title: Adding items to a JComboBox
body: <p>I use a combo box on panel and as I know we can add items with the text only</p>
  
  <pre><code>    comboBox.addItem('item text');
  </code></pre>
  
  <p>But some times I need to use some value of the item and item text like in html select:</p>
  
  <pre><code>    &lt;select&gt;&lt;option value="item_value"&gt;Item Text&lt;/option&gt;&lt;/select&gt;
  </code></pre>
  
  <p>Is there any way to set both value and title in combo box item?</p>
  
  <p>For now I use a hash to solve this issue.</p>
