JTable in a JDialog doesn't appear

I wanted to set a JTable of ArrayList content in a new JDialog. I debugged the code and the table model has its columns and rows set up, but JDialog doesn't show anything. I checked the similar questions and they all point that setVisible(true) should be being at the end. In my case, it already is. How can I show the JTable in that JDialog (including the data which comes from the ArrayList - that part should already be working), basically it's currently empty, there is no table at all.

String[] col = new String[] { "Инв. номер", "Заглавие", "Режисьор", "Жанр", "Година на излизане" };
DefaultTableModel tableModel = new DefaultTableModel(col, 0);
for (int i = 0; i < movies.size(); i++) {
String id = movies.get(i).getId();
String title = movies.get(i).getTitle();

}
//TableModel tableModel = new DefaultTableModel(movies.toArray(new Object[][] {}), columns.toArray());
table1 = new JTable(tableModel);
window.add(table1);
setVisible(true);
}
}

Here are a few things that I would change in your code. (Only considering the part regarding your dialog)
window.setLayout(null); // (1)
Don't use null layout. Learn to use appropriate Layout Managers, as swing was designed to be used with in conjunction with these. In your case, you can simply keep the default layout used by the JDialog, as you only have the JTable displayed anyways.
window.add(table1); // (2)
JTables are best used in combination in a JScrollPane, as this will automatically display the table header without you having to worry about it. Also, consider the How to Use Tables section of the Oracle Swing tutorial for more information on JTable usage.
Also (3), Java Swing applications should be run on the Event Dispatch Thread (see Concurrency in Swing).
Container window = getContentPane();
In your case, there is no need to explicitly retrieve the content pane from the dialog. This is just unnecessary overhead which you should not worry about. Calling add() on the dialog is enough in this case to add the component without having to deal with the content pane.
I took the "Dialog" portion of your code, including a excerpt of your Movie class and created a small working example (while trying not to change too much of your original code):
import java.util.Arrays;
import java.util.List;
import javax.swing.JDialog;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
import javax.swing.table.DefaultTableModel;
public class Test {
public static void main(String[] args) {
SwingUtilities.invokeLater(() -> { // (3) - run on EDT
Test t = new Test();
List<Movie> movies = Arrays.asList(t.new Movie("Movie1", "Title1"), t.new Movie("Movie2", "Title2"));
MyDialog dialog = t.new MyDialog(movies);
});
}
public class MyDialog extends JDialog {
public MyDialog(List<Movie> movies) {
setTitle("Title");
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
String[] col = new String[] { "ID", "Title" };
DefaultTableModel tableModel = new DefaultTableModel(col, 0);
for (int i = 0; i < movies.size(); i++) {
String id = movies.get(i).getId();
String title = movies.get(i).getTitle();
Object[] data = { id, title };
tableModel.addRow(data);
}
JTable table = new JTable(tableModel);
add(new JScrollPane(table)); // (2) - use a JScrollPane to display the table
pack(); // pack the dialog, components are sized according to their preferred size
setVisible(true);
}
}
class Movie {
private String id;
private String title;
public Movie(String id, String title) {
this.id = id;
this.title = title;
}
public String getId() {
return id;
}
public String getTitle() {
return title;
}
}
}
Result:
Considering these changes, you should be able to update your code to correctly display the JTable in your JDialog.
Sidenote:
I also don't really see a need here to extends JDialog. In your case, it would probably suffice to use a normal JDialog and simply add the JTable to it.

How to count data in jtable and show on the bottom of my gui

I have such an api. It shows JTable with 3 columns. I want that when I insert price and quantity to the jtable result will be seen on the bottom of my jframe. For example I insert data like on the picture and then get the result (2*5)+(2*5)=20. My result will be 20. And this result will be seen on the bottom of the gui window.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
public class Demo extends JFrame implements ActionListener{
private static void createAndShowUI() {

}
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {

update your addRow method in class FuDisplayPanel to return the total like this and
public int addRow(String name, String price, String quantity) {
Object[] row = new Object[3];
row[0] = name;
row[1] = price;
row[2] = quantity;
model.addRow(row);
int total = 0;
for (int count = 0; count < model.getRowCount(); count++){
price = model.getValueAt(count, 1).toString();
quantity = model.getValueAt(count, 2).toString();
if(price != null && !price.trim().equals("") && quantity != null && !quantity.trim().equals("")) {
total += Integer.parseInt(price) * Integer.parseInt(quantity);
}
}
return total;
}
public class FuButtonPanel extends JPanel {
private JButton addInfoButton = new JButton("Add Information");
public JLabel total = new JLabel("Total : ");
public FuButtonPanel() {
add(addInfoButton);
add(total);
}
public void addInfoBtnAddActionListener(ActionListener listener) {
addInfoButton.addActionListener(listener);
}
public void setTotal(int total) {
this.total.setText("Total : " + total);
}
}
and do this at FuGui.class
int total = displayPanel.addRow(name, price, quantity);
buttonPanel.setTotal(total);

Access the underlying data in the table via the model (Swing fundamental):
TableModel model = table.getModel();
Add a listener to the table model to do the automatic updates:
TableModelListener listener = new TableModelListener(tableChanged(TableModelEvent e) {
// update code here
}};
table.getModel().addTableModelListener(listener);

