Here is my code:
final JTextArea textArea = new JTextArea();
textArea.setFont(new Font("MS UI Gothic", Font.PLAIN, 13));
textArea.setLineWrap(true);
textArea.setBounds(77, 310, 474, 136);
//contentPane.add(textArea); (edited...still the same problem persists..)
JScrollPane sbrText = new JScrollPane(textArea);
sbrText.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
contentPane.add(sbrText);
When ever I try with this,the text area is not visible..(I am using Eclipse's Window Builder plugin and layout as "Absolute Layout")..
Here I have done, the same thingy using Nested Layout, have a look at the code example :

OUTPUT :
I don't think you need to do contentPane.add(textArea);. It is this line that is causing the problem. Comment out this and your code should work fine.
See this answer, it might help you.
The following code runs fine at my place :
final JTextArea textArea = new JTextArea();
textArea.setFont(new Font("MS UI Gothic", Font.PLAIN, 13));
textArea.setLineWrap(true);
textArea.setBounds(77, 310, 474, 136);
JScrollPane sbrText = new JScrollPane(textArea);
sbrText.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
frame.getContentPane().add(sbrText);//contentPane.add(sbrText);
frame.setVisible(true);
If your code is not running fine then you must have some other error probably related to your contentpane.
Ok...I finally got it to work...I specified the same set bounds in the scroll pane instead of the text area.. Here is the code.!!! ^_^
final JTextArea textArea = new JTextArea();
textArea.setFont(new Font("MS UI Gothic", Font.PLAIN, 13));
textArea.setLineWrap(true);
//textArea.setBounds(77, 310, 474, 136);
JScrollPane scroll = new JScrollPane (textArea, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
scroll.setBounds(77, 310, 474, 136);
contentPane.add(scroll);

Below is a picture of the basic interface I want created. Everything works fine except for the following:-
The JScrollPane isn't appearing when I try inserting lots of text
in the InformationDisplay JTextArea and I don't get why
The buttons I inserted in the unitButtonPanel in the availableUnits JTextArea isn't appearing at all
This is the part in my code that tackles point #1
InfoPanel with informationDisplay TextArea and JScrollPane
JPanel infoPanel = new JPanel();
infoPanel.setLayout(new BorderLayout());
JTextArea informationDisplay= new JTextArea();
JScrollPane scrollbar1 = new JScrollPane(informationDisplay, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

informationDisplay.setFont(new Font(Font.MONOSPACED, Font.PLAIN, 20));
informationDisplay.setText("The \n" + "It\n "+ "The\n" +"A\n" + "About\n" + "\n" + "Cats\n" + "Cats\n" + "Cats\n" + "Cats\n");
informationDisplay.setPreferredSize(new Dimension(getWidth(), 200));
infoPanel.add(scrollbar1);
add(infoPanel, BorderLayout.SOUTH);
This is the part in my code that tackles point #2
Adding a textPanel 3 rows, 1 column to encapsulate 3 TextAreas
JPanel textPanel = new JPanel();
textPanel.setLayout(new GridLayout(3, 1, 4, 4));

I want to add a JButton (panButton) in the lower area of this GUI, but I don’t know to which element I have to add it. I tried to do panButton.add(element) with several elements but nothing works.
I can't understand what is the main element of the panel.
This is how the GUI appears:
While this is the code:

pack();

