GUI won't display two seperate scrollpanes - java

As you can see in my code, there are two scroll panes at the bottom. I need my gui to show both of these scroll panes on the right side, the smaller one(displaying the current amount of money the player has, this one I need to stay one line thick) and the second one, which will be constantly spitting out information of the player's rolls on the bottom.
Also how do I make it so that my combo box listener will give every item a 10 to its output to start out with then when it is being sent out it gives each 1 more so that they have their unique number starting at 11 then 12, 13, and so on.

Two things...
One, if you've added the same scroll pane twice...
JScrollPane scrollPane = new JScrollPane();
contentPane.add(scrollPane, BorderLayout.CENTER);
JScrollPane scrollPanel = new JScrollPane();//This will hold the information the bot sends over such as win/loose or error
contentPane.add(scrollPane, BorderLayout.CENTER);
^--- Note no "l"
And, even if you have added the two scroll pane instances, you've added them to the same place, BorderLayout.CENTER
BorderLayout only allows a single component to be added to one of the available positions it supports, so, in this case, only the second scroll pane would be visible

Java Swing GridBagLayout JTextField Changing size after adding error message

I have been chasing this bug for awhile and can't seem to figure it out. I have a small GUI with a list of labels and text fields. In between the rows that have a label + text field, there is an empty row that contains a JLabel to populate with an error message as necessary. The issue is, when this error message populates, the text fields above them are compressed for some reason and after a few hours of trying different things, I can't seem to pinpoint why. It also seems like all the labels/text areas compress compared to each other slightly as well. Can anyone point out the issue?
I have tried giving each element more space as well in the panel gridbaglayout. That doesn't seem to change the end result.
If looking at the code, the elements are on the 'continuousTransferPanel" Also the "singleTransferPanel" has the same issue with only 2 rows.

Resulting GUI:

Since the problem is with your JTextField's Border, and since you can't reset the default border outright without running into problems, one solution is to create a CompoundBorder for your JTextField, the outer border a LineBorder that uses the same color as the JPanel's background color and the inner border being JTextField's default border. Then in your action listener, simply create a new compound border, one that uses a Color.RED outer border.
So when creating my JTextFields in the example below, I also create a CompoundBorder, giving it an outerBorder and innerBorder like so:
// create JTextField with TF_COLS int column count value
JTextField textField = new JTextField(TF_COLS);
// get the JTextField's default border and make it our inner border
Border innerBorder = textField.getBorder();
// create an outer LineBorder that uses the JPanel's background color
Border outerBorder = BorderFactory.createLineBorder(BACKGROUND);
// create the compound border with these two borders
CompoundBorder myBorder = BorderFactory.createCompoundBorder(outerBorder, innerBorder);
// and set the JTextField's border with it
textField.setBorder(myBorder);
Then in the JButton's ActionListener, get the JTextField's current border, our compound border, and change the outer border's line color. Simple:
// loop through all the JLabel texts
for (int i = 0; i < LABELS.length; i++) {
String text = LABELS[i]; // get the array item
// use it to get the JTextField associated with this String
JTextField textField = labelFieldMap.get(text);
// same for the error JLabel
JLabel errorLabel = errorLabelMap.get(text);
// get our current JTextField's border which is a compound border
CompoundBorder myBorder = (CompoundBorder) textField.getBorder();
// the insideBorder, the original JTextField's border, will be unchanged
Border insideBorder = myBorder.getInsideBorder();
// if the text field is empty (and not the last jtext field)
if (i < LABELS.length - 1 && textField.getText().trim().isEmpty()) {
errorLabel.setText(ERROR_MESSAGE); // set the error JLabel
// set txt field's color if we want
textField.setBackground(ERROR_BG_COLOR);
// okToTransfer = false;
// create a compound border, the outer border now a line border, RED
Border outsideBorder = BorderFactory.createLineBorder(Color.RED);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder, insideBorder);
// set the JTextField's border to this one
textField.setBorder(newBorder);
} else {
// else all OK
errorLabel.setText(" ");
textField.setBackground(Color.WHITE);
// set the JTextField's border back to our original compound border
Border outsideBorder = BorderFactory.createLineBorder(BACKGROUND);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder,
insideBorder);
textField.setBorder(newBorder);
}
System.out.println(text + " " + textField.getText());

