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 !
