* in it, each of which need a Tooltip which contains information specific
* to that element. For example:
var myGrid = new Ext.grid.gridPanel(gridConfig);
myGrid.on('render', function(grid) {
var store = grid.getStore(); // Capture the Store.
var view = grid.getView(); // Capture the GridView.
myGrid.tip = new Ext.ToolTip({
target: view.mainBody, // The overall target element.
delegate: '.x-grid3-row', // Each grid row causes its own seperate show and hide.
trackMouse: true, // Moving within the row should not hide the tip.
renderTo: document.body, // Render immediately so that tip.body can be
// referenced prior to the first show.
listeners: { // Change content dynamically depending on which element
// triggered the show.
beforeshow: function updateTipBody(tip) {
var rowIndex = view.findRowIndex(tip.triggerElement);
tip.body.dom.innerHTML = 'Over Record ID ' + store.getAt(rowIndex).id;
