I am trying to create a series of panels in JTabbedPane that displays a segment of info for the user. Right now, I am trying to get it so that the panel will refresh after the edit button is clicked. This button brings you to a different menu where you can adjust any of the fields and then go back to the tabbed pane. Unfortunately, while the object is changing by using the aforementioned menu, the pane does not reflect those changes correctly. What is does is make the first panel and all the tabs unclickable and seems to add a new panel to the bottom of the previous one with the new information. This occurs during the repaint() as previously it would not change at all.
JPanel leftPanel = new JPanel();
JPanel buttons = new JPanel();
JPanel title = new JPanel();
LayoutManager singleLine = new GridLayout(0,2);
leftPanel.setLayout(singleLine);
buttons.setLayout(new FlowLayout());
JLabel header = new JLabel("Basic Student Information");
title.add(header);
JLabel StreetLabel = new JLabel("First Name: "); //Creates all Labels
JLabel LNLabel = new JLabel("Last Name: ");
JLabel IDLabel = new JLabel("Student ID: ");
JLabel GPALabel =new JLabel("GPA: ");
JLabel StreetInfo = new JLabel(selectedStudent.getFirstName().toString());
JLabel LNInfo = new JLabel(selectedStudent.getLastName().toString());
JLabel IDInfo = new JLabel(selectedStudent.getID().toString());
JLabel GPAInfo = new JLabel(selectedStudent.getGpa().toString());
leftPanel.add(StreetLabel);
leftPanel.add(StreetInfo);
leftPanel.add(LNLabel);
leftPanel.add(LNInfo);
leftPanel.add(IDLabel);
leftPanel.add(IDInfo);
leftPanel.add(GPALabel);
leftPanel.add(GPAInfo);
StreetLabel.setHorizontalAlignment(JLabel.LEFT);
LNLabel.setHorizontalAlignment(JLabel.LEFT);
IDLabel.setHorizontalAlignment(JLabel.LEFT);
GPALabel.setHorizontalAlignment(JLabel.LEFT);
JButton edit = new JButton("Edit");
JButton close = new JButton("Close");
buttons.add(edit);
buttons.add(close);
basicInfoTab.add(title, BorderLayout.NORTH);
basicInfoTab.add(leftPanel, BorderLayout.CENTER);
basicInfoTab.add(buttons, BorderLayout.SOUTH);
edit.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent event){
readMenu.setVisible(false);
generalInfo();
}
});
close.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent event){
if(JOptionPane.showConfirmDialog(null, "Do you wish to exit this student's record?") == JOptionPane.OK_OPTION){
readMenu.setVisible(false);
HomeScreen();
}
}
});
Any help in getting this to refresh successfully would be very much appreciated.

As stated in the title i need to move the label for the text box to be above the box and not to the side. attached i have a picutres of what i mean. what i have vs what i want i have tried searching for it but i cannot seem to find the answer im looking for/not exactly sure what to look up. I have tried using JFrame but it made a separate window unless i need to make the entire GUI a JFrame for me to get the result i want?
Also the actionPerformed method has things but it is irrelevant to the question but displays correctly still.

You can use a nested JPanel with another layout in order to achieve that. I would go with BorderLayout here. You can also other layouts that allow vertical orientation. Visiting the visual guide to Layout Managers will help you spot them.
JLabel name_label = new JLabel("Name on Order");
name.addActionListener(this);
JPanel verticalNestedPanel = new JPanel(new BorderLayout());
verticalNestedPanel.add(name_label, BorderLayout.PAGE_START);
verticalNestedPanel.add(name, BorderLayout.PAGE_END);
panel5.add(verticalNestedPanel);
How can I make my CheckBox allign in Left side and what should I use layout to make it every checkbox print in another line?

Please Help me
Please help me I am new to this kind of codes.
i want save input that i get from user and save them in element .
i want to access elements that user write in my UI.
and if i want save the elements in array list which kind of array list i should build.
in my UI i have text field name and text field middle name and combo box city has got 3 city name and and a radio box that it depend sex.
in final show them in console what should i do ?
this all of my code:
package ui;
import java.awt.*;
import javax.swing.*;
public class UI extends JFrame
{
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setVisible(true);
frame.setSize(500, 600);
BorderLayout blayout = new BorderLayout();
JButton center = new JButton();
JButton north = new JButton();
JButton south = new JButton();
JComboBox combo = new JComboBox();
combo.addItem("-");
combo.addItem("Tehran");
combo.addItem("Tabriz");
combo.addItem("Shiraz");
JRadioButton rb1 = new JRadioButton("man");
JRadioButton rb2 = new JRadioButton("weman");
frame.setLayout(blayout);
FlowLayout fLoyout = new FlowLayout(FlowLayout.CENTER);
center.setLayout(fLoyout);
south.setLayout(fLoyout);
JLabel jb1 = new JLabel("Name :");
JTextField name = new JTextField(20);
center.add(jb1);
center.add(name);
JLabel jb2 = new JLabel("Family :");
JTextField family = new JTextField(20);
center.add(jb2);
center.add(family);

