Adding JButton in JList

Hi
I wonder if it is possible to add JButton in a JList? Or how can I produce a list of JButtons? Each button represents a person (an object), is there anyway to add listener to the buttons so i can get the person thats represnted by the button? I can decide in advance how many button ther will be...that depends on the number of person in the db.

Use a panel with a GridLayout. The Panel can be added to a JScrollPane. Read this section on "Layout Managers":

Adding JButton, JTextField to scroll pane...

I have developed an appln in which I have added JPanel to JFrame.
To this JPanel I m adding JButton & JTextField. But the JButton & JTextField are increasing dynamically in my appln[according to DBMS query]. So I wanted to use scrolpane or something like so that the window can be scrolled vertically to view all the components[JButton & JTextField]. I m developing this as a standalone appln.
Plz help..
Thanking in advance.

Thanx fouadk ,
But my problem still persists. Now though I m able to add JPanel to JScrollPane, but when the components in the JPanel increase than the height of the Pane, the components at the dowm are not visible unless I resize the window by manually dragging the corners. Actually I wanted to keep the size of the window constant and make use of the VERTICAL SCROLLBAR.
Plz help.
Thanking in advance.
Following is code:
import javax.swing.*;
public class testt extends JFrame {
private JPanel p = new JPanel();
private JScrollPane sp = new JScrollPane(p
,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS
,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
private JButton b[] = new JButton[15];
public testt() {
super("TEST");
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(500, 400);
setLocation(50, 20);
this.add(sp);
p.setLayout(null);
sp.setAutoscrolls(true);
for(int i = 0, y = 10; i < 15; i++, y += 40)
     b[i] = new JButton("BUTTON "+ (i+1));
     b.setBounds(10,y,100,20);
     p.add(b[i]);

Adding JButtons to a Java2d Graphics program

Hi,
I apologise to all you seasoned programmers if this seems an easy question, but I can't seem to see the solution to this one.
I'm trying to add 2 JButtons to an existing Java2D graphics program. When I run the program I get the following error,

Your public class extends JFrame so it is a JFrame. In your main method you create a new JFrame and try to add the enclosing class (a JFrame by extension) to it. So you can either:
1 — remove the JFrame extension from the class declaration and leave the code in the main method as—is:
public class PM2C implements ActionListener {or,
2 — leave the JFrame extension and remove the new JFrame instance in the main method.
public class PM2C extends JFrame implements ActionListener {
    public PM2C(String title) {
        super(title);
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
        Container contentPane = getContentPane();
        JPanel panel = new JPanel();
        leftButton = new JButton("Leftt");
        leftButton.addActionListener(this);
        panel.add(leftButton);
        rightButton = new JButton("Right");
        rightButton.addActionListener(this);
        panel.add(rightButton);
        contentPane.add(panel, BorderLayout.SOUTH);
        setSize(600, 600);

How can I add several JButton into JList?

I want to add several button into a Jlist. I tried this method, list.add(button,1),nothing shows up.I am not sure whether jList has the function.If it is,please show me how to achieve that.Thanks in advance!

A JList is used to display text Strings. You should be able to add a JButton to the JList but all you will see is the toString() representation of the JButton. You will not see a button or be able to click on it.
Try creating a panel using a GridLayout with a single column and add all you JButtons to the panel.

Adding JButtons to JTable

Hello all,
How can I add JButtons to a JTable?
I found an article that is supposed to show you how to do just that:
http://www.devx.com/getHelpOn/10MinuteSolution/20425
I downloaded the code in the article and it works to an extent - I can see the buttons in the table but the buttons seem as if they are disabled :( Since I used this code in my application, I get the same behavior too.
Is there a bug in the code? Is there a simpler solution? What am I missing?
Raj

Thanks. That makes the button clickable. But now the button changes back to it's old value when you click on another cell. I suppose that's because we have 2 buttons, one for rendering and one for editing. So I added a setValueAt(Object value, int row, int column) to MyModel. This works throws class cast exception.