}
I’d like it appears in the Stato area on the right, or under the Dettagli area.
Can anyone help me?
panButton is a JPanel which is never added to the GUI so if you add something to it, it -also- wont be added to the visible GUI.
You need to add the button to the button panel and add the button panel to the contentPane
JPanel panButton = new JPanel(new BorderLayout());
panButton.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createTitledBorder(" "), BorderFactory.createEmptyBorder(5, 5, 5, 5)));
panButton.add(element); //Add button to panel
...
contentPane.add(panUpper, BorderLayout.NORTH);
contentPane.add(panDetails, BorderLayout.CENTER);
contentPane.add(panButton, BorderLayout.CENTER); //Add panel to contentPane (which I assume is added to the frame at some point as I can see it's elements on the UI you posted)
or just add it the 'Stato' area with panCopy.add(element);
Finally I created a new JPanel and I added the button there.
I am having trouble adding a scroll pane to a nested panel. Here is what I have:
public class board {
public static void addComponentsToPane(Container pane) {
pane.setLayout(new GridLayout(1, 0));
JPanel left = new JPanel();
pane.add(left);
left.setLayout(new BoxLayout(left, BoxLayout.Y_AXIS));
JPanel leftTop = new JPanel();
leftTop.setPreferredSize(new Dimension(266, 300));
leftTop.setBackground(Color.black);
left.add(leftTop);
JScrollPane scrollPane = new JScrollPane(leftTop); //problem is here
left.add(scrollPane);
JButton jb = new JButton();
jb.setPreferredSize(new Dimension(250,50));
leftTop.add(jb);
JButton jb1 = new JButton();
jb1.setPreferredSize(new Dimension(250,50));
leftTop.add(jb1);
JButton jb2 = new JButton();
jb2.setPreferredSize(new Dimension(250,50));
leftTop.add(jb2);
JButton jb3 = new JButton();
jb3.setPreferredSize(new Dimension(250,50));
leftTop.add(jb3);
JButton jb4 = new JButton();
jb4.setPreferredSize(new Dimension(250,50));
leftTop.add(jb4);
JButton jb5 = new JButton();
jb5.setPreferredSize(new Dimension(250,50));
leftTop.add(jb5);
JButton jb6 = new JButton();
jb6.setPreferredSize(new Dimension(250,50));
leftTop.add(jb6);
JPanel leftBottom = new JPanel();
leftBottom.setPreferredSize(new Dimension(266, 300));
leftBottom.setBackground(Color.red);
left.add(leftBottom);
JPanel middle = new JPanel();
pane.add(middle);
middle.setLayout(new BoxLayout(middle, BoxLayout.Y_AXIS));
JPanel middleTop = new JPanel();
middleTop.setPreferredSize(new Dimension(266, 200));
middleTop.setBackground(Color.green);
middle.add(middleTop);
JPanel middleBottom = new JPanel();
middleBottom.setPreferredSize(new Dimension(266, 400));
middleBottom.setBackground(Color.yellow);
middle.add(middleBottom);
JPanel right = new JPanel();
right.setPreferredSize(new Dimension(266, 600));
right.setBackground(Color.blue);
pane.add(right);
}
private static void createAndShowGUI() {
JFrame frame = new JFrame("GridBagLayoutDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
addComponentsToPane(frame.getContentPane());
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
createAndShowGUI();
}
});
}
}
I am just messing around with JPanels and I cannot seem to add scrolling to the left top pane. I think i initialized scrollPane right, but am I adding it to the wrong pane?
Your initial problem is here
leftTop.setPreferredSize(new Dimension(266, 300));
This is overriding what the layout manager (FlowLayout in this case) would otherwise provide to the JScrollPane in order for it to know how to manage the view (when to show the scrollbars for instance)
The next problem you will have is, FlowLayout won't do what you want it to. Instead you might want to use GridLayout or maybe GridBagLayout instead
JPanel leftTop = new JPanel(new GridBagLayout());
//leftTop.setPreferredSize(new Dimension(266, 300));
leftTop.setBackground(Color.black);
JScrollPane scrollPane = new JScrollPane(leftTop); //problem is here
left.add(scrollPane);
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.weightx = 1;
gbc.insets = new Insets(5, 10, 5, 10);
JButton jb = new JButton();
jb.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb, gbc);
JButton jb1 = new JButton();
jb1.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb1, gbc);
JButton jb2 = new JButton();
jb2.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb2, gbc);
JButton jb3 = new JButton();
jb3.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb3, gbc);
JButton jb4 = new JButton();
jb4.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb4, gbc);
JButton jb5 = new JButton();
jb5.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb5, gbc);
JButton jb6 = new JButton();
jb6.setPreferredSize(new Dimension(250, 50));
leftTop.add(jb6, gbc);
Know, if that's not meeting your needs, you will need to create a custom component which implements Scrollable, which will allow you to specify PreferredScrollableViewportSize which will tell the JScrollPane what the preferred size of the viewable area should be, rather then using the preferredSize of the view
Can you please tell me why the scroll doesn't work. It is visible, but it doesn't work,
here you can view that piece of code. What could be the missing part?
// GUI elements
private JTextField textSend = new JTextField(20);
private JTextArea textArea = new JTextArea(5, 20);
private JScrollPane scroll = new JScrollPane(textArea);
private JButton buttonConnect = new JButton("Connect");
private JButton buttonSend = new JButton("Send");
private JButton buttonDisconnect = new JButton("Disconnect");
private JButton buttonQuit = new JButton("Quit");
private JPanel leftPanel = new JPanel();
private JPanel rightPanel = new JPanel();
private JLabel empty = new JLabel("");
ChessHeroChatClient() {
setTitle("ChessHero Chat Client");
setLocationRelativeTo(null);
setSize(500, 500);
setResizable(false);
leftPanel.setLayout(new BorderLayout());
rightPanel.setLayout(new GridLayout(6, 1));
scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
leftPanel.add(textSend, BorderLayout.NORTH);
leftPanel.add(textArea, BorderLayout.WEST);
leftPanel.add(scroll, BorderLayout.EAST);
add(leftPanel, BorderLayout.CENTER);
add(rightPanel, BorderLayout.EAST);
textArea.setEditable(false);
private JTextArea textArea = new JTextArea(5, 20);
private JScrollPane scroll = new JScrollPane(textArea);
You create the scrollPane with the textArea which is good.
//leftPanel.add(textArea, BorderLayout.WEST); // this is wrong
leftPanel.add(scroll, BorderLayout.EAST);
But then you add the textArea to the WEST and the scroll to the EAST, which is wrong. A Swing component can only have a single parent, so just leave the textArea alone and add the scrollPane to the EAST or WEST.
How can I get rid of that gray box?
This is what I'm talking about:
i would really appreciate if you could help me out

JLabel background = new JLabel(new ImageIcon("background.png"));
add(background);
The default layout manager for a JFrame is a BorderLayout. When you add a component without specifying a constraint the component is added to the CENTER. You can't add multiple components to a single location.
Instead you need to use a different component as the background. Then you add your panel to this component. Check out Background Panel. Then code would be something like:
Background background = new BackgroundPanel(...);
background.add(panel);
add(background);
setResizable(false);
pack();
