Problem<\/strong>
\nYou want to display a grid with a tooltip.<\/p>\n

Tested in ExtJS Version<\/strong>
\n4.1.1<\/p>\n

Screenshot<\/strong>
\n\"\"<\/a><\/p>\n

Solution<\/strong>
\nSet the “tip” property on the GridPanel’s view (panel.getView().tip).<\/p>\n

view = this.getView();\nview.tip = Ext.create('Ext.tip.ToolTip', {\n\ttarget: view.el,\n\tdelegate: view.itemSelector,\n\ttrackMouse: true,\n\trenderTo: Ext.getBody(),\n\tlisteners: {\n     \t\tbeforeshow: function updateTipBody(tip) {\n     \t\t\t tip.update(\"Tooltip!\");\n        }\n}<\/pre>\n
Discussion<\/strong>
\nThe example ExtJS provides in their documentation did not work for me. In their example, they run this code in a the render event, which they set after the grid object is created- for whatever reason this only works in afterrender.<\/p>\n
You can retrieve the highlighted row inside the beforeshow event using view.getRecord(tip.triggerElement), but it is not clear how to determine which column the tooltip is rendered on.<\/p>\n
See the ExtJS GridView example<\/a> for further discussion.<\/p>\n
