Class Ext.form.FormPanel

Package:	Ext.form
Defined In:	Form.js
Class:	FormPanel
Extends:	Panel

Standard form container.

Although they are not listed, this class also accepts all the config options required to configure its internal Ext.form.BasicForm

The BasicForm is configured using the initialConfig of the FormPanel - that is the configuration object passed to the constructor. This means that if you subclass FormPanel, and you wish to configure the BasicForm, you will need to insert any configuration options for the BasicForm into the initialConfig property. Applying BasicForm configuration settings to this will not affect the BasicForm's configuration.

FormPanel uses a Ext.layout.FormLayout internally, and that is required for fields and labels to work correctly within the FormPanel's layout. To nest additional layout styles within a FormPanel, you should nest additional Panels or other containers that can provide additional layout functionality. You should not override FormPanel's layout.

By default, Ext Forms are submitted through Ajax, using Ext.form.Action. To enable normal browser submission of the Ext Form contained in this FormPanel, override the Form's onSubmit, and submit methods:

var myForm = new Ext.form.FormPanel({
        onSubmit: Ext.emptyFn,
        submit: function() {
            this.getForm().getEl().dom.submit();
        }
    });

Config Options

Config Options		Defined By
	activeItem : String/Number A string component id or the numeric index of the component that should be initially activated within the container's... A string component id or the numeric index of the component that should be initially activated within the container's layout on render. For example, activeItem: 'item-1' or activeItem: 0 (index 0 = the first item in the container's collection). activeItem only applies to layout styles that can display items one at a time (like Ext.layout.Accordion, Ext.layout.CardLayout and Ext.layout.FitLayout). Related to Ext.layout.ContainerLayout.activeItem.	Container
	allowDomMove : Boolean Whether the component can move the Dom node when rendering (defaults to true).	Component
	animCollapse : Boolean True to animate the transition when the panel is collapsed, false to skip the animation (defaults to true if the Ext.... True to animate the transition when the panel is collapsed, false to skip the animation (defaults to true if the Ext.Fx class is available, otherwise false).	Panel
	applyTo : Mixed The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document ... The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document that specifies some structural markup for this component. When applyTo is used, constituent parts of the component can also be specified by id or CSS class name within the main element, and the component being created may attempt to create its subcomponents from that markup if applicable. Using this config, a call to render() is not required. If applyTo is specified, any value passed for renderTo will be ignored and the target element's parent node will automatically be used as the component's container.	Component
	autoDestroy : Boolean If true the container will automatically destroy any contained component that is removed from it, else destruction mu... If true the container will automatically destroy any contained component that is removed from it, else destruction must be handled manually (defaults to true).	Container
	autoHeight : Boolean True to use height:'auto', false to use fixed height. Note: although many components inherit this config option, not ... True to use height:'auto', false to use fixed height. Note: although many components inherit this config option, not all will function as expected with a height of 'auto'. (defaults to false).	BoxComponent

A valid url spec according to the Updater Ext.Updater.update method. If autoLoad is not null, the panel will attempt to load its contents immediately upon render. The URL will become the default URL for this panel's body element, so it may be refreshed at any time.	Panel
	autoScroll : Boolean True to use overflow:'auto' on the panel's body element and show scroll bars automatically when necessary, false to c... True to use overflow:'auto' on the panel's body element and show scroll bars automatically when necessary, false to clip any overflowing content (defaults to false).	Panel

Note: although many components inherit this config option, not all will function as expected with a width of 'auto'. (defaults to false).	BoxComponent
	baseCls : String The base CSS class to apply to this panel's element (defaults to 'x-panel').	Panel
	bbar : Object/Array The bottom toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button co... The bottom toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button configs to be added to the toolbar. Note that this is not available as a property after render. To access the bottom toolbar after render, use getBottomToolbar.	Panel

True to display an interior border on the body element of the panel, false to hide it (defaults to true). This only applies when border == true. If border == true and bodyBorder == false, the border will display as a 1px wide inset border, giving the entire body element an inset appearance.	Panel
	bodyStyle : String/Object/Function Custom CSS styles to be applied to the body element in the format expected by Ext.Element.applyStyles (defaults to nu... Custom CSS styles to be applied to the body element in the format expected by Ext.Element.applyStyles (defaults to null).	Panel

