Tutorial java class Auto Complete ComboBox ditambah sedikit polesan jTatto.
ini codingnya :
package Latihan_Java1;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.util.Vector;
import javax.swing.DefaultComboBoxModel;
import javax.swing.JComboBox;
import javax.swing.JTextField;
public class ComboListener extends KeyAdapter
{
@SuppressWarnings("rawtypes")
JComboBox cbListener;
@SuppressWarnings("rawtypes")
Vector vector;
@SuppressWarnings("rawtypes")
public ComboListener(JComboBox cbListenerParam, Vector vectorParam)
{
cbListener = cbListenerParam;
vector = vectorParam;
}
@SuppressWarnings({ "unchecked", "rawtypes" })
public void keyTyped(KeyEvent key)
{
// TODO Auto-generated method stub
String text = ((JTextField)key.getSource()).getText();
cbListener.setModel(new DefaultComboBoxModel(getFilteredList(text)));
cbListener.setSelectedIndex(-1);
((JTextField)cbListener.getEditor().getEditorComponent()).setText(text);
cbListener.showPopup();
}
@SuppressWarnings({ "rawtypes", "unchecked" })
public Vector getFilteredList(String text)
{
Vector v = new Vector();
for(int a = 0;a<vector.size();a++)
{
if(vector.get(a).toString().startsWith(text))
{
v.add(vector.get(a).toString());
}
}
return v;
}
}
