Thread: Cardlayout help

Hello everyone I am quite new to Java swing so bare with me.

I am currently using the IDE netbeans 6.9. What I am trying to do is get a certain button to display a specific card from my card layout.

  @Action
    //action for button pan3
    public void changeIn() {
CardLayout cl = (CardLayout)(mainPanel.getLayout());
cl.show(mainPanel, card3);
    }

That is my code right there; as you can see I am using the cl.show method. I have 3 jpanels inside a cardlayout. jpanel 3 has a name of card3. As you can see I am trying to have this specific card to show on the click of a button. This code shows no error however when I compile it and click the button
nothing happens. Does anyone know how to get his to work?

Thanks for the help I am very new to swing.

If that doesn't help, boil your problem down to an SSCCE (that's a link) that demonstrates the problem without any extra code.
