Moving from one frame to another

I am new to JAVA swing , where i develop two different JFrame if I click on button frame should move to another frame and previous frame should close by opening of next frame.
I click on button a next frame open but data inside frame is not displaying and previous frame is not closed on button . Please help to find the problem in code.
Frame 1:---------------------------------

For this problem, I think it's a fairly simple solution, as Andrew commented, you don't need to keep creating JFrames, you can create your JFrame in your first program, and pass it to your second class through the constructor.
Why I think your program is closing is because you are calling dispose() after creating the new frame which might be destroying the components in your new frame.
You could take this approach, which uses only one frame creating in the opening class and carried over to the second class
For Example (using snipplets of your code):
Frame 1
//This is where you are moving to the second frame.
if(e.getSource() == startButton)
{
mainFrame.getContentPane().removeAll(); //removeAll() method wipes all components attached to the contentpane of the frame
//Frame can be reused when passed to second class
TestjigWindow2 frame2 = new TestjigWindow2(this.mainFrame);
}
Frame 2
//In your constructor you could have something like this
private JFrame mainFrame;
/*
* Other variables and constants go here
*
*/
public TestjigWindow2(JFrame mainFrame)
{
this.mainFrame = mainFrame;
prepareGUI();
}
And then in prepareGUI(), you would then be adding your components to your frame, without creating a new frame. With this, your first page will be closed, and the second frame will be open, without you having to creating mutiple JFrames.

You should just create a new Instance of TestjigWindow2 in the actionPerformed method within your first frame. Instead of adding actionPerformed on the startbutton and stopbutton seperately, implement ActionListener interface in your Frame1 class and just keep one method since you are checking for the source inside the method anyways.
#Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
try
{
if(e.getSource() == startButton)
{
TestjigWindow2 frame2 = new TestjigWindow2();
//frame2.setVisible(true); do this inside the frame2 preparegui method
dispose();
}
else if(e.getSource() == closeButton)
{
System.exit(0);
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
});
Also the code will have a more generalized flow if you have the main method inside Frame1 and instantiate the Frame1 in it.
And you don't need to use setVisible inside the actionPerformed of Frame1.

Resetting toggle buttons

I am designing an elevator for my software engineering class. I am using toggle buttons on the elevator cars inside panel for floor selection. I cannot figure out how to toggle the button off if the current floor equals the button being toggled. I have included a code snippet.
package test;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JToggleButton;
import javax.swing.SwingUtilities;
public class test {
public JPanel createContentPane() {
// We create a bottom JPanel to place everything on.
JPanel totalGUI = new JPanel();
totalGUI.setLayout(null);
// Creation of a Panel to contain the buttons
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(null);
buttonPanel.setLocation(10, 80);
buttonPanel.setSize(500, 500);
totalGUI.add(buttonPanel);
final JToggleButton floor3 = new JToggleButton("3");
floor3.setSize(50, 50);
floor3.setLocation(68, 100);
buttonPanel.add(floor3);
floor3.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (3 == 3) {
AbstractButton abstractButton = (AbstractButton) e
.getSource();
boolean selected = abstractButton.getModel().isSelected();
System.out.println("Action - selected=" + selected + "\n");
floor3.setSelected(!selected);
// code to toggle the third floor button off
}
}
});
totalGUI.setOpaque(true);
return totalGUI;
}
static void createAndShowGUI() {
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("Elevator");
// Create and set up the content pane.
test Welp = new test();
frame.setContentPane(Welp.createContentPane());
frame.setSize(250, 500);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
// Schedule a job for the event-dispatching thread:
// creating and showing this application's GUI.
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}

JButton Wont Display JPanel

I want to call My JPanel with button. My Jpanel is actually a sub JPanel from main Panel with card layout.
to do that, i am using card layout api method HERE to show the JPanel after a button was clicked.
JButton btnCallPanel1 = new JButton("Call PanelOne");
btnCallPanel1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
CardLayout card = (CardLayout)mainPanel.getLayout();
card.show(mainPanel, "PanelOne"); //call Panel One
}
output :
nothing appear, panel not called and no error pop out.
My Code is HERE
package wan.dev.sample.cardlayout;
import java.awt.CardLayout;
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JLabel;
public class HowToUseCardLayout {
private JFrame frame;
/**

public void run() {
try {
HowToUseCardLayout window = new HowToUseCardLayout();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**