Problems adding to a JList

in my filter panel i have a text field, and a search button. when i enter some text and click search, the text should appear in the JList. but all that happens is the test field clears (which should happen) but doesnt appear in the JList. here is my code below:
firstly for the setting up of the JList:
          //the JList with a model, renderer and selectionListener
          filterListModel = new DefaultListModel();
          filterList = new JList(filterListModel);
          filterList.setCellRenderer(new CustomCellRenderer());
          filterList.addListSelectionListener(new MyListSelectionListener());
          filterList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);then the action performed for the search button
               public void actionPerformed(ActionEvent e) {
                    if (textFilter.getText().equals("")) {
                         JOptionPane.showMessageDialog(null, "No keyword has been entered");
                    } else {
                         int index = filterList.getSelectedIndex(); //get selected index
                         if (index == -1) { //no selection, so insert at beginning
                              index = 0;
                         } else { //add after the selected item
                              index++;
                         filterListModel.insertElementAt(textFilter.getText(), index);
                         //Reset the text field.
                         textFilter.requestFocusInWindow();
                         textFilter.setText("");
                         //Select the new item and make it visible.
                         filterList.setSelectedIndex(index);
                         filterList.ensureIndexIsVisible(index);
               }i also wanted to be able to detect selected items and display them as cyan in color. i have created 2 inner classes for this.
class MyListSelectionListener implements ListSelectionListener {
     public void valueChanged(ListSelectionEvent e) {
          if (e.getValueIsAdjusting() == false) {
               if (filterList.getSelectedIndex() == -1) {
                    //No selection, disable fire button.
                    removeFilter.setEnabled(false);
               } else {
                    //Selection, enable the fire button.
                    removeFilter.setEnabled(true);
} //end class MyListSelectionListener
class CustomCellRenderer extends JLabel implements ListCellRenderer {
     public Component getListCellRendererComponent(JList list, // the list being redrawn
     Object value, // value to display
     int index, // cell index
     boolean isSelected, // is the cell selected
     boolean cellHasFocus) // the list and the cell have
     // the focus
     { //begin getListCellRendererComponent() body
          if (isSelected) { //set the background for selected
               setBackground(Color.cyan);
          } else { //set the background for not selected
               setBackground(Color.white);
          } //end else
          return this; //return component used to render
     } //end getListCellRendererComponent()
} //end class CustomCellRenderer any help is much appreciated

when i enter some text and click search, the text should appear in the JListThe section in the Swing tutorial on "How to Use Lists" has an example almost exactly like this:
http://java.sun.com/docs/books/tutorial/uiswing/components/list.html
i also wanted to be able to detect selected items and display them as cyan in color.It is generally better to extend the DefaultListCellRenderer (it extends JLabel) as some methods have been optimized for painting efficiency.
I don't know if this is your problem, but whenever you extend JLabel directly you need to use
setOpaque( true );
otherwise the background color is inherited from the parent component.

Adding JButton in a JTable

hi
i know this has been discussed quite a number of times before, but i still couldn't figure it out..
basically i just want to add a button to the 5th column of every row which has data in it.
this is how i create my table (partially)
     private JTable clientTable;
     private DefaultTableModel clientTableModel;
private JScrollPane scrollTable;
clientTableModel = new DefaultTableModel(columnNames,100);
          clientTable = new JTable(clientTableModel);
          TableColumn tblColumn1 = clientTable.getColumn("Request ID");
          tblColumn1.setPreferredWidth(70);
          tblColumn1 = clientTable.getColumn("Given Name");
          tblColumn1.setPreferredWidth(300);
          tblColumn1 = clientTable.getColumn("Address");
          tblColumn1.setPreferredWidth(350);
          tblColumn1 = clientTable.getColumn("Card Serial");
          tblColumn1.setPreferredWidth(100);
          tblColumn1 = clientTable.getColumn("Print Count");
          tblColumn1.setPreferredWidth(70);
          tblColumn1 = clientTable.getColumn("Print?");
          tblColumn1.setPreferredWidth(40);
          clientTableModel.insertRow(0,data);
          //clientTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
          scrollTable = new JScrollPane(clientTable);and i call this function void listInfoInTable(){
          JButton cmdPrint[];
          Vector columnNames = new Vector();
          Object[] data={"","","","","",""};

