Using JButtons in a JTable
I'm trying to find some information about how to use a JButton within a cell of a JTable. I'm able to insert the button using a custom cell renderer. Basically I create my own renderer which is triggered for JButton.class. That works well.
Of course I do a addActionListener() on the JButton so something will happen when it is pressed.
But the problem is that events aren't getting through to the button at all. The table is getting all the mouse events and is not passing them on.
I'm sure I'm not the first to run into this. Any suggestions on how to get the events to the button, or otherwise deal with this problem?
Thanks
Those example are from 1998. I don't think they work anymore.
Basically, if I could just find a way to get the JTable to send any kind of event to any class that I can write, I would be happy. That would do the trick.
One possibility is to just use a mouse listener, although that seems like a very low-level way to do something which should be at a higher level. But that seems like the only way. Try as I might, I can't find a way to set an editor for these cells.
I used table.setDefaultEditor(JButton.class, myTableCellEditor), and I tried to set it on the column, too, but myTableCellEditor never gets called in response to events.
Any other approaches?
Thanks

How to use JButton as a JTable column header?
I'd like to use JButtons as my JTable's column headers.
I built a JButton subclass which implemented TableCellRenderer and passed it to one of my table column's setHeaderRender method. The resulting header is a component that looks like a JButton but when clicked, it does not visually depress or fire any ActionEvents.You might want to check this example and use it accordingly for your requirements.
http://www2.gol.com/users/tame/swing/examples/JTableExamples5.html
Reason: The reason you're unable to perform actions on JButton is JTableHeader doesn't relay the mouse events to your JButtons.
I hope this helps.
have fun, ganesh. -
Changing the size of a jbutton inside a jtable
Hi,
I have found this example for adding a jbutton to a jtable:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=715330
however, I have cannot seem to figure out how to set the size of the jbutton. Currently, the jbutton is filled to the size of the cell within the jtable, but i want to have it a bit smaller and centered (the rows of my table are rather large in hieght)
I tried the setSize()
setPrefferedSize()
setMinimumSize()
setMaximumSize()methods, but nothing seems to work. Has anyone been able to do this?Use a JPanel instead of a JButton as cell renderer. Put a button inside the panel - use FlowLayout.

Multiple clicks using JButtons
I am using JButtons to trigger events in an experiment and then logging data using the System.time method.
However I seem to be getting multiple printouts when a button is only clicked a single time. I have setup the process using the ActionListener class and then have an if statement and a few else if's to determine when a button has been pressed. Not quite sure why I am getting this multiple output, it also seems to be proportional to the amount of times other buttons have been pressed.
Eg. the printout i get is like below
First test: 1133 milliseconds
Second test: 764 milliseconds
Second test: 767 milliseconds
Third test: 1461 milliseconds
Third test: 1464 milliseconds
Third test: 1466 milliseconds
Fourth test: 1533 milliseconds
Fourth test: 1536 milliseconds
Fourth test: 1538 milliseconds
Fourth test: 1539 milliseconds
Fifth test: 669 milliseconds
Fifth test: 672 milliseconds
Fifth test: 673 milliseconds
Fifth test: 674 milliseconds
Fifth test: 676 milliseconds
Sixth test: 549 milliseconds
Sixth test: 552 milliseconds
Sixth test: 554 milliseconds
Sixth test: 555 milliseconds
Sixth test: 556 milliseconds
Sixth test: 558 milliseconds
Cheers
AaronHere's the code, have two variables that store the time before the experiment is done and one that gets the time after the experiment. It then subtracts the two to work out the time taken and then prints this out to an output file.

