title: How to add padding to JCombobox
body: <p>Imagine a <code>Panel</code> with an editable <code>JCombobox</code> and a <code>JTextfield</code> in vertical order.</p>
  
  <p>The <code>Textfield</code> displays its content with a small padding to the left edge, the <code>Combobox</code> doesn't. </p>
  
  <p>Does anybody know how I can add this padding to the <code>JCombobx</code>? </p>
  
  <p>I've tried setting a renderer but the javadoc says:</p>
  
  <blockquote>
    <p>Sets the renderer that paints the list items and the item selected
    from the list in
    the JComboBox field. The renderer is used if the JComboBox is not
    editable. If it is editable, the editor is used to render and edit
    the selected item.</p>