//                  modelCol.getColumn(5).setCellRenderer();
                  clientTableModel.insertRow(j,data);
                  j++;
          }catch (SQLException ex){
               JOptionPane.showMessageDialog(null,"Database error: " + ex.getMessage());
     } to display data from database inside the table.
How do I add JButton to the 5th column of each row? This documentation here http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#width says that i need to implement TableCellEditor to put JButton in the table. How do i really do it? I want the button to call another function which prints the data from the row (but this is another story).
Any help is greatly appreciated. Thanks

you would need CellRenderer i think that it is in
javax.swing.table.*;
see if you can get started with that.
Davidthanks, i'll try and have a look at it
Yes, that's definitely what you need to start with,
but you also need a CellEditor to return the
button as well, otherwise the button will not be
clickable (the renderer just paints the cell for
display, it doesn't allow you to interact with it).
You could maintain a list of components for rendering
each cell of the table so that your
CellRenderer and CellEditor always
return the same object (i.e. a JButton for any
given cell).
CB.thanks for the info.. could you point me to some examples? is sounds quite complicated for me....
thanks again

Adding files to jlist

hi,
i trying to add File objects to a JList can keep getting a nullpointer exception, here is the code:
private DefaultListModel listModel;
File file = new File("c:");
File[] files = file.listFiles();
addToListModel(files);
fileList = new JList(files);
public void addToListModel(File[] list) {
     System.out.println("lenght is " + list.length);
     System.out.println(list[0]);
     for(int i = 0; i < list.length; i++) {
          listModel.addElement(list);
i put a println in the method, it print 5 as the lenght and does output the first value in the array, but then throws the nullpointer excpetion, any ideas?
Thank you.

Are you sure you created listModel? I don't see
listModel = new DefaultListModel()in your sample? If you didn't it would be null.

Adding Images in JList?

Hi guys,
how do i add Images in JList along with Text? please help me here.
cheers,

You will have to provide some images (place them in the same directory as the compiled class file) for the following example.

        String value;
        Icon image;
    private Icon getIcon(String name)
        java.net.URL url = getClass().getResource(name);
        return new ImageIcon(url);
    public JListExample()
        super("Simple JList Example");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final Value[] VALUES =
            new Value("<html><body>One for<br>      the road", getIcon("Add24.gif")),

Adding JButton in BorderLayout

Hi everyone,
I have a question about Panel. I want to know how can we add 2 button at the bottom of panel2 and then add panel2 into panel1. here is what I did.
     // 2 buttons for panel2
     JButton b1 = new JButton ("Start");
     b1.addActionListener(this);
     JButton b2= new JButton("Stop");
     b2.addActionListener(this);
     panel2.add(b1);

Class1
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class Class1 extends javax.swing.JFrame {
   //////GUI specifications
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new TestTableButton().setVisible(true);
        Class2 model=new Class2();
        jTable1=new JTable(model);
        jScrollPane1.setViewportView(jTable1);
    // Variables declaration - do not modify
    private javax.swing.JScrollPane jScrollPane1;

    public int getColumnCount() {
        return columnNames.length;
    public int getRowCount() {
        return data.length;

        return getValueAt(0, c).getClass();
     * Don't need to implement this method unless your table's
     * editable.
    public boolean isCellEditable(int row, int col) {
        //Note that the data/cell address is constant,
        //no matter where the cell appears onscreen.
            return false;
     * Don't need to implement this method unless your table's
     * data can change.
    public void setValueAt(Object value, int row, int col) {

