- * Improved John Resig's inheritance, based on:
- *
- * Simple JavaScript Inheritance
- * By John Resig http://ejohn.org/
- * MIT Licensed.
- *
- * Adds "include()"
- *
- * Defines The Class object. That object can be used to define and inherit classes using
- * the extend() method.
- *
- * Example:
- *
- * var Person = instance.web.Class.extend({
- *  init: function(isDancing){
- *     this.dancing = isDancing;
- *   },
- *   dance: function(){
- *     return this.dancing;
- *   }
- * });
- *
- * The init() method act as a constructor. This class can be instancied this way:
- *
- * var person = new Person(true);
- * person.dance();
- *
- * The Person class can also be extended again:
- *
- * var Ninja = Person.extend({
- *   init: function(){
- *     this._super( false );
- *   },
- *   dance: function(){
- *     // Call the inherited version of dance()
- *     return this._super();
- *   },
- *   swingSword: function(){
- *     return true;
- *   }
- * });
- *
- * When extending a class, each re-defined method can use this._super() to call the previous
- * implementation of that method.

 /**
- * Base class for all visual components. Provides a lot of functionalities helpful
- * for the management of a part of the DOM.
- *
- * Widget handles:
- * - Rendering with QWeb.
- * - Life-cycle management and parenting (when a parent is destroyed, all its children are
- *     destroyed too).
- * - Insertion in DOM.
- *
- * Guide to create implementations of the Widget class:
- * ==============================================
- *
- * Here is a sample child class:
- *
- * MyWidget = instance.base.Widget.extend({
- *     // the name of the QWeb template to use for rendering
- *     template: "MyQWebTemplate",
- *
- *     init: function(parent) {
- *         this._super(parent);
- *         // stuff that you want to init before the rendering
- *     },
- *     start: function() {
- *         // stuff you want to make after the rendering, `this.$el` holds a correct value
- *         this.$el.find(".my_button").click(/* an example of event binding * /);
- *
- *         // if you have some asynchronous operations, it's a good idea to return
- *         // a promise in start()
- *         var promise = this.rpc(...);
- *         return promise;
- *     }
- * });
- *
- * Now this class can simply be used with the following syntax:
- *
- * var my_widget = new MyWidget(this);
- * my_widget.appendTo($(".some-div"));
- *
- * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
- * DOM inside the ".some-div" div and its events were binded.
- *
- * And of course, when you don't need that widget anymore, just do:
- *
- * my_widget.destroy();
- *
- * That will kill the widget in a clean way and erase its content from the dom.

+ * Simple JavaScript Inheritance
+ * By John Resig http://ejohn.org/
+ * MIT Licensed.
+ *
+ * Adds "include()"
+ *
+ * Defines The Class object. That object can be used to define and inherit classes using
+ * the extend() method.
+ *
+ * Example:
+ *
+ * var Person = openerp.web.Class.extend({

+ *     this.dancing = isDancing;
+ *   },
+ *   dance: function(){
+ *     return this.dancing;
+ *   }
+ * });
+ *
+ * The init() method act as a constructor. This class can be instancied this way:
+ *
+ * var person = new Person(true);
+ * person.dance();
+ *
+ * The Person class can also be extended again:
+ *
+ * var Ninja = Person.extend({
+ *   init: function(){
+ *     this._super( false );
+ *   },
+ *   dance: function(){
+ *     // Call the inherited version of dance()
+ *     return this._super();
+ *   },
+ *   swingSword: function(){
+ *     return true;
+ *   }
+ * });
+ *
+ * When extending a class, each re-defined method can use this._super() to call the previous
+ * implementation of that method.

+/**
+ * Base class for all visual components. Provides a lot of functionalities helpful
+ * for the management of a part of the DOM.
+ *
+ * Widget handles:
+ * - Rendering with QWeb.
+ * - Life-cycle management and parenting (when a parent is destroyed, all its children are
+ *     destroyed too).
+ * - Insertion in DOM.
+ *
+ * Guide to create implementations of the Widget class:
+ * ==============================================
+ *
+ * Here is a sample child class:
+ *
+ * MyWidget = openerp.base.Widget.extend({
+ *     // the name of the QWeb template to use for rendering
+ *     template: "MyQWebTemplate",
+ *
+ *     init: function(parent) {
+ *         this._super(parent);
+ *         // stuff that you want to init before the rendering
+ *     },
+ *     start: function() {
+ *         // stuff you want to make after the rendering, `this.$el` holds a correct value
+ *         this.$el.find(".my_button").click(/* an example of event binding * /);
+ *
+ *         // if you have some asynchronous operations, it's a good idea to return
+ *         // a promise in start()
+ *         var promise = this.rpc(...);
+ *         return promise;
+ *     }
+ * });
+ *
+ * Now this class can simply be used with the following syntax:
+ *
+ * var my_widget = new MyWidget(this);
+ * my_widget.appendTo($(".some-div"));
+ *
+ * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
+ * DOM inside the ".some-div" div and its events were binded.
+ *
+ * And of course, when you don't need that widget anymore, just do:
+ *
+ * my_widget.destroy();
+ *
+ * That will kill the widget in a clean way and erase its content from the dom.
+ */
