-/**
- * @class Ext.form.FormPanel
- * @extends Ext.Panel
- *
Standard form container.
- *
- * Layout
- * By default, FormPanel is configured with layout:'form' 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.
- *
- * BasicForm
- * Although not listed as configuration options of FormPanel, the FormPanel class accepts all
- * of the config options required to configure its internal {@link Ext.form.BasicForm} for:
- *
- * - {@link Ext.form.BasicForm#fileUpload file uploads}
- * - functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form
- *
- *
- * Note: If subclassing FormPanel, any configuration options for the BasicForm must be applied to
- * the initialConfig property of the FormPanel. Applying {@link Ext.form.BasicForm BasicForm}
- * configuration settings to this will not affect the BasicForm's configuration.
- *
- * Form Validation
- * For information on form validation see the following:
- *
- * - {@link Ext.form.TextField}
- * - {@link Ext.form.VTypes}
- * - {@link Ext.form.BasicForm#doAction BasicForm.doAction clientValidation notes}
- * - {@link Ext.form.FormPanel#monitorValid monitorValid}
- *
- *
- * Form Submission
- * 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
- * {@link Ext.form.BasicForm#standardSubmit standardSubmit} option.
- *
- * @constructor
- * @param {Object} config Configuration options
- * @xtype form