*/
public HowToUseCardLayout() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 688, 358);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JPanel mainPanel = new JPanel();
mainPanel.setBounds(0, 0, 672, 260);
frame.getContentPane().add(mainPanel);
mainPanel.setLayout(new CardLayout(0, 0));

JButton btnPan1 = new JButton("Call PanelOne");
btnPan1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
CardLayout card = (CardLayout) mainPanel.getLayout();
card.show(mainPanel, "PanelOne");
}
});
btnPan1.setBounds(262, 286, 144, 23);
frame.getContentPane().add(btnPan1);
}
}
ANSWER
The reason i cant call my panel because i did not call it by using identifier.
i have to give identifier name to my desire jpanel and use the identifier on my cardLayout.show(..)
Public Static final String PANEL_ONE = "panel one"; //Name of JPanel Identifier
//add panel to main panel and declare panelOne identifier
mainPanel.add(panelOne, PANEL_ONE); //PANEL_ONE function like
//an identifier
JButton btnCallPanel1 = new JButton("Call PanelOne");
btnCallPanel1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
CardLayout card =
(CardLayout)mainPanel.getLayout();
card.show(mainPanel, PANEL_ONE); //call panelOne using PANEL_ONE
//instead of JPanel name
}

As I suspected — You're calling the CardLayout.show(...) method with the String parameter "PanelOne", but yet you've not added any component to the CardLayout-using container using this same String, so it makes sense that it won't work. Solution: don't do this. Use the Same String that you add the component to the CardLayout using container as the one that you use to display it.
i.e., If you want to display container foo and use the String "bar" to add it to the CardLayout-using container, then you must pass "bar" into the CardLayout's show(...) method. Again, use String constants for this so that you reduce the chances of messing up.
Other issues: You're using null layout and setBounds — Don't. Doing this makes for very inflexible GUI's that while they might look good on one platform look terrible on most other platforms or screen resolutions and that are very difficult to update and maintain.
e.g.,
import java.awt.CardLayout;
import java.awt.event.ActionEvent;
import javax.swing.*;
public class CardLayoutFoo extends JPanel {
public static final String BAR = "bar";
public static final String BUTTON_PANEL = "button panel";
private CardLayout cardlayout = new CardLayout();
public CardLayoutFoo() {
setLayout(cardlayout);
JLabel fooLabel = new JLabel("Foo", SwingConstants.CENTER);
add(fooLabel, BAR); // added using String constant, BAR
JButton showFooBtn = new JButton(new AbstractAction("Show Foo") {
#Override
public void actionPerformed(ActionEvent evt) {
// use same String, BAR, to get the fooLabl shown
cardlayout.show(CardLayoutFoo.this, BAR);
}
});
JPanel btnPanel = new JPanel();
btnPanel.add(showFooBtn);
add(btnPanel, BUTTON_PANEL);
cardlayout.show(this, BUTTON_PANEL);
}
private static void createAndShowGui() {
CardLayoutFoo mainPanel = new CardLayoutFoo();
JFrame frame = new JFrame("CardLayoutFoo");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}

Do Operations on the same Object/List from different ActionListeners

I have this GUI setup. tl;dr is: its a gui and a MenuItem calls myActionListener.
There is also an Object o in this class.
I want this object o be accessible by the myActionListener as well as a myActionListener2 etc..
But i cant even call any of the Object methods.
public class MenuDemo implements ActionListener,ItemListener{
// My Object
Object o = new Object();
o.addParam();// wont work
public JMenuBar createMenuBar() {
JMenuBar menuBar;
JMenu menu, submenu;
JMenuItem menuItem;
menu = new JMenu("A Menu");
menuBar.add(menu);
menuItem = new JMenuItem("Title");
menuItem.addActionListener(new myListener());
menu.add(menuItem);
return menuBar;
}
public Container createContentPane() {
//Create the content-pane-to-be.
JPanel contentPane = new JPanel(new BorderLayout());
contentPane.setOpaque(true);
//Create a scrolled text area.
output = new JTextArea(5, 30);
output.setEditable(false);
scrollPane = new JScrollPane(output);
//Add the text area to the content pane.
contentPane.add(scrollPane, BorderLayout.CENTER);
return contentPane;
}
public Container createContentPane() {
//Create the content-pane-to-be.
JPanel contentPane = new JPanel(new BorderLayout());
contentPane.setOpaque(true);
//Create a scrolled text area.
output = new JTextArea(5, 30);
output.setEditable(false);
scrollPane = new JScrollPane(output);
//Add the text area to the content pane.
contentPane.add(scrollPane, BorderLayout.CENTER);
return contentPane;
}
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
Database db = new Database();
final int test = 5;
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
Ive been trying to figure this out for a while but it seems like i cant find any help or maybe im going at it in the wrong way?