Adding color to JList

Hello,
I have a Jlist that I would like to color the rows on. Each row I in the Jlist displays
a string, I would like for everyother row to be light blue or something. I have looked at the
api and the only method i see that deals with setting bg color is...
setSelectionBackground(Color selectionBackground)
but I dont think this is what I want. Is this possible...if so could I see a example.
thanks,
jd

Well I was hoping to get this up here before anyone else, but I guess that didn't happen. Here's a sample:
import java.awt.*;
import javax.swing.*;
public class ListTest extends JFrame {
        private JList list;
        public ListTest() {
                getContentPane().setLayout( new FlowLayout() );
                String[] data = { "one", "two", "three", "four", "five" };
                list = new JList( data );
                list.setCellRenderer( new MyCellRenderer() );
                getContentPane().add( list );
                setTitle( "List Test" );
                setSize( 320, 240 );
                setLocationRelativeTo( null );
                setVisible( true );
        public static void main( String[] args ) {
                ListTest application = new ListTest();
                application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
class MyCellRenderer extends JLabel implements ListCellRenderer {
        public MyCellRenderer() {
                setOpaque( true );
        public Component getListCellRendererComponent( JList list, Object object, int index, boolean isSelected, boolean cellHasFocus ) {
                setText( object.toString() );
                if ( isSelected ) {
                        setBackground( Color.BLUE );
                        setForeground( Color.WHITE );
                else {
                        if ( index % 2 == 0 ) {
                                // Even cell
                                setBackground( Color.WHITE );
                                setForeground( Color.BLACK );
                        else {
                                // Odd cell
                                setBackground( Color.LIGHT_GRAY );
                                setForeground( Color.BLACK );
                setEnabled( list.isEnabled() );
                setFont( list.getFont() );
                return this;
}

Probelms Adding items to JList Component

i tried to add items to JList from the database.... and it can add to the variable but the list isnt displaying....
here is my code for that button...
list_ListTopic = new JList(new DefaultListModel());
DefaultListModel listModel = (DefaultListModel)list_ListTopic.getModel();
jScrollPane1 = new JScrollPane(list_ListTopic);
jScrollPane1.setViewportView(list_ListTopic);
Vector data = new Vector();
listModel.clear();
while (lrs.next())
data.add(lrs.getString("tName"));
i++;
list_ListTopic.setListData(data);
jScrollPane1.setViewportView(list_ListTopic);Thanks!

Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/list.html]How to Use Lists. It shows you how to initially load data into a list and then how to add/remove entries from the list. In general, you don't update the Vector after the ListModel has been created you update the model directly.

Adding JButton onto a Rectangle

Hi All,
Is there any way to add a JButton onto the Rectangle..???
I have drawed a rectangle by using Graphics class and i need a button to be embedded onto that.
Thanks in advance.
regards,
Viswanadh

A Rectangle is not a Component so no you can't "add" it to a Rectangle.
Is the Rectangle the same size as the button so only one button fits in the rectangle. Or do you have multiple buttons in the Rectangle.
In the first case you could just add a Border to the button. In the second case you add a Border to a JPanel and then add the buttons to the panel.
I suggestion you start by reading the [Swing tutorial|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html]. Maybe the section on Layout Managers so you learn how to control the positioning of Components in a Container.

Adding JButton to JTextAreas

I'm publishing reports from data onto an uneditable JTextArea (so the user can save it as a text doc if they wish).
I'd like to have a button next to each report so the user can view the data for that report, but presumably this can't be done on a JTextArea?
Anyone have any suggestions as to how I can have a 'View data' button, but still be able to save the text of the report?
Many thanks.

If you are trying to produce a panel that has a JTextArea and a JButton on it, that is relatively easy to do.
You cannot put a JButton into a text area but it is easy enough to put it either next to or below the text area and provide the functionality that you are looking for.
