    Question only ~200x200px Applet area visible

    Hi Everybody,

    I'm writing a GUI in Java under Linux (FC 9) using Easy Eclipse Desktop Java 1.2.2.
    I'm still not a Java expert, so I depend much on Visual Editor. I'm planning to embed my GUI on a web page, so I chose Applet.
    The problem is as mentioned in the topic. When I "Run As Java Applet" I see an Applet window with the dimensions I declared, but there's only a limited area (200x200px visible), the rest is just gray:

    212.67.142.162/pub/zrzutekranu.png (sorry for that, but I'm not allowed to post links to photos)
    EDIT:--------
    alternative link: www[dot]fotosik[dot]pl/showFullSize.php?id=ad892da888429074
    ---------------

    And here's my example code:
    Java Code: 
    import java.awt.BorderLayout;
import javax.swing.JPanel;
import javax.swing.JApplet;
import javax.swing.JTextPane;
import javax.swing.JButton;
import java.awt.Dimension;
import java.awt.event.KeyEvent;

public class Problem extends JApplet {

	private JPanel jContentPane = null;
	private JTextPane jTextPane = null;
	private JButton jButton = null;
	private JButton jButton1 = null;

	/**
	 * This is the xxx default constructor
	 */
	public Problem() {
		super();
	}

	/**
	 * This method initializes this
	 * 
	 * @return void
	 */
	public void init() {
		this.setSize(300, 200);
		this.setContentPane(getJContentPane());
	}

	/**
	 * This method initializes jContentPane
	 * 
	 * @return javax.swing.JPanel
	 */
	private JPanel getJContentPane() {
		if (jContentPane == null) {
			jContentPane = new JPanel();
			jContentPane.setLayout(new BorderLayout());
			jContentPane.add(getJTextPane(), BorderLayout.CENTER);
			jContentPane.add(getJButton(), BorderLayout.SOUTH);
			jContentPane.add(getJButton1(), BorderLayout.NORTH);
		}
		return jContentPane;
	}

	/**
	 * This method initializes jTextPane	
	 * 	
	 * @return javax.swing.JTextPane	
	 */
	private JTextPane getJTextPane() {
		if (jTextPane == null) {
			jTextPane = new JTextPane();
		}
		return jTextPane;
	}

	/**
	 * This method initializes jButton	
	 * 	
	 * @return javax.swing.JButton	
	 */
	private JButton getJButton() {
		if (jButton == null) {
			jButton = new JButton();
			jButton.setPreferredSize(new Dimension(34, 30));
			jButton.setMnemonic(KeyEvent.VK_UNDEFINED);
		}
		return jButton;
	}

	/**
	 * This method initializes jButton1	
	 * 	
	 * @return javax.swing.JButton	
	 */
	private JButton getJButton1() {
		if (jButton1 == null) {
			jButton1 = new JButton();
			jButton1.setPreferredSize(new Dimension(34, 30));
			jButton1.setText("ABCDEFGHIJKLMNOP1234567890");
		}
		return jButton1;
	}
}
    What could be the problem?
    I will appreciate any of your help or hints.

    Best regards

    PS. When I do "Applet -> Clone..." from Applet's menu it works fine...

    Seems to me this is something wrong with the applet viewer. Your code is fine. Did you try to add into a html page, you'll see the applet in correct way.

    Yepp, you were right! :) However something is still "thinking" the applet is 200x200, because the html code that Eclipse generated was:

    XML Code: 
    <html>
<body>
<applet code=Covert.class width="200" height="200" >
</applet>
</body>
</html>
    I had to correct it to 800x480.
    Any way to change the applet viewer?

    Thanx a lot
    cheers

    Your applet code, I mean the HTML code above, set the size of the applet into 200 X 200. Since I'm not an Eclipse use I don't know the exact way to do this.

    Can you edit the above HTML code? If so try to change them into 800 X 480, size you want to have and try.

    Eclipse uses (I think) the standard java appletviewer. I'm not sure how to set the applet's size using this though. I'm with you Eranga, just create a simple HTML page and adjust the size in the HTML code.

    Sure, I can do that in HTML and that works (the applet is as big as i wish), but I wonder why it's 200x200 by default even though it's set to be 300x200 (or whatever) in Java source.

    As Fubarable says, IDE use the standard applet viewer. Somehow because of a reason it not functioning properly. If you change the size of the code, it's effected on the applet viewer. On side side it's working fine.