True to display the borders of the panel's body element, false to hide them (defaults to true). By default, the border is a 2px wide inset border, but this can be further altered by setting bodyBorder to false.	Panel
	bufferResize : Boolean/Number When set to true (100 milliseconds) or a number of milliseconds, the layout assigned for this container will buffer t... When set to true (100 milliseconds) or a number of milliseconds, the layout assigned for this container will buffer the frequency it calculates and does a re-layout of components. This is useful for heavy containers or containers with a large quantity of sub-components for which frequent layout calls would be expensive.	Container
	buttonAlign : String Valid values are "left," "center" and "right" (defaults to "center")	FormPanel
	buttons : Array An array of Ext.Buttons or Ext.Button configs used to add buttons to the footer of this panel.	Panel

True to make sure the collapse/expand toggle button always renders first (to the left of) any other tools in the panel's title bar, false to render it last (defaults to true).	Panel
	collapsed : Boolean True to render the panel collapsed, false to render it expanded (defaults to false).	Panel
	collapsedCls : String A CSS class to add to the panel's element after it has been collapsed (defaults to 'x-panel-collapsed').	Panel
	collapsible : Boolean True to make the panel collapsible and have the expand/collapse toggle button automatically rendered into the header ... True to make the panel collapsible and have the expand/collapse toggle button automatically rendered into the header tool button area, false to keep the panel statically sized with no button (defaults to false).	Panel

An optional extra CSS class that will be added to this component's container (defaults to ''). This can be useful for adding customized styles to the container or any of its children using standard CSS rules.	Component

The default xtype of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component. This usually defaults to 'panel', but for Ext.form.FormPanel and Ext.form.FieldSet, the defaultType is 'textfield'.	Container
	defaults : Object A config object that will be applied to all components added to this container either via the items config or via the... A config object that will be applied to all components added to this container either via the items config or via the add or insert methods. The defaults config can contain any number of name/value property pairs to be added to each item, and should be valid for the types of items being added to the container. For example, to automatically apply padding to the body of each of a set of contained Ext.Panel items, you could pass: defaults: {bodyStyle:'padding:15px'}.	Container
	disabled : Boolean Render this component disabled (default is false).	Component
	disabledClass : String CSS class added to the component when it is disabled (defaults to "x-item-disabled").	Component
	draggable : Boolean True to enable dragging of this Panel (defaults to false). For custom drag/drop implementations, an Ext.Panel.DD conf... True to enable dragging of this Panel (defaults to false). For custom drag/drop implementations, an Ext.Panel.DD config could also be passed in this config instead of true. Ext.Panel.DD is an internal, undocumented class which moves a proxy Element around in place of the Panel's element, but provides no other behaviour during dragging or on drop. It is a subclass of Ext.dd.DragSource, so behaviour may be added by implementing the interface methods of Ext.dd.DragDrop eg: new Ext.Panel({ title: 'Drag me', x: 100, y: 100, renderTo: Ext.getBody(), floating: true, frame: true, width: 400, height: 200, draggable: { // Config option of Ext.Panel.DD class. // It's a floating Panel, so do not show a placeholder proxy in the original position. insertProxy: false, // Called for each mousemove event while dragging the DD object. onDrag : function(e){ // Record the x,y position of the drag proxy so that we can // position the Panel at end of drag. var pel = this.proxy.getEl(); this.x = pel.getLeft(true); this.y = pel.getTop(true); // Keep the Shadow aligned if there is one. var s = this.panel.getEl().shadow; if (s) { s.realign(this.x, this.y, pel.getWidth(), pel.getHeight()); } }, // Called on the mouseup event. endDrag : function(e){ this.panel.setPosition(this.x, this.y); } } }).show();	Panel

A comma-delimited list of panel elements to initialize when the panel is rendered. Normally, this list will be generated automatically based on the items added to the panel at config time, but sometimes it might be useful to make sure a structural element is rendered even if not specified at config time (for example, you may want to add a button or toolbar dynamically after the panel has been rendered). Adding those elements to this list will allocate the required placeholders in the panel when it is rendered. Valid values are header tbar (top bar) body (required) bbar (bottom bar) footer Defaults to 'body'.	Panel
	floating : Boolean True to float the panel (absolute position it with automatic shimming and shadow), false to display it inline where i... True to float the panel (absolute position it with automatic shimming and shadow), false to display it inline where it is rendered (defaults to false). Note that by default, setting floating to true will cause the panel to display at negative offsets so that it is hidden -- because the panel is absolute positioned, the position must be set explicitly after render (e.g., myPanel.setPosition(100,100);). Also, when floating a panel you should always assign a fixed width, otherwise it will be auto width and will expand to fill to the right edge of the viewport.	Panel
	footer : Boolean True to create the footer element explicitly, false to skip creating it. By default, when footer is not specified, if... True to create the footer element explicitly, false to skip creating it. By default, when footer is not specified, if one or more buttons have been added to the panel the footer will be created automatically, otherwise it will not.	Panel
	formId : String (optional) The id of the FORM tag (defaults to an auto-generated id).	FormPanel
	frame : Boolean True to render the panel with custom rounded borders, false to render with plain 1px square borders (defaults to false).	Panel
	header : Boolean True to create the header element explicitly, false to skip creating it. By default, when header is not specified, if... True to create the header element explicitly, false to skip creating it. By default, when header is not specified, if a title is set the header will be created automatically, otherwise it will not. If a title is set but header is explicitly set to false, the header will not be rendered.	Panel
	headerAsText : Boolean True to display the panel title in the header, false to hide it (defaults to true).	Panel
	height : Number The height of this component in pixels (defaults to auto).	BoxComponent
	hidden : Boolean Render this component hidden (default is false).	Component
	hideBorders : Boolean True to hide the borders of each contained component, false to defer to the component's existing border settings (def... True to hide the borders of each contained component, false to defer to the component's existing border settings (defaults to false).	Container

