you can do like this

{
xtype: 'combo'
listeners: {
'select': function(t){ alert(t.value); }
}

You can have a listener as below:-

var applicationCombo = new Ext.form.ComboBox({
store: ['Application 1', 'Application 2', 'Application 3'],
listeners: {
'select': function(combo, record,...

I'm using ExtJS 4.
This code works for me... I can switch between panel using getLayout()...
Moreover, getLayout() is returning an object in my code...
I dont know whats wrong with this one

You can try this:

var X = e.browserEvent.clientX;
var Y = e.browserEvent.clientY;
this.digitizer.menu.showAt([X, Y]);
