MouseClicked not triggered for JTable in a GUI with both Action and Mouse Listener


Tag : java , By : Scott Everts

this will help You don't need a MouseListener anywhere, simply let the button's Action query the table's selection state, something like
    Action delete = new AbstractAction("Delete Selected Row") {

        @Override
        public void actionPerformed(ActionEvent e) {
            if (table.getSelectedRow() < 0) return;
            int modelRowIndex = table.convertRowIndexToModel(table.getSelectedRow());
            ((DefaultTableModel) table.getModel().removeRow(modelRowIndex);
        }
    };
    JButton button = new JButton(delete);

JButton's action listener not working in JTable

it helps some times I think that while the button is shown on the table, it is not really a button but a cell that is rendered like a button.
You can listen to the table's model to see when the used clicked on a cell that has a button and act when this happens.

hop of those help? Seen as you seem to be determined to follow this path, you have a number of options...
The hard way...
public void actionPerfomed(ActionEvent e) {

    TableModel model = //... Create the new model based on you needs
    JTable table = new JTable(model);

    JFrame frame = new JFrame();
    frame.setLayout(new BorderLayout());
    frame.add(new JScrollPane(table));
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);

}
public class ModelPane extends JPanel {

    private JTable table;

    public ModelPane(TableModel model) {
        setLayout(new BorderLayout());
        table = new JTable(model);
        add(new JScrollPane(table));
    }

}

public class ModelFrame extends JFrame {

    public ModelFrame(TableModel model) {
        setLayout(new BorderLayout());
        add(new ModelPane(model));
        pack();
        setLocationRelativeTo(null);
    }

}
public void actionPerfomed(ActionEvent e) {
    TableModel model = //... Create the new model based on you needs
    ModelFrame frame = new ModelFrame(model);
    frame.setVisible(true);
}
public abstract class AbstractModelAction extends AbstractAction {

    public abstract TableModel getModel();

    @Override
    public void actionPerformed(ActionEvent e) {
        ModelFrame frame = new ModelFrame(getModel());
        frame.setVisible(true);
    }
}

public class CurrencyModelAction extends AbstractModelAction {

    @Override
    public TableModel getModel() {
        return //... Create the new model based on you needs
    }

}

I hope this helps you . For add action listner in JTable cell you can do in this way. You can rename this Calender_Table variable into calenderTable.
calenderTable.addMouseListener(new MouseAdapter() {
  public void mouseClicked(MouseEvent e) {
    if (e.getClickCount() == 2) {
      JTable target = (JTable)e.getSource();
      int row = target.getSelectedRow();
      int column = target.getSelectedColumn();
     // do some stuff
    }
  }
});
