/**

 * Assuming the <code>JComponent</code> has the MigLayout set, the label
 * and text field are both left aligned within the <code>JComponent</code>.
 * If the wrap parameter is set to true, MigLayout's "wrap" attribute will be
 * applied to the <code>JTextField</code>, meaning the next component added
 * will appear on the next line.//from ww  w  . j  a va  2s.  co  m
 * (Exception: Will not work if MigLayout's flowy layout constraint is applied,
 * but it is rarely used MigLayout feature and thus not a common concern; however
 * if you have set this layout constraint on your <code>JComponent</code> do not
 * attempt to use the wrap option of this method.)
