Multi-cell edit of JComboBoxes in JTable

[Joseph Sheridan]

Hello,

I'm new to Swing and I wonder if anybody could give me any idea how to go about setting up a JTable which would allow JComboBoxes in multiple cells to be amended at once. Unfortunately I haven't been able to find any examples using Google etc.

Many thanks for any ideas,

Joseph

I'm not sure what exactly you mean by amended here.

The way a JTable's cell editor works is that only one cell can be edited at a time. If you want, you can use a JComboBox in an editor and repopulate it every time the user starts editing a cell.

not tried it with comboboxes in a JTable, but normally you would just set their models the same

    
import javax.swing.*;
import java.awt.*;
class Testing
{
  public void buildGUI()
  {
    String[] cities = {"London","Madrid","New York","Paris","Rome","Sydney","Tokyo","Toronto"};
    JComboBox cbo1 = new JComboBox(cities);
    JComboBox cbo2 = new JComboBox();
    JComboBox cbo3 = new JComboBox();
    cbo2.setModel(cbo1.getModel());
    cbo3.setModel(cbo1.getModel());
    JFrame f = new JFrame();
    f.getContentPane().add(cbo1,BorderLayout.NORTH);
    f.getContentPane().add(cbo2,BorderLayout.CENTER);
    f.getContentPane().add(cbo3,BorderLayout.SOUTH);
    f.pack();
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
  }
  public static void main(String[] args)
  {
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
      }
    });
  }
}

Hello,

many thanks Brian and Michael for your comments / example. Sorry I haven't been clear about what I'm trying to achieve. I want to have a column in a JTable with a JComboBox with values. I would like to be able to select a number of cells in this column and then use the JComboBox in one of these cells to select a value which would then be applied to all the selected cells.

Thanks again for your help,

Joseph
