Saving File Chooser settings

As far as keeping the same size on your JFileChooser, here's an easy example.

import java.awt.Dimension;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.ComponentEvent;

import java.awt.event.ComponentAdapter;

import javax.swing.JButton;

import javax.swing.JFileChooser;

import javax.swing.JFrame;

public class FileChooserSaveExample extends JFrame

{

//DATA

private JFileChooser fileChooser;

//GUI

private JButton openFileChooserButton;

public FileChooserSaveExample()

{

this.setSize(new Dimension(200,200));

this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

this.setContentPane(getOpenFileChooserButton());

this.setVisible(true);

}

//DATA

private JFileChooser getFileChooser()

{

if(fileChooser == null)

{

fileChooser = new JFileChooser();

fileChooser.addComponentListener(new ComponentAdapter()

{

public void componentResized(ComponentEvent e)

{

fileChooser.setPreferredSize(new Dimension(fileChooser.getSize().width,fileChooser.getSize().height));

}

});

}

return fileChooser;

}

//GUI

private JButton getOpenFileChooserButton()

{

if(openFileChooserButton == null)

{

openFileChooserButton = new JButton("Open File Chooser");

openFileChooserButton.addActionListener(new ActionListener()

{

public void actionPerformed(ActionEvent e)

{

getFileChooser().showOpenDialog(FileChooserSaveExample.this);

}

});

}

return openFileChooserButton;

}

public static void main(String args[])

{

new FileChooserSaveExample();

}

}

Sunan,

I liked your thoughts on this problem.

Do you know if these settings are saved in a user's home area, or could other users pick up the settings made by someone else? On a SUN system running UNIX, it said the preferences were in the user's preferences file, but then it gave the name of "absolute path" as being the root directory, "/". Unfortunately, the "absolute path" that Java returns doesn't tell me much about where Java is storing the information!

Thanks for your response.

If you use userroot() then other users cannot use that users settings.

You can use systemroot() to share between users.

The absolute path will give the path of the node in the tree only. It will not give the path it is stored in the system.

I dont know where the informations are saved. please tell me if you could find.
