I have a JFrame and i need to add panels to it where i like, but I am not sure how to do it. I have tried all the layouts but i cant get what i want.
Basically FunProgramming is the main frame and I need 3 other panels on that frame. i need one in the middle/right. i need a panel to the left and one across the bottom and about 1/3 up the frame. After trying the different layout managers I'm not sure how to go about doing this(also sorry, i couldn't seem to separate the two classes, the first one it now missing a {)
import java.awt.BorderLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
public class FunProgrammingFrame {
private JFrame frame;
private JMenuBar menuBar;
private JMenu menu;
private JMenuItem menuItem;
private final String M_ITEM_ONE = "File", M_ITEM_TWO = "Project", M_ITEM_THREE = "Help", ITEM_ONE = "New", ITEM_TWO = "Open", ITEM_THREE = "Save", ITEM_FOUR = "Quit";
public FunProgrammingFrame(){
ConsolePanel consolePanel = new ConsolePanel();
frame = new JFrame("Fun Programming");
frame.setLayout(new GridBagLayout());
//frame.add(consolePanel, BorderLayout.SOUTH);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
menuBar = new JMenuBar();
createMenu(M_ITEM_ONE);
addMenuItem(ITEM_ONE);
menuItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
}
});
addMenuItem(ITEM_TWO);
menuItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
}
});
addMenuItem(ITEM_THREE);
menuItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
}
});
menu.addSeparator();
addMenuItem(ITEM_FOUR);
menuItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
System.exit(0);
}
});
createMenu(M_ITEM_TWO);
createMenu(M_ITEM_THREE);
//addPanel(consolePanel, 10, 10, GridBagConstraints.SOUTH);
frame.setVisible(true);
}
public void createMenu(String name){
menu = new JMenu(name);
menuBar.add(menu);
frame.setJMenuBar(menuBar);
}
public JMenuItem addMenuItem( String itemName) {
menuItem = new JMenuItem(itemName);
menu.add(menuItem);
return menuItem;
}
public static void main(String[] args){
FunProgrammingFrame fp = new FunProgrammingFrame();
}
}
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JPanel;
public class ConsolePanel extends JPanel{
private JPanel Cpanel;
private final int WIDTH = 100, HEIGHT = 500;
public ConsolePanel(){
Cpanel = new JPanel(new BorderLayout());
Cpanel.setSize(WIDTH, HEIGHT);
Cpanel.setVisible(true);
setBackground(Color.BLACK);
}
}

You can try something like this:
public class Test {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
MBar mBar = new MBar();
TextAreaPanel scrPan = new TextAreaPanel();
BottomPan pan = new BottomPan();
ButtonsPanel buttsCon = new ButtonsPanel();
f.setJMenuBar(mBar);
f.getContentPane().add(buttsCon, BorderLayout.LINE_START);
f.getContentPane().add(scrPan, BorderLayout.CENTER);
f.getContentPane().add(pan, BorderLayout.PAGE_END);
f.pack();
f.setVisible(true);
}
});
}
}
ButtonsPanel.java
public class ButtonsPanel extends JPanel {
public ButtonsPanel() {
setLayout(new BoxLayout(this, BoxLayout.X_AXIS));
add(Box.createHorizontalStrut(50));
JPanel butts = new JPanel();
butts.setLayout(new BoxLayout(butts, BoxLayout.Y_AXIS));
butts.add(Box.createVerticalStrut(30));
for (int i = 0; i < 5; i++) {
JButton butt = new JButton("Button " + String.valueOf(i));
butts.add(butt);
butts.add(Box.createVerticalStrut(10));
}
butts.setAlignmentY(JPanel.TOP_ALIGNMENT);
butts.add(Box.createVerticalStrut(40));
add(butts);
add(Box.createHorizontalStrut(50));
}
}
TextAreaPanel.java
public class TextAreaPanel extends JScrollPane {
public TextAreaPanel() {
JTextArea jtxtArea = new JTextArea();
setViewportView(jtxtArea);
}
}
BottomPan.java
public class BottomPan extends JPanel {
public BottomPan() {
setBackground(Color.black);
setPreferredSize(new Dimension(100, 100));
}
}
MBar.java
public class MBar extends JMenuBar {
public MBar() {
for (int i = 0; i < 5; i++) {
JMenuItem mi = new JMenuItem("Menu Item " + String.valueOf(i));
add(mi);
}
}
}

Something like...
import java.awt.Color;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.border.LineBorder;
public class Test {
public static void main(String[] args) {
new Test();
}
public Test() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new ContentPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class ContentPane extends JPanel {
public ContentPane() {
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.fill = GridBagConstraints.BOTH;
gbc.weighty = 0.7;
add(new TestPane(Color.RED), gbc);
gbc.weightx = 1;
gbc.fill = GridBagConstraints.BOTH;
gbc.gridx++;
add(new TestPane(Color.BLUE), gbc);
gbc.gridy = 1;
gbc.gridx = 0;
gbc.weighty = 0.3;
gbc.weightx = 1;
gbc.gridwidth = GridBagConstraints.REMAINDER;
gbc.fill = GridBagConstraints.BOTH;
gbc.anchor = GridBagConstraints.NORTH;
add(new TestPane(Color.GREEN), gbc);
}
}
public class TestPane extends JPanel {
public TestPane(Color color) {
setBorder(new LineBorder(color));
}
@Override
public Dimension getPreferredSize() {
return new Dimension(200, 200);
}
}
}

You can let your main frame be a BorderLayout.
Place your ConsolePanel as follows:
frame.add(consolePanel, BorderLayout.WEST);
consolePanel.setPreferredSize(100, 400);
I'm guessing you will be able to take it from there.
