When I initially run my Java Swing application, the padding and margining of the JLabel and JTextField components in a JPanel look good. But whenever I resize the application, the padding and margining for the labels and text fields increases so much that it does not look as good.
I understand a GridLayout has a set amount of vertical and horizontal spacing, but what can I do to make the spacing look better as the size of the application increases? I would also like the text in the text fields to resize as the text field increases but have been unable to figure it out.
I have been thinking to use a GridBagLayout but have not had much luck with that either. There is just way too much spacing as the size increases, which does not look good, and I have been unable to find or learn a good solution.
I would appreciate any advice.
Code:
package TestPackage;
import java.awt.GridLayout;
import javax.swing.*;
public class TestGridLayout {
public static void main(String[] args) {
JPanel testPanel = new JPanel();
GridLayout layoutManager = new GridLayout(5,2);
testPanel.setLayout(layoutManager);
JLabel platformEnumerationNameLabel = new JLabel();
JLabel logicalEnumerationNameFieldLabel = new JLabel();
JLabel valueTypeUnitNameFieldLabel = new JLabel();
JLabel measurementNameFieldLabel = new JLabel();
JLabel measurementAxisNameFieldLabel = new JLabel();
JTextField platformEnumerationNameField = new JTextField();
JTextField logicalEnumerationNameField = new JTextField();
JTextField valueTypeUnitNameField = new JTextField();
JTextField measurementNameField = new JTextField();
JTextField measurementAxisNameField = new JTextField();
platformEnumerationNameLabel.setText("Label 1");
testPanel.add(platformEnumerationNameLabel);
platformEnumerationNameField.setText("input some data");
testPanel.add(platformEnumerationNameField);
logicalEnumerationNameFieldLabel.setText("Label 2");
testPanel.add(logicalEnumerationNameFieldLabel);
logicalEnumerationNameField.setText("input some data");
testPanel.add(logicalEnumerationNameField);
valueTypeUnitNameFieldLabel.setText("Label 3");
testPanel.add(valueTypeUnitNameFieldLabel);
valueTypeUnitNameField.setText("input some data");
testPanel.add(valueTypeUnitNameField);
measurementNameFieldLabel.setText("Label 4");
testPanel.add(measurementNameFieldLabel);
measurementNameField.setText("input some data");
testPanel.add(measurementNameField);
measurementAxisNameFieldLabel.setText("Label 5");
testPanel.add(measurementAxisNameFieldLabel);
measurementAxisNameField.setText("input some data");
testPanel.add(measurementAxisNameField);
JDialog dialog = new JDialog();
dialog.add(testPanel);
dialog.setSize(700,200);
dialog.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
dialog.setVisible(true);
}
}
Use a different layout manager that doesn't resize all the components (unless you want them to)

Use a different layout manager (other then default FlowLayout which JPanel uses)

Also, avoid using setPreferredSize, let the layout managers do their job. In the example I'm used insets (from GridBagConstraints) and an EmptyBorder to add some additional space around the components
Also, be careful of using AWT components (ie Choice), they don't always play nicely with Swing. In this case, you should be using JComboBox

I tried adding BoxLayout because all the text fields and labels are on one line. So I tried box Layout and failed.
Can anyone show me how to make it like the title one line, label Different line, button different line?
Like this:
As camickr says in his comment, you generally use a GridBagLayout to create a form.
I reworked your code because I hope to show a better way to code a GUI panel.
Here's the GUI.
The major changes I made include:
All Swing applications must start with a call to the SwingUtilities invokeLater method. This method ensures that all Swing components are created and executed on the Event Dispatch Thread.
I organized the GUI code into three methods so I could focus on one part of the GUI at a time. The JFrame is created in the run method. The title JPanel is created in the createTitlePanel method. The form JPanel is created in the createFormPanel method. The code for the JFrame will rarely change from Swing application to Swing application.
I use Swing components. I don't extend Swing components, or any Java class, unless I intend to override one of the class methods.
The createFormPanel class uses the GridBagLayout to organize the labels and text fields in columns. You can think of the GridBagLayout as a flexible grid. The cells of the grid don't have to be the same size. The Oracle tutorial, How to Use GridBagLayout, has another example.
I put the ActionListener in a separate class. I made it an inner class in this example so I could paste the code as one file. Generally, you should put separate classes in separate files. It makes each class shorter and easier to understand.
Here's the runnable, example code.

