i have a gui, with a panel and some buttons (not on the panel). i am building with boa constructor. my question is, how do i get different panels to show in my main frame on the click of different buttons. i know how to make things happens when you click on buttons - you just put code in the method associated with the button - buti am not quite sure how to change different panels - would it be a case of one class per panel - also how would incorporate all the different widgets in each panel?


thanks.
