Tranfer data from a jdialog to a frame!

Question

Hello, everybody?!That is my doubt!!There's a jtable inside a jdialog, when a row was selected, and the "enter" key was pressed, i'd like to send the data to a frame (main).How could i create that?Thanks!!

Answer 1

here's something rough - just sets the selection as the label's text. modify for the row data
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.table.*;
class Testing
  JLabel selection = new JLabel("Selected Value = ");
  public void buildGUI()
    JButton btn = new JButton("Get Selection");
    final JFrame f = new JFrame();
    f.getContentPane().add(selection,BorderLayout.NORTH);
    f.getContentPane().add(btn,BorderLayout.SOUTH);
    f.setSize(200,80);
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
    btn.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        final JDialog d = new JDialog();
        Object[] cols = {"A","B","C"};
        Object[][] data = {{1,2,3},{4,5,6},{7,8,9},{10,11,12},{13,14,15}};
        final JTable table = new JTable(data,cols){
          public boolean isCellEditable(int row, int col){
            return false;
        JScrollPane sp = new JScrollPane(table);
        sp.setPreferredSize(new Dimension(100,100));
        d.setModal(true);
        d.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
        d.getContentPane().add(sp);
        d.pack();
        d.setLocationRelativeTo(f);
        Action enterAction = new AbstractAction(){
          public void actionPerformed(ActionEvent ae){
            selection.setText("Selected Value = " +
            table.getValueAt(table.getSelectedRow(),table.getSelectedColumn()));
            d.dispose();
        InputMap im = table.getInputMap(JTable.WHEN_FOCUSED);
        KeyStroke enter = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
        im.put(enter, "enter");
        table.getActionMap().put(im.get(enter), enterAction);
        d.setVisible(true);
  public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
}
