CardLayout showing blank JPanel in Java

I've searched up different tutorials and looked at the Class Profile for CardLayout and JPanel but I can't seem to get my window to show up. Currently it opens a frame with the proper dimensions and title but nothing in the actual container.
This is the code I have(P.S. I know it's a hot mess)
import java.awt.CardLayout;
import java.awt.Color;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;

public class Casino extends JFrame implements ActionListener {
private JButton start, settings, scenario, music;
/**
* Constructor method
*/
public Casino(){
JPanel mainUI, startUI, settingsUI, scenarioUI, blackjackUI, oddorevenUI, tcmUI, overorunderUI, slotsUI;
JPanel menus = new JPanel(new CardLayout());
CardLayout GUI = (CardLayout) menus.getLayout();
mainUI = new JPanel();
getContentPane().add(mainUI);
mainUI.setBackground(new Color(53, 9, 9));
//Background items
JLabel title = new JLabel(new ImageIcon("title.png"));
title.setBounds(0,-280,780,700);
mainUI.add(title);
JLabel border = new JLabel(new ImageIcon("mainscreenborder.png"));
border.setBounds(0, 180, 780, 700);
mainUI.add(border);
//Main menu buttons
settings = new JButton();
ImageIcon s = new ImageIcon("settings-button.png");
settings.setBounds(320, 200, 122, 63);
settings.setIcon(s);
mainUI.add(settings);
music = new JButton();
ImageIcon m = new ImageIcon("music-button.png");
music.setBounds(320, 268, 122, 63);
music.setBackground(new Color(53, 9, 9));
music.setIcon(m);
mainUI.add(music);
scenario = new JButton();
ImageIcon sc = new ImageIcon("scenario-button.png");
scenario.setBounds(320, 336, 122, 63);
scenario.setBackground(new Color(53, 9, 9));
scenario.setIcon(sc);
mainUI.add(scenario);
start = new JButton();
ImageIcon st = new ImageIcon("start-button.png");
start.setBounds(320, 404, 122, 63);
start.setBackground(new Color(53, 9, 9));
start.setIcon(st);
mainUI.add(start);
menus.add(mainUI, "Main Menu");
GUI.show(menus, "Main Menu");
setSize(780, 700);
setResizable(false);
setLayout(GUI);
setTitle("White Lily Casino");
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
}
public void actionPerformed(ActionEvent e){
}
public static void main(String[] args) {
// TODO Auto-generated method stub
Casino wlc = new Casino();
}
}
Note: It worked before when I was using the Container c method instead of using a JPanel and CardLayout. I am trying to switch it to card layout now because I want to use buttons to navigate to multiple screens

Try adding the mainUI to the JFrame
getContentPane().add(mainUI)
or
add(mainUI)

JTree refresh without collapsing

I have a problem when refreshing a JTree instance. See the following code:
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.GroupLayout;
import javax.swing.GroupLayout.Alignment;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTree;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
public class ItemTest {
private JFrame frame;
private DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
private JTree tree = new JTree(root);
private JButton button = new JButton("Rebuild");
private String[] array = new String[] { "name", "first_name", "middle_name", "last_name"};
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
try {
ItemTest window = new ItemTest();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public ItemTest() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 523, 349);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JScrollPane scrollBar = new JScrollPane();
GroupLayout groupLayout = new GroupLayout(frame.getContentPane());
groupLayout.setHorizontalGroup(
groupLayout.createParallelGroup(Alignment.LEADING)
.addGroup(groupLayout.createSequentialGroup()
.addContainerGap()
.addComponent(scrollBar, GroupLayout.PREFERRED_SIZE, 200, GroupLayout.PREFERRED_SIZE)
.addComponent(button, GroupLayout.PREFERRED_SIZE, 85, GroupLayout.PREFERRED_SIZE)
.addContainerGap(412, Short.MAX_VALUE))
);
groupLayout.setVerticalGroup(
groupLayout.createParallelGroup(Alignment.LEADING)
.addGroup(groupLayout.createSequentialGroup()
.addGap(22)
.addComponent(scrollBar, GroupLayout.DEFAULT_SIZE, 278, Short.MAX_VALUE)
.addComponent(button, GroupLayout.DEFAULT_SIZE, 25, Short.MAX_VALUE)
.addContainerGap())
);
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
root.add(new DefaultMutableTreeNode("Row 4"));
((DefaultTreeModel) tree.getModel()).nodeChanged(root);
}
});
for(String string : array) {
root.add(new DefaultMutableTreeNode(string));
}
scrollBar.setViewportView(tree);
frame.getContentPane().setLayout(groupLayout);
}
}
If we run this code, and expand the "Root" node. We will see 4 nodes in it. If we click the button "Rebuild", the tree won't update it's self. The weird thing is, if we don't expand the "Root" node at the begin (so just start the application) and click the button, and after that we expand the "Root" node, the new row is added. Does anyone knows how to refresh this tree without collapsing, because nodeChanged doesn't seem to work when you expand the "Root" node at the begin.
Note: I have to accomplish this without using insertNodeInto.

You must notify the listeners that a node was inserted:
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
root.add(new DefaultMutableTreeNode("Row 4"));
((DefaultTreeModel) tree.getModel()).nodesWereInserted(
root, new int[]{root.getChildCount()-1});
}
});

How can i change jtextfield border after 5 seconds?