Componenets alignment in GridBagLayout

I am using GridBagLayout to align components. Actually, i have two buttons which i want to align like this:
Desired layout:
But the following code results in the following layout:
Resulted layout:
My code:
iconAdd = new ImageIcon(getClass().getResource("../images/add.png"));
add = new JButton(iconAdd);
add.setPreferredSize(new Dimension(130, 100));
add.setBorder(new LineBorder(Color.decode("#9b9999"), 1, true));
add.setCursor(Cursor.getPredefinedCursor(12));
gbc.gridx = 0;
gbc.gridy = 0;
gbc.weightx = 1;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(5, 5, 5, 5);
pane.add(add, gbc);
iconSearch = new
ImageIcon(getClass().getResource("../images/search.png"));
search = new JButton(iconSearch);
search.setCursor(Cursor.getPredefinedCursor(12));
search.setPreferredSize(new Dimension(130, 100));
search.setBorder(new LineBorder(Color.decode("#9b9999"), 1, true));
gbc.gridx++;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(5, 5, 5, 5);
pane.add(search, gbc);
Any help would be highly appreciated.

You are telling the layout to give extra space to each component. So essentially each component becomes half the size of the frame.
You really only want that constraint set for the second button, so it takes up all the remaining space.
Read the section from the Swing tutorial on How to Use GridBagLayout which explains how the weightx/y constraints should be used.
Also, an easier solution would be do just use a FlowLayout. Create a panel with a FlowLayout. Add the buttons to the panel. Then add the panel to the BorderLayout.PAGE_START of the frame.

How to make GUI using Java Swing

So I recently started learning object-oriented programming, did most basic stuff in Java and now I want to change from console writing to actual GUI.
But I have problem understanding how it works, I read everything in oracle documentation but their examples are not so clear and easy to understand, also googled it but couldn't manage to find any good explanation. This is my last resort.
Here is my idea of how my program GUI should look:
![like this][1]
I couldn't draw very nice but all check boxes should be aligned.
If someone can provide me explanation with code that would be great, if not just some good explanation would help me a lot, my problem is that when I align 1 thing other gets messed up.
My current code:
public class Zadatak2 extends JFrame{
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
new Zadatak2();
}
public Zadatak2(){
JPanel panel1 = new JPanel();
setSize(500, 250);
setLocationRelativeTo(null);
add(panel1);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
BorderLayout border1 = new BorderLayout();
panel1.setLayout(border1);
JPanel panel2 = new JPanel();
GridLayout grid1 = new GridLayout(3,2);
panel2.setLayout(grid1);
panel2.add(new JCheckBox("Bold"));
panel2.add(new JCheckBox("Italic"));
panel2.add(new JCheckBox("Underline"));
panel1.add(panel2,BorderLayout.WEST);
JPanel panel3 = new JPanel();
GridLayout grid2 = new GridLayout(4,1);
panel3.setLayout(grid2);
panel3.add(new JCheckBox("Strikerthrough"));
panel3.add(new JCheckBox("Teletype"));
panel3.add(new JCheckBox("Emphasis"));
panel3.add(new JCheckBox("Strong"));
panel1.add(panel3,BorderLayout.CENTER);
JPanel panel4 = new JPanel();
BorderLayout border2 = new BorderLayout();
panel4.setLayout(border2);
panel4.add(new JButton("Apply"), BorderLayout.EAST);
panel4.setBorder(BorderFactory.createEmptyBorder(0, 0, 10, 70));
panel1.add(panel4,BorderLayout.SOUTH);
JPanel panel5 = new JPanel();
GridLayout grid3 = new GridLayout(2,1);
panel5.setLayout(grid3);
panel5.add(new JLabel("Sample text"));
JTextArea ta = new JTextArea("Sample text");
panel5.setBorder(BorderFactory.createEmptyBorder(5, 0, 10, 30));
ta.setSize(200, 200);
panel5.add(ta);
panel1.add(panel5,BorderLayout.EAST);
setVisible(true);
}
}
Thanks for help from everyone, finally made the gui right, now I understand thins much better.

