I've been working with ExtJs for about 6 months now (I realize I still have plenty to learn ), and I'm attempting to develop my own application that will automate some data entry-type processes on the web.

1. Accessing Google gmail page
2. Create a new gmail account with data from application form
3. Fills out fields on the web page...
4. etc.

Now, my application already consists of a Viewport with west region as a control panel of sorts and the center region as a fully functional mini web browser that allows you input urls, go back and forth, etc.

I guess my question is "I don't have any idea about accessing the fields (text fields, buttons, links) on the loaded pages in my iframe. Could someone please point me in the right direction or at least let me know what I should be researching to achieve my application?"

I would really appreciate it
