How to comunicate between two frames?

Hello:

I have a problem on comunicating between two frames. For example :

There is a textField A and a button A in Frame A. When I click the button A, it will pop up a Frame B. As Frame A, Frame B also have a textField B and a button B. On Frame B, I type some words in textField B. Then I click the button B to close Frame B. I want the textFiled A on Frame A can get the words typed in textField B.

Could you please help me to reslove this problem?

Thank you very much.
