I want my JTabbedpane on top of panel3 and panel4. Rightnow, JTabbedpane is on top of panel1 and panel2 but I want it on top of panel3 and panel4. I try setBounds to bring JTabbedpane down but it doesn't work. Thanks for everyone help.

This is the picture I am trying to replicate
This is what I have (didn't add icon images yet)
I can't seem to find a solution, been staring at it for quite some time.
I am trying to replicate the following picture, using GridLayout for the buttons and the figure out the rest on my own using Java Swing. Furthermore, I've added my buttons into a JPanel and now I'm trying to add spacing between the panel and the pane.
This is what I have, how can I go about it?
super(title);
this.setLayout(new BoxLayout(this.getContentPane(), BoxLayout.PAGE_AXIS));
Container pane = this.getContentPane();
JButton b1 = new JButton();
b1.setBackground(Color.white);
JButton b2 = new JButton();
b2.setBackground(Color.white);
JButton b3 = new JButton();
b3.setBackground(Color.white);
JButton b4 = new JButton();
b4.setBackground(Color.white);
JButton b5 = new JButton();
b5.setBackground(Color.white);
JButton b6 = new JButton();
b6.setBackground(Color.white);
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(2,3,10,10));
panel.setBackground(Color.black);
panel.add(b1);
panel.add(b2);
panel.add(b3);
panel.add(b4);
panel.add(b5);
panel.add(b6);
pane.add(panel);
this.setSize(500,500);
this.setVisible(true);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
The easiest way to do it would be to add an empty border to your JPanel (see this post on empty borders):
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(3, 2, 10, 10));
// ...
panel.setBorder(new EmptyBorder(50, 50, 50, 50));
Another good approach (depending always on your application needs), if you have the JButton preferred size set, would be to have the main JPanel's grid layout set to have two columns and one row, with another JPanel inside each column. Adding to the interior JPanels a BoxLayout in Y_AXIS mode and aligning the buttons with setAlignmentX() would work great too (note this approach wouldn't center the JButtons vertically) (see How to use BoxLayout):
public class MyFrame extends JFrame {
private String title = "Title";
public MyFrame(){
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new GridLayout(1,2,10,10));
JPanel rightPanel = new JPanel();
rightPanel.setLayout(new BoxLayout(rightPanel, BoxLayout.Y_AXIS));
JPanel leftPanel = new JPanel();
leftPanel.setLayout(new BoxLayout(leftPanel, BoxLayout.Y_AXIS));
mainPanel.add(leftPanel);
mainPanel.add(rightPanel);
JButton b1 = new JButton();
b1.setBackground(Color.white);
//b1.setIcon(new ImageIcon(img1));
b1.setAlignmentX(Component.RIGHT_ALIGNMENT);
leftPanel.add(b1);
JButton b2 = new JButton();
b2.setBackground(Color.white);
//b2.setIcon(new ImageIcon(img2));
b2.setAlignmentX(Component.RIGHT_ALIGNMENT);
leftPanel.add(b2);
JButton b3 = new JButton();
b3.setBackground(Color.white);
//b3.setIcon(new ImageIcon(img3));
b3.setAlignmentX(Component.RIGHT_ALIGNMENT);
leftPanel.add(b3);
JButton b4 = new JButton();
b4.setBackground(Color.white);
//b4.setIcon(new ImageIcon(img4));
b4.setAlignmentX(Component.LEFT_ALIGNMENT);
rightPanel.add(b4);
JButton b5 = new JButton();
b5.setBackground(Color.white);
//b5.setIcon(new ImageIcon(img5));
b5.setAlignmentX(Component.LEFT_ALIGNMENT);
rightPanel.add(b5);
JButton b6 = new JButton();
b6.setBackground(Color.white);
//b6.setIcon(new ImageIcon(img6));
b6.setAlignmentX(Component.LEFT_ALIGNMENT);
rightPanel.add(b6);
add(mainPanel); //Adding our mainPanel to the contentPane of the JFrame
this.setSize(500,500); //or pack();
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setTitle(title);
this.setVisible(true);
}
}
Here's a little demonstration I whipped up.
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.
You don't set the size of the JFrame and try and make the Swing components fit. You let the JFrame pack with all the Swing components.
You create a GridLayout JPanel inside of a FlowLayout JPanel. The FlowLayout JPanel uses an empty border of the appropriate size.
I used the image the OP provided to get the icons.
Here's the complete runnable code.

