/** * Ext.Widget is a light-weight Component that consists of nothing more than a template * Element that can be cloned to quickly and efficiently replicate many instances. * Ext.Widget is typically not instantiated directly, because the default template is * just a single element with no listeners. Instead Ext.Widget should be extended to * create Widgets that have a useful markup structure and event listeners. * * For example: * * Ext.define('MyWidget', { * extend: 'Ext.Widget', * * // The element template passed to Ext.Element.create() * element: { * reference: 'element', * listeners: { * click: 'onClick' * }, * children: [{ * reference: 'innerElement', * listeners: { * click: 'onInnerClick' * } * }] * }, * * constructor: function(config) { * // It is important to remember to call the Widget superclass constructor * // when overriding the constructor in a derived class. This ensures that * // the element is initialized from the template, and that initConfig() is * // is called. * this.callParent([config]); * * // After calling the superclass constructor, the Element is available and * // can safely be manipulated. Reference Elements are instances of * // Ext.Element, and are cached on each Widget instance by reference name. * Ext.getBody().appendChild(this.element); * }, * * onClick: function() { * // listeners use this Widget instance as their scope * console.log('element clicked', this); * }, * * onInnerClick: function() { * // access the innerElement reference by name * console.log('inner element clicked', this.innerElement); * } * }); * * @since 5.0.0 * @disable {DuplicateAlternateClassName} */Ext.define('Ext.Widget', { extend: 'Ext.Evented', xtype: 'widget', alternateClassName: 'Ext.Gadget', requires: [ 'Ext.dom.Element' ], mixins: [ 'Ext.mixin.Inheritable', 'Ext.mixin.Bindable', 'Ext.mixin.ComponentDelegation', 'Ext.mixin.Pluggable', 'Ext.mixin.Keyboard', 'Ext.mixin.Factoryable', 'Ext.mixin.Focusable', 'Ext.mixin.Accessible' ], isWidget: true, factoryConfig: { creator: null, defaultProperty: 'xtype', defaultType: 'component', typeProperty: 'xtype' }, /** * @property {Object} element * A configuration object for Ext.Element.create() that is used to create the Element * template. Subclasses should avoid overriding this property and instead add elements * using {@link #template}. * * Supports all the standard options of a Ext.Element.create() config and adds 3 * additional options: * * 1. `reference` - this option specifies a name for Element references. These * references names become properties of the Widget instance and refer to Ext.Element * instances that were created using the template: * * element: { * reference: 'element', * children: [{ * reference: 'innerElement' * }] * } * * After construction of a widget the reference elements are accessible as follows: * * var foo = new FooWidget(), * innerEl = foo.innerElement; // an Ext.Element that wraps the innerElement * * The reference attribute is optional, but all Widgets must have a `'element'` * reference on some element within the template (usually the outermost one). * * 2. `listeners` - a standard listeners object as specified by {@link Ext.mixin.Observable}. * * element: { * reference: 'element', * listeners: { * click: 'onClick' * }, * children: [{ * reference: 'innerElement', * listeners: { * click: 'onInnerClick' * } * }] * } * * Since listeners cannot be attached without an Ext.Element reference the `reference` * property MUST be specified in order to use `listeners`. * * The Widget instance is used as the scope for all listeners specified in this way, * so it is invalid to use the `scope` option in the `listeners` config since it will * always be overwritten using `this`. * * 3. `uiCls` - a suffix to be appended to the ui-specific CSS class for each `{@link #ui}` * for this widget. These ui classes are constructed by appending the `ui` to each * `{@link #classCls}` or `{@link #baseCls}` for the widget. As such, `uiCls` should * never be used on the main `element` reference, as its `uiCls` is computed automatically. * * For example, assume a widget is defined with a `ui` of `'alt action'` and a * `uiCls` of `'inner-el'` on its `innerElement` reference element: * * Ext.define('Doodad', { * extend: 'Ext.Widget', * xtype: 'doodad', * * classCls: 'x-doodad', * * ui: 'alt action', * * element: { * reference: 'element', * * children: [{ * reference: 'innerElement', * cls: 'x-inner-el', * uiCls: 'inner-el' * }] * } * }); * * This would result in the following markup when rendered: * * <div class="x-doodad x-doodad-alt x-doodad-action"> * <div class="x-inner-el x-doodad-inner-el x-doodad-alt-inner-el x-doodad-action-inner-el"></div> * </div> * * These additional classes can be used to style the reference element for a particular * ui; however, use of `uiCls` is not typically necessary or recommended. Reference * elements should usually be styled using simple descendant selectors: * * .x-doodad-alt .x-inner-el { * color: red; * } * * When there is a possibility that widgets can be nested it is best to use direct * child selectors to avoid the possibility of selecting all descendants instead * of just the reference element for the intended widget: * * .x-doodad-alt > .x-inner-el { * color: red; * } * * Only use `uiCls` when there is a possibility of nesting, AND there may be a variable * number of elements between the main `element` and the reference element in question. * For example, Ext.Container with docked items has a different number of elements * in between its `element` and its `bodyElement` than a Container without docked items * because of the wrapping elements that are dynamically added to support docking. * To ensure it does not style all descendants it must use a `uiCls` to style its * `bodyElement`: * * .x-container-alt-body-el { * background: #fff; * } * * Note that when `uiCls` is specified it also adds a class name that does not contain * the `ui` using just the `classCls` and/or `baseCls` as the prefix. This class name * can be used for base-level styling that does not relate to any particular UI: * * .x-container-body-el { * position: relative; * } * * @protected */ element: { reference: 'element' }, observableType: 'component', cachedConfig: { /** * @cfg {String/String[]} cls The CSS class to add to this widget's element, in * addition to the {@link #baseCls}.
