问题 I've got 3 windows in 3 separate classes and I would like to use cardLayout so that when you click the next button, the next window will appear. How do I add JPanels containing different elements to one cardLayout? This is the first window: (the only difference is the background though - but it represents the idea of how I got it actually) public class Window1 extends JPanel implements ActionListener { static CardLayout cardLayout = new CardLayout(); public Window1() { init(); } private void

Can anyone throw some light on how to correctly refresh the whole panel? 回答1: This works fine for me. But

问题 I have to make a game for a school project in CS. I want to make it so that a person may input their name and all subsequent panels will have their name on it. I am using a card layout, which works for the most part. When I run the game and input the name, it works specifically on that card. However, when I go to the next card, where the String name is supposed to appear, it appears as null. My suspicion is that the program creates all of the cards before given the chance to accept the name

I am able to successfully read from the file and display data to the GUI. I've run into 2 problems and I've tried searching online for answers but cant seem to figure it out: 1) How do I get the JPanels to

问题 I want to change the JPanel of a JFrame, using the CardLayout class. I have already run this example and it works. Now I want to use as action listener, the JMenuItem; so If I press that JMenuItem, I want to change it, with a specific panel. So this is the JFrame: public class FantaFrame extends JFrame implements Observer { private static final long serialVersionUID = 1L; private JPanel cardPanel = new JPanel(); private CardLayout cardLayout = new CardLayout(); public FantaFrame(HashMap

问题 I am new to working with Java GUI, I know this may sound ridiculous but I have been trying for days to pass data between cards on the CardLayout layout. I am using netbeans, the first card displays a list clients. When a client is selected, the choice selection is passed to a variable on that card. The next card queries the database to show more details about the client selected. I can handle the switching between cards but my problem is I can't pass the data stored in the variable on card 1

问题 I'm trying to get a user to input a name in one panel on CardLayout and for the input to then define a JLabels text in the next panel that it switches to. I used System.out.println(userName); to double check that it was picking up the text and it definitely is but I don't know how to get the 'user' text to be that of the JTextFields input.
