我无法重画我的jTable。我必须重新运行所有应用程序以显示addRow。
这是代码:
MainPage.java http://pastebin.com/6FZL1pKC
public class Mainpage2 extends javax.swing.JFrame {
public static DefaultTableModel tripModel;
/**
* Creates new form carpoolingui
*/
public Mainpage2(){
try {
tripModel = MPtable.myModel(Parser.parsa_tratta(Database.doRequest("SELECT * from tratte")));
} catch (Exception ex) {
Logger.getLogger(Mainpage2.class.getName()).log(Level.SEVERE, null, ex);
}
initComponents();
}
....
jTable1.setModel(tripModel);
....
public void tripRepaint() throws MalformedURLException, Exception{
System.out.println(jTable1.getModel());
tripModel = MPtable.myModel(Parser.parsa_tratta(Database.doRequest("SELECT * from tratte")));
jTable1.setModel(tripModel);
jTable1.repaint();
System.out.println(jTable1.getModel());
System.out.println(tripModel);
这最后3个println()表明模型已经改变了! 大声笑{} 输出:
Tratta AGGIUNTA
javax.swing.table.DefaultTableModel@1ca7e4a
BOLOGNA
...
卡坦札罗
NEW_DEPARTURE_ADDED
javax.swing.table.DefaultTableModel@17d54dd
javax.swing.table.DefaultTableModel@17d54dd
所以它有效..但它没有显示新模型!!

for (i=0; i<tratta_array.length; i++){
System.out.println(tratta_array[i].getLuogoPartenza());
}
for (i=0; i<tratta_array.length; i++){
model.addRow(new Object[] {
tratta_array[i].getId(),

tratta_array[i].getAutista(),

}
);
}
return model;
}

您需要通知表格,结构和/或数据已更改。问题在这里得到解答,例如:JTable How to refresh table model after insert delete or update the data.
