Need help with JFrame background image

[ProGenius]

Hi. I have a program where I have designed a simple house on the 700x700px screen and want to put a background image. I have the code but the code creates a NEW window so when I run the program I have the house AND the other window with the background image. I was just wondering, does anyone know how to change the code so it applies the background image to the window I am working with without creating a new frame?

Here is the code that creates the background image in a new frame:

public class R extends JPanel{
  public void paint(Graphics g) {
      super.paint(g);        
       
        int c[]={200,200,215,230,245,260,275,290,305,320,335,350,365,380,395,410,425,440,455,470,485,500,500};         //house
        int d[]={300,510,490,510,490,510,490,510,490,510,490,510,490,510,490,510,490,510,490,510,490,510,300};
        g.drawPolygon(c,d,23);    
        g.setColor(Color.yellow);
        g.fillPolygon(c,d,23);
        g.setColor(Color.pink);  
      
      
      
    Graphics2D g2 = (Graphics2D) g;
    RoundRectangle2D r = new RoundRectangle2D.Float(0, 0, 700, 700, 25,
        25);
    RoundGradientPaint rgp = new RoundGradientPaint(50, 50, Color.white,
        new Point2D.Double(350, 350), Color.black);
    g2.setPaint(rgp);
    g2.fill(r);
  }

  class RoundGradientPaint implements Paint {
    protected Point2D point;

    protected Point2D mRadius;

    protected Color mPointColor, mBackgroundColor;

    public RoundGradientPaint(double x, double y, Color pointColor,
        Point2D radius, Color backgroundColor) {
      if (radius.distance(0, 0) <= 0)
        throw new IllegalArgumentException("Radius must be greater than 0.");
      point = new Point2D.Double(x, y);  mPointColor = pointColor;
      mRadius = radius;
      mBackgroundColor = backgroundColor;
    }

    public PaintContext createContext(ColorModel cm, Rectangle deviceBounds,
        Rectangle2D userBounds, AffineTransform xform, RenderingHints hints) {
      Point2D transformedPoint = xform.transform(point, null);
      Point2D transformedRadius = xform.deltaTransform(mRadius, null);
      return new RoundGradientContext(transformedPoint, mPointColor,
          transformedRadius, mBackgroundColor);
    }

    public int getTransparency() {

PS: And also, in my program I am using JFrame not JPanel. Is there anyway I can still make it work? Because when I change my program to JPanel, other stuff doesnt work at all.

Thanks in advance.

Please see (and reply to) your animation thread. There you'll see how to put a JPanel into a JFrame.

Next, to make your image panel the background panel, just give it a layout and add your components to it. If you want added components such as JPanels to show the image through them, be sure to set their opaque property to false via setOpaque(false);

Finally, when drawing on a JPanel, be sure to override paintComponent, not paint.

Hi. Thanks a lot. I will have a look at it and see how it goes.

Thank you for your help. I really apreciate it.

I couldn't resist the temptation to create a resizable SmileyPanel, so here it is :)

import java.awt.*;
import javax.swing.*;

@SuppressWarnings("serial")
class SmileyPanel extends JPanel {
  private static final double EH_RATIO = 1.0/5;
  private static final double EW_RATIO = 1.0/7;
  private static final double EX_RATIO = 1.0/4;
  private static final double EY_RATIO = 1.0/5;
  private static final double SM_RATIO = 1.0/5;
  private static final int SMILE_DEGREES = 75;
  private static final double STROKE_RATIO = 1.0/40;

  protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    int w = getWidth();
    int h = getHeight();
    Graphics2D g2 = (Graphics2D) g;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, 
        RenderingHints.VALUE_ANTIALIAS_ON);
    g2.setColor(Color.yellow);
    g2.fillOval(0, 0, w, h);
    
    int eyeH = (int)(h * EH_RATIO);
    int eyeW = (int)(w * EW_RATIO);
    int eyeX = (int)(w * EX_RATIO);
    int eyeY = (int)(h * EY_RATIO);
    
    g2.setColor(Color.black);
    g2.fillOval(w/2 - eyeX, eyeY, eyeW, eyeH);
    g2.fillOval(w/2 + eyeX - eyeW, eyeY, eyeW, eyeH);
    