Edited to add: If you want the title JLabel to be right-justified, you'll have to switch to a BorderLayout. I added an empty border so the text wouldn't be on the right edge of the JFrame.
Here's the changed method.
private JPanel createTitlePanel(String title) {
JPanel panel = new JPanel(new BorderLayout());
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 0, 10));
JLabel lblTitle = new JLabel(title);
lblTitle.setFont(new Font("Forte", Font.PLAIN, 40));
lblTitle.setForeground(Color.BLUE);
panel.add(lblTitle, BorderLayout.AFTER_LINE_ENDS);
return panel;
}

Am i using the wrong layout or my coding are having problems?
Well, yes, a little, but it has more to do with the size of your JFrame, never call setSize() on them, instead call pack(). However if you change it for pack(), the default orientation of the FlowLayout is FlowLayout.HORIZONTAL and thus all your components will go to the right of each other.
Then, you have 2 options:
Keep the JFrame's layout as FlowLayout but make two JPanels, one for the image and one for the data, the image might have the default FlowLayout as well but the other one might have GridLayout.
Use GridBagLayout for all your components, letting the image JLabel to have a height of 7 cells and all the others a height of 1.
For the following example I will be using the GridBagLayout option, and I recommend you to try to make the multipanel option (option 1).
However, before starting I must mention your other problems in your code:
You're not following the Java naming conventions: firstWordLowerCaseVariable, firstWordLowerCaseMethods(), FirstWordUpperCaseClasses, ALL_WORDS_UPPER_CASE_CONSTANTS, this will make your code easier to read and understand for you and for us.
You're not changing the behavior of the JFrame so, there's no need to inherit from it: See Extends JFrame vs. creating it inside the program for more information.
Related to the above point, it's wise to build your GUI towards JPanels instead of JFrames, see: The Use of Multiple JFrames: Good or Bad Practice? as well, as I think you might end up in similar problems in the future.
You're not placing your program on the Event Dispatch Thread (EDT), see this related answer to see how to solve this problem.
You're calling setSize(...) method, and as I said before, it's always better to call pack() method instead, leaving the calculations for the GUI size to the layout manager.
You're calling setVisible before adding all your components to the GUI, this could lead you to blank or black screens, it should be the last line in your program.
Related to the above point, I always like to start doing the GUI from inside out and adding the items that way, instead of outside in.
Why are you using JTextAreas instead of JTextFields for the user information?
Now, the code that follows the above recommendations using the 2nd option I gave you is this:

pane.add(pokestopVisitedButton, gbc);
frame.add(pane);
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
And it produces a GUI similar to this one:
I am trying to create a simple email client and the bottom of the body is being cut-off. If I add a horizontal scroll bar, it does not appear, and the bottom of the Vertical scroll bar does not appear either.
Here is my code:

In my main class I am just creating a new gui and then calling the addElements() function.
FlowLayout doesn't "wrap" well. Consider a different layout, GridBagLayout for example...
Also, stop "trying" to force a size onto your UI, you don't have enough control over the factors which affect sizing to do this.
Instead, rely on the layout managers and API functionality. For example, instead of calling setSize on your frame, call pack...I would have posted soon, but it took me this long to find that call...I was scratching my head wondering why the UI wouldn't layout the way I expected...

