function confirmClick() { 
Ext.Msg.confirm('Confirm','Choose one please',showOutput); 
} 
function promptClick() { 
Ext.Msg.prompt('Prompt', 'Try enter something', 
function(id, msg) { 
showOutput('You pressed ' + id + ' key and entered ' + msg); 
}); 
} 
function showClick() { 
var option = { 
title:'Box Show', 
msg: 'This is a most flexible messagebox with an info icon.', 
modal: true, 
buttons: Ext.Msg.YESNOCANCEL, 
icon: Ext.Msg.INFO, 
fn:showOutput 
}; 
Ext.Msg.show(option);