    int smileW = w;
    int smileH = h;
    int smileX = 0;
    int smileY = 0 - (int)(h * SM_RATIO);
    Stroke oldStroke = g2.getStroke();
    float stroke = (float)(h * STROKE_RATIO);
    g2.setStroke(new BasicStroke(stroke, 
        BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND));
    g2.drawArc(smileX, smileY, smileW, smileH, 
        270 - SMILE_DEGREES/2, SMILE_DEGREES);
    g2.setStroke(oldStroke);
  }
  
  private static void createAndShowUI() {
    JPanel sPanel = new SmileyPanel();
    sPanel.setPreferredSize(new Dimension(600, 600));
    JFrame frame = new JFrame("SmileyPanel");
    frame.getContentPane().add(sPanel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }

  public static void main(String[] args) {
    java.awt.EventQueue.invokeLater(new Runnable() {
      public void run() {
        createAndShowUI();
      }
    });
  }
}

So now if I want to add components and panels to my SmileyPanel, I can easily do that like so:

import java.awt.*;
import javax.swing.*;

public class SmileyPanelTest {
  private static final Dimension SIZE = new Dimension(600, 600);
  private static final String TITLE = "My Title";
  private static final float TITLE_POINTS = 64;
  private JPanel mainPanel = new SmileyPanel();
  
  public SmileyPanelTest() {
    JLabel titleLabel = new JLabel(TITLE, SwingConstants.CENTER);
    titleLabel.setFont(titleLabel.getFont().deriveFont(Font.BOLD, TITLE_POINTS));
    titleLabel.setForeground(Color.red.darker());
    
    JPanel btnPanel = new JPanel(new GridLayout(1, 0, 25, 0));
    btnPanel.setOpaque(false);
    btnPanel.add(new JButton("Button 1"));
    btnPanel.add(new JButton("Button 2"));
    btnPanel.add(new JButton("Button 3"));
    
    mainPanel.setPreferredSize(SIZE);
    mainPanel.setOpaque(true);
    mainPanel.setBorder(BorderFactory.createEmptyBorder(30, 30, 30, 30));
    mainPanel.setLayout(new BorderLayout(10, 10));
    mainPanel.add(titleLabel, BorderLayout.NORTH);
    mainPanel.add(btnPanel, BorderLayout.SOUTH);
  }
  
  public JPanel getMainPanel() {
    return mainPanel;
  }

  private static void createAndShowUI() {
    JFrame frame = new JFrame("Background Panel");
    frame.getContentPane().add(new SmileyPanelTest().getMainPanel());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }

  public static void main(String[] args) {
    java.awt.EventQueue.invokeLater(new Runnable() {
      public void run() {
        createAndShowUI();
      }
    });
  }
}

Hi. Thanks a lot for your help. I still have cannot get it to work. When I change my program to JPanel stuff doesnt work. Sorry if I am getting a bit annoying but I have been trying to do this for a week now and it still isnt working. :confused: I know my code is a bit too long to be put here but Im still going to put it so you can have a look at it and see what do I need to do to put it into a JPanel. After running my program it creates 2 windows: one is my program and the other one is the frame with a bgimage. Have a look at my code and see what can and cant be done with it.

Hi. Thanks a lot for your help. I still have cannot get it to work. When I change my program to JPanel stuff doesnt work.

This tells us nothing about what you're doing wrong. How are you changing things? How is it not working? Where's the code attempt?

Sorry if I am getting a bit annoying but I have been trying to do this for a week now and it still isnt working. :confused: I know my code is a bit too long to be put here but Im still going to put it so you can have a look at it and see what do I need to do to put it into a JPanel. After running my program it creates 2 windows: one is my program and the other one is the frame with a bgimage. Have a look at my code and see what can and cant be done with it.

Myself, I really don't want to see your JFrame code -- I want to see your attempt at solving this problem and the problems this is causing. So on that note, ...

1) Start small. You're having a problem creating a JPanel, adding things to this JPanel and putting it in a JFrame, so create a small program that tries to do just this and doesn't have all this other junk in it. This way you don't have to deal with side issues not related to this very basic problem.

2) Show us your attempt with this small program and let us know any error messages you may be having and what lines are causing these errors.

Much luck.

Also, I tried to compile your code just to see what the app looked like, but no go due to some class called "R" which we don't have the code for:

  public static void main(String[] args) throws IOException {
    String path = "C:/Users/FiKo/Desktop/java2.jpg";
    BufferedImage image = ImageIO.read(new File(path));
    R contentPane = new R(image); // ***** what is "R"?? *****

So what is "R" and why is it in this code?
