/**
+ * A basic hidden field for storing hidden values in forms that need to be passed in the form submit.
+ *
+ * This creates an actual input element with type="submit" in the DOM. While its label is
+ * {@link #hideLabel not rendered} by default, it is still a real component and may be sized according
+ * to its owner container's layout.
+ *
+ * Because of this, in most cases it is more convenient and less problematic to simply
+ * {@link Ext.form.action.Action#params pass hidden parameters} directly when
+ * {@link Ext.form.Basic#submit submitting the form}.
+ *
+ * Example:
+ *
+ *     new Ext.form.Panel({
+ *         title: 'My Form',
+ *         items: [{
+ *             xtype: 'textfield',
+ *             fieldLabel: 'Text Field',
+ *             name: 'text_field',
+ *             value: 'value from text field'
+ *         }, {
+ *             xtype: 'hiddenfield',
+ *             name: 'hidden_field_1',
+ *             value: 'value from hidden field'
+ *         }],
+ *
+ *         buttons: [{
+ *             text: 'Submit',
+ *             handler: function() {
+ *                 this.up('form').getForm().submit({
+ *                     params: {
+ *                         hidden_field_2: 'value from submit call'
+ *                     }
+ *                 });
+ *             }
+ *         }]
+ *     });
+ *
+ * Submitting the above form will result in three values sent to the server:
+ *
+ *     text_field=value+from+text+field&hidden;_field_1=value+from+hidden+field&hidden_field_2=value+from+submit+call
+ *
