// @tag core/** * @class Ext * * The Ext namespace (global object) encapsulates all classes, singletons, and * utility methods provided by Sencha's libraries. * * Most user interface Components are at a lower level of nesting in the namespace, * but many common utility functions are provided as direct properties of the Ext namespace. * * Also many frequently used methods from other classes are provided as shortcuts * within the Ext namespace. For example {@link Ext#getCmp Ext.getCmp} aliases * {@link Ext.ComponentManager#get Ext.ComponentManager.get}. * * Many applications are initiated with {@link Ext#application Ext.application} which is * called once the DOM is ready. This ensures all scripts have been loaded, preventing * dependency issues. For example: * * Ext.application({ * name: 'MyApp', * * launch: function () { * Ext.Msg.alert(this.getName(), 'Ready to go!'); * } * }); * * <b><a href="http://www.sencha.com/products/sencha-cmd/">Sencha Cmd</a></b> is a free tool * for helping you generate and build Ext JS (and Sencha Touch) applications.
