I'm making a street fighter game in java, I have all the background pictures finished, and I'm trying to add the characters onto the background, but in the output the character picture keeps appearing next to the background instead of on top of it. I want the character to appear on top of the background, just like a normal street fighter game.

I'm actually codding a keypad for an application and I'm encountering a problem. I'm using some empty space in the JDialog I'm creating to place an exist button on the top right corner of the Dialog box. This empty space is creating a border to the dialog box which is unpleasant to see. So I've tried to make panels transparent with setOpaque(false) function, but I achieved nothing. Do I have to use the paint function (which I don't know how to use) ?
Here is my test function without the setOpaque tests I've done :

Simple example for making a JFrame transparent:
import java.awt.*;
import static java.awt.GraphicsDevice.WindowTranslucency.TRANSLUCENT;
import javax.swing.*;
class TransparentFrame extends JFrame
{
public TransparentFrame()
{
JPanel panel = new JPanel();
panel.setOpaque( false );
panel.add( new JButton("Button") );
add(panel, BorderLayout.SOUTH);
setUndecorated(true);
setSize(300, 300);
//pack();
// setOpacity(0.5f); // set transparency on frame and components
setBackground( new Color(0, 0, 0, 64) ); // set transparency on frame only
setTitle("Transparent Frame Demo");
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
}
public static void main(String args[])
{
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
// Exit when translucent windows aren't supported
if (!gd.isWindowTranslucencySupported(TRANSLUCENT))
{
System.err.println( "Translucency is not supported" );
System.exit(0);
}
// Create the GUI on the event-dispatching thread
SwingUtilities.invokeLater(() -> new TransparentFrame().setVisible(true));
}
}
How do I make my textfields and button centered?
Edit: Updated my post with SSCE. Hopefully that helps.
By the way, I want the left image to look like the right.

memory extends JFrame. Swing won't let you add a window to another window.
You should avoid extending from top level containers (this is just reason) and instead use something like JPanel.
This allows you to add the component to whatever container you like
JFrame does not have a paintComponent method, so it will never be called. The reason it compiles is that you've called super.paintComponents (note the s at the end).
Instead, you should, extend from something like JPanel and override it's paintComponent method and perform you custom painting from there
My program is about a supermarket. I want to position the JButton 'b1' just below JLabel 'l1' and also below JTextField 'jt1'. I want the JButton 'b1' to also be in the centre but below 'l1' and 'jt1'. Below is the delivery() method of my program:
public static void delivery()
{
final JFrame f1 = new JFrame("Name");
f1.setVisible(true);
f1.setSize(600,200);
f1.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f1.setLocation(700,450);
JPanel p1 = new JPanel();
final JLabel l1 = new JLabel("Enter your name: ");
final JTextField jt1 = new JTextField(20);
JButton b1 = new JButton("Ok");
b1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
input1 = jt1.getText();
f1.setVisible(false);
}
});
p1.add(b1);
p1.add(l1);
p1.add(jt1);
f1.add(p1);
final JFrame f2 = new JFrame("Address");
f2.setVisible(true);
f2.setSize(600,200);
f2.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f2.setLocation(700,450);
JPanel p2 = new JPanel();
final JLabel l2 = new JLabel("Enter your address: ");
final JTextField jt2 = new JTextField(20);
JButton b2 = new JButton("Ok");
b2.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
input2 = jt2.getText();
f2.setVisible(false);
}
});
p2.add(b2);
p2.add(l2);
p2.add(jt2);
f2.add(p2);
}
}
You can use multiple JPanels to get close to what you want:
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class MyGui {
public static void delivery()
{
JFrame f1 = new JFrame("Name");
f1.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f1.setBounds(200, 100, 500, 300);
Container cpane = f1.getContentPane();
JPanel p1 = new JPanel();
p1.setLayout(new BoxLayout(p1, BoxLayout.LINE_AXIS)); //Horizontal
JLabel l1 = new JLabel("Enter your name: ");
JTextField jt1 = new JTextField(20);
jt1.setMaximumSize( jt1.getPreferredSize() );
p1.add(l1);
p1.add(jt1);
JPanel p2 = new JPanel();
p2.setLayout(new BoxLayout(p2, BoxLayout.PAGE_AXIS)); //Vertical
p2.add(p1);
JButton b1 = new JButton("Ok");
p2.add(b1);
cpane.add(p2);
f1.setVisible(true);
}
}
public class SwingProg {
private static void createAndShowGUI() {
MyGui.delivery();
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}
Use the GridBagLayout Class. It's for custom designing using Constraints.
I'm getting an error at the line: jFrame cannot be resolved
jFrame.setTitle(titleName.getText());
public void createOption(){
Option = new JPanel();
Option.setLayout( null );
JLabel TitleLabel = new JLabel("Change the company name");
TitleLabel.setBounds(140, 15, 200, 20);
Option.add(TitleLabel);
titleName = new JTextField();
titleName.setBounds(90,40,260,20);
Option.add(titleName);
JButton Change = new JButton("Change New Name");
Change.setBounds(90,80,150,20);
Change.addActionListener(this);
Change.setBackground(Color.white);
Option.add(Change);
JButton Exit = new JButton("Exit");
Exit.setBounds(270,80,80,20);
Exit.addActionListener(this);
Exit.setBackground(Color.white);
Option.add(Exit);
Change.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
jFrame.setTitle(titleName.getText());
}
});
}
You will have to have a reference to your JFrame. Assuming button and textBox for the names for the controls, you can do
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
jFrame.setTitle(textBox.getText());
}
});
EDIT:
Here's a full example
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class JFrameExample {
public static void main(String[] args) {
final JFrame jFrame = new JFrame("This is a test");
jFrame.setSize(400, 150);
Container content = jFrame.getContentPane();
content.setBackground(Color.white);
content.setLayout(new FlowLayout());
final JTextField jTextField = new JTextField("TestTitle");
content.add(jTextField);
final JButton button = new JButton("Change");
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
jFrame.setTitle(jTextField.getText());
}
});
content.add(button);
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jFrame.setVisible(true);
}
