9 * @class Roo.bootstrap.Tooltip
10 * Bootstrap Tooltip class
11 * This is basic at present - all componets support it by default, however they should add tooltipEl() method
12 * to determine which dom element triggers the tooltip.
14 * It needs to add support for additional attributes like tooltip-position
18 * @param {Object} config The config object
21 Roo.bootstrap.Tooltip = function(config){
22 Roo.bootstrap.Tooltip.superclass.constructor.call(this, config);
25 Roo.apply(Roo.bootstrap.Tooltip, {
27 * @function init initialize tooltip monitoring.
