866 * Base class for all visual components. Provides a lot of functionalities helpful
867 * for the management of a part of the DOM.
870 * - Rendering with QWeb.
871 * - Life-cycle management and parenting (when a parent is destroyed, all its children are
873 * - Insertion in DOM.
875 * Guide to create implementations of the Widget class:
876 * ==============================================
878 * Here is a sample child class:
880 * MyWidget = openerp.base.Widget.extend({
881 * // the name of the QWeb template to use for rendering
882 * template: "MyQWebTemplate",
883 * // identifier prefix, it is useful to put an obvious one for debugging
884 * identifier_prefix: 'my-id-prefix-',
886 * init: function(parent) {
887 * this._super(parent);
888 * // stuff that you want to init before the rendering
890 * start: function() {
891 * // stuff you want to make after the rendering, `this.$element` holds a correct value
892 * this.$element.find(".my_button").click(/* an example of event binding * /);
894 * // if you have some asynchronous operations, it's a good idea to return
895 * // a promise in start()
896 * var promise = this.rpc(...);
901 * Now this class can simply be used with the following syntax:
903 * var my_widget = new MyWidget(this);
904 * my_widget.appendTo($(".some-div"));
906 * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
907 * DOM inside the ".some-div" div and its events were binded.
909 * And of course, when you don't need that widget anymore, just do:
913 * That will kill the widget in a clean way and erase its content from the dom.
915 openerp.web.Widget = openerp.web.CallbackEnabled.extend(/** @lends openerp.web.Widget# */{
917 * The name of the QWeb template that will be used for rendering. Must be
918 * redefined in subclasses or the default render() method can not be used.
924 * The prefix used to generate an id automatically. Should be redefined in
925 * subclasses. If it is not defined, a generic identifier will be used.
929 identifier_prefix: 'generic-identifier-',
931 * Tag name when creating a default $element.
936 * Constructs the widget and sets its parent if a parent is given.
938 * @constructs openerp.web.Widget
939 * @extends openerp.web.CallbackEnabled
941 * @param {openerp.web.Widget} parent Binds the current instance to the given Widget instance.
942 * When that widget is destroyed by calling stop(), the current instance will be
943 * destroyed too. Can be null.
944 * @param {String} element_id Deprecated. Sets the element_id. Only useful when you want
945 * to bind the current Widget to an already existing part of the DOM, which is not compatible
946 * with the DOM insertion methods provided by the current implementation of Widget. So
947 * for new components this argument should not be provided any more.
949 init: function(parent, /** @deprecated */ element_id) {
