This is what I want:
when i click on one of the radio buttons (in the west panel), i want the center panel to display one of 3 cards. problem is, i can't seem to pull it off!
here's the code for that particular tab and the action listener method for it:

thanks in advance!

create some panel with a gridlayout (or layout of your choice)
create the 3 buttons, assign action listeners to them and add to the panel.

create ANOTHER panel ('cardPanel') and assign it with a CardLayout
Create 3 more different panels (you can add whatever components to these or make them whatever colours you want to distinguish them).

add your 3 unique panels to 'cardPanel' with the following
cardPanel.add(panel1,"panel1Identifier");
cardPanel.add(panel2,"panel2Identifier");
cardPanel.add(panel3,"panel3Identifier");

in each of your 3 action listeners for the 3 buttons do the following to call the appropriate form.
CardLayout cLay = cardPanel.getLayout();
cLay.show(cardPanel,"panel1Identifier");

keep in mind that you have to substitute the correct string identifier for the appropriate panel..
my method names might not be 100% correct (doing this quickly) , but you should be able to get the idea.
NOTE that with the show() method you are calling it on the layout manager and then giving the parent container as a parameter.
