- * @class Ext.form.FormPanel
- * @extends Ext.Panel
- * <p>Standard form container.</p>
- *
- * <p><b><u>Layout</u></b></p>
- * <p>By default, FormPanel is configured with <tt>layout:'form'</tt> to use an {@link Ext.layout.FormLayout}
- * layout manager, which styles and renders fields and labels correctly. When nesting additional Containers
- * within a FormPanel, you should ensure that any descendant Containers which host input Fields use the
- * {@link Ext.layout.FormLayout} layout manager.</p>
- *
- * <p><b><u>BasicForm</u></b></p>
- * <p>Although <b>not listed</b> as configuration options of FormPanel, the FormPanel class accepts all
- * of the config options required to configure its internal {@link Ext.form.BasicForm} for:
- * <div class="mdetail-params"><ul>
- * <li>{@link Ext.form.BasicForm#fileUpload file uploads}</li>
- * <li>functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form</li>
- * </ul></div>
- *
- * <p><b>Note</b>: If subclassing FormPanel, any configuration options for the BasicForm must be applied to
- * the <tt><b>initialConfig</b></tt> property of the FormPanel. Applying {@link Ext.form.BasicForm BasicForm}
- * configuration settings to <b><tt>this</tt></b> will <b>not</b> affect the BasicForm's configuration.</p>
- *
- * <p><b><u>Form Validation</u></b></p>
- * <p>For information on form validation see the following:</p>
- * <div class="mdetail-params"><ul>
- * <li>{@link Ext.form.TextField}</li>
- * <li>{@link Ext.form.VTypes}</li>
- * <li>{@link Ext.form.BasicForm#doAction BasicForm.doAction <b>clientValidation</b> notes}</li>
- * <li><tt>{@link Ext.form.FormPanel#monitorValid monitorValid}</tt></li>
- * </ul></div>
- *
- * <p><b><u>Form Submission</u></b></p>
- * <p>By default, Ext Forms are submitted through Ajax, using {@link Ext.form.Action}. To enable normal browser
- * submission of the {@link Ext.form.BasicForm BasicForm} contained in this FormPanel, see the
- * <tt><b>{@link Ext.form.BasicForm#standardSubmit standardSubmit}</b></tt> option.</p>
- *
- * @constructor
- * @param {Object} config Configuration options
- * @xtype form
