JLabel will not update/ display. Initialization Issue? - java

I know there are already many topics on this issue but I promise you I have exhausted the search.
At the opening of my application, the "ExampleGUI" window should display, when a Calendar button is clicked a Calendar Frame pops up and the user chooses a date, which is represented as a String. This string, along with some other information, is passed back to the ExampleGUI, as a new ExampleGUI. It will then go to the method updateDate, which should display the date that the user chose on the current frame, as a JLabel. However, no matter what I try, the JLabel will not display or will not update. I know about SetText, it's not currently included in my code but I have tried it and it doesn't work. I know it is passing the date correctly because System.out.println will work fine. If you have any help I will be forever grateful I am officially stumped.
UPDATE
Added the most pared down code I could make -- sorry the Calendar is so long, I couldn't take much out but I promise it is not the problem you just need it to run the GUI where the problem resides.
Thanks!

Your problem is here:
btnChoose.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int row = table.getSelectedRow();
int col = table.getSelectedColumn();
if (row == (-1) || col == (-1)) {
JOptionPane.showMessageDialog(null, "Please Select a Date",
"Error", JOptionPane.WARNING_MESSAGE);
} else {
returnDate(row, col);
GUI DS1 = new GUI(getFinalDate(), SoE); // *****************
dispose();
}
}
});
You are creating a new GUI object, one completely distinct from the currently displayed GUI instance.
suggestions:
The new window should not be a JFrame but should be a modal JDialog. If it is a modal dialog, it will freeze the calling code from the point that it is set visible, and then that code will resume flow once the dialog is no longer visible.
Set this dialog visible from the original class, the GUI's ActionListener.
Don't have Calndar object change anything in GUI. Rather in its action listener store the selected date (if anything is selected) in a field, and dispose of the dialog.
Then the calling class, here GUI can query the Calndar object once it is no Calndar is longer visible, within GUI's select ActionListener, but after Calndar is set visible, and extract the selected date by calling a public getter method on the Calndar object.
Then GUI can use this information to update its visualized data.
Call revalidate and repaint after adding or removing components from a running GUI.
In the future, try to use only 1 file for your example program.

Also:
I wouldn't add a JLabel when adding the date in the main GUI. Rather I'd create a JLabel field, add it to the GUI initially, and then simply set its text when the need arises.

JTable not updating/refreshing when new model is set with data

Hey so I have a problem with my JTable where it is not updating the table when I set its model to a new one with data within it. I have checked and all the arrays have data values within them, coming from another class. The cData array has all the right strings and values. But it doesnt seem to update.

Java JDialog Passing Object From Within the JDialog using a Sumbit Button from the JDialog

ive searched online for the answer for a few hours now, so far i havent found anything helpful, i have a JDialog that is supposed to send an object back to the JPanel that called it, after running the code several times i noticed that the JPanel Constructor Finishes before i can press the Save button inside the JDialog,

how do i pass the object from the JDialog to the JPanel and in which part of the Jpanel Code do i write it?

So in short in the JDialog i need to get information from comboboxes and texfields and send that data to an object constructor, and on the "Save" button click i need to transfer the Object from the JDialog that i created with the constructor to the JPanel, how do i do it?
i realized i can send the JPanel to the JDialog and in the JDialog's code where i create the object, i modify the Jpanel's Hashset accordingly

JInternalFrame does not show up

from my MainFrame I create a internal Frame and add that to my desktop pane, but the internal Frame just won't show up. I tried to figure it out for 3 hours now and I kinda need some help with it. Before I implemented the observer pattern it just worked fine. So I thought it got something to do with that and changed some stuff and double checked the crucial code. No solution so far. I just realized how crappy my english is sometimes. Sorry for that!
The 2 code blocks are already shortened. Sorry that they are still pretty long. But I am just not sure where I made the mistake. If you need more code or anything else, just tell me. Thank you very much in advance.
This is the code of my main frame:

I think it is because you didn't set size for your JInternalFrame. In your code it is as a comment:
//kind.setSize(370, 370);
when I remove "//" it works for me.