cpanel.add(jb6);
cpanel.add(comment);
frame.add(cpanel,BorderLayout.CENTER);
frame.add(spanel,BorderLayout.SOUTH);
}
}
You need to use listeners to create code that runs when ui component is pressed. I added listener to every component. try it:
public class UI extends JFrame {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setSize(500, 600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
BorderLayout blayout = new BorderLayout();
JButton center = new JButton();
JButton north = new JButton();
JButton south = new JButton();
south.addActionListener(e->{System.out.println("Save button is pressed");});
JComboBox combo = new JComboBox();
combo.addItem("-");
combo.addItem("Tehran");
combo.addItem("Tabriz");
combo.addItem("Shiraz");
combo.addActionListener(e -> {
System.out.println(((JComboBox<String>) e.getSource()).getSelectedItem());
});
JRadioButton rb1 = new JRadioButton("man");
rb1.addActionListener(e -> {
System.out.println("man: " + ((JRadioButton) e.getSource()).isSelected());
});
JRadioButton rb2 = new JRadioButton("weman");
rb2.addActionListener(e -> {
System.out.println("weman: " + ((JRadioButton) e.getSource()).isSelected());
});
frame.setLayout(blayout);
FlowLayout fLoyout = new FlowLayout(FlowLayout.CENTER);
center.setLayout(fLoyout);
south.setLayout(fLoyout);
JLabel jb1 = new JLabel("Name :");
JTextField name = new JTextField(20);
center.add(jb1);
center.add(name);
name.addActionListener(e -> {
System.out.println("name: " + ((JTextField) e.getSource()).getText());
});
JLabel jb2 = new JLabel("Family :");
JTextField family = new JTextField(20);
center.add(jb2);
center.add(family);
family.addActionListener(e -> {
System.out.println("family: " + ((JTextField) e.getSource()).getText());
});
JLabel jb4 = new JLabel("City :");
center.add(jb4);
center.add(combo);
JLabel jb5 = new JLabel("Sex :");
center.add(jb5);
center.add(rb1);
center.add(rb2);
JLabel jb6 = new JLabel("Comment :");
JTextField comment = new JTextField(50);
comment.addActionListener(e -> {
System.out.println("comment: " + ((JTextField) e.getSource()).getText());
});
JLabel jb7 = new JLabel("Save");
south.add(jb7);
JPanel cpanel = new JPanel();
cpanel.add(center);
JPanel spanel = new JPanel();
spanel.add(south);
cpanel.setLayout(new BoxLayout(cpanel, BoxLayout.Y_AXIS));
cpanel.add(jb6);
cpanel.add(comment);
frame.add(cpanel, BorderLayout.CENTER);
frame.add(spanel, BorderLayout.SOUTH);
frame.pack();
frame.setVisible(true);
}
}
You will have to put JRadioButton into RadioGroup to select one of them.
At first, you need to check your GUI, because from skimming it works not good. Later you can get data from the different component using an appropriate listener for each component or you can use any General button to reading data from all components and print it in a console or anywhere else.
To get data from combo, for example, will be here:
String data = combo.getSelectedIndex();