Is it possible for me to get a JButton into and JTable? The Table contents come from the code below.
server myserver= new server();//make object of this class
network mynetwork= new network(myserver);// make network objectand pass server as refrence
int row,col;
//initialise string database for hosts
for (row=0;row<50;row++){

Headache: Data Xchange from JDialog to JTable using JButton
My head is spinning about how to get this to work. What is really confusing me is the data exchange from the JDialog.
I have a JTable where one of the columns uses a JButton as the cell editor for each cell in that column. That part seems to be no problem. The JButton is labeled "Define Staff..."
When the user clicks on the JButton, a JDialog containing a JList is to appear. If the user clicks cancel, the JDialog is disposed and nothing happens. If the user clicks OK, the selected items are to be returned to the cell in some way and the label of the JButton is to change to "Modify Staff..."
How can I return the list from the JDialog to the "cell" so that when I access the cell using getValueAt() I get the list of values, and not the JButton object?Thanks.
The actual JButton is inside a JTable cell though.
Where would I add the event handler for the button? In the editor? In the renderer?
Excerpt from the JTable file:
PositionTable.getColumn("Staff").setCellRenderer(new ButtonRenderer());
PositionTable.getColumn("Staff").setCellEditor(new ButtonEditor(new JCheckBox()));ButtonEditor.java
public class ButtonEditor extends DefaultCellEditor {
protected JButton button;
private String label;
private boolean isPushed;
public ButtonEditor(JCheckBox checkBox) {
super(checkBox);
button = new JButton();
button.setOpaque(true);
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
fireEditingStopped();
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
if (isSelected) {
} else{
button.setForeground(table.getForeground());
button.setBackground(table.getBackground());
label = (value ==null) ? "" : value.toString();
isPushed = true;
return button;
public Vector<String> getCellEditorValue() {
Vector<String> staff = new Vector<String>();
if (isPushed) {
staffSelector temp = new staffSelector(null,true,"Building Supervisor");
temp.setVisible(true);
staff = temp.getSelectedStaff(true);
isPushed = false;
// return new String( label ) ;
//Return vector people selected.
return staff;
public boolean stopCellEditing() {
isPushed = false;
return super.stopCellEditing();
protected void fireEditingStopped() {
super.fireEditingStopped();
}ButtonRenderer.java
public class ButtonRenderer extends JButton implements TableCellRenderer {
public ButtonRenderer() {
setOpaque(true);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (isSelected) {
setForeground(table.getForeground());
setBackground(table.getBackground());
} else{
setForeground(table.getForeground());
setBackground(UIManager.getColor("Button.background"));
setText( (value ==null) ? "Define Staff..." : "Modify Staff..." );
return this;