The problem is because of FlowLayout Manager is being used. I have solved your problem with a different layout manager.
Before posting the solution here are some tips that you should follow
Change your class name. It should be in camel-case
Try to call pack() instead of setSize() as it will handle it automatically. When I replaced your setSize() with pack(), it was showing a awkward looking GUI which proves your layout and adding elements were not proper.
Font size30 = new Font(null, Font.PLAIN, 30);
JPanel pnl = new JPanel();
pnl.setLayout(new BoxLayout(pnl,BoxLayout.Y_AXIS));
Container contentPane = getContentPane();
//--- User Info ---//
JPanel userInfo = new JPanel();
JLabel userLabel = new JLabel("Username: ");
JTextField userField = new JTextField(12);
userInfo.add(userLabel);
userInfo.add(userField);
JLabel passLabel = new JLabel("Password: ");
JTextField passField = new JTextField(10);
userInfo.add(passLabel);
userInfo.add(passField);
JLabel serverLabel = new JLabel("Mail Server: ");
JTextField serverField = new JTextField(10);
userInfo.add(serverLabel);
userInfo.add(serverField);
JLabel portLabel = new JLabel("Server Port: ");
JTextField portField = new JTextField(3);
userInfo.add(portLabel);
userInfo.add(portField);
//--- To: CC: and Subject Fields ---//
JPanel msgInfo = new JPanel();
JLabel toLabel = new JLabel("To: ");
JTextField toField = new JTextField(30);
msgInfo.add(toLabel);
msgInfo.add(toField);
JLabel subLabel = new JLabel("Subject: ");
JTextField subField = new JTextField(30);
msgInfo.add(subLabel);
msgInfo.add(subField);
//--- Body ---//
JLabel bodyLabel = new JLabel("Body");
bodyLabel.setFont(size30);
JTextArea bodyField = new JTextArea(30,70);
bodyField.setLineWrap(true);
bodyField.setWrapStyleWord(true);
JScrollPane bodyScroll = new JScrollPane(bodyField);
bodyScroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
bodyScroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
pnl.add(userInfo);
pnl.add(msgInfo);
pnl.add(bodyLabel);
pnl.add(bodyScroll);
contentPane.add(pnl);
setVisible(true);
pack();
This is what i want to achieve
I used grid layout and this is what have
and my code goes (not full code can provide one if needed).
components.setLayout(new GridLayout(4,0));
components.setBorder(BorderFactory.createTitledBorder("Personal Data"));
//Lable to display
name.setText("Resident Name");
roomNo.setText("Room Number");
age.setText("Age");
gender.setText("Gender");
careLvl.setText("Care Level");
components.add(name);
components.add(textFieldForName);
components.add(roomNo);
components.add(textFieldForAge);
components.add(age);
components.add(coForAge);
components.add(gender);
components.add(coForGender);
components.add(careLvl);
components.add(coForCareLvl);
any heads up would be greatly appreciated.
GridLayout does just that, it layouts components out in a grid, where each cell is percentage of the available space based on the requirements (ie width / columns and height / rows).
Take a look at A Visual Guide to Layout Managers for examples of the basic layout managers and what they do.
I would recommend that you take a look at GridBagLayout instead. It is the most flexible (and most complex) layout manager available in the default libraries.
For Example
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestLayout31 {
public static void main(String[] args) {
new TestLayout31();
}
public TestLayout31() {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
public TestPane() {
JLabel lblRes = new JLabel("Resident Name");
JLabel lblRoomNo = new JLabel("RoomNo");
JLabel lblAge = new JLabel("Age");
JLabel lblGender = new JLabel("Gender");
JLabel lblCare = new JLabel("Care level");
JTextField fldRes = new JTextField("john smith", 20);
JTextField fldRoomNo = new JTextField(10);
JComboBox cmbAge = new JComboBox(new Object[]{51});
JComboBox cmbGener = new JComboBox(new Object[]{"M", "F"});
JComboBox cmbCare = new JComboBox(new Object[]{"Low"});
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(1, 1, 1, 1);
add(lblRes, gbc);
gbc.gridx++;
gbc.gridwidth = 4;
gbc.fill = GridBagConstraints.HORIZONTAL;
add(fldRes, gbc);
gbc.gridx = 7;
gbc.gridwidth = 1;
gbc.fill = GridBagConstraints.NONE;
add(lblRoomNo, gbc);
gbc.gridx++;
add(fldRoomNo, gbc);
gbc.gridy++;
gbc.gridx = 1;
add(lblAge, gbc);
gbc.gridx++;
add(cmbAge, gbc);
gbc.gridx++;
add(lblGender, gbc);
gbc.gridx++;
add(cmbGener, gbc);
gbc.gridx++;
gbc.gridwidth = 2;
add(lblCare, gbc);
gbc.gridx += 2;
gbc.gridwidth = GridBagConstraints.REMAINDER;
add(cmbCare, gbc);
}
}
}
Compound Layout Example
Another option would be to use a compound layout. This is, you separate each section of your UI into separate containers, concentrating on their individual layout requirements.
For example, you have two rows of fields, each which don't really relate to each other, so rather than trying to figure out how to make the fields line up, you can focus on each row separately...
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestLayout31 {
public static void main(String[] args) {
new TestLayout31();
}
public TestLayout31() {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
public TestPane() {
JPanel topPane = new JPanel(new GridBagLayout());
JLabel lblRes = new JLabel("Resident Name");
JLabel lblRoomNo = new JLabel("RoomNo");
JLabel lblAge = new JLabel("Age");
JLabel lblGender = new JLabel("Gender");
JLabel lblCare = new JLabel("Care level");
JTextField fldRes = new JTextField("john smith", 20);
JTextField fldRoomNo = new JTextField(10);
JComboBox cmbAge = new JComboBox(new Object[]{51});
JComboBox cmbGener = new JComboBox(new Object[]{"M", "F"});
JComboBox cmbCare = new JComboBox(new Object[]{"Low"});
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(1, 1, 1, 1);
topPane.add(lblRes, gbc);
gbc.gridx++;
gbc.fill = GridBagConstraints.HORIZONTAL;
topPane.add(fldRes, gbc);
gbc.gridx++;
topPane.add(lblRoomNo, gbc);
gbc.gridx++;
topPane.add(fldRoomNo, gbc);
JPanel bottomPane = new JPanel(new GridBagLayout());
gbc.gridx = 0;
bottomPane.add(lblAge, gbc);
gbc.gridx++;
bottomPane.add(cmbAge, gbc);
gbc.gridx++;
bottomPane.add(lblGender, gbc);
gbc.gridx++;
bottomPane.add(cmbGener, gbc);
gbc.gridx++;
bottomPane.add(lblCare, gbc);
gbc.gridx++;
bottomPane.add(cmbCare, gbc);
gbc.gridx = 0;
gbc.gridy = 0;
gbc.weightx = 1;
gbc.fill = GridBagConstraints.HORIZONTAL;
add(topPane, gbc);
gbc.gridy++;
add(bottomPane, gbc);
}
}
}
This will make it easier to modify the UI later should you have to...

JPanel contentPane = new JPanel();
JPanel northPane = new JPanel();
JPanel centerPane = new JPanel();
JPanel southPane = new JPanel();
contentPane.setLayout(new BorderLayout());
northPane.setLayout( new GridLayout(1, 6));
southPane.setLayout( new GridLayout(1, 7));
contentPane.add(northPane, BorderLayout.NORTH );
contentPane.add(centerPane, BorderLayout.CENTER);
contentPane.add(southPane, BorderLayout.SOUTH );
frame.setContentPane(contentPane);