To position the check boxes in the GridLayout, you should not define a panel for each column. Just define and place them like this:
JPanel panel2 = new JPanel();
GridLayout grid1 = new GridLayout(4, 2);
panel2.setLayout(grid1);
panel2.add(new JCheckBox("Bold"));
panel2.add(new JCheckBox("Strikerthrough"));
panel2.add(new JCheckBox("Italic"));
panel2.add(new JCheckBox("Teletype"));
panel2.add(new JCheckBox("Underline"));
panel2.add(new JCheckBox("Emphasis"));
panel2.add(new JLabel("")); // fill the empty cell with an empty label
panel2.add(new JCheckBox("Strong"));
However, since you have a TextArea that should be aligned with the check boxes and span several rows, I would recomment using a GridBagLayout instead. It's more code to write, but much more flexible than the GridLayout.
An example:
public Zadatak2() {
JPanel panel1 = new JPanel();
setSize(500, 250);
setLocationRelativeTo(null);
add(panel1);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
BorderLayout border1 = new BorderLayout();
panel1.setLayout(border1);
JPanel panel2 = new JPanel();
GridBagLayout grid1 = new GridBagLayout();
panel2.setLayout(grid1);
panel2.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
Insets insets = new Insets(2, 2, 2, 2);
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 0;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Bold"), c);
c = new GridBagConstraints();
c.gridx = 1;
c.gridy = 0;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Strikerthrough"), c);
c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 1;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Italic"), c);
c = new GridBagConstraints();
c.gridx = 1;
c.gridy = 1;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Teletype"), c);
c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 2;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Underline"), c);
c = new GridBagConstraints();
c.gridx = 1;
c.gridy = 2;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Emphasis"), c);
c = new GridBagConstraints();
c.gridx = 1;
c.gridy = 3;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JCheckBox("Strong"), c);
insets = new Insets(2, 40, 2, 2);
c = new GridBagConstraints();
c.gridx = 2;
c.gridy = 0;
c.insets = insets;
c.anchor = GridBagConstraints.WEST;
panel2.add(new JLabel("Sample text"), c);
c = new GridBagConstraints();
c.gridx = 2;
c.gridy = 1;
c.insets = insets;
c.weightx = .5;
c.fill = GridBagConstraints.BOTH;
c.gridheight = 3;
JTextArea ta = new JTextArea("Sample text", 4, 4);
JScrollPane sp = new JScrollPane(ta);
panel2.add(sp, c);
c = new GridBagConstraints();
c.gridx = 2;
c.gridy = 5;
c.insets = new Insets(40, 40, 2,2);
c.anchor = GridBagConstraints.WEST;
panel2.add(new JButton("Apply"), c);
panel1.add(panel2, BorderLayout.CENTER);
pack();
setVisible(true);
}
The result:
Please see the GridBagLayout Tutorial and the JavaDoc to learn about all the options of this layout.