	hideMode : String How this component should hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset posi... How this component should hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset position) and "display" (css display) - defaults to "display".	Component
	hideParent : Boolean True to hide and show the component's container when hide/show is called on the component, false to hide and show the... True to hide and show the component's container when hide/show is called on the component, false to hide and show the component itself (defaults to false). For example, this can be used as a shortcut for a hide button on a window by setting hide:true on the button when adding it to its parent container.	Component
	html : String/Object An HTML fragment, or a DomHelper specification to use as the panel's body content (defaults to '').	Panel
	iconCls : String A CSS class that will provide a background image to be used as the header icon (defaults to ''). An example custom ic... A CSS class that will provide a background image to be used as the header icon (defaults to ''). An example custom icon class would be something like: .my-icon { background: url(../images/my-icon.gif) 0 6px no-repeat !important;}	Panel

A single item, or an array of child Components to be added to this container. Each item can be any type of object based on Ext.Component. Component config objects may also be specified in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the added Component will not be rendered immediately. To take advantage of this "lazy instantiation", set the Ext.Component.xtype config property to the registered type of the Component wanted. For a list of all available xtypes, see Ext.Component. If a single item is being passed, it should be passed directly as an object reference (e.g., items: {...}). Multiple items should be passed as an array of objects (e.g., items: [{...}, {...}]).

An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.	Component

A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available. To set the state provider for the current page: `Ext.state.Manager.setProvider(new Ext.state.CookieProvider());` Components attempt to save state when one of the events listed in the stateEvents configuration fires. You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events	Component

This config option is not used when passing a config object into a constructor. This config option is used only when lazy instantiation is being used, and a child item of a Container is being specified not as a fully instantiated Component, but as a Component config object. The xtype will be looked up at render time up to determine what type of child Component to create. The predefined xtypes are listed here. If you subclass Components to create your own Components, you may register them using Ext.ComponentMgr.registerType in order to be able to take advantage of lazy instantiation and rendering.	Component
	y : Number The local y (top) coordinate for this component if contained within a positioning container.	BoxComponent

Adds a Component to this Container. Fires the beforeadd event before adding, then fires the add event after the component has been added. You will never call the render method of a child Component when using a Container. Child Components are rendered by this Container's layout manager when this Container is first rendered. Certain layout managers allow dynamic addition of child components. Those that do include Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, Ext.layout.TableLayout. If the Container is already rendered when add is called, you may need to call doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once. When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must specify a layout manager which creates and manages the type of layout you have in mind. Omitting the layout config means that a basic layout manager is used which does nothnig but render child components sequentially into the Container. No sizing or positioning will be performed in this situation. Parameters: `component` : Ext.Component/Object The Component to add. Ext uses lazy rendering, and will only render the added Component should it become necessary, that is: when the Container is layed out either on first render or in response to a doLayout call. A Component config object may be passed instead of an instantiated Component object. The type of Component created from a config object is determined by the xtype config property. If no xtype is configured, the Container's defaultType is used. For a list of all available xtypes, see Ext.Component.

If you are using a Container object to house this Component, then do not use the render method. A Container's child Components are rendered by that Container's layout manager when the Container is first rendered. Certain layout managers allow dynamic addition of child components. Those that do include Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, Ext.layout.TableLayout. If the Container is already rendered when a new child Component is added, you may need to call the Container's doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once. When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind. Omitting the Container's layout config means that a basic layout manager is used which does nothnig but render child components sequentially into the Container. No sizing or positioning will be performed in this situation. Parameters: `container` : Element/HTMLElement/String (optional) The element this Component should be rendered into.
