Below is the code that I have worked on for Registration class..

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

	}
	
	class UploadListener implements ActionListener
	{
		public void actionPerformed(ActionEvent evt)
		{
			FileChooser fc = new FileChooser();
			fc.FileChooser();
		}
	}
	
	public static void main(String[] args)
	{
		Registration r = new Registration();
	}
		
}		 

And here is another class of FileChooser

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.text.*;
import java.io.*;
import javax.swing.filechooser.*;

public class FileChooser extends JFrame implements ActionListener
{
	JLabel file;
	JButton browse, cancel, ok;
	JTextField field3;	
	JPanel jpBrowser1, jpBrowser2;
	JFileChooser fc;
	
	public void FileChooser() {
		setTitle("Upload Picture");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setLayout(new BorderLayout());
		setSize(400,110);
		
		fc = new JFileChooser();
		
		file = new JLabel("File");
		
		browse = new JButton("Browse");
		cancel = new JButton("Cancel");
		ok = new JButton("Ok");
		
		field3 = new JTextField(20);
		
		browse.addActionListener(this);
		
		jpBrowser1 = new JPanel();
		jpBrowser1.setLayout(new FlowLayout());
		
		jpBrowser2 = new JPanel();
		jpBrowser2.setLayout(new FlowLayout());
		
		jpBrowser1.add(file);
		jpBrowser1.add(field3);
		jpBrowser1.add(browse);
		
		jpBrowser2.add(cancel);
		jpBrowser2.add(ok);
		
		add(jpBrowser1, "North");
		add(jpBrowser2, "East");
		
		setVisible(true);
		
	}
	
		public void actionPerformed(ActionEvent e)
		{	
			if (e.getSource() == browse) {
				int returnVal = fc.showOpenDialog(FileChooser.this);

				if (returnVal == JFileChooser.APPROVE_OPTION) {
					File file = fc.getSelectedFile();
					field3.setText(file.getName());
				}
			}
		}

}

So my question is when you run the program, you could see that the gap between 'Name' and 'NRIC', 'NRIC' and 'Student ID', and so on, is so big, how can i actually decrease the gap?
I've tried to use the 'setLayout(new GridLayout(7,1,0,20)'
hoping that int 20 will adjust the gap. But it was to no avail.

Secondly, when I click on 'upload' button, a 'upload picture' window for us to choose a file later on will pop up.
My question here is when user clicks on the 'cancel' button, what method can I implement to close the 'upload picture' window and return to previous one?

Thirdly, when user is touching on 'upload picture' window, user can actually navigate around the 'registration' window.
How can I prevent such condition? Maybe like, freezing the 'registration' window until the 'upload picture' has been closed.

Thx for helping.

That is what GridLayout are for
If you increase/decrease the size of the frame all the components will reajust their size accordingly and they will have all the same size
You might pad with emply JLabel

Make you FileChoser fc variable an instance variable (a variable of the class so anybody can see it) do not declare it in the ActionListener. In the ActionListenr just do:

fc = new FileChooser();

So now your other ActionListener can see it and do fc.dispose();

uploadwindow.setFocusable(false);

[musizian]

I'm not clear on your explanation. Can you tell me where should I write the code for the fc.dispose() and uploadwindow.setFocusable(false).
THX..

In the ActionListener of the "cancel" button

and uploadwindow.setFocusable

Just after creating the uploadwindow.

[musizian]

Is the place where I declared the variable correct?

public class Registration extends JFrame
{
	FileChooser fc
	JLabel jlblName1, jlblName2, jlblNRIC, jlblStudentID, jlblStaffID, jlblDepartment1, jlblDepartment2, jlblUsername1, jlblUsername2, jlblPassword1, jlblPassword11, jlblPassword2, jlblImg;
	JPasswordField jtfPassword1, jtfPassword11, jtfPassword2;
	JTextField jtfname1, jtfname2, jtfNRIC, jtfID1, jtfID2, jtfUsername1, jtfUsername2;
	JButton jbtnUpload, jbtnRegister1, jbtnRegister2, jbtnCheck;
	JComboBox jcbDepartment1, jcbDepartment2;
	JTabbedPane jtpPanel;
	JPanel jp1, jp2;

Then for the fc.dispose();

class CancelHandler implements ActionListener
		{
			public void actionPerformed(ActionEvent e)
			{
				fc.dispose();
			}
		}

I don't need to declare FileChooser fc inside the FileChooser class anymore rite? Or do I?

setFocusable(false);

public FileChooser() {
		setTitle("Upload Picture");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setLayout(new BorderLayout());
		setSize(400,110);
		.
		.
		.
		setVisible(true);
		setFocusable(false);
	}

I did all this, but it doesnt seem to work

Yes this correct

Then for the fc.dispose();

class CancelHandler implements ActionListener
		{
			public void actionPerformed(ActionEvent e)
			{
				fc.dispose();
			}
		}

This is correct again

Yes you still need the JFileChooser in your own FileChooser class

setFocusable(false);

public FileChooser() {
		setTitle("Upload Picture");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setLayout(new BorderLayout());
		setSize(400,110);
		.
		.
		.
		setVisible(true);
		setFocusable(false);	<-------  NO
	}

NO !!! You are making your FileChooser not focusable ... it is its father (Registration) that you do not want to be focusable
You will have to pass this frame to your Listener wehen you create it so It will be able to make it not focusable

[code]

jbtnUpload.addActionListener(new UploadListener(this)); // <--- tell who I am
...

class UploadListener implements ActionListener
{
JFrame frameToDisable;
// Constructor
UploadListener(Registration frame)
{
frameToDisable = frame; // save who is my father
}

public void actionPerformed(ActionEvent evt)
{
fc = new FileChooser();
frameToDisable.setFocusable(false);
}
}

[/quote]

[musizian]

It didnt work again...
the fc.dispose() gave a nullpointerexception error when i click the 'cancel' button.

And I tried to implement ur code of the UploadListener, it could compile, but Registration frame is still focusable.

Could you please write the code in my source code and paste it here.
I know this seems too much but please..

Sir..

It fails to open the FileChooser window.

Surely not my changes that make that
If it does not open now, it didn't open before

i'll try to fix that

OK happy programming... I'll close the topic
