java GroupLayout scrollbar
Could someone please tell me how what and where I need to add something so that each area would have scroll bar?
I am trying to get a scrollbar for my text area but I'm failing all over again!
I created GroupLayout as you can see...
import java.awt.*;
import java.awt.event.*;
import java.util.Date;
import javax.swing.*;
import java.net.*;
import java.io.IOException;
public class GUIriks extends JFrame implements ActionListener{
JButton poga1 = new JButton("Poga 1"); //Definejam gui komponentes
JTextArea area1 = new JTextArea(30,20); //Definejam gui komponentes
JButton poga2 = new JButton("Poga 2"); //Definejam gui komponentes
JTextArea area2 = new JTextArea(30,20); //Definejam gui komponentes
JButton poga3 = new JButton("Poga 3"); //Definejam gui komponentes
JTextArea area3 = new JTextArea(30,20); //Definejam gui komponentes
JButton poga4 = new JButton("Poga 4"); //Definejam gui komponentes
JTextArea area4 = new JTextArea(30,20); //Definejam gui komponentes
public GUIriks(){
super("GUI Rīks");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container content = getContentPane();
content.setBackground(Color.gray);
GroupLayout layout = new GroupLayout(getContentPane());
getContentPane().setLayout(layout);

So, it's kind of hard to know exactly what you're doing, but my guess is you're taking code that was generated by a form editor and are trying to modify it to suit your new needs
But you're basic problem is, you're adding the JTextArea's to the content panel, wrapping them in JScrollPanes, but then adding them back to the content pane via the layout ... which is just a mess.
Instead, your constructor should look like this...
content.add(poga1);
//content.add(area1);
content.add(poga2);
//content.add(area2);
content.add(poga3);
//content.add(area3);
content.add(poga4);
//content.add(area4);
JScrollPane scrollPane1 = new JScrollPane(area1);
JScrollPane scrollPane2 = new JScrollPane(area2);
JScrollPane scrollPane3 = new JScrollPane(area3);
JScrollPane scrollPane4 = new JScrollPane(area4);
content.add(scrollPane1, BorderLayout.WEST);
content.add(scrollPane2, BorderLayout.NORTH);
content.add(scrollPane3, BorderLayout.EAST);
content.add(scrollPane4, BorderLayout.EAST);
poga1.addActionListener(this);
poga2.addActionListener(this);
poga3.addActionListener(this);
poga4.addActionListener(this);
poga1.setBackground(new Color(175, 238, 238));
poga2.setBackground(new Color(255, 182, 193));
poga3.setBackground(new Color(211, 211, 211));
poga4.setBackground(new Color(152, 251, 152));
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.LEADING)
.addComponent(poga1)
.addComponent(poga2)
.addComponent(poga3)
.addComponent(poga4))
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.LEADING)
.addComponent(scrollPane1)
.addComponent(scrollPane2)
.addComponent(scrollPane3)
.addComponent(scrollPane4))
);
// Vertically, we want to align each label with his textfield
// on the baseline of the components
layout.setVerticalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
.addComponent(poga1)
.addComponent(scrollPane1))
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
.addComponent(poga2)
.addComponent(scrollPane2))
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
.addComponent(poga3)
.addComponent(scrollPane3))
.addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
.addComponent(poga4)
.addComponent(scrollPane4))
);
