cardlayout

问题 I have written a program which uses CardLayout. I want it to show a JPanel and then, based on the user's input, shows a new JPanel, pause for 3 seconds, and then show another JPanel which requires user input. My JPanel requiring user input works fine, and the debugging I've done has shown me that when the program pauses for 3 seconds, the "filler" panels (see below) are being generated, but just not rendered properly. class sylBetween extends JPanel{ sylBetween(boolean response, String

问题 So. I've made an application. It has a mainFrame which creates two panels, one holding my wizard-alike buttons (e.g. Next, Previous) and one cardLayout, enabling me to go to either next or previous panel, which I declare in the mainFrame. By having an interface, Verifiable, I'm able to override every window-class a isDataValid()-function which decides whether next and prev buttons should call for cardlayouts flip functions. The source code can be seen below: public class MainFrame { private

问题 I have a Swing application using Card Layout which basically changes the displayed panel depending on what the user selects from a drop-down menu. One of my panels has a form. I would need for when the submit buton is pressed for all the inputs to be collected and the Panel to be switched to another one. (This second panel is defined in a separate class) I would also need for all the input to be somehow passed to a method in the new panel. Any suggestions? Dario 回答1: If you look at the <-- s

问题 This post is continue of this post. Basically in my software is based on CardLayout panels. And now I want to change panels from outside of cardLayout . in the provided link, I got helped to do this and it worked. Now I added a controller to my software, that is between an inner panel ( CardLayout ) and an outside panel. In the outside panel( leftBar ) I have a button that if its actionListener is located inside that class it works correctly and open the chose inner panel of CardLayout . But

问题 I have a top-level GUI class called SpacePotaters (subclass of JFrame) and I add a JPanel called panelViews (which uses the CardLayout layout manager) to its content pane. Among other things, I add a MainMenu object (subclass of JPanel) and a GameView object (subclass of JPanel) as cards to panelView. public SpacePotaters(){ super("Space Potaters"); Container content = getContentPane(); // initialize components gameView = new GameView(this); mainMenu = new MainMenu(this); leaderboard = new

问题 I have an application that is a Maths Game for kids. Since I'm in college, I've usually only had a god object for all my past projects but for this applciation I've split my code into multiple classes: MathsGame.java : main class which initialises components and constructs and controls the UI. DiffScreen.java : contains methods for use on the difficulty selection screen. GameScreen.java : contains methods for use on the game screen. EndGameScreen.java : contains methods for use on the end

问题 I have two JPanels that I want to switch between when user clicks on them. So I created a Window with a JFrame in it. Then I create a JPanel called cards and set its layout to CardLayout . Then I create two more JPanel s - these are the panels that I want to switch between - and I add them to cards . I add mouseClicked event listeners and I add cardLayout.next(cards) so the switch will happen. It doesn't work. Here's my code: public class Window { private JFrame frame; private JPanel cards;

问题 I added my buttons in a JPanel (which has a border layout , added the buttons to its south position), then added another JPanel cardsPanel in the ( center position of the) parent panel, and gave it a CardLayout . I want this cardsPanel to be the container for the cards (I mean the panels which will share the same screen space). Now what I need to do is to to display those cards (I am calling the panels which will share the same screen space as cards) as a response to the buttons in the parent

问题 My software layout is kinda wizard-base. So the base panel is divided into two JPanel s. One left panel which never changes. And one right panel that works with CardLayout . It has many sub-panels and show each one of them by a method. I can easily go from one inner panel to another one. But I want to have a button in left panel and change panels of the right side. Here is a sample code which you can run it: BASE: public class Base { JFrame frame = new JFrame("Panel"); BorderLayout bl = new

问题 Can one component (e.g. a JLabel ) be in multiple cards using CardLayout ? Currently it seems that the component appears only at the last card it was added to. If there is a way to do this, should I? Is it bad practice? Or is there some alternative? 回答1: You are correct that it only appears in the "last card it was added to", but that has nothing to do with CardLayout , that has to do with the fact each component can only be in one parent.
