# 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

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();
            }
        });

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.

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.

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 amount of sub components that frequent calls to layout are expensive.

Container

| buttonAlign : String Valid values are "left," "center" and "right" (defaults to "center") | FormPanel

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'}.

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
- bbar (bottom bar)
- footer

Defaults to 'body'.

Panel

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
| 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

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 panel header icon (defaults to ''). | Panel
| id : String The unique id of this component (defaults to an auto-assigned id). | Component

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.

The title text to display in the panel header (defaults to ''). When a title is specified the header element will automatically be created and displayed unless header is explicitly set to false. If you don't want to specify a title at config time, but you may want one later, you must either specify a non-empty title (a blank space ' ' will do) or header:true so that the container element will get created.

An array of tool button configs to be added to the header tool area. Each tool config may contain the following properties:

- id : String

  Required. The type of tool to create. Values may be

  - `toggle` (Created by default when collapsible is `true`)
  - `close`
  - `minimize`
  - `maximize`
  - `restore`
  - `gear`
  - `pin`
  - `unpin`
  - `right`
  - `left`
  - `up`
  - `down`
  - `refresh`
  - `minus`
  - `plus`
  - `help`
  - `search`
  - `save`

- handler : Function

  Required. The function to call when clicked. Arguments passed are:

  - event : Ext.EventObject

    The click event.

  - toolEl : Ext.Element

    The tool Element.

  - Panel : Ext.Panel

    The host Panel

- scope : Object

  The scope in which to call the handler.

- qtip : String/Object

  A tip string, or a config argument to Ext.QuickTip.register

- hidden : Boolean

  True to initially render hidden.

- on : Object

  A listener config object specifiying event listeners in the format of an argument to addListener

Example usage:

    tools:[{
        id:'refresh',
        // hidden:true,
        handler: function(event, toolEl, panel){
            // refresh logic
        }
    }]

Note that apart from the toggle tool which is provided when a panel is collapsible, these tools only provide the visual button. Any required functionality must be provided by adding handlers that implement the necessary behavior.

Panel

| width : Number The width of this component in pixels (defaults to auto). | BoxComponent

The registered xtype to create. 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.

Adds a Component to this Container. Fires the beforeadd event before adding, then fires the add event after the component has been added.
Parameters:

- `component` : Ext.Component/Object
  The component to add.
  Ext uses lazy rendering, and will only render the added Component should it become necessary.
  A Component config object may be passed 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.

Returns:

- `Ext.Component`
  component The Component (or config object) that was added with the Container's default config values applied.

Container

Adds a button to this panel. Note that this method must be called prior to rendering. The preferred approach is to add buttons via the buttons config.
Parameters:

- `config` : String/Object
  A valid Ext.Button config. A string will become the text for a default button config, an object will be treated as a button config object.
- `handler` : Function
  The function to be called on button Ext.Button.click
- `scope` : Object
  The scope to use for the button handler function

Returns:

- `Ext.Button`
  The button that was added

Panel

addClass( `string cls` ) : void
Adds a CSS class to the component's underlying element.
Adds a CSS class to the component's underlying element.
Parameters:

- `cls` : string
  The CSS class name to add

Returns:

- `void`

Component

addEvents( `Object object` ) : void
Used to define events on this Observable
Used to define events on this Observable
Parameters:

- `object` : Object
  The object with the events defined

Returns:

- `void`

Observable

addListener( `String eventName`, `Function handler`, [`Object scope`], [`Object options`] ) : void
Appends an event handler to this component
Appends an event handler to this component
Parameters:

- `eventName` : String
  The type of event to listen for
- `handler` : Function
  The method the event invokes
- `scope` : Object
  (optional) The scope in which to execute the handler function. The handler function's "this" context.
- `options` : Object
  (optional) An object containing handler configuration properties. This may contain any of the following properties:
  - scope : Object

    The scope in which to execute the handler function. The handler function's "this" context.

  - delay : Number

    The number of milliseconds to delay the invocation of the handler after the event fires.

  - single : Boolean

    True to add a handler to handle just the next firing of the event, and then remove itself.

  - buffer {Number} Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

  Combining Options
  Using the options argument, it is possible to combine different types of listeners:
  A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)

      el.on('click', this.onClick, this, {
          single: true,
          delay: 100,
          forumId: 4
      });

  Attaching multiple handlers in 1 call
  The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers.

      foo.on({
          'click' : {
              fn: this.onClick,
              scope: this,
              delay: 100
          },
          'mouseover' : {
              fn: this.onMouseOver,
              scope: this
          },
          'mouseout' : {
              fn: this.onMouseOut,
              scope: this
          }
      });

  Or a shorthand syntax:

      foo.on({
          'click' : this.onClick,
          'mouseover' : this.onMouseOver,
          'mouseout' : this.onMouseOut,
           scope: this
      });