I am new to programming and still learning. I need help in positioning a JLabel "Welcome back" on top of the GUI interface. The label keeps getting stuck in the middle despite my efforts. Feel free to correct any other mistakes shown in the code that I can do better.
public class MainMenu {
public static void main(String[] args) {
JFrame frame = new JFrame("Main Menu");
JPanel panel = new JPanel();
panel.setBounds(30, 80, 400, 570);
panel.setLayout(new GridLayout(3, 2, 15, 15));
panel.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT);
JButton meals = new JButton("Meals");
meals.setFont(new Font("Helvetica", Font.BOLD, 24));
meals.setOpaque(true);
JButton reminder = new JButton ("Reminders");
reminder.setFont(new Font("Helvetica", Font.BOLD, 24));
reminder.setOpaque(true);
JButton shop = new JButton ("Shop");
shop.setFont(new Font("Helvetica", Font.BOLD, 24));
shop.setOpaque(true);
JButton sleep = new JButton ("Sleep Timer");
sleep.setFont(new Font("Helvetica", Font.BOLD, 24));
sleep.setOpaque(true);
JButton account = new JButton ("My Account");
account.setFont(new Font("Helvetica", Font.BOLD, 24));
account.setOpaque(true);
JButton aboutus = new JButton ("About Us");
aboutus.setFont(new Font("Helvetica", Font.BOLD, 24));
aboutus.setOpaque(true);
JLabel label = new JLabel("Welcome back!");
label.setLocation(240, 20);
panel.add(meals);
panel.add(reminder);
panel.add(shop);
panel.add(sleep);
panel.add(account);
panel.add(aboutus);
frame.add(panel);
frame.add(label);
frame.setSize(480, 720);

Panels are rearranged on an intermediary Layout-manager(Border)
There are also various solutions based on Layout-used, but the main idea is the same

panel.setBounds(30, 80, 400, 570);
panel.setLayout(new GridLayout(3, 2, 15, 15));

JButton aboutus = new JButton ("About Us");
aboutus.setFont(new Font("Helvetica", Font.BOLD, 24));
aboutus.setOpaque(true);

Days ago i asked for help to put a JPanel on top of the other CardLayout panels, with the help of one of the users i achieved it using GlassPane, so thanks to him, but now i wanna close it whenever i click outside it(in other windows of the applications or components) because its stuck there until i click settings button, how can i achieve that? I have tried with focus lost and gained but that doesn't work with the panel so what am i supposed to do, here is my piece of code..

I've slightly modified my previous example, so the settings panel goes closed on the click outside it.

I'd like to have the JButton panel consume ~30% of the frames horizontal space.
And glCanvas on the right side taking up the rest of the frames space.
How can I achieve this layout?
Currently:
Main.java
GLProfile profile = GLProfile.get(GLProfile.GL2);
GLCapabilities capabilities = new GLCapabilities(profile);
GLCanvas glcanvas = new GLCanvas(capabilities);
glcanvas.addGLEventListener(new GameRenderer());
glcanvas.setSize(100, 100);
JFrame frame = new JFrame("Tool");
JPanel panel = new JPanel();
JPanel cpanel=new JPanel();
panel.setLayout(null);
cpanel.setLayout(null);
JButton ButtonBR = new JButton("1");
JButton ButtonE = new JButton("2");
JButton ButtonR = new JButton("3");
JButton ButtonC = new JButton("4");
JButton ButtonT = new JButton("5");
JButton ButtonCR = new JButton("6");
ButtonBR.setBounds(10, 30, 150, 40);
ButtonE.setBounds(10, 80, 150, 40);
ButtonR.setBounds(10, 130, 150, 40);
ButtonC.setBounds(10, 180, 150, 40);
ButtonT.setBounds(10, 230, 150, 40);
ButtonCR.setBounds(10, 450, 150, 40);
cpanel.add(glcanvas);
panel.add(ButtonBR);
panel.add(ButtonE);
panel.add(ButtonR);
panel.add(ButtonC);
panel.add(ButtonT);
panel.add(ButtonCR);
frame.add(cpanel);
frame.add(panel);
frame.setSize(Toolkit.getDefaultToolkit().getScreenSize().width, Toolkit.getDefaultToolkit().getScreenSize().height);
frame.setVisible(true);
Animator animator = new Animator(glcanvas));
animator.start();
Consider using a MigLayout as such:
import javax.swing.JFrame;
import javax.swing.JLabel;
import net.miginfocom.swing.MigLayout;
import javax.swing.JTextField;
public class Main extends JFrame {
private static final long serialVersionUID = 1L;
public Main() {
getContentPane().setLayout(new MigLayout("", "[grow 30][grow 70]", "[]"));
JLabel label = new JLabel("30%");
getContentPane().add(label, "cell 0 0");
JTextField textField = new JTextField("70%");
getContentPane().add(textField, "cell 1 0,growx");
pack();
setVisible(true);
}
public static void main(String[] args) {
new Main();
}
}
Why the textfield is not appearing on my panel which is inside my frame?
I mean is there some additional action necessary to make the components of the panel
visible?
I hope somebody can help me....
