I am trying to get it to where if the user selects new it will change
the panel, but it isn't working at all. Nothing changes, but I know
the event method is getting called, because of a print statment.

[code]
private void jMenuItemNewActionPerformed(java.awt.event.ActionEvent
evt) {
        java.awt.CardLayout cl = (CardLayout)jPanelMain.getLayout();
        String path = "jPanelPagePageWelcome";
        cl.show(jPanelMain,path);
        System.out.println(path);
    }
[/code]
That is where I try to use the cardlayout. The rest of the code is
below
