Nun der Code des JTable :
public class myScrollTable extends JScrollPane{
private InputMask Mask;
private DB Database;
private String[] ColumnNames = {"Name : ","Description :","Category :","State :","Creation : ","Limit : ","Resolution : "};
private JTable jTable;
private DefaultTableModel myModel;
public myScrollTable(DB Database,InputMask Mask) {
super();
this.Database = Database;
this.Mask = Mask;
initialize();
}
private void initialize() {
this.setPreferredSize(new java.awt.Dimension(800,200));
this.setViewportView(getJTable());
this.setSize(800, 200);
}
private JTable getJTable() {
if (jTable == null) {
myModel = new DefaultTableModel(Database.MakeArray(),ColumnNames);
jTable = new JTable( myModel);
jTable.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(java.awt.event.MouseEvent e) {
Point p = e.getPoint();
int row = jTable.rowAtPoint(p);
Mask.Ubdate(row);
}
});
}
return jTable;
}
public void Ubdate(int ID)
{
myModel = new DefaultTableModel(Database.MakeArray(),ColumnNames);
jTable.setModel(myModel);
}
