824 * Base class for all visual components. Provides a lot of functionalities helpful
825 * for the management of a part of the DOM.
828 * - Rendering with QWeb.
829 * - Life-cycle management and parenting (when a parent is destroyed, all its children are
831 * - Insertion in DOM.
833 * Guide to create implementations of the Widget class:
834 * ==============================================
836 * Here is a sample child class:
838 * MyWidget = openerp.base.Widget.extend({
839 * // the name of the QWeb template to use for rendering
840 * template: "MyQWebTemplate",
841 * // identifier prefix, it is useful to put an obvious one for debugging
842 * identifier_prefix: 'my-id-prefix-',
844 * init: function(parent) {
845 * this._super(parent);
846 * // stuff that you want to init before the rendering
848 * start: function() {
849 * // stuff you want to make after the rendering, `this.$element` holds a correct value
850 * this.$element.find(".my_button").click(/* an example of event binding * /);
852 * // if you have some asynchronous operations, it's a good idea to return
853 * // a promise in start()
854 * var promise = this.rpc(...);
859 * Now this class can simply be used with the following syntax:
861 * var my_widget = new MyWidget(this);
862 * my_widget.appendTo($(".some-div"));
864 * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
865 * DOM inside the ".some-div" div and its events were binded.
867 * And of course, when you don't need that widget anymore, just do:
871 * That will kill the widget in a clean way and erase its content from the dom.
873 openerp.web.Widget = openerp.web.CallbackEnabled.extend(/** @lends openerp.web.Widget# */{
875 * The name of the QWeb template that will be used for rendering. Must be
876 * redefined in subclasses or the default render() method can not be used.
882 * The prefix used to generate an id automatically. Should be redefined in
883 * subclasses. If it is not defined, a generic identifier will be used.
887 identifier_prefix: 'generic-identifier-',
889 * Tag name when creating a default $element.
894 * Constructs the widget and sets its parent if a parent is given.
896 * @constructs openerp.web.Widget
897 * @extends openerp.web.CallbackEnabled
899 * @param {openerp.web.Widget} parent Binds the current instance to the given Widget instance.
900 * When that widget is destroyed by calling stop(), the current instance will be
901 * destroyed too. Can be null.
902 * @param {String} element_id Deprecated. Sets the element_id. Only useful when you want
903 * to bind the current Widget to an already existing part of the DOM, which is not compatible
904 * with the DOM insertion methods provided by the current implementation of Widget. So
905 * for new components this argument should not be provided any more.
907 init: function(parent, /** @deprecated */ element_id) {
909 this.session = openerp.connection;
910 // if given an element_id, try to get the associated DOM element and save
911 // a reference in this.$element. Else just generate a unique identifier.
912 this.element_id = element_id;
913 this.element_id = this.element_id || _.uniqueId(this.identifier_prefix);
914 var tmp = document.getElementById(this.element_id);