Application not displaying GUI and won't quit Java

So I'm creating a game in Java and I ran into a little problem. Whenever I run the application the GUI does not show on the screen and the only way to close the application is to use the Windows Task Manager. In the application, you choose a username and click an enter button which creates a new window in which the game is played. But after you click the button, none of the GUI loads and you can't close the application.
Basically, when you click the button, a method is called that disposes the current window and starts the game window. The code for that method is below:
public void login(String name) {
String[] args={};
dispose();
SingleplayerGUI.main(args);
}
And here is the code of the SingleplayerGUI class:
public SingleplayerGUI(String userName, Singleplayer sp) {
this.userName = userName;
setResizable(false);
setTitle("Console Clash Singleplayer");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(880, 550);
setLocationRelativeTo(null);
System.setIn(inPipe);

So far I've figured out that the problem most likey occurs when adding the outPipe to the console. Would I be able to fix this or am I just not able to use outPipes with this application?
Thanks in advance for your help.
The setVisible() method is invoked twice.. Remove the second setVisible() call after the Singleplayer.startOfGame(); line in SingleplayerGUI constructor.

Extending JTable and displaying in a JFrame

My code is still heavily in progress but my problem is that my class that extends JTable will not display in a JFrame. Here is my class that extends JTable. Secondly, I would like to know if the design option of making my LotteryTable an entirely new class a good idea.
At first, my LotteryDisplay contained a JTable which then was adjusted through a method tableSetup() which is now in LotteryTable.
public class LotteryTable extends JTable
{
private final String[] columnNames = {"Powerball Combos", "Odds of Winning", "Payout", "Number of Wins", "Win Frequency"};
JTable table;
public LotteryTable()
{
DefaultTableModel model = new DefaultTableModel(columnNames, 9);
table = new JTable(model)
{
public Class getColumnClass(int column)
{
if(column == 0)
return ImageIcon.class;
else
return String.class;
}
};
tableSetup();
setVisible(true);
}
public void tableSetup()
{
DefaultTableCellRenderer dtcr = new DefaultTableCellRenderer();
dtcr.setHorizontalAlignment(DefaultTableCellRenderer.CENTER);
table.setDefaultRenderer(String.class, dtcr);
ImageIcon p = new ImageIcon("Icons/Powerball.png"); //Not important to my problem
ImageIcon w1p = new ImageIcon("Icons/WhiteplusPowerball.png");
ImageIcon w2P = new ImageIcon("Icons/2WhitePlusPowerball.png");
ImageIcon w3P = new ImageIcon("Icons/3WhitePlusPowerball.png");
ImageIcon w4P = new ImageIcon("Icons/4WhitePlusPowerball.png");
ImageIcon w5P = new ImageIcon("Icons/5WhitePlusPowerball.png");
ImageIcon w3 = new ImageIcon("Icons/3White.png");
ImageIcon w4 = new ImageIcon("Icons/4White.png");
ImageIcon w5 = new ImageIcon("Icons/5White.png");
table.setValueAt(p, 0, 0);
table.setValueAt(w1p, 1, 0);
table.setValueAt(w2P, 2, 0);
table.setValueAt(w3, 3, 0);
table.setValueAt(w3P, 4, 0);
table.setValueAt(w4, 5, 0);
table.setValueAt(w4P, 6, 0);
table.setValueAt(w5, 7, 0);
table.setValueAt(w5P, 8, 0);
table.setValueAt("1 in 55", 0, 1);
table.setValueAt("1 in 111", 1, 1);
table.setValueAt("1 in 706", 2, 1);
table.setValueAt("1 in 360", 3, 1);
table.setValueAt("1 in 12,245", 4, 1);
table.setValueAt("1 in 19,088", 5, 1);
table.setValueAt("1 in 648,976", 6,1);
table.setValueAt("1 in 5,153,633", 7, 1);
table.setValueAt("1 in 175,223,510", 8, 1);
for(int i = 0; i < 10; i++)
{
table.setRowHeight(i, table.getRowHeight(i) + 10);
}
for(int i = 0; i < columnNames.length; i++)
{
TableColumn column = table.getColumnModel().getColumn(i);
column.setPreferredWidth(column.getPreferredWidth() + 80);
}
}
Here is the main class with the JPanel that is attempting to display my LotteryTable.
public class LotteryDisplay
{
private JFrame display;
private JPanel panel;
private LotteryTable table;
private static JCheckBox powerPlay;
public LotteryDisplay()
{
display = new JFrame("Powerball");
panel = new JPanel();
table = new LotteryTable();
powerPlay = new JCheckBox("Power Play");
panel.setPreferredSize(new Dimension(800, 300));
panel.add(powerPlay);
//JTableHeader header = table.getTableHeader(); //Not important to problem