How can I get the user input in Java?
I tried to do this from stackoverflow:
adding multiple jPanels to jFrame
But that didn't seem to work out like in the example, could anyone tell me what im doing wrong?
Im trying to add multiple JPanels with each their own sizes to the JFrame. I was also hoping it was possible to give each JPanel specific sizes and ability to put them on the exact spot i want.
Picture of what i try to make:
This is my code so far:
public ReserveringenGUI(ReserveringController controller) {
this.controller = new ReserveringController();
makeFrame();
}
public void makeFrame() {
JFrame frame1 = new JFrame();
frame1.setTitle("Reserveringen");
frame1.setSize(800, 500);
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel container = new JPanel();
container.setLayout(new BoxLayout(container, BoxLayout.X_AXIS));
JPanel willekeurigPanel = new JPanel();
willekeurigPanel.setSize(400, 500);
willekeurigPanel.setBackground(Color.YELLOW);
willekeurigPanel.setVisible(true);
JPanel overzichtPanel = new JPanel();
overzichtPanel.setSize(400, 500);
overzichtPanel.setBackground(Color.red);
overzichtPanel.setVisible(true);
DateFormat format = new SimpleDateFormat("dd-MM-yyyy");
DateFormatter df = new DateFormatter(format);
JFormattedTextField dateBeginField = new JFormattedTextField(df);
dateBeginField.setPreferredSize(new Dimension(250, 20));
dateBeginField.setValue(new Date());
JFormattedTextField dateEndField = new JFormattedTextField(df);
dateEndField.setPreferredSize(new Dimension(250, 20));
dateEndField.setValue(new Date());
JTextField klantnummer = new JTextField();
klantnummer.setPreferredSize(new Dimension(250, 20));
JTextField artikelnummer = new JTextField();
artikelnummer.setPreferredSize(new Dimension(250, 20));
JLabel dateBeginLabel = new JLabel("Begin Datum ");
JLabel dateEndLabel = new JLabel("Eind datum: ");
JLabel klantID = new JLabel("Klant nummer: ");
JLabel artikelID = new JLabel("Artikel nummer: ");
JButton voegReserveringToe = new JButton("Voeg toe");
voegReserveringToe.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
voegReserveringToeActionPerformed(evt);
}
});
willekeurigPanel.add(dateBeginLabel);
willekeurigPanel.add(dateBeginField);
willekeurigPanel.add(dateEndLabel);
willekeurigPanel.add(dateEndField);
willekeurigPanel.add(klantID);
willekeurigPanel.add(klantnummer);
willekeurigPanel.add(artikelID);
willekeurigPanel.add(artikelnummer);
willekeurigPanel.add(voegReserveringToe);
container.add(willekeurigPanel);
container.add(overzichtPanel);
frame1.add(container);
frame1.setVisible(true);
}
As discussed here, don't set the size and position of components arbitrarily. Instead, let the layout do the work, nesting as required. Use the GroupLayout shown here for the labeled input fields. Add each to the CENTER of a panel having BorderLayout, with a button in the SOUTH on the left. Finally, add both panels to an enclosing panel having GridLayout(1, 0).
I'm trying to use a grid layout to make a GUI window. I add all my components and it compiles but when it runs it doesn't show anything. I'm trying to make a simple layout grouped and stacked like this.
{introduction message}
{time label
time input text}
{gravity label
gravity input text}
{answer label
answer text box}
{calculate button clear button}
Here is my code
import javax.swing.*;
import java.awt.*;
public class TurnerRandyFallingGUI extends JFrame
{
final int WINDOW_HEIGHT=500;
final int WINDOW_WIDTH=500;
public TurnerRandyFallingGUI()
{
setTitle("Falling Distance Calculator");
setSize(WINDOW_WIDTH,WINDOW_HEIGHT);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new GridLayout(1, 5));
//labels
JLabel introMessage = new JLabel("Welcome to the Falling distance"+
"calculator");
JLabel timeLabel = new JLabel("Please enter the amount of time "+
"in seconds the object was falling.");
JLabel gravityLabel = new JLabel("Enter the amount of gravity being "+
"forced onto the object");
JLabel answerLabel = new JLabel("Answer");
//text fields
JTextField fTime = new JTextField(10);
JTextField gForce = new JTextField(10);
JTextField answerT = new JTextField(10);
//buttons
JButton calculate = new JButton("Calculate");
JButton clr = new JButton("clear");
//panels
JPanel introP = new JPanel();
JPanel timeP = new JPanel();
JPanel gravityP = new JPanel();
JPanel answerP = new JPanel();
JPanel buttonsP = new JPanel();
//adding to the panels
//intro panel
introP.add(introMessage);
//time panel
timeP.add(timeLabel);
timeP.add(fTime);
//gravity panel
gravityP.add(gravityLabel);
gravityP.add(gForce);
//answer panel
answerP.add(answerLabel);
answerP.add(answerT);
//button panel
buttonsP.add(calculate);
buttonsP.add(clr);
setVisible(true);
}
public static void main(String[] args)
{

}
}
You've added nothing to the JFrame that your class above extends. You need to add your components to containers whose hierarchy eventually leads to the top level window, to the this if you will. In other words, you have no add(someComponent) or the functionally similar this.add(someComponent)method call in your code above.
Consider adding all of your JPanels to a single JPanel
Consider adding that JPanel to the JFrame instance that is your class by calling add(thatJPanel).
Even better would be to not extend JFrame and just to create one when needed, but that will likely be the subject of another discussion at another time.
Before setVisible (true) statement add following statements:
add (introP);
add (timeP);
add (gravityP);
add (answerP);
add (buttonsP);
There is nothing in your JFrame. That is the reason

setLayout(new GridLayout(5, 1));
this.add(introP);
this.add(timeP);
this.add(gravityP);
this.add(answerP);
this.add(buttonsP);
setTitle("Falling Distance Calculator");
this.pack();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
this.validate();
}
public static void main(String[] args)
{
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
new TurnerRandyFallingGUI();
}
});
}
}
Consider the following
In GridLayout, the first parameter is Rows, Second is columns
Never set the size of JFrame manually. Use pack() method to decide
the size
Use SwingUtilities.InvokeLater() to run the GUI in another thread.
