Here is the screenshot of what I want to do :
What's happening there is the JButton shows correctly but nothing happens when I click on it. After some search, I've found that the Object
returned by table.getValueAt()
is a String instead of a JButton...
Here is the code :
tblResult = new JTable(data,cols) { public TableCellRenderer getCellRenderer( int row, int column ) { return new ClientsTableRenderer(); } };
I use this for populating at run-time the JTable : (tblResult
is now Clients.rblResult
)
SwingUtilities.invokeLater( new Runnable() { public void run() { DefaultTableModel aModel = new DefaultTableModel() { //setting the jtable read only @Override public boolean isCellEditable(int row, int column) { return false; } }; String[] cols = {"N°","Société", "TVA", "CP", "Ville", ""}; aModel.setColumnIdentifiers(cols); Object[] temp = new Object[6]; for(int i=0;i<result.length;i++) { temp[0] = result[i].custNumber; temp[1] = result[i].name; temp[2] = result[i].tva; temp[3] = result[i].cp; temp[4] = result[i].city; temp[5] = "Consulter"; aModel.addRow(temp); } Clients.tblResult.setModel(aModel); Clients.tblResult.addMouseListener(new JTableButtonMouseListener(Clients.tblResult)); }} );
Here the ClientsTableRenderer
class
public class ClientsTableRenderer extends JPanel implements TableCellRenderer { @Override public Component getTableCellRendererComponent( final JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { setBackground(Color.WHITE); if(column < 5) { JLabel label = new JLabel(value.toString()); JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER,0,9)); panel.setBackground(Color.WHITE); panel.add(label); this.add( panel); } else { JButton button = new JButton(value.toString()); button.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { System.out.println("Clicked !"); } }); JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER,0,3)); panel.setBackground(Color.WHITE); panel.add(button); this.add(panel); } return this; } }
And finaly, the JTableButtonMouseListener() :
public class JTableButtonMouseListener extends MouseAdapter { private final JTable table; public JTableButtonMouseListener(JTable table) { this.table = table; } @Override public void mouseClicked(MouseEvent e) { int column = table.getColumnModel().getColumnIndexAtX(e.getX()); int row = e.getY()/table.getRowHeight(); System.out.println("Col :"+column + "row:"+row); if (row < table.getRowCount() && row >= 0 && column < table.getColumnCount() && column >= 0) { Object value = table.getValueAt(row, column); System.out.println("Value :"+value.getClass().getName()); if (value instanceof JButton) { ((JButton)value).doClick(); } } } }
I'm kindly new to Java, help would be very much appreciated :)
Thanks in advance !
We can add or insert a JButton to JTable cell by customizing the code either in DefaultTableModel or AbstractTableModel and we can also customize the code by implementing TableCellRenderer interface and need to override getTableCellRendererComponent() method.
browse command saying "method browse(URI) in the type Desktop is not applicable for the arguments (String)" To fix the error create a function/method that will take a string parameter the call the above function in the event Listener Action performed button. Call the method like this.
The isCellEditable() method of JTable (or the TableModel) controls whether a cell is editable or not. By default it just return "true". So you can override the method to return a boolean value that is set by your "Modify" button.
This Table Button Column from Rob Camick may fit your needs.
