/** * Represents an Ext JS application, which is typically a single page app using a * {@link Ext.container.Viewport Viewport}. * * An application consists of one or more Views. The behavior of a View is managed by its * corresponding {@link Ext.app.ViewController ViewController} and {@link Ext.app.ViewModel * ViewModel}. * * Global activities are coordinated by {@link Ext.app.Controller Controllers} which are * ultimately instantiated by an instance of this (or a derived) class. * * Ext.application({ * name: 'MyApp', * * // An instance of this view is created and set as the Viewport: * autoCreateViewport: 'MyApp.view.Main' * }); * * This does several things. First it creates a global variable called 'MyApp' - all of * your Application's classes (such as its Models, Views and Controllers) will reside under * this single namespace, which drastically lowers the chances of colliding global variables. * * The MyApp global will also have a getApplication method to get a reference to the current * application: * * var app = MyApp.getApplication(); * * # Telling Application about the rest of the app * * Because an Ext.app.Application represents an entire app, we should tell it about the other * parts of the app - namely the Models, Views and Controllers that are bundled with the application. Let's say we have a blog management app; we * might have Models and Controllers for Posts and Comments, and Views for listing, adding and editing Posts and Comments. * Here's how we'd tell our Application about all these things: * * Ext.application({ * name: 'Blog', * * models: ['Post', 'Comment'], * * controllers: ['Posts', 'Comments'], * * launch: function() { * ... * } * }); * * Note that we didn't actually list the Views directly in the Application itself. This is because Views are managed by * Controllers, so it makes sense to keep those dependencies there. The Application will load each of the specified * Controllers using the pathing conventions laid out in the [application architecture guide](../application_architecture/application_architecture.html) - in this case * expecting the controllers to reside in app/controller/Posts.js and app/controller/Comments.js. In turn, each * Controller simply needs to list the Views it uses and they will be automatically loaded. Here's how our Posts * controller like be defined: * * Ext.define('MyApp.controller.Posts', { * extend: 'Ext.app.Controller', * views: ['posts.List', 'posts.Edit'], * * //the rest of the Controller here * }); * * Because we told our Application about our Models and Controllers, and our Controllers about their Views, Ext JS will * automatically load all of our app files for us. This means we don't have to manually add script tags into our html * files whenever we add a new class, but more importantly it enables us to create a minimized build of our entire * application using Sencha Cmd. * * # Deriving from Ext.app.Application * * Typically, applications do not derive directly from Ext.app.Application. Rather, the * configuration passed to `Ext.application` mimics what you might do in a derived class. * In some cases, however, it can be desirable to share logic by using a derived class * from `Ext.app.Application`. * * Derivation works as you would expect, but using the derived class should still be the * job of the `Ext.application` method. * * Ext.define('MyApp.Application', { * extend: 'Ext.app.Application', * name: 'MyApp', * ... * }); * * Ext.application('MyApp.Application'); * * For more information about writing Ext JS applications, please see the [application architecture guide](../../../application_architecture/application_architecture.html). * * [mvc]: #/guide/application_architecture */Ext.define('Ext.app.Application', { extend: 'Ext.app.Controller', requires: [ 'Ext.util.History', 'Ext.util.MixedCollection' ], isApplication: true, /** * @cfg {String} extend A class name to use with the `Ext.application` call.
