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 {@link Ext.state.Manager#set} * which uses the configured {@link Ext.state.Provider} to save the object * keyed by the Component's <code>{@link stateId}</code>, or, if that is not * specified, its <code>{@link #id}</code>. * During construction, a stateful Component attempts to restore * its state by calling {@link Ext.state.Manager#get} passing the * <code>{@link #stateId}</code>, or, if that is not specified, the * <code>{@link #id}</code>. * The resulting object is passed to <code>applyState</code>. * The default implementation of <code>applyState</code> 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 {@link #beforestaterestore}, {@link #staterestore}, * {@link #beforestatesave} and {@link #statesave} events. */ /** * @cfg {String} stateId * The unique id for this component to use for state management purposes * (defaults to the component id if one was set, otherwise null if the * component is using a generated id). * See <code>{@link #stateful}</code> for an explanation of saving and * restoring Component state. */ /** * @cfg {Array} stateEvents * An array of events that, when fired, should trigger this component to * save its state (defaults to none). <code>stateEvents</code> may be any type * of event supported by this component, including browser or custom events * (e.g., <tt>['click', 'customerchange']</tt>). * See <code>{@link #stateful}</code> for an explanation of saving and * restoring Component state. */ /** * @cfg {Mixed} autoEl * A tag name or {@link Ext.DomHelper DomHelper} spec used to create the {@link #getEl Element} which will * encapsulate this Component. * You do not normally need to specify this.

/** * @class Ext.Container * @extends Ext.BoxComponent * Base class for any {@link Ext.BoxComponent} that may contain other Components. Containers handle the * basic behavior of containing items, namely adding, inserting and removing items. * * The most commonly used Container classes are {@link Ext.Panel}, {@link Ext.Window} and {@link Ext.TabPanel}. * If you do not need the capabilities offered by the aforementioned classes you can create a lightweight * Container to be encapsulated by an HTML element to your specifications by using the * <tt>{@link Ext.Component#autoEl autoEl}</tt> config option. This is a useful technique when creating * embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels} * for example. * * The code below illustrates both how to explicitly create a Container, and how to implicitly * create one using the <tt>'container'</tt> xtype:<pre><code> // explicitly create a Container var embeddedColumns = new Ext.Container({ autoEl: 'div', // This is the default layout: 'column', defaults: { // implicitly create Container by specifying xtype xtype: 'container', autoEl: 'div', // This is the default. layout: 'form', columnWidth: 0.5, style: { padding: '10px' } }, // The two items below will be Ext.Containers, each encapsulated by a <DIV> element. items: [{ items: { xtype: 'datefield', name: 'startDate', fieldLabel: 'Start date' } }, { items: { xtype: 'datefield', name: 'endDate', fieldLabel: 'End date' } }] });</code></pre> * * Layout * Container classes delegate the rendering of child Components to a layout * manager class which must be configured into the Container using the * <code>{@link #layout}</code> configuration property. * When either specifying child <code>{@link #items}</code> of a Container, * or dynamically {@link #add adding} Components to a Container, remember to * consider how you wish the Container to arrange those child elements, and * whether those child elements need to be sized using one of Ext's built-in * <code>{@link #layout}</code> schemes. By default, Containers use the * {@link Ext.layout.ContainerLayout ContainerLayout} scheme which only * renders child components, appending them one after the other inside the * Container, and does not apply any sizing at all. * A common mistake is when a developer neglects to specify a * <code>{@link #layout}</code> (e.g. widgets like GridPanels or * TreePanels are added to Containers for which no <tt>{@link #layout}</tt> * has been specified). If a Container is left to use the default * {@link Ext.layout.ContainerLayout ContainerLayout} scheme, none of its * child components will be resized, or changed in any way when the Container * is resized. * Certain layout managers allow dynamic addition of child components. * Those that do include {@link Ext.layout.CardLayout}, * {@link Ext.layout.AnchorLayout}, {@link Ext.layout.FormLayout}, and * {@link Ext.layout.TableLayout}. For example:<pre><code> // Create the GridPanel. var myNewGrid = new Ext.grid.GridPanel({ store: myStore, columns: myColumnModel, title: 'Results', // the title becomes the title of the tab }); myTabPanel.add(myNewGrid); // {@link Ext.TabPanel} implicitly uses {@link Ext.layout.CardLayout CardLayout} myTabPanel.{@link Ext.TabPanel#setActiveTab setActiveTab}(myNewGrid); * </code></pre> * The example above adds a newly created GridPanel to a TabPanel. Note that * a TabPanel uses {@link Ext.layout.CardLayout} as its layout manager which * means all its child items are sized to {@link Ext.layout.FitLayout fit} * exactly into its client area. * Overnesting is a common problem. * An example of overnesting occurs when a GridPanel is added to a TabPanel * by wrapping the GridPanel inside a wrapping Panel (that has no * <tt>{@link #layout}</tt> specified) and then add that wrapping Panel * to the TabPanel. The point to realize is that a GridPanel is a * Component which can be added directly to a Container. If the wrapping Panel * has no <tt>{@link #layout}</tt> configuration, then the overnested * GridPanel will not be sized as expected. </code></pre> * * Adding via remote configuration * * A server side script can be used to add Components which are generated dynamically on the server. * An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server * based on certain parameters: * <pre><code> // execute an Ajax request to invoke server side script: Ext.Ajax.request({ url: 'gen-invoice-grid.php', // send additional parameters to instruct server script params: { startDate: Ext.getCmp('start-date').getValue(), endDate: Ext.getCmp('end-date').getValue() }, // process the response object to add it to the TabPanel: success: function(xhr) { var newComponent = eval(xhr.responseText); // see discussion below myTabPanel.add(newComponent); // add the component to the TabPanel myTabPanel.setActiveTab(newComponent); }, failure: function() { Ext.Msg.alert("Grid create failed", "Server communication failure"); } }); </code></pre> * The server script needs to return an executable Javascript statement which, when processed * using <tt>eval()</tt>, will return either a config object with an {@link Ext.Component#xtype xtype}, * or an instantiated Component. The server might return this for example:<pre><code> (function() { function formatDate(value){ return value ? value.dateFormat('M d, Y') : ''; }; var store = new Ext.data.Store({ url: 'get-invoice-data.php', baseParams: { startDate: '01/01/2008', endDate: '01/31/2008' }, reader: new Ext.data.JsonReader({ record: 'transaction', idProperty: 'id', totalRecords: 'total' }, [ 'customer', 'invNo', {name: 'date', type: 'date', dateFormat: 'm/d/Y'}, {name: 'value', type: 'float'} ]) }); var grid = new Ext.grid.GridPanel({ title: 'Invoice Report', bbar: new Ext.PagingToolbar(store), store: store, columns: [ {header: "Customer", width: 250, dataIndex: 'customer', sortable: true}, {header: "Invoice Number", width: 120, dataIndex: 'invNo', sortable: true}, {header: "Invoice Date", width: 100, dataIndex: 'date', renderer: formatDate, sortable: true}, {header: "Value", width: 120, dataIndex: 'value', renderer: 'usMoney', sortable: true} ], }); store.load(); return grid; // return instantiated component })(); </code></pre> * When the above code fragment is passed through the <tt>eval</tt> function in the success handler * of the Ajax request, the code is executed by the Javascript processor, and the anonymous function * runs, and returns the instantiated grid component. * Note: since the code above is generated by a server script, the <tt>baseParams</tt> for * the Store, the metadata to allow generation of the Record layout, and the ColumnModel * can all be generated into the code since these are all known on the server. * * @xtype container */ Ext.Container = Ext.extend(Ext.BoxComponent, { /** * @cfg {Boolean} monitorResize * True to automatically monitor window resize events to handle anything that is sensitive to the current size * of the viewport.

