对不起,如果这是一个愚蠢的问题。
我想了解如何调用位于
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new FereastraPrincipala().setVisible(true);
来自 AdaugaComanda.java 类。
run 方法在 FereastraPrincipala.java 中声明,我想从 AdaugaComanda.java 调用它,以便在从 AdaugaChitanta.java 的文本字段中引入值后,可以看到 FereastraPrincipala 的变化。如果我不调用方法,那么我必须再次运行 FereastraPrincipala.java,以便在 JTabbedPane 中查看新信息。
这是 FereastraPrincipala.java 的代码
package sakila.ui;
import java.util.List;
import java.util.Vector;
import javax.swing.table.DefaultTableModel;
import org.hibernate.Session;
import sakila.entity.*;
import sakila.util.HibernateUtil;
public class FereastraPrincipala extends javax.swing.JFrame {
public FereastraPrincipala() {
initComponents();
}
private void jMenuItem1ActionPerformed(java.awt.event.ActionEvent evt) {
AdaugaComanda ac = new AdaugaComanda();
ac.setVisible(true);
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new FereastraPrincipala().setVisible(true);
Session session = HibernateUtil.getSessionFactory().openSession();
try{
List<Comanda> comenzi = session.createQuery("from Comanda").list();
Vector<String> tableHeaders = new Vector<String>();
Vector tableData = new Vector();
tableHeaders.add("IdComanda");
tableHeaders.add("Depozit");
tableHeaders.add("Furnizor");
tableHeaders.add("Client");
tableHeaders.add("Produs");
tableHeaders.add("Cantitate");
tableHeaders.add("Unit de mas");
for (Comanda comanda : comenzi) {
Vector <Object> oneRow = new Vector <Object>();
oneRow.add(comanda.getIdcomanda());
oneRow.add(comanda.getDepozit() == null ? "" : comanda.getDepozit().toString());
oneRow.add(comanda.getFurnizor() == null ? "" : comanda.getFurnizor().toString());
oneRow.add(comanda.getClient() == null ? "" : comanda.getClient().toString());
oneRow.add(comanda.getProdus() == null ? "" : comanda.getProdus().toString());
oneRow.add(comanda.getCantitate());
oneRow.add(comanda.getUnitmas());
tableData.add(oneRow);
}
ComandaTable.setModel(new DefaultTableModel(tableData, tableHeaders));
}catch (Exception he){
he.printStackTrace();
}
}
});
}
}

也许有人可以帮助我。十分感谢!