Displaying the values of an Arraylist with a JTable

I created a class named EmployeeGUI that is able to create any amount of user Employee objects and add them to an arraylist. The problem i have is that i have a JTable at the bottom of my GUI that i want to display all the objects that i've created but in my case the GUI Creates a new Table Object each time it goes through a for loop with the details of an object but as the for loop goes on the new details overwrites the old details rather than being added to the bottom of a jtable. Can anyone help me debug my errors?
Here is my Code

only comment, longer
see number of table1.setModel(new DefaultTableModel( created in loop for(int i = 0; i <empArray.size(); i++)
new Object[][] {{empArray.get(i).getFName(), empArray.get(i).getLName(),empArray.get(i).getMobile()}}, is converted to DataVector, you lost, haven't access to this array
(if is there reason to hold two the same arrays in your program then) use array based on util.List in AbstractTableModel

the new details overwrites the old details rather than being added to the bottom of a jtable.
First add all the record in a List then set the model just once otherwise it will override the last one in loop.
sample code:
if (action.equals("Display Employee")) {
List<Object[]> list = new ArrayList<Object[]>();
for (int i = 0; i < empArray.size(); i++) {
list.add(new Object[] {
empArray.get(i).getFName(),
empArray.get(i).getLName(),
empArray.get(i).getMobile()
});
}
table1.setModel(new DefaultTableModel(list.toArray(new Object[][] {}),
new String[] {"First Name", "Surname", "Phone Number"}));
}

You can use the addRow() method of the DefaultTableModel, like this:
((DefaultTableModel)table1.getModel()).addRow(new Object[] {
empArray.get(i).getFName(),
empArray.get(i).getLName(),
empArray.get(i).getMobile()
});

Posting from JTextFields into array

Ok So i have made my array and added an action listener so that when the button named "Submit" is clicked all data from my JTextFields should be entered into an ArrayList although this is not happening, any help on why not would be appreciated. below is the Action Listener action Performed.
public class Main {
String HouseNumber, StreetName, Town, Postcode, Beds, Price, Type;
JTextField HouseNumber1, StreetName1, Town1, Postcode1, Beds1, Price1,
Type1;
JLabel HouseNumberLabel, StreetNameLabel, TownLabel, PostcodeLabel,
BedsLabel, PriceLabel, TypeLabel;
JButton Submit;
JPanel panel;
JFrame frame;
public static void main(String[] args) {
Main gui = new Main();
gui.go();
}
public void go() {
frame = new JFrame();
panel = new JPanel();
HouseNumberLabel = new JLabel("House Number");
HouseNumber1 = new JTextField("");
StreetNameLabel = new JLabel("Street name");
StreetName1 = new JTextField("");
TownLabel = new JLabel("Town");
Town1 = new JTextField("");
PostcodeLabel = new JLabel("Postcode");
Postcode1 = new JTextField("");
BedsLabel = new JLabel("Number of beds");
Beds1 = new JTextField("");
PriceLabel = new JLabel("Price (£)");
Price1 = new JTextField("");
TypeLabel = new JLabel("Building Type");
Type1 = new JTextField("");
Submit = new JButton("Submit");
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
frame.getContentPane().add(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 300);
frame.setVisible(true);
// Add contents to JFrame and JPanel
panel.add(HouseNumberLabel);
panel.add(HouseNumber1);
panel.add(StreetNameLabel);
panel.add(StreetName1);
panel.add(TownLabel);
panel.add(Town1);
panel.add(PostcodeLabel);
panel.add(Postcode1);
panel.add(BedsLabel);
panel.add(Beds1);
panel.add(PriceLabel);
panel.add(Price1);
panel.add(TypeLabel);
panel.add(Type1);
panel.add(Submit);
frame.pack();
frame.show();
final ArrayList<Main> p = new ArrayList<Main>();
Submit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Main array = new Main();
HouseNumber = HouseNumber1.getText();
StreetName = StreetName1.getText();
Town = Town1.getText();
Postcode = Postcode1.getText();
p.add(array);
}
});
}
}

Although your Main class has the fields, since it's also managing the GUI, you don't want to create an ArrayList<Main>
If you just need to collect all the strings then you can create
ArrayList<String> houseDetails = new ArrayList<String>();
houseDetails.add(HouseNumber);
houseDetails.add(StreenName);
houseDetails.add(Town);
houseDetails.add(Postcode);
but the cleaner thing to do would be to create a class to manage these
class House
{
private String houseNumber;
private String streetName;
private String town;
private String postcode;
public String getHouseNumber() {
return houseNumber;
}
public void setHouseNumber(String houseNumber) {
this.houseNumber = houseNumber;
}
public String getStreetName() {
return streetName;
}
public void setStreetName(String streetName) {
this.streetName = streetName;
}
public String getTown() {
return town;
}
public void setTown(String town) {
this.town = town;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
}
and then create a House and set all the valuse.
final ArrayList<House> houses = new ArrayList<House>();
and in your actionPerformed event
House house = new House();
house.setHouseNumber(HouseNumber);
...
houses.add(house);

How do i add values entered into TextFields in a JPanel to an array?

I would like to add the values of "HouseNumber,StreetName,Town,Postcode" which are the textfields on my JPanel to the "Address" Array, What would be the best way to go about this? Thanks

I really don't understand the problem. You have all the methods that you need.
I'll try to give you some tips anyway.
First of all, if the JTextField are used to create new address, and not updating one of the existing, then a static array may not be the right choice. You should use ArrayList instead:
ArrayList<Address> p = new ArrayList<Address>();
Then simply retrieve the data from the JTextFields and construct another Address object:
Address newAddress = new Address(HouseNumber.getText(),
StreetName.getText(),
Town.getText(),
Postcode.getText());
p.add(newAddress);
Is this enough to solve your doubts ?
