Object[][] items = new Object[][]{
{1, "BridgeMill Family Medical Associates, PC"},
{4, "Diagnostic and Imaging Services",},
{3, "Northside Hospital - Cherokee"}};
JComboBox cbox = cboTestLoad;
cbox.setModel(new DefaultComboBoxModel(items));
The DefaultComboBoxModel takes a single dimensioned array as it's
parameter, not a two dimensional array. That's why you are seeing
arrays as the items in your box model.
Remove the 2nd array for this to work. What do 1,4,3, represent? If
it's some sort of internal coding you'll have to make a new type to
cache it.
E.g.:
class ComboHolder {
final private String display;
final private int num;
public ComboHolder( String display, int num )
{
this.display = display;
this.num = num;
}
@Override
public String toString()
{
return display;
}
public int getNum()
{
return num;
}
}
Here's an example:
package test;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class JCoboboxTest {
public static void main( String[] args )
{
SwingUtilities.invokeLater( new Runnable()
{
public void run()
{
initGui();
}
} );
}
private static void initGui() {
JFrame jf = new JFrame("ComboTest");
JPanel jp = new JPanel();
ComboHolder[] model = {
new ComboHolder( "String 1", 1),
new ComboHolder( "String 4", 4),
new ComboHolder( "String 3", 3),
};
JComboBox combo = new JComboBox( model );
jp.add( combo );
jf.add( jp );
combo.addActionListener( new ActionListener() {
public void actionPerformed( ActionEvent e ) {
System.out.println( ((ComboHolder)((JComboBox)e.getSource())
.getSelectedItem()).getNum() );
}
} );
jf.pack();
jf.setLocationRelativeTo( null );
jf.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
jf.setSize( 300, 300 );
jf.setVisible( true );
}
}
