public final class PuInteger
extends PsObject

Basic integer class with update functionality and panel containing a slider. This class may always be used when a integer instance variable shall be modifiable by a slider in the info panel of its parent class. See the class PjExprOde as a sample application.

Usage demonstrated in a sample class:


        public class PjExprOde {
    protected  PuInteger  m_length;
    public PjExprOde() {
       // Create a new instance of PuInteger and register 'this' as update listener
       // to receive update events whenever user has modified the slider.
       m_length  = new PuInteger("Length", this);
    }
    public void init() {
       // Set default min/max values and increments of slider.
       m_length.setDefBounds(1, 50, 1, 10);
       // Set default value to be assigned in m_length.init() or
       // when slider is reset.
       m_length.setDefValue(15);
       m_length.init();                   // Reset to default values.
    }
    public boolean update(Object event) {
       // Catch update events whenever user has modified slider.
       if (event == m_length) {
          solve(m_length.getValue());     // Do something application depended
          return true;
       }
    }
 }

  - isEnabledConfigButton
```
public boolean isEnabledConfigButton()
```
