to fill it up with the parameters for the slider bars. The RangeWidget in my GUI has space for only 4 of the sliders bars; I've never had to modify a class from its default values. I need some advice. Do I (a) build a personalized RangeWidget class and call it as one of the subservient classes in my main Model.java; (b) import RangeWidget into my main Model.java and explicitly change the values in a separate method next to the RangePropertyDescriptor method; or (c) do something I'm not yet aware of?

Answer 1

Here--I THINK this is the relevant snippets from my MyNewRangeWidget class:
  public MyRangeWidget(int min, int max, int tickSpacing) {
    super(new FlowLayout());
    slider = new JSlider(min, max);
    field = new JTextField(String.valueOf(max).length());
    add(slider);
    add(field);
    this.min = min;
    this.max = max;
    slider.setMajorTickSpacing(tickSpacing);
    slider.setPaintLabels(true);
    slider.setPaintTicks(true);
    slider.addChangeListener(new ChangeListener() {
        public void stateChanged(ChangeEvent evt) {
          if (evt.getSource() == field) {
            // change the value to the fields value
            // check for non-integer value.
            setValue(new Integer(field.getText()));
          } else {
            // change the field to the slider value
            field.setText(String.valueOf(slider.getValue()));
            if (slider.getValueIsAdjusting() == false) fireActionPerformed();
and
  private void setSlider() {
    try {
      Integer i = new Integer(field.getText());
      setValue(i);
    } catch (NumberFormatException ex) {
      Integer i = (Integer)getValue();
      field.setText(i.toString());
      setValue(i);
