10 * A standard tooltip implementation for providing additional information when hovering over a target element.
13 * Create a new Tooltip
14 * @param {Object} config The configuration options
16 Ext.ToolTip = Ext.extend(Ext.Tip, {
18 * When a Tooltip is configured with the <code>{@link #delegate}</code>
19 * option to cause selected child elements of the <code>{@link #target}</code>
20 * Element to each trigger a seperate show event, this property is set to
21 * the DOM element which triggered the show.
23 * @property triggerElement
26 * @cfg {Mixed} target The target HTMLElement, Ext.Element or id to monitor
27 * for mouseover events to trigger showing this ToolTip.
30 * @cfg {Boolean} autoHide True to automatically hide the tooltip after the
31 * mouse exits the target element or after the <code>{@link #dismissDelay}</code>
32 * has expired if set (defaults to true). If <code>{@link closable} = true</code>
33 * a close tool button will be rendered into the tooltip header.
36 * @cfg {Number} showDelay Delay in milliseconds before the tooltip displays
37 * after the mouse enters the target element (defaults to 500)
41 * @cfg {Number} hideDelay Delay in milliseconds after the mouse exits the
42 * target element but before the tooltip actually hides (defaults to 200).
43 * Set to 0 for the tooltip to hide immediately.
47 * @cfg {Number} dismissDelay Delay in milliseconds before the tooltip
48 * automatically hides (defaults to 5000). To disable automatic hiding, set
53 * @cfg {Array} mouseOffset An XY offset from the mouse position where the
54 * tooltip should be shown (defaults to [15,18]).
57 * @cfg {Boolean} trackMouse True to have the tooltip follow the mouse as it
58 * moves over the target element (defaults to false).
62 * @cfg {Boolean} anchorToTarget True to anchor the tooltip to the target
63 * element, false to anchor it relative to the mouse coordinates (defaults
64 * to true). When <code>anchorToTarget</code> is true, use
65 * <code>{@link #defaultAlign}</code> to control tooltip alignment to the
66 * target element. When <code>anchorToTarget</code> is false, use
67 * <code>{@link #anchorPosition}</code> instead to control alignment.
69 anchorToTarget : true,
71 * @cfg {Number} anchorOffset A numeric pixel value used to offset the
72 * default position of the anchor arrow (defaults to 0). When the anchor
73 * position is on the top or bottom of the tooltip, <code>anchorOffset</code>
74 * will be used as a horizontal offset. Likewise, when the anchor position
75 * is on the left or right side, <code>anchorOffset</code> will be used as
80 * @cfg {String} delegate <p>Optional. A {@link Ext.DomQuery DomQuery}
81 * selector which allows selection of individual elements within the
82 * <code>{@link #target}</code> element to trigger showing and hiding the
83 * ToolTip as the mouse moves within the target.</p>
84 * <p>When specified, the child element of the target which caused a show
85 * event is placed into the <code>{@link #triggerElement}</code> property
86 * before the ToolTip is shown.</p>
87 * <p>This may be useful when a Component has regular, repeating elements
88 * in it, each of which need a Tooltip which contains information specific
89 * to that element. For example:</p><pre><code>
90 var myGrid = new Ext.grid.gridPanel(gridConfig);
91 myGrid.on('render', function(grid) {
92 var store = grid.getStore(); // Capture the Store.
93 var view = grid.getView(); // Capture the GridView.
94 myGrid.tip = new Ext.ToolTip({
95 target: view.mainBody, // The overall target element.
96 delegate: '.x-grid3-row', // Each grid row causes its own seperate show and hide.
97 trackMouse: true, // Moving within the row should not hide the tip.
98 renderTo: document.body, // Render immediately so that tip.body can be
99 // referenced prior to the first show.
100 listeners: { // Change content dynamically depending on which element
101 // triggered the show.
102 beforeshow: function updateTipBody(tip) {
