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.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 next panel to display * (or its id or index). The layout itself does not provide a user interface for handling this navigation, * so that functionality must be provided by the developer. * * To change the active card of a container, call the setActiveItem method of its layout: * * @example * var p = Ext.create('Ext.panel.Panel', { * layout: 'card', * items: [ * { html: 'Card 1' }, * { html: 'Card 2' } * ], * renderTo: Ext.getBody() * }); * * p.getLayout().setActiveItem(1); * * The {@link Ext.Component#beforedeactivate beforedeactivate} and {@link Ext.Component#beforeactivate beforeactivate} * events can be used to prevent a card from activating or deactivating by returning `false`. * * @example * var active = 0; * var main = Ext.create('Ext.panel.Panel', { * renderTo: Ext.getBody(), * width: 200, * height: 200, * layout: 'card', * tbar: [{ * text: 'Next', * handler: function(){ * var layout = main.getLayout(); * ++active; * layout.setActiveItem(active); * active = main.items.indexOf(layout.getActiveItem()); * } * }], * items: [{ * title: 'P1' * }, { * title: 'P2' * }, { * title: 'P3', * listeners: { * beforeactivate: function(){ * return false; * } * } * }] * }); * * 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. 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 * var navigate = function(panel, 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. * var layout = panel.getLayout(); * layout[direction](); * Ext.getCmp('move-prev').setDisabled(!layout.getPrev()); * Ext.getCmp('move-next').setDisabled(!layout.getNext()); * }; * * Ext.create('Ext.panel.Panel', { * title: 'Example Wizard', * width: 300, * height: 200, * layout: 'card', * bodyStyle: 'padding:15px', * defaults: { * // applied to each contained panel * border: false * }, * // just an example of one possible navigation scheme, using buttons * bbar: [ * { * id: 'move-prev', * text: 'Back', * handler: function(btn) { * navigate(btn.up("panel"), "prev"); * }, * disabled: true * }, * '->', // greedy spacer so that the buttons are aligned to each side * { * id: 'move-next', * text: 'Next', * handler: function(btn) { * navigate(btn.up("panel"), "next"); * } * } * ], * // the panels (or "cards") within the layout * items: [{ * id: 'card-0', * html: '<h1>Welcome to the Wizard!</h1><p>Step 1 of 3</p>' * },{ * id: 'card-1', * html: '<p>Step 2 of 3</p>' * },{ * id: 'card-2', * html: '<h1>Congratulations!</h1><p>Step 3 of 3 - Complete</p>' * }], * renderTo: Ext.getBody() * }); */ Ext.define('Ext.layout.container.Card', { /* Begin Definitions */ extend: 'Ext.layout.container.Fit', alternateClassName: 'Ext.layout.CardLayout', alias: 'layout.card', /* End Definitions */ type: 'card', hideInactive: true, /** * @cfg {Boolean} deferredRender * True to render each contained item at the time it becomes active, false to render all contained items * as soon as the layout is rendered (defaults to false).

/** * @author Ed Spencer * @aside guide proxies * * AjaxProxy is one of the most widely-used ways of getting data into your application. It uses AJAX * requests to load data from the server, usually to be placed into a {@link Ext.data.Store Store}. * Let's take a look at a typical setup. Here we're going to set up a Store that has an AjaxProxy. * To prepare, we'll also set up a {@link Ext.data.Model Model}: * * Ext.define('User', { * extend: 'Ext.data.Model', * config: { * fields: ['id', 'name', 'email'] * } * }); * * // The Store contains the AjaxProxy as an inline configuration * var store = Ext.create('Ext.data.Store', { * model: 'User', * proxy: { * type: 'ajax', * url : 'users.json' * } * }); * * store.load(); * * Our example is going to load user data into a Store, so we start off by defining a * {@link Ext.data.Model Model} with the fields that we expect the server to return. Next we set up * the Store itself, along with a {@link Ext.data.Store#proxy proxy} configuration. This * configuration was automatically turned into an Ext.data.proxy.Ajax instance, with the url we * specified being passed into AjaxProxy's constructor. It's as if we'd done this: * * Ext.create('Ext.data.proxy.Ajax', { * config: { * url: 'users.json', * model: 'User', * reader: 'json' * } * }); * * A couple of extra configurations appeared here - {@link #model} and {@link #reader}. These are * set by default when we create the proxy via the Store - the Store already knows about the Model, * and Proxy's default {@link Ext.data.reader.Reader Reader} is {@link Ext.data.reader.Json JsonReader}. * * Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we * configured ('users.json' in this case). As we're performing a read, it sends a GET request to * that url (see {@link #actionMethods} to customize this - by default any kind of read will be sent * as a GET request and any kind of write will be sent as a POST request). * * ## Limitations * * AjaxProxy cannot be used to retrieve data from other domains. If your application is running on * http://domainA.com it cannot load data from http://domainB.com because browsers have a built-in * security policy that prohibits domains talking to each other via AJAX. * * If you need to read data from another domain and can't set up a proxy server (some software that * runs on your own domain's web server and transparently forwards requests to http://domainB.com, * making it look like they actually came from http://domainA.com), you can use * {@link Ext.data.proxy.JsonP} and a technique known as JSON-P (JSON with Padding), which can help * you get around the problem so long as the server on http://domainB.com is set up to support * JSON-P responses. See {@link Ext.data.proxy.JsonP JsonPProxy}'s introduction docs for more details. * * ## Readers and Writers * * AjaxProxy can be configured to use any type of {@link Ext.data.reader.Reader Reader} to decode * the server's response. If no Reader is supplied, AjaxProxy will default to using a * {@link Ext.data.reader.Json JsonReader}. Reader configuration can be passed in as a simple * object, which the Proxy automatically turns into a {@link Ext.data.reader.Reader Reader} instance: * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * config: { * model: 'User', * reader: { * type: 'xml', * root: 'users' * } * } * }); * * proxy.getReader(); //returns an {@link Ext.data.reader.Xml XmlReader} instance based on the config we supplied * * ## Url generation * * AjaxProxy automatically inserts any sorting, filtering, paging and grouping options into the url * it generates for each request. These are controlled with the following configuration options: * * - {@link #pageParam} - controls how the page number is sent to the server (see also * {@link #startParam} and {@link #limitParam}) * - {@link #sortParam} - controls how sort information is sent to the server * - {@link #groupParam} - controls how grouping information is sent to the server * - {@link #filterParam} - controls how filter information is sent to the server * * Each request sent by AjaxProxy is described by an {@link Ext.data.Operation Operation}. To see * how we can customize the generated urls, let's say we're loading the Proxy with the following * Operation: * * var operation = Ext.create('Ext.data.Operation', { * action: 'read', * page : 2 * }); * * Now we'll issue the request for this Operation by calling {@link #read}: * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users' * }); * * proxy.read(operation); // GET /users?page=2 * * Easy enough - the Proxy just copied the page property from the Operation. We can customize how * this page data is sent to the server: * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users', * pageParam: 'pageNumber' * }); * * proxy.read(operation); // GET /users?pageNumber=2 * * Alternatively, our Operation could have been configured to send start and limit parameters * instead of page: * * var operation = Ext.create('Ext.data.Operation', { * action: 'read', * start : 50, * limit : 25 * }); * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users' * }); * * proxy.read(operation); // GET /users?start=50&limit;=25 * * Again we can customize this url: * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users', * startParam: 'startIndex', * limitParam: 'limitIndex' * }); * * proxy.read(operation); // GET /users?startIndex=50&limitIndex;=25 * * AjaxProxy will also send sort and filter information to the server. Let's take a look at how this * looks with a more expressive Operation object: * * var operation = Ext.create('Ext.data.Operation', { * action: 'read', * sorters: [ * Ext.create('Ext.util.Sorter', { * property : 'name', * direction: 'ASC' * }), * Ext.create('Ext.util.Sorter', { * property : 'age', * direction: 'DESC' * }) * ], * filters: [ * Ext.create('Ext.util.Filter', { * property: 'eyeColor', * value : 'brown' * }) * ] * }); * * This is the type of object that is generated internally when loading a {@link Ext.data.Store Store} * with sorters and filters defined. By default the AjaxProxy will JSON encode the sorters and * filters, resulting in something like this (note that the url is escaped before sending the * request, but is left unescaped here for clarity): * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users' * }); * * proxy.read(operation); // GET /users?sort=[{"property":"name","direction":"ASC"},{"property":"age","direction":"DESC"}]&filter;=[{"property":"eyeColor","value":"brown"}] * * We can again customize how this is created by supplying a few configuration options. Let's say * our server is set up to receive sorting information is a format like "sortBy=name#ASC,age#DESC". * We can configure AjaxProxy to provide that format like this: * * var proxy = Ext.create('Ext.data.proxy.Ajax', { * url: '/users', * sortParam: 'sortBy', * filterParam: 'filterBy', * * // our custom implementation of sorter encoding - turns our sorters into "name#ASC,age#DESC" * encodeSorters: function(sorters) { * var length = sorters.length, * sortStrs = [], * sorter, i; * * for (i = 0; i < length; i++) { * sorter = sorters[i]; * * sortStrs[i] = sorter.property + '#' + sorter.direction; * } * * return sortStrs.join(","); * } * }); * * proxy.read(operation); // GET /users?sortBy=name#ASC,age#DESC&filterBy;=[{"property":"eyeColor","value":"brown"}] * * We can also provide a custom {@link #encodeFilters} function to encode our filters. * * @constructor * Note that if this HttpProxy is being used by a {@link Ext.data.Store Store}, then the Store's * call to {@link Ext.data.Store#method-load load} will override any specified callback and params * options. In this case, use the {@link Ext.data.Store Store}'s events to modify parameters, or * react to loading events. * * @param {Object} config (optional) Config object. * If an options parameter is passed, the singleton {@link Ext.Ajax} object will be used to * make the request. */ Ext.define('Ext.data.proxy.Ajax', { extend: 'Ext.data.proxy.Server', requires: ['Ext.util.MixedCollection', 'Ext.Ajax'], alias: 'proxy.ajax', alternateClassName: ['Ext.data.HttpProxy', 'Ext.data.AjaxProxy'], config: { /** * @cfg {Boolean} withCredentials * This configuration is sometimes necessary when using cross-origin resource sharing. * @accessor */ withCredentials: false, /** * @cfg {String} username * Most oData feeds require basic HTTP authentication.