Multiple JButtons in a JTable cell: handling events
Hello!
I'm trying to develop a Swing application which makes use of tables in several panels.
Each row of each table should present the user two buttons, one for editing the row, one for viewing details of that row. Both editing and viewing are done in another panel.
I thought I could add the buttons as the last column of each row, so I made a panel which holds the two buttons and the id of the row, so that I know what I have to edit or view.
I managed to insert the panel as the last column, but I can't have the buttons click.
I studied cell renderers and editors from several tutorials and examples, but evidently I can't understand either of them: whatever I try doesn't change the outcome... :(
Below is the code I use, except for imports and packages:
ActionPanel.java - The panel which holds the buttons and the row id
public class ActionPanel extends JPanel{
private static final long serialVersionUID = 1L;
public static String ACTION_VIEW="view";
public static String ACTION_EDIT="edit";
private String id;
private JButton editButton;
private JButton viewButton;
public String getId() {
return id;
public void setId(String id) {
this.id = id;
public JButton getEditButton() {
return editButton;
public void setEditButton(JButton editButton) {
this.editButton = editButton;
public JButton getViewButton() {
return viewButton;
public void setViewButton(JButton viewButton) {
this.viewButton = viewButton;
public ActionPanel() {
super();
init();
public ActionPanel(String id) {
super();
this.id = id;
init();
private void init(){
setLayout(new FlowLayout(FlowLayout.CENTER, 10, 0))
editButton=new JButton(new ImageIcon("./images/icons/editButtonIcon.png"));
editButton.setBorderPainted(false);
editButton.setOpaque(false);
editButton.setAlignmentX(TOP_ALIGNMENT);
editButton.setMargin(new Insets(0,0,0,0));
editButton.setSize(new Dimension(16,16));
editButton.setMaximumSize(new Dimension(16, 16));
editButton.setActionCommand(ACTION_EDIT);
editButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, id, "Editing", JOptionPane.INFORMATION_MESSAGE);
viewButton=new JButton(new ImageIcon("./images/icons/viewButtonIcon.png"));
viewButton.setMaximumSize(new Dimension(16, 16));
viewButton.setActionCommand(ACTION_VIEW);
viewButton.setBorderPainted(false);
viewButton.setOpaque(false);
viewButton.setMargin(new Insets(0,0,0,0));
viewButton.setSize(new Dimension(16,16));
viewButton.setMaximumSize(new Dimension(16, 16));
viewButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, id, "Viewing", JOptionPane.INFORMATION_MESSAGE);
add(viewButton);
add(editButton);
ActionPanelRenerer.java - the renderer for the above panel
public class ActionPanelRenderer implements TableCellRenderer{
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
Component ret=(Component)value;
if (isSelected) {
ret.setForeground(table.getSelectionForeground());
ret.setBackground(table.getSelectionBackground());
} else {
ret.setForeground(table.getForeground());
ret.setBackground(UIManager.getColor("Button.background"));
return ret;
ActionPanelEditor.java - this is the editor, I can't figure out how to implement it!!!!
public class ActionPanelEditor extends AbstractCellEditor implements TableCellEditor{
public Component getTableCellEditorComponent(JTable table,Object value,boolean isSelected,int row,int column) {
return (ActionPanel)value;
public Object getCellEditorValue() {
return null;
ServicesModel.java - The way I fill the table is through a model:
public class ServicesModel extends AbstractTableModel {
private Object[][] data;
private String[] headers;
public ServicesModel(Object[][] services, String[] headers) {
this.data=services;
this.headers=headers;
public int getColumnCount() {
return headers.length;
public int getRowCount() {
return data.length;
public Object getValueAt(int row, int col) {
if(col==data.length-1)
return new ActionPanel(""+col);
else
return data[row][col];
public boolean isCellEditable(int row, int col) {
return false;
public Class getColumnClass(int column) {
return getValueAt(0, column).getClass();
ServicesList.java - The panel which holds the table (BasePanel is a custom class, not related to the table)
public class ServicesList extends BasePanel {
private JLabel label;
private JTable grid;
public ServicesList(SessionManager sessionManager){
super(sessionManager);
grid=new JTable() ;
add(new JScrollPane(grid), BorderLayout.CENTER);
layoutComponents();
public void layoutComponents(){
ConfigAccessor dao=new ConfigAccessor(connectionUrl, connectionUser, connectionPass);
String[] headers=I18N.get(dao.getServiceLabels());
grid.setModel(new ServicesModel(dao.getServices(), headers));
grid.setRowHeight(20);
grid.getColumnModel().getColumn(headers.length-1).setCellRenderer(new ActionPanelRenderer());
grid.setDefaultEditor(ActionPanel.class, new ActionPanelEditor());
grid.removeColumn(grid.getColumnModel().getColumn(0));
dao.close();
}Please can anyone at least address me to what I'm doing wrong? Code would be better, but examples or hints will do... ;)

Thanks for any helpThanks for the reply, i am now having trouble adding buttons to the dialog box. This is the code i am using:
dialog = new JDialog(f, "dialog");
dialog.getContentPane().add(new JLabel("hello world", JLabel.CENTER));
dialog.setSize(400,300);
dialog.setLocation(425,200);
JButton buttonQuestion = new JButton( "Question" );
dialog.getContentPane().add(buttonQuestion);For some reasson this turns the whole dialog pane into a button. So all i get is a dialog box with question in the middle. What i need is the hello world label to be displayed, with the questin button underneath
Thanks for any help -
Hi,
I want to add JButtons and or JCalendar components in my JTable.
How can I do this?
I have the "How to Use Tables" from sun in printed format but cannot figure out how to do this...An example of using a JButton can be found in the tutorial you mentioned
(from said tut)
public class ColorEditor extends AbstractCellEditor
implements TableCellEditor,
ActionListener {
Color currentColor;
JButton button;
JColorChooser colorChooser;
JDialog dialog;
protected static final String EDIT = "edit";
public ColorEditor() {
button = new JButton();
button.setActionCommand(EDIT);
button.addActionListener(this);
button.setBorderPainted(false);
//Set up the dialog that the button brings up.
colorChooser = new JColorChooser();
dialog = JColorChooser.createDialog(button,
"Pick a Color",
true, //modal
colorChooser,
this, //OK button handler
null); //no CANCEL button handler
public void actionPerformed(ActionEvent e) {
if (EDIT.equals(e.getActionCommand())) {
//The user has clicked the cell, so
//bring up the dialog.
button.setBackground(currentColor);
colorChooser.setColor(currentColor);
dialog.setVisible(true);
fireEditingStopped(); //Make the renderer reappear.
} else { //User pressed dialog's "OK" button.
currentColor = colorChooser.getColor();
//Implement the one CellEditor method that AbstractCellEditor doesn't.
public Object getCellEditorValue() {
return currentColor;
//Implement the one method defined by TableCellEditor.
public Component getTableCellEditorComponent(JTable table,
Object value,
boolean isSelected,
int row,
int column) {
currentColor = (Color)value;
return button;