* @class Ext.layout.CardLayout
* @extends Ext.layout.FitLayout
* This layout manages multiple child Components, each fitted to the Container, where only a single child Component can be
* visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc.
* This class is intended to be extended or created via the layout:'card' {@link Ext.Container#layout} config,
* and should generally not need to be created directly via the new keyword.
* The CardLayout's focal method is {@link #setActiveItem}. Since only one panel is displayed at a time,
* the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
* the next panel to display. The layout itself does not provide a user interface for handling this navigation,
* so that functionality must be provided by the developer.
* In the following example, a simplistic wizard setup is demonstrated. A button bar is added
* to the footer of the containing panel to provide navigation buttons. The buttons will be handled by a
* common navigation routine -- for this example, the implementation of that routine has been ommitted since
* it can be any type of custom logic. Note that other uses of a CardLayout (like a tab control) would require a
* completely different implementation. For serious implementations, a better approach would be to extend
* CardLayout to provide the custom functionality needed. Example usage:
* <pre><code>
var navHandler = function(direction){
// This routine could contain business logic required to manage the navigation steps.
// It would call setActiveItem as needed, manage navigation button state, handle any
// branching logic that might be required, handle alternate actions like cancellation
// or finalization, etc. A complete wizard implementation could get pretty
// sophisticated depending on the complexity required, and should probably be
// done as a subclass of CardLayout in a real-world implementation.
};

title: 'Example Wizard',
layout:'card',
activeItem: 0, // make sure the active item is set on the container config!
bodyStyle: 'padding:15px',
defaults: {
// applied to each contained panel
border:false
},
// just an example of one possible navigation scheme, using buttons

* @class Ext.layout.AnchorLayout
* @extends Ext.layout.ContainerLayout
* This is a layout that enables anchoring of contained elements relative to the container's dimensions.
* If the container is resized, all anchored items are automatically rerendered according to their
* <tt>{@link #anchor}</tt> rules.
* This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout}
* config, and should generally not need to be created directly via the new keyword.
* AnchorLayout does not have any direct config options (other than inherited ones). By default,
* AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
* container using the AnchorLayout can supply an anchoring-specific config property of anchorSize.
* If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
* anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
* logic if necessary. For example:
* <pre><code>
var viewport = new Ext.Viewport({
layout:'anchor',
anchorSize: {width:800, height:600},
items:[{
title:'Item 1',
html:'Content 1',
width:800,
anchor:'right 20%'
},{
title:'Item 2',
html:'Content 2',
width:300,
anchor:'50% 30%'
},{
title:'Item 3',
html:'Content 3',
width:600,
anchor:'-100 50%'
}]

* added to an AnchorLayout accept an anchoring-specific config property of anchor which is a string
* containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
* The following types of anchor values are supported:<div class="mdetail-params"><ul>
*
* <li>Percentage : Any value between 1 and 100, expressed as a percentage.<div class="sub-desc">
* The first anchor is the percentage width that the item should take up within the container, and the

// two values specified
