Answer 1

ExtJS 4+

Panel header is instance of Ext.panel.Header class so you can simply use down() method like this:

afterrender: function (panel) {
    var header = panel.down('header'),
        headerElement = header.getEl();
    headerElement.on('click', function () {
        alert('ok');
    });
}

Here is fiddle.

ExtJS 3

You can use header property of the panel, like this panel.header.getEl().
