hello, i am confused about how i can add a link to the following code
onReady: function() {
new Ext.TabPanel({
fullscreen: true,
type: 'dark',
sortable: true,
items: [{
title: 'Tab 1',
html: '1',
cls: 'card1'
to be able to directly load a url when i click the Tab 1. This code is from the sencha touch template. I want the htm part to be able to load a url when that tab is selected. thanks