Remember to nest JPanels each using its own layout. For instance your imaged GUI could be made one of many ways. The overall JPanel could use BoxLayout oriented to the line, and on the left have a GridLayout using JPanel on the right a BorderLayout using JPanel. For example:
Other issues:
The JTextArea should be placed into a JScrollPane, and the scrollpane then added to the GUI.
NEVER set the sizes or preferred sizes of text components, especially JTextAreas as that will prevent them from working correctly, especially if within a scrollpane.
Instead set the JTextArea's column and row properties.
Avoid setting sizes in general. Let the GUI components and layouts set their own sizes by calling pack() on the JFrame after adding everything and before setting it visible.
For example, with slight modification:
import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.GridLayout;
import javax.swing.*;

Unable to add make JTextArea show multiplie lines insidea JScrollPane

I am trying to make multiple lines of a JTextArea visible.I am using GridBagLayout to add the components. Here is a code snippet:
import javax.swing.*;
import javax.swing.border.BevelBorder;
import java.awt.*;
public class SSCE {
SSCE(){
JFrame f1=new JFrame();
GridBagLayout gbl=new GridBagLayout();
JButton btnAddAcc=new JButton("Add Acount");
JButton insertId=new JButton("Insert");
JButton insertTweet=new JButton("Insert2");
JButton tweetButton=new JButton("TweetButton");
JLabel accountStatusHeader=new JLabel("account status Header");
JLabel accountDisplayNameHeader=new JLabel("account displayname Header");
JLabel enterInterval=new JLabel("enter Interval!!");
final JTextArea accountDispName = new JTextArea(50, 50);
final JTextArea statusDisplay = new JTextArea(50, 50);
final JTextArea jTextAreaId = new JTextArea(20, 50);
final JTextArea jTextAreaTweets = new JTextArea(20, 50);
jTextAreaId.setBorder(BorderFactory.createBevelBorder(BevelBorder.RAISED,
Color.PINK, Color.GREEN));
final JTextArea tweetLog = new JTextArea(100, 100);
tweetLog.setPreferredSize(new Dimension(1000, 5000));
JScrollPane tweetLogPaneScroll = new JScrollPane(tweetLog);
JScrollPane idScrollPane = new JScrollPane(jTextAreaId);
JScrollPane tweetScrollPane = new JScrollPane(jTextAreaTweets);
final JTextField timeIntervalInput = new JTextField(20);
final JTextField tagIdInsertTextBox = new JTextField(50);
final JTextField tweetInsertTextBox = new JTextField(50);
f1.setLayout(gbl);
f1.add(btnAddAcc,makeGbc(0,0,1,2));
f1.add(accountDisplayNameHeader,makeGbc(1,0));
f1.add(accountStatusHeader,makeGbc(1,1));
f1.add(accountDispName,makeGbc(2,0));
f1.add(statusDisplay,makeGbc(2,1));
f1.add(enterInterval,makeGbc(3,0));
f1.add(timeIntervalInput,makeGbc(3,1));
f1.add(new JLabel("Twitter Ids"),makeGbc(4,0));
f1.add(new JLabel("Tweets"),makeGbc(4,1));
f1.add(idScrollPane,makeGbc(5,0,5));
f1.add(tweetScrollPane,makeGbc(5,1,5));
f1.add(tagIdInsertTextBox,makeGbc(10,0));
f1.add(tweetInsertTextBox,makeGbc(10,1));
f1.add(insertId,makeGbc(11,0));
f1.add(insertTweet,makeGbc(11,1));
f1.add(tweetButton,makeGbc(12,0,1,2));
f1.add(tweetLogPaneScroll,makeGbc(13,0,6,2));
f1.setSize(800,400);
f1.setVisible(true);
f1.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
accountDispName.setVisible(false);
statusDisplay.setVisible(false);
}
private GridBagConstraints makeGbc(int y, int x) {
GridBagConstraints gbc = new GridBagConstraints();
// gbc.gridwidth = 1;
// gbc.gridheight = 1;
gbc.gridx = x;
gbc.gridy = y;
gbc.weightx = 1.0;
gbc.weighty = 1.0;
gbc.insets = new Insets(2, 2, 2, 2);
gbc.anchor = (y == 0) ? GridBagConstraints.LINE_START : GridBagConstraints.LINE_END;
gbc.fill = GridBagConstraints.BOTH;
return gbc;
}
private GridBagConstraints makeGbc(int y, int x,int gridheight) {
GridBagConstraints gbc = new GridBagConstraints();
// gbc.gridwidth = 1;
gbc.gridheight = gridheight;
gbc.gridx = x;
gbc.gridy = y;
gbc.weightx = 1.0;
gbc.weighty = 1.0;
gbc.insets = new Insets(2, 2, 2, 2);
gbc.anchor = (y == 0) ? GridBagConstraints.LINE_START : GridBagConstraints.LINE_END;
gbc.fill = GridBagConstraints.BOTH;
return gbc;
}
private GridBagConstraints makeGbc(int y, int x,int gridheight,int gridwidth) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = gridwidth;
gbc.gridheight = gridheight;
gbc.gridx = x;
gbc.gridy = y;
gbc.insets = new Insets(2, 2, 2, 2);
gbc.anchor = (y == 0) ? GridBagConstraints.LINE_START : GridBagConstraints.LINE_END;
gbc.fill = GridBagConstraints.BOTH;
return gbc;
}
public static void main(String args[]){
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
SSCE a1;
a1 = new SSCE();
}
});
}
}
Please note the following lines:
f1.add(idScrollPane,makeGbc(5,0,5));
f1.add(tweetScrollPane,makeGbc(5,1,5));
In above, I am passing the third paramenter(the gridheight) as 5 but still I see only one row. I want to set the row span to 5.
And Also the following:
f1.add(tweetLogPaneScroll,makeGbc(13,0,6,2));
Here again, I am passing the third param(gridheight) as 6.But yet I see only one Row of textarea. So what is going wrong?? And whats the solution?

