/** * @class Ext.event.Event * @extend Ext.Base * * Just as {@link Ext.dom.Element} wraps around a native DOM node, {@link Ext.event.Event} * wraps the browser's native event-object normalizing cross-browser differences such as * mechanisms to stop event-propagation along with a method to prevent default actions * from taking place. * * ## Recognizers * * Ext JS includes many default event recognizers to know when a user interacts with * the application. * * For a full list of default recognizers, and more information, please view the * {@link Ext.event.gesture.Recognizer} documentation. * * This class also provides a set of constants for use with key events. These are useful * for determining if a specific key was pressed, and are available both on instances, * and as static properties of the class. The following two statements are equivalent: * * if (e.getKey() === Ext.event.Event.TAB) { * // tab key was pressed * } * * if (e.getKey() === e.TAB) { * // tab key was pressed * } */ /** * @property {Number} distance * The distance of the event. * * **This is only available when the event type is `swipe` and `pinch`.** */ /** * @property {HTMLElement} target * The element that fired this event. For the element whose handlers are currently * being processed, i.e. the element that the event handler was attached to, use * `currentTarget` */ /** * @property {HTMLElement} currentTarget * Refers to the element the event handler was attached to, vs the `target`, which is * the actual element that fired the event. For example, if the event bubbles, the * `target` element may be a descendant of the `currentTarget`, as the event may * have been triggered on the `target` and then bubbled up to the `currentTarget` * where it was handled. */ /** * @property {Number} button * Indicates which mouse button caused the event for mouse events, for example * `mousedown`, `click`, `mouseup`: * - `0` for left button. * - `1` for middle button. * - `2` for right button. * * *Note*: In IE8 & IE9, the `click` event does not provide the button. */ /** * @property {Number} pageX The browsers x coordinate of the event. * Note: this only works in browsers that support pageX on the native browser event * object (pageX is not natively supported in IE9 and earlier). In Ext JS, for a * cross browser normalized x-coordinate use {@link #getX} */ /** * @property {Number} pageY The browsers y coordinate of the event. * Note: this only works in browsers that support pageY on the native browser event * object (pageY is not natively supported in IE9 and earlier). In Ext JS, for a * cross browser normalized y-coordinate use {@link #getY} */ /** * @property {Boolean} ctrlKey * True if the control key was down during the event. * In Mac this will also be true when meta key was down. */ /** * @property {Boolean} altKey * True if the alt key was down during the event. */ /** * @property {Boolean} shiftKey * True if the shift key was down during the event. */ /** * @property {Event} browserEvent * The raw browser event which this object wraps. */ /** * @property {String} pointerType * The pointer type for this event. May be empty if the event was * not triggered by a pointer. Current available types are: * - `mouse` * - `touch` * - `pen` */ /** * @property {Boolean} [defaultPrevented=false] * Indicates whether or not {@link #preventDefault preventDefault()} was called on the event. */ /** * @property WHEEL_SCALE * The mouse wheel delta scaling factor. This value depends on browser version and OS and * attempts to produce a similar scrolling experience across all platforms and browsers. * * To change this value: * * Ext.event.Event.prototype.WHEEL_SCALE = 72; * * @type Number */
