Java Application JEditorPane + ScrollBar/ Pane? plz help

[Eremis]

Hi everybody!

I am still working on my Java senior project (high school, topic: Open Source), and I encountered a problem with my gui. I dont know how to add ScrollBars to JEditorPane. So if you could give me a simple code sample, or point me into a tutorial I would appreciate it.

I attached a screen-shot showing you my gui so far, and photoshoped it to show you want I am talking about.

The Code is below:




// Imports
import java.awt.*;
import java.net.URL;
import javax.swing.BoxLayout;
import javax.swing.Box;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JButton;
import javax.swing.JEditorPane;
import javax.swing.ImageIcon;
import javax.swing.AbstractButton;

public class Open_EncryptGUI
{
// private variables
private ImageIcon newButtonIcon = createImageIcon("images/new.png");
private ImageIcon saveButtonIcon = createImageIcon("images/save.png");
private ImageIcon encryptButtonIcon = createImageIcon("images/encrypt.png");
private ImageIcon decryptButtonIcon = createImageIcon("images/decrypt.png");
private ImageIcon sendButtonIcon = createImageIcon("images/send.png");
private JButton newButton = new JButton("New", newButtonIcon);
private JButton saveButton = new JButton("Save", saveButtonIcon);
private JButton encryptButton = new JButton("Encrypt", encryptButtonIcon);
private JButton decryptButton = new JButton("Decrypt", decryptButtonIcon);
private JButton sendButton = new JButton("Send", sendButtonIcon);
private JEditorPane text = new JEditorPane();

// Top panel of the GUI
private class ButtonPanel extends JPanel
{
public ButtonPanel()
{
setLayout(new BoxLayout(this, BoxLayout.X_AXIS));

newButton.setVerticalTextPosition(AbstractButton.B OTTOM);
newButton.setHorizontalTextPosition(AbstractButton .CENTER);
saveButton.setVerticalTextPosition(AbstractButton. BOTTOM);
saveButton.setHorizontalTextPosition(AbstractButto n.CENTER);
encryptButton.setVerticalTextPosition(AbstractButt on.BOTTOM);
encryptButton.setHorizontalTextPosition(AbstractBu tton.CENTER);
decryptButton.setVerticalTextPosition(AbstractButt on.BOTTOM);
decryptButton.setHorizontalTextPosition(AbstractBu tton.CENTER);
sendButton.setVerticalTextPosition(AbstractButton. BOTTOM);
sendButton.setHorizontalTextPosition(AbstractButto n.CENTER);

add(Box.createRigidArea(new Dimension(10, 0)));
add(newButton);
add(Box.createRigidArea(new Dimension(30, 0)));
add(saveButton);
add(Box.createHorizontalGlue());
add(Box.createRigidArea(new Dimension(200, 0)));

add(encryptButton);
add(Box.createRigidArea(new Dimension(30, 0)));
add(decryptButton);
add(Box.createRigidArea(new Dimension(30, 0)));
add(sendButton);
add(Box.createRigidArea(new Dimension(10, 0)));
}
}

// Bottom Panel of the GUI
private class EditorPanel extends JPanel
{
public EditorPanel()
{
setLayout(new BoxLayout(this, BoxLayout.X_AXIS));

add(Box.createRigidArea(new Dimension(10, 0)));
add(text);
add(Box.createRigidArea(new Dimension(10, 0)));
}
}

// The Whole Panel as one
private class EncryptorPanel extends JPanel
{
public EncryptorPanel()
{
ButtonPanel bp = new ButtonPanel();
EditorPanel ep = new EditorPanel();
Dimension dim = new Dimension(732, 500);

setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
setPreferredSize(dim);
setMinimumSize(dim);

add(Box.createRigidArea(new Dimension(0, 10)));
add(bp);
add(Box.createRigidArea(new Dimension(0, 10)));
add(ep);
add(Box.createRigidArea(new Dimension(0, 10)));
}

}

// JFrame containiang the EncryptorPanel
private class EncryptorJFrame extends JFrame
{
public EncryptorJFrame()
{
EncryptorPanel panel = new EncryptorPanel();
Dimension dim = new Dimension(732, 500);
setPreferredSize(dim);
setMinimumSize(dim);

setTitle("Open Crypt 1.0");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(panel);
pack();
setResizable(true);
setVisible(true);
}
}

// Returns an ImageIcon, or null if the path was invalid.
// Used for Button Icons
protected ImageIcon createImageIcon(String path)
{
URL imgURL = getClass().getResource(path);

if (imgURL != null)
{
return new ImageIcon(imgURL);
}
else
{
System.err.println("Couldn't find file: " + path);
return null;
}
}

// Runs the GUI
public void run()
{
EncryptorJFrame frame = new EncryptorJFrame();
}

/* Tester

public static void main(String[] args)
{
Open_EncryptGUI gui = new Open_EncryptGUI();
gui.run();
}

*/
}


P.S.

I tried adding a "ScrollBar" to EditorPanel(), when I tried that it visually added it, but when I typed a lot of stuff, the scroolbar moved down with the text, so I was not able to see it.

Thanks a lot!

I'd suggest Sun's swing tutorial, it's quite good:

http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html

Also here's an example of an JEditorPane with a scrollpane:

Good luck with your project
