+ /** + * ToolTip is a {@link Ext.tip.Tip} implementation that handles the common case of displaying a + * tooltip when hovering over a certain element or elements on the page. It allows fine-grained + * control over the tooltip's alignment relative to the target element or mouse, and the timing + * of when it is automatically shown and hidden. + * + * This implementation does **not** have a built-in method of automatically populating the tooltip's + * text based on the target element; you must either configure a fixed {@link #html} value for each + * ToolTip instance, or implement custom logic (e.g. in a {@link #beforeshow} event listener) to + * generate the appropriate tooltip content on the fly. See {@link Ext.tip.QuickTip} for a more + * convenient way of automatically populating and configuring a tooltip based on specific DOM + * attributes of each target element. + * + * # Basic Example + * + * var tip = Ext.create('Ext.tip.ToolTip', { + * target: 'clearButton', + * html: 'Press this button to clear the form' + * }); + * + * {@img Ext.tip.ToolTip/Ext.tip.ToolTip1.png Basic Ext.tip.ToolTip} + * + * # Delegation + * + * In addition to attaching a ToolTip to a single element, you can also use delegation to attach + * one ToolTip to many elements under a common parent. This is more efficient than creating many + * ToolTip instances. To do this, point the {@link #target} config to a common ancestor of all the + * elements, and then set the {@link #delegate} config to a CSS selector that will select all the + * appropriate sub-elements. + * + * When using delegation, it is likely that you will want to programmatically change the content + * of the ToolTip based on each delegate element; you can do this by implementing a custom + * listener for the {@link #beforeshow} event. Example: + * + * var store = Ext.create('Ext.data.ArrayStore', { + * fields: ['company', 'price', 'change'], + * data: [ + * ['3m Co', 71.72, 0.02], + * ['Alcoa Inc', 29.01, 0.42], + * ['Altria Group Inc', 83.81, 0.28], + * ['American Express Company', 52.55, 0.01], + * ['American International Group, Inc.', 64.13, 0.31], + * ['AT&T Inc.', 31.61, -0.48] + * ] + * }); + * + * var grid = Ext.create('Ext.grid.Panel', { + * title: 'Array Grid', + * store: store, + * columns: [ + * {text: 'Company', flex: 1, dataIndex: 'company'}, + * {text: 'Price', width: 75, dataIndex: 'price'}, + * {text: 'Change', width: 75, dataIndex: 'change'} + * ], + * height: 200, + * width: 400, + * renderTo: Ext.getBody() + * }); + * + * grid.getView().on('render', function(view) { + * view.tip = Ext.create('Ext.tip.ToolTip', { + * // The overall target element. + * target: view.el, + * // Each grid row causes its own seperate show and hide. + * delegate: view.itemSelector, + * // Moving within the row should not hide the tip. + * trackMouse: true, + * // Render immediately so that tip.body can be referenced prior to the first show. + * renderTo: Ext.getBody(), + * listeners: { + * // Change content dynamically depending on which element triggered the show. + * beforeshow: function updateTipBody(tip) { + * tip.update('Over company "' + view.getRecord(tip.triggerElement).get('company') + '"'); + * } + * } + * }); + * }); + * + * {@img Ext.tip.ToolTip/Ext.tip.ToolTip2.png Ext.tip.ToolTip with delegation} + * + * # Alignment + * + * The following configuration properties allow control over how the ToolTip is aligned relative to + * the target element and/or mouse pointer: + * + * - {@link #anchor} + * - {@link #anchorToTarget} + * - {@link #anchorOffset} + * - {@link #trackMouse} + * - {@link #mouseOffset} + * + * # Showing/Hiding + * + * The following configuration properties allow control over how and when the ToolTip is automatically + * shown and hidden: + * + * - {@link #autoHide} + * - {@link #showDelay} + * - {@link #hideDelay} + * - {@link #dismissDelay} + * + * @docauthor Jason Johnston <jason@sencha.com> + */ +Ext.define('Ext.tip.ToolTip', { + extend: 'Ext.tip.Tip', + alias: 'widget.tooltip', + alternateClassName: 'Ext.ToolTip', + /** + * @property {HTMLElement} triggerElement + * When a ToolTip is configured with the `{@link #delegate}` + * option to cause selected child elements of the `{@link #target}` + * Element to each trigger a seperate show event, this property is set to + * the DOM element which triggered the show. + */ + /** + * @cfg {HTMLElement/Ext.Element/String} target + * The target element or string id to monitor for mouseover events to trigger + * showing this ToolTip. + */ + /** + * @cfg {Boolean} [autoHide=true] + * True to automatically hide the tooltip after the + * mouse exits the target element or after the `{@link #dismissDelay}` + * has expired if set.