I try to change jtextfield border after 5 seconds. But doesnt work. My code:
// Here vaildate a field and set border to red
if (ApplicationNameField.getText().equals("")) {
Border newBorder = BorderFactory.createLineBorder(Color.RED, 1);
ApplicationNameField.setBorder(newBorder);
ErrorCode.setText("Error field cant be empty");
}
if (ApplicationHostField.getText().equals("")) {
Border newBorder = BorderFactory.createLineBorder(Color.RED, 1);
ApplicationHostField.setBorder(newBorder);
ErrorCode.setText("Error field cant be empty");
}
// here i would change border to start normal color (color black)
try {
TimeUnit.SECONDS.sleep(5);
Border newBorder = BorderFactory.createLineBorder(Color.BLACK, 1);
ApplicationNameField.setBorder(newBorder);
Border newBorder2 = BorderFactory.createLineBorder(Color.BLACK, 1);
ApplicationHostField.setBorder(newBorder2);
} catch (InterruptedException ex) {
System.out.print(ex.getMessage());
}
After this code my JTextFields borders are black and is not colored by red color.
Also i tried with:
Thread.sleep(5000);
But effect is the same. Anyone could help?

You need to use a javax.swing.Timer to trigger the desired action after 5 seconds. Thread.wait (or any other kind of waiting) doesn't work as expected because nothing is drawn until the thread returns to the main event loop.

Agree with #ammoQ. Just provide you an example of the use of javax.swing.Timer.
import java.awt.BasicStroke;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.Timer;
import javax.swing.border.AbstractBorder;
import javax.swing.border.EmptyBorder;
import javax.swing.border.LineBorder;
public class TimerTest implements ActionListener{
JTextField textField;
public void createUI(){
JFrame frame = new JFrame("Timer Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
MainPanel mainPanel = new MainPanel();
mainPanel.setBorder(BorderFactory.createEmptyBorder(5, 10, 5, 10));
frame.add(mainPanel,BorderLayout.CENTER);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
Timer timer = new Timer(5 * 1000, this);
timer.start();
}
public static void main(String[] args) {
TimerTest timerTest = new TimerTest();
timerTest.createUI();
}
#SuppressWarnings("serial")
class MainPanel extends JPanel{
public MainPanel(){
textField = new JTextField();
textField.setColumns(30);
textField.setBorder(BorderFactory.createCompoundBorder(
new LineBorder(Color.red, 3),
new EmptyBorder(new Insets(15, 25, 15, 25))));
add(textField,BorderLayout.CENTER);
setBackground(new Color(211,211,211));
setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
}
}
#Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
textField.setBorder(BorderFactory.createCompoundBorder(
new LineBorder(Color.black, 3),
new EmptyBorder(new Insets(15, 25, 15, 25))));
}
}

you can use SwingWorker to do this. see my running example below.

public static void main(String[] args) {

try {
JTextFieldTest frame = new JTextFieldTest();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**

public JTextFieldTest() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 298, 220);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
textField = new JTextField();
textField.setColumns(10);
textField.setBorder(BorderFactory.createLineBorder(Color.RED));
SwingWorker<Void, Void> worker = new SwingWorker<Void, Void>() {
#Override
protected Void doInBackground() throws Exception {
// Simulate doing something useful.
Thread.sleep(5000);
textField.setBorder(BorderFactory.createLineBorder(Color.BLACK));
return null;
}
};
worker.execute();
GroupLayout gl_contentPane = new GroupLayout(contentPane);
gl_contentPane.setHorizontalGroup(gl_contentPane.createParallelGroup(
Alignment.LEADING).addGroup(
gl_contentPane
.createSequentialGroup()
.addGap(87)
.addComponent(textField, GroupLayout.PREFERRED_SIZE,

.addContainerGap(99, Short.MAX_VALUE)));
gl_contentPane.setVerticalGroup(gl_contentPane.createParallelGroup(

you have to set proper LayoutManager in the case that you want to use JLabel as container (Grid or FlowLayout)
don't to use NullLayout
JTextArea isn't designated to be a container remove DATABASE_FIELD.setLayout(new GridLayout(3, 3));
use JTextArea (10, 15) as intial size instead of any sizing (then valid for JScrollPane too)
add JScrollPane with JTextArea to JFrames CENTER area or to change JLabels LayoutManager to BorderLayout, then to put JButtons to another separate JLabel (Grid or FlowLayout)
setTitle("Hospital Management");
setSize(900,600);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
to move those code lines to the end of constructor, then remove validate, as aside should be revalidate() and repaint(), becuase you didn't stop for Image repainting
call pack() instead of setSize

How to close main frame when open new one

Ive created two frames my main frame is Home and the second one is Selectie
On home there is a button which open the frame selectie, but i want when i click this button the main frame home wil dissapear and only selectie will be shown. The code for the button ive make in a other package and i dont want it in the same class as my main (home)
Code from Home:

I'd suggest to use CardLayout, most easiest, very confortable for (+1 for SSCCE) your code posted here
never create, re_create bunch of another JFrames, only in the cases that you have got very important reasons, then use JDialog with parent to the JFrame