Your SSCCE helps me to see everything -- thanks! I've voted to open your question and have up-voted it. You're killing yourself with your unrealistic JTextArea row numbers, and then setting the size of your GUI. Get rid of all setSize(...) and setPreferredSize(...) method calls. Make your JTextArea row counts 5 or 10, not 50, not 100. Call pack() before setVisible(true).
For example, please see the changes I've made below as well as comments with !! in them. Note that I've tried to get rid of most of your magic numbers, but you still need to do the same with the column counts. I've also added text to your text components for the sake of debugging, so that I can see at a glance which text component goes with which variable. You'll of course not want to have this text present in the presentation code, but again, it's a useful debugging tool:

System.out.printf("gridwidth, gridheight: [%d, %d]%n", gbc.gridwidth,
gbc.gridheight);
return gbc;
}
private GridBagConstraints makeGbc(int y, int x, int gridheight) {
GridBagConstraints gbc = new GridBagConstraints();
// gbc.gridwidth = 1;
gbc.gridheight = gridheight;
gbc.gridx = x;
gbc.gridy = y;

gbc.insets = new Insets(2, 2, 2, 2);
gbc.anchor = (y == 0) ? GridBagConstraints.LINE_START

return gbc;
}
private GridBagConstraints makeGbc(int y, int x, int gridheight,
int gridwidth) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = gridwidth;
gbc.gridheight = gridheight;

}
public static void main(String args[]) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
SSCE a1;
a1 = new SSCE();
}
});
}
}
This results in a GUI that looks like so:
Note, I would also change the GridBagConstraints for JTextFields from BOTH to HORIZONTAL.
Edit
You state in comment:
One more question if u dont mind answering.the TimeIntervalInput is appearing so wide although I have defined it to hold at max 20 chars.Any solution to that?
You need to continue to play with your grid bag constraints as the ones you're using are quite restrictive. For example, note what happens when I use more exacting constraints on the GBC for that JTextField:
GridBagConstraints gbc = makeGbc(3, 1);
gbc.fill = GridBagConstraints.NONE;
gbc.anchor = GridBagConstraints.WEST;
f1.add(timeIntervalInput, gbc);
