/**
 * A display-only text field which is not validated and not submitted. This is useful for when you want to display a
 * value from a form's {@link Ext.form.Basic#load loaded data} but do not want to allow the user to edit or submit that
 * value. The value can be optionally {@link #htmlEncode HTML encoded} if it contains HTML markup that you do not want
 * to be rendered.
 *
 * If you have more complex content, or need to include components within the displayed content, also consider using a
 * {@link Ext.form.FieldContainer} instead.
 *
 * Example:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         renderTo: Ext.getBody(),
 *         width: 175,
 *         height: 120,
 *         bodyPadding: 10,
 *         title: 'Final Score',
 *         items: [{
 *             xtype: 'displayfield',
 *             fieldLabel: 'Home',
 *             name: 'home_score',
 *             value: '10'
 *         }, {
 *             xtype: 'displayfield',
 *             fieldLabel: 'Visitor',
 *             name: 'visitor_score',
 *             value: '11'
 *         }],
 *         buttons: [{
 *             text: 'Update'
 *         }]
 *     });
