How to add cancel option to a splashscreen

Hello All,

I have a search screen and when I click the search button, I will have a splash screen coming with the following message.

var splash = Ext.getBody().mask('Retrieving data..This may take a few moments..', 'splashscreen');

Ext.suspendLayouts();

I would like to know if there is a way I can add a cancel option to this message so that when a user clicks on that cancel option, the whole search should stop. In case the user feels that the search is taking too long, he/she will click on that cancel option and the search will stop.

Is there a way to do this. Thanks in advance....