//panel.add(header);
panel.add(table);
display.getContentPane().add(panel, BorderLayout.CENTER);
display.pack();
display.setVisible(true);
}
LotteryTable extends JTable, but then creates another JTable internally to itself which is never added to the any component capable of displaying it.
As to your second question...this arguable. I see no particular benefit in extending a JTable for the functionality you are adding. This could just as easily be achieved using a static configuration method which is passed a JTable
Working Example
import java.awt.BorderLayout;
import java.awt.EventQueue;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.table.DefaultTableModel;
public class LotteryTable {
public static void main(String[] args) {
new LotteryTable();
}
public LotteryTable() {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JTable table = new JTable();
configureLotteryTable(table);
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new JScrollPane(table));
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public static final String[] COLUMN_NAMES = {"Powerball Combos", "Odds of Winning", "Payout", "Number of Wins", "Win Frequency"};
public static void configureLotteryTable(JTable table) {
DefaultTableModel model = new DefaultTableModel(COLUMN_NAMES, 0) {
#Override
public Class<?> getColumnClass(int columnIndex) {
Class clazz = String.class;
switch (columnIndex) {
case 0:
clazz = ImageIcon.class;
break;
default:
clazz = String.class;
break;
}
return clazz;
}
};
table.setModel(model);
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 55"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 111"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 706"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 360"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 12,245"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 19,088"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 648,976"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 5,153,633"});
model.addRow(new Object[]{new ImageIcon(LotteryTable.class.getResource("/icons/Powerball.png")), "1 in 175,223,510"});
}
}
I would spend some more time reading through How to use Tables to freshen up on some of the concepts ;)
Whatever you're trying to do with the inner
JTable, you should be doing on the parent LotteryTable.
For illustration purposes, I replaced the reference to table with this:
public class LotteryTable extends JTable {
private static final String[] COLUMN_NAMES = {
"Powerball Combos",
"Odds of Winning",
"Payout",
"Number of Wins",
"Win Frequency" };
public LotteryTable() {
super(new DefaultTableModel(COLUMN_NAMES, 9));
tableSetup();
setVisible(true);
}
#Override
public Class<?> getColumnClass(int column) {
if (column == 0)
return ImageIcon.class;
else
return String.class;
}
private void tableSetup() {
DefaultTableCellRenderer dtcr = new DefaultTableCellRenderer();
dtcr.setHorizontalAlignment(DefaultTableCellRenderer.CENTER);
this.setDefaultRenderer(String.class, dtcr);
ImageIcon p = new ImageIcon("Icons/Powerball.png");
ImageIcon w1p = new ImageIcon("Icons/WhiteplusPowerball.png");
ImageIcon w2P = new ImageIcon("Icons/2WhitePlusPowerball.png");
ImageIcon w3P = new ImageIcon("Icons/3WhitePlusPowerball.png");
ImageIcon w4P = new ImageIcon("Icons/4WhitePlusPowerball.png");
ImageIcon w5P = new ImageIcon("Icons/5WhitePlusPowerball.png");
ImageIcon w3 = new ImageIcon("Icons/3White.png");
ImageIcon w4 = new ImageIcon("Icons/4White.png");
ImageIcon w5 = new ImageIcon("Icons/5White.png");
this.setValueAt(p, 0, 0);
this.setValueAt(w1p, 1, 0);
this.setValueAt(w2P, 2, 0);
this.setValueAt(w3, 3, 0);
this.setValueAt(w3P, 4, 0);
this.setValueAt(w4, 5, 0);
this.setValueAt(w4P, 6, 0);
this.setValueAt(w5, 7, 0);
this.setValueAt(w5P, 8, 0);
this.setValueAt("1 in 55", 0, 1);
this.setValueAt("1 in 111", 1, 1);
this.setValueAt("1 in 706", 2, 1);
this.setValueAt("1 in 360", 3, 1);
this.setValueAt("1 in 12,245", 4, 1);
this.setValueAt("1 in 19,088", 5, 1);
this.setValueAt("1 in 648,976", 6, 1);
this.setValueAt("1 in 5,153,633", 7, 1);
this.setValueAt("1 in 175,223,510", 8, 1);
for (int i = 0; i < 10; i++) {
this.setRowHeight(i, this.getRowHeight(i) + 10);
}
for (int i = 0; i < COLUMN_NAMES.length; i++) {
TableColumn column = this.getColumnModel().getColumn(i);
column.setPreferredWidth(column.getPreferredWidth() + 80);
}
}
}
I'd rather use a JFrame or JDialogand place a JPanel to display your JTable.
