Java dynamic gui help

[Ali Bm]

Hello,

I posted this question the other day in SomeOtherForum.com Java-forums.org, but wasn't able to get a good answer, so now I'm asking here...
I have a project and I'm working on the important part now.
I want to create this interface in the end and informations in DB.
This my goal, this is a prototypical interface created with MockupScreens


now I created this interface, I think I'm progressing slowly because I made it in one day
it needs more work on...
This is the ouput:


This interface is composed by :
- one columnPanel with a GridLayout
- a rowPanel which contains the 5 buttons : ( title of row + up + down + delete + add)

Now I created the add button but itsn't woks like I want.
It adds rowPanel in columnPanel. For example when I click add buttton on row N°0 60, the next rowPanel will be in the end of list not just after.
I want the new rowPanel appear between N°0 60 and N°0 13 .

I added a random number with number of row to differentiate between rowPanels.
Someone have an idea.
I tryed to print the index of rowpanel using getComponent() but it always gives 0.

int index = 0;
rowPanel.getComponent(index);

Here's my full code:

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.EventQueue;
import javax.swing.BorderFactory;
import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import java.awt.Color;
import java.awt.GridLayout;
import javax.swing.JScrollPane;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JTextField;
import javax.swing.JTextArea;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.util.Random;
public class Test_DG extends JFrame {
	private JPanel contentPane;
	static int nbrows;
	JPanel columnPanel = new JPanel();
	JButton btnStart = new JButton("Start");
	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		nbrows=0;
		Test_DG frame = new Test_DG();
		frame.setVisible(true);	 
	}

	/**
	 * Create the frame.
	 */
	public Test_DG() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 637, 441);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		btnStart.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent arg0) {
				addRow();
			}
		});
		btnStart.setBounds(349, 21, 78, 23);
		contentPane.add(btnStart);
		columnPanel.setBounds(29, 24, 310, 368);
		contentPane.add(columnPanel);
		
		columnPanel.setBackground(Color.ORANGE);
		columnPanel.setLayout(new GridLayout(13, 1, 0, 2));
			
	}
	
	  void addRow() {
		   
		    JPanel rowPanel = new JPanel();
		    rowPanel.setLayout(null);
		    
		    JButton lbl = new JButton("");
			Random randGen = new Random();
		    lbl.setText("N°"+nbrows +" "+randGen.nextInt(8) +randGen.nextInt(8));
		    ///////////////////
		    nbrows++;
		    ////////////////////
		    lbl.setBounds(0, 3, 95, 18);
		    rowPanel.add(lbl);
		    //////////////////////////////////	
		    JButton btnUp = new JButton("^");
		    btnUp.setBounds(95, 3, 45, 18);
			rowPanel.add(btnUp);
			
			JButton btnDown = new JButton("V");
			btnDown.setBounds(139, 3, 45, 18);
			rowPanel.add(btnDown);
			
		    JButton btnDel = new JButton("Del");
		    btnDel.setBounds(185, 3, 55, 18);
			rowPanel.add(btnDel);
			///////////////////////////////////////
			
		    JButton btnAdd = new JButton("Add");
			btnAdd.setBounds(241, 3, 65, 18);
			rowPanel.add(btnAdd);
			int index = 0;
			rowPanel.getComponent(index);
			System.out.println(index);
			btnAdd.addActionListener(new ActionListener() {
				public void actionPerformed(ActionEvent arg0) {
					addRow(); //////// ISNT RECURSION HERE ??
					
				}
			});
			
			//int index = 0;
			rowPanel.getComponent(index);
			System.out.println(index);
			
			btnDel.addActionListener(new ActionListener() {
				public void actionPerformed(ActionEvent arg0) {
 					//columnPanel.remove(this.rowPanel);
				}
			});
			 
			columnPanel.add(rowPanel);
		    columnPanel.validate();
		    columnPanel.repaint();
		    ////////////////////////////////////
		    
		  } 
}

Also I wouldn't start adding rowPanels by the start button,
I created it because it call the addRow method and the first rowPanel won't appear.

Waiting for your response.
Thanks in advance.
Best regrads,
Ali.

Sorry brothers,
I posted this question the other day in Java-forums.org, but wasn't able to get a good answer, so now I'm asking here...

And that's fine, but you should tell us that you've posted the same question on other boards, and tell the people on the other boards that you have posted the question here; Darryl's link to BeForthrightWhenCrossPostingToOtherSites says why.

And you should follow the advice from Darryl's point 3.