My JButton inside a JTable cell does not respond to clicks
I have a Jtable which extends AbstractTableModel and uses an arraylist to fill the data in the model. The first column of this table is my button column. I have a class for my button coumn which is:

Renderer problem for a JButton in a JTable
Hi all,
Here is my requirement -
When the value of a particular cell in a JTable gets changed, another cell in the same selected row should display a JButton. The button should remain displayed for that row. Other rows should not have the button displayed unless there is any change in value of other columns in that row.
I have the problem in displaying the button only when the values of a particular row is changed. The button gets displayed if I click that button cell which should not happen as the values are not changed for the corresponding row. Also, once the button is displayed for a particular row, if i click some other row, button gets disappeared for the previously selected row.
Here is the code I have implemented. Please correct me where I am going wrong.
Renderer code for the button-
==================
class ButtonRenderer extends JButton implements TableCellRenderer {
public ButtonRenderer() {
setOpaque(true);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column)
if (isSelected) {
setForeground(table.getSelectionForeground());
setBackground(table.getSelectionBackground());
} else{
setForeground(table.getForeground());
setBackground(UIManager.getColor("Button.background"));
TableModel model = table.getModel();
// get values from the table model's selected row and specific column
if(// check if values are changed from old ones)
setText("Undo");
setVisible(true);
return (JButton) value;
else
JButton button = new JButton("");
button.setBackground(Color.white);
button.setBorderPainted(false);
button.setMargin(new Insets(0, 0, 0, 0));
button.setEnabled(false);
return button;
Editor code for the button -
=======================
class ButtonCellEditor extends DefaultCellEditor
public ButtonCellEditor(JButton aButton)
super(new JTextField());
setClickCountToStart(0);
aButton.setOpaque(true);
aButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
fireEditingStopped();
editorComponent = aButton;
protected void fireEditingStopped()
super.fireEditingStopped();
public Object getCellEditorValue()
return editorComponent;
public boolean stopCellEditing()
return super.stopCellEditing();
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column)
return editorComponent;
Code setting the renderer/editor -
==================================
TableColumn column = colModel.getColumn(6);
button.setVisible(true);
button.setEnabled(true);
column .setCellRenderer(new ButtonRenderer());
column .setCellEditor(new ButtonCellEditor(button));
Please correct me where I am going wrong.
Thanks in advance!!Hope this is what you want...edit the column "Value" and type "Show" to get the desired result.

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={"","","","","",""};
Statement stmt=null;
ResultSet rs=null;
PreparedStatement ps;
String query=null;
String retrieve=null;
int i,j=0;
TableColumnModel modelCol = clientTable.getColumnModel();
try{
con = DriverManager.getConnection(url);
JOptionPane.showMessageDialog(null,"Please wait while the program retrieves data.");
query="select seqNo, givenName, address1, address2, address3, address4, cardSerNr, PIN1, PrintFlag from PendPINMail where seqNo<250;";
ps = con.prepareStatement(query);
rs=ps.executeQuery();
while (rs.next()){
data[0]= rs.getString("seqNo");
data[1]= rs.getString("givenName");
data[2]= rs.getString("address1");
data[3]= rs.getString("cardSerNr");
data[4]= rs.getString("PrintFlag");
// 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. Thanksyou 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 -