As I said in comment, you can pass a reference of the Object to different objects of type/subtype of an ActionListener:
Main class:
import java.awt.EventQueue;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
public class Main extends JFrame
{
private JButton btn;
Object o;
public Main()
{
setLayout(new FlowLayout());
o = new String("Hello Beautiful!");
btn = new JButton("Click!");
//Passing the reference `o` to the constructor
btn.addActionListener(new JButtonListener(o));
add(btn);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
pack();
setLocationRelativeTo(null);
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable() {
public void run()
{
new Test1();
}
});
}
}
Class that implements ActionListener:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JOptionPane;
public class JButtonListener implements ActionListener
{
private Object _obj;
public JButtonListener(Object obj)
{
_obj = obj;
}
#Override
public void actionPerformed(ActionEvent e)
{
JOptionPane.showMessageDialog(null, _obj.toString());
}
}

Java EventHandling

When I compile it show error in line 33 : Cannot find symbol.
I am calling jbtNew.addActionListener(listener), so why it's unable to find jbtNew in
(e.getSource() == jbtNew) in line 33.
from code
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class AnonymousListenerDemo extends JFrame {
public AnonymousListenerDemo() {
// Create four buttons
JButton jbtNew = new JButton("New");
JButton jbtOpen = new JButton("Open");
JButton jbtSave = new JButton("Save");
JButton jbtPrint = new JButton("Print");
// Create a panel to hold buttons
JPanel panel = new JPanel();
panel.add(jbtNew);
panel.add(jbtOpen);
panel.add(jbtSave);
panel.add(jbtPrint);
add(panel);
// Create and register anonymous inner-class listener
AnonymousListenerDemo.ButtonListener listener = new AnonymousListenerDemo.ButtonListener();
jbtNew.addActionListener(listener);
}
class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
if (e.getSource() == jbtNew) //Here it show the problem
{
System.out.println("Process New");
}
}
}
/** Main method */
public static void main(String[] args) {
JFrame frame = new AnonymousListenerDemo();
frame.setTitle("AnonymousListenerDemo");
frame.setLocationRelativeTo(null); // Center the frame
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
}

That's a local variable.
It doesn't exist outside the constructor.
You need to make a field in the class.

this could be work (in the form as you posted here) and #SLaks mentioned +1, with a few major changes
in the case that all methods will be placed into separated classes to use put/getClientProperty()
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class AnonymousListenerDemo {
private static final long serialVersionUID = 1L;
private JFrame frame = new JFrame("AnonymousListenerDemo");
// Create four buttons
private JButton jbtNew = new JButton("New");
private JButton jbtOpen = new JButton("Open");
private JButton jbtSave = new JButton("Save");
private JButton jbtPrint = new JButton("Print");
public AnonymousListenerDemo() {
JPanel panel = new JPanel();// Create a panel to hold buttons
panel.add(jbtNew);
panel.add(jbtOpen);
panel.add(jbtSave);
panel.add(jbtPrint);
// Create and register anonymous inner-class listener
jbtNew.addActionListener(new ButtonListener());
frame.add(panel);
//frame.setTitle("AnonymousListenerDemo");
frame.setLocationRelativeTo(null); // Center the frame
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
if (e.getSource() == jbtNew) {
System.out.println("Process New");
}
}
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
new AnonymousListenerDemo();
}
});
}
}
