JComboBox holding two values per entry?

[milage]

Hi,

Is it possible to have a JComboBox which holds two values for each entry it lists such as a title and an underlying numeric value for that title? (As with select boxes in HTML)

Likewise, is it possible to do the same for a JList component?

Cheers

Write custom cell renderer
Ex

Alternatively you can use your own ADT as the combo box's value - an object that holds your numeric value and the title. example:

class OwnADT
{
  public int id;
  public String title;

  public OwnADT(id, title)
  {
    this.id = id;
    this.title = title;
  }

  public String toString()
  {
    return this.title;
  }
}

Like that you don't have to change the renderer and can access the numeric data via a direct cast:

int id = ((OwnADT)myComboBox.getSelectedItem()).id;

allow thyself to be the spark that lights the fire
