- The label text to display next to this Component (defaults to '')
This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager.
Example use:
new Ext.FormPanel({
+Adds a menu item that contains a checkbox by default, but can also be part of a radio group.
Config Options
|
| activeClass : String The CSS class to use when the item becomes activated (defaults to "x-menu-item-active") | BaseItem |
| allowDomMove : Boolean Whether the component can move the Dom node when rendering (defaults to true). | Component |
| altText : String The altText to use for the icon, if it exists. Defaults to ''. | Item |
| applyTo : MixedSpecify the id of the element, a DOM element or an existing Element corresponding to a DIV
+that is already present in... Specify the id of the element, a DOM element or an existing Element corresponding to a DIV
+that is already present in the document that specifies some structural markup for this
+component.
+- Description :
+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.
+
+- Notes :
+When 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 |
| autoEl : MixedA tag name or DomHelper spec used to create the Element which will

+You do not normally ne... A tag name or DomHelper spec used to create the Element which will
+encapsulate this Component.
+ You do not normally need to specify this. For the base classes Ext.Component, Ext.BoxComponent,
+and Ext.Container, this defaults to 'div'. The more complex Ext classes use a more complex
+DOM structure created by their own onRender methods.
+ This is intended to allow the developer to create application-specific utility Components encapsulated by
+different DOM elements. Example usage: {
+ xtype: 'box',
+ autoEl: {
+ tag: 'img',
+ src: 'http://www.example.com/example.jpg'
+ }
+}, {
+ xtype: 'box',
+ autoEl: {
+ tag: 'blockquote',
+ html: 'autoEl is cool!'
+ }
+}, {
+ xtype: 'container',
+ autoEl: 'ul',
+ cls: 'ux-unordered-list',
+ items: {
+ xtype: 'box',
+ autoEl: 'li',
+ html: 'First list item'
+ }
+}

+for this component.
+
+- Description :
+
This config option is used to take an existing HTML element and place it in the layout element
+of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.
+- Notes :
+
The specified HTML element is appended to the layout element of the component after any configured
+HTML has been inserted, and so the document will not contain this element at the time the render event is fired.
+The specified HTML element used will not participate in any layout
+scheme that the Component may use. It is just HTML. Layouts operate on child items .
+Add either the x-hidden or the x-hide-display CSS class to
+prevent a brief flicker of the content before it is rendered to the panel.

- How this component should be hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset position) and "display" (css display) - defaults to "display". For Containers which may be hidden and shown as part of a card layout Container such as a TabPanel, it is recommended that hideMode is configured as "offsets". This ensures that hidden Components still have height and width so that layout managers can perform measurements when calculating layouts.

-
- A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. The component must have either a stateId or id assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a component. 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

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.

+ DOM events from ExtJs Components
+ While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this
+is usually only done when extra value can be added. For example the DataView's
+click event passing the node clicked on. To access DOM
+events directly from a Component's HTMLElement, listeners must be added to the Element after the Component
+has been rendered. A plugin can simplify this step: // Plugin is configured with a listeners config object.
+// The Component is appended to the argument list of all handler functions.
+Ext.DomObserver = Ext.extend(Object, {
+ constructor: function(config) {
+ this.listeners = config.listeners ? config.listeners : config;
+ },
+
+ // Component passes itself into plugin's init method
+ init: function(c) {
+ var p, l = this.listeners;
+ for (p in l) {
+ if (Ext.isFunction(l[p])) {
+ l[p] = this.createHandler(l[p], c);
+ } else {
+ l[p].fn = this.createHandler(l[p].fn, c);
+ }
+ }
+
+ // Add the listeners to the Element immediately following the render call
+ c.render = c.render.createSequence(function() {
+ var e = c.getEl();
+ if (e) {
+ e.on(l);
+ }
+ });
+ },
+
+ createHandler: function(fn, c) {
+ return function(e) {
+ fn.call(this, e, c);

+ }

+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

+specifying into which ancestor Container to place a named reference to this Component.
+ The ancestor axis can be traversed by using '/' characters in the path.
+For example, to put a reference to a Toolbar Button into the Panel which owns the Toolbar: var myGrid = new Ext.grid.EditorGridPanel({
+ title: 'My EditorGridPanel',
+ store: myStore,
+ colModel: myColModel,
+ tbar: [{

+ ref: '../saveButton'
+ }],
+ listeners: {
+ afteredit: function() {
+// The button reference is in the GridPanel
+ myGrid.saveButton.enable();
+ }
+ }
+});
+ In the code above, if the ref had been 'saveButton'
+the reference would have been placed into the Toolbar. Each '/' in the ref
+moves up one level from the Component's ownerCt .

| stateful : BooleanA flag which causes the Component to attempt to restore the state of

+internal properties from a saved state on startup. The component must have
+either a stateId or id assigned
+for state to be managed. Auto-generated ids are not guaranteed to be stable
+across page loads and cannot be relied upon to save and restore the same
+state for a component.
+ 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({
+ expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
+}));
+ A stateful Component attempts to save state when one of the events
+listed in the stateEvents configuration fires.
+ To save state, a stateful Component first serializes its state by
+calling getState . By default, this function does
+nothing. The developer must provide an implementation which returns an
+object hash which represents the Component's restorable state.
+ The value yielded by getState is passed to Ext.state.Manager.set
+which uses the configured Ext.state.Provider to save the object
+keyed by the Component's stateId , or, if that is not
+specified, its id .
+ During construction, a stateful Component attempts to restore
+its state by calling Ext.state.Manager.get passing the
+stateId , or, if that is not specified, the
+id .
+ The resulting object is passed to applyState .
+The default implementation of applyState simply copies
+properties into the object, but a developer may override this to support
+more behaviour.
+ You can perform extra processing on state save and restore by attaching
+handlers to the beforestaterestore, staterestore,
+beforestatesave and statesave events. | Component |
