Images don't painting

[Daniel Lima]

Hello!
This is my first post, and I need your help!
I'm trying to display five images, but I can't. I don't have any error message, any warning!
I have two classes:

Class 1:

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

/**
    The SimpleScreenManager class manages initializing and
    displaying full screen graphics modes.
*/
public class SimpleScreenManager {

    private GraphicsDevice device;

    /**
        Creates a new SimpleScreenManager object.
    */
    public SimpleScreenManager() {
        GraphicsEnvironment environment =
            GraphicsEnvironment.getLocalGraphicsEnvironment();
        device = environment.getDefaultScreenDevice();
    }


    /**
        Enters full screen mode and changes the display mode.
    */
    public void setFullScreen(DisplayMode displayMode,
        JFrame window)
    {
        window.setUndecorated(true);
        window.setResizable(false);

        device.setFullScreenWindow(window);
        if (displayMode != null &&
            device.isDisplayChangeSupported())
        {
            try {
                device.setDisplayMode(displayMode);
            }
            catch (IllegalArgumentException ex) {
                // ignore - illegal mode for this device
            }
        }
    }


    /**
        Returns the window currently used in full screen mode.
    */
    public Window getFullScreenWindow() {
        return device.getFullScreenWindow();
    }


    /**
        Restores the screen's display mode.
    */
    public void restoreScreen() {
        Window window = device.getFullScreenWindow();
        if (window != null) {
            window.dispose();
        }
        device.setFullScreenWindow(null);
    }

}

Class 2:

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

public class ImageTest extends JFrame {

    public static void main(String[] args) {

        DisplayMode displayMode;

        if (args.length == 3) {
            displayMode = new DisplayMode(
                Integer.parseInt(args[0]),
                Integer.parseInt(args[1]),
                Integer.parseInt(args[2]),
                DisplayMode.REFRESH_RATE_UNKNOWN);
        }
        else {
            displayMode = new DisplayMode(800, 600, 16,
                DisplayMode.REFRESH_RATE_UNKNOWN);
        }

        ImageTest test = new ImageTest();
        test.run(displayMode);
    }

    private static final int FONT_SIZE = 24;
    private static final long DEMO_TIME = 2000;

    private SimpleScreenManager screen;
    private Image bgImage;
    private Image opaqueImage;
    private Image transparentImage;
    private Image translucentImage;
    private Image antiAliasedImage;
    private boolean imagesLoaded;

    public void run(DisplayMode displayMode) {
        setBackground(Color.blue);
        setForeground(Color.white);
        setFont(new Font("Dialog", Font.PLAIN, FONT_SIZE));
        imagesLoaded = false;

        screen = new SimpleScreenManager();
        try {
            screen.setFullScreen(displayMode, this);
            loadImages();
            try {
                Thread.sleep(DEMO_TIME);
            }
            catch (InterruptedException ex) { }
        }
        finally {
            screen.restoreScreen();
        }
    }


    public void loadImages() {
        bgImage = loadImage("images/background.jpg");
        opaqueImage = loadImage("images/opaque.png");
        transparentImage = loadImage("images/transparent.png");
        translucentImage = loadImage("images/translucent.png");
        antiAliasedImage = loadImage("images/antialiased.png");
        imagesLoaded = true;
        // signal to AWT to repaint this window
        repaint();
    }


    private Image loadImage(String fileName) {
        return new ImageIcon(fileName).getImage();
    }


    public void paint(Graphics g) {
        // set text anti-aliasing
        if (g instanceof Graphics2D) {
            Graphics2D g2 = (Graphics2D)g;
            g2.setRenderingHint(
                RenderingHints.KEY_TEXT_ANTIALIASING,
                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        }

        // draw images
        if (imagesLoaded) {
            g.drawImage(bgImage, 0, 0, null);
            drawImage(g, opaqueImage, 0, 0, "Opaque");
            drawImage(g, transparentImage, 320, 0, "Transparent");
            drawImage(g, translucentImage, 0, 300, "Translucent");
            drawImage(g, antiAliasedImage, 320, 300,
                "Translucent (Anti-Aliased)");
        }
        else {
            g.drawString("Loading Images...", 5, FONT_SIZE);
        }
    }


    public void drawImage(Graphics g, Image image, int x, int y,
        String caption)
    {
        g.drawImage(image, x, y, null);
        g.drawString(caption, x + 5, y + FONT_SIZE +
            image.getHeight(null));
    }

}

I see the background, and the Strings, but no images :-(

Any help will be great!

Thank you in advance!

Try using now. Hope this will help you

Hello Vijay Kakade !
Tnx for your reply!

This don't work. I've tryed...

I don't know what's happening.... I looked the code thousands of times!

Please try test this code in your computer...

Tnx in advance!

Are all images in classpath? Put that in classpath It should display the images.

[Daniel Lima]

Add information:

I've edited the .classpath file, no success.
I've edited the run configurations, no succes.

Hello!
More information!

if i do this:

public void loadImages() {
        bgImage = loadImage("C:/daniel/workspace/ImageTest/src//images/background.jpg");
        opaqueImage = loadImage("/images/opaque.png");
        transparentImage = loadImage("C:/daniel/workspace/ImageTest/src/images/transparent.png");
        translucentImage = loadImage("C:/daniel/workspace/ImageTest/src//images/translucent.png");
        antiAliasedImage = loadImage("C:/daniel/workspace/ImageTest/src//images/antialiased.png");
        imagesLoaded = true;
        // signal to AWT to repaint this window
        repaint();
    }

It works!
But I think that I can't put the absolute path im my aplication...

Resolved with:

  
private Image loadImage(String fileName) {
        //return new ImageIcon(fileName).getImage();
    	try 
    	{  
    		return ImageIO.read(getClass().getResource(fileName));  
    	}
    	catch (IOException e) 
    	{  
    		throw new RuntimeException("Unable to load image " + fileName, e);  
	    }  
    }
