929 * Base class for all visual components. Provides a lot of functionalities helpful
930 * for the management of a part of the DOM.
933 * - Rendering with QWeb.
934 * - Life-cycle management and parenting (when a parent is destroyed, all its children are
936 * - Insertion in DOM.
938 * Guide to create implementations of the Widget class:
939 * ==============================================
941 * Here is a sample child class:
943 * MyWidget = openerp.base.Widget.extend({
944 * // the name of the QWeb template to use for rendering
945 * template: "MyQWebTemplate",
947 * init: function(parent) {
948 * this._super(parent);
949 * // stuff that you want to init before the rendering
951 * start: function() {
952 * // stuff you want to make after the rendering, `this.$element` holds a correct value
953 * this.$element.find(".my_button").click(/* an example of event binding * /);
955 * // if you have some asynchronous operations, it's a good idea to return
956 * // a promise in start()
957 * var promise = this.rpc(...);
962 * Now this class can simply be used with the following syntax:
964 * var my_widget = new MyWidget(this);
965 * my_widget.appendTo($(".some-div"));
967 * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
968 * DOM inside the ".some-div" div and its events were binded.
970 * And of course, when you don't need that widget anymore, just do:
974 * That will kill the widget in a clean way and erase its content from the dom.
976 openerp.web.Widget = openerp.web.CallbackEnabled.extend(/** @lends openerp.web.Widget# */{
977 __parented_mixin: true,
979 * The name of the QWeb template that will be used for rendering. Must be
980 * redefined in subclasses or the default render() method can not be used.
986 * Tag name when creating a default $element.
991 * Constructs the widget and sets its parent if a parent is given.
993 * @constructs openerp.web.Widget
994 * @extends openerp.web.CallbackEnabled
996 * @param {openerp.web.Widget} parent Binds the current instance to the given Widget instance.
997 * When that widget is destroyed by calling stop(), the current instance will be
998 * destroyed too. Can be null.
999 * @param {String} element_id Deprecated. Sets the element_id. Only useful when you want
1000 * to bind the current Widget to an already existing part of the DOM, which is not compatible
1001 * with the DOM insertion methods provided by the current implementation of Widget. So
1002 * for new components this argument should not be provided any more.
