这是我的第一个问题......
我有一个小程序，它有一个主框架，其中有两个独立的面板（workConfig和WorkTable）。
在第一个面板上添加了Jtable，在第二个面板上添加了一个小配置..
所以在我向我的jtextfields添加了一些文本后，我将所有数据放在一起并将其交给我的名为workstate的类。在此课程中，方法addCompany()应将数据添加到unternehmen（英语：公司）和LinkedList中的班级jTable。添加两个东西都没问题，但我的Jtable在添加新数据后没有刷新....
我尝试使用repaint()或fireChangedData()解决问题，但没有任何效果......
有人知道如何解决它？
这是我的班级工作状态
public class WorkState {
public LinkedList <Unternehmen> company = new LinkedList();
public WorkTable workTable = new WorkTable();
JLabel label;
public WorkState(){
}
public void addCompany(Unternehmen neu, JLabel label) {
// TODO Auto-generated method stub
company.add(neu);
workTable.addCompany(neu);
setLable(label);
System.out.println(calCost());
}
public LinkedList<Unternehmen> getCompanyList(){
return company;
}
public String setString(){
String a = "0" ;
for (int i = 0; i < company.size(); i++){
a = a + " " + company.get(i).cost;
}
return a;
}
public int calCost(){
int all = 0;
for (int i = 0; i< company.size();i++){
try {
String cost = company.get(i).cost;
NumberFormat numberFormat = NumberFormat.getCurrencyInstance();
final Number parse = numberFormat.parse(cost);
all += parse.intValue();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return all;
}
public void setLable(JLabel label){
String cost = String.valueOf(calCost());
label.setText(cost);
}
}
这里是我的班级工作台
public class WorkTable extends JPanel {
/**
*
*/
private static final long serialVersionUID = 2053446323153016974L;
final String[] columnNames = {"Firma", "Datum", "Kosten"};
public DefaultTableModel tableModel = new DefaultTableModel(columnNames, 0);
public JTable table = new JTable(tableModel);
public WorkTable(){
createGui();
}
private void createGui() {
JScrollPane pane = new JScrollPane(table);
setBorder(BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(), "Unternehmen"));
setLayout(new BorderLayout());
tableModel.addTableModelListener(new TableModelListener(){
@Override
public void tableChanged(TableModelEvent arg0) {
// TODO Auto-generated method stub
System.out.println("Anzahl: " + table.getRowCount());
System.out.println("Anzahl der Element: " +Main.state.company.size());
}
});
add(pane, BorderLayout.CENTER);
// TODO Auto-generated method stub
}
public void addCompany(Unternehmen u){
tableModel.addRow(new Object []{u.name,u.date,u.cost});
}
}
使用此类actionEvent我将我的数据提供给workState
public class WorkConfig extends JPanel{
JCheckBox ja, nein;
final public static JTextField tfdCompany = new JTextField();
final public static JFormattedTextField tfdCost = new JFormattedTextField( NumberFormat.getCurrencyInstance());
final public static JFormattedTextField tfdDate = new JFormattedTextField(new Date());

}
}
});
buttonConfig.add(btnDelete);
btnDelete.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
System.out.println("button click");
for (Unternehmen u : Main.state.company ){
System.out.println(u.toString());
}
System.out.println("Gesamtkosten: " + Main.state.getCost());
}
});
buttonConfig.setMinimumSize(new Dimension(300,75));

buttonConfig.setPreferredSize(new Dimension(300,75));
this.add(buttonConfig);
//create allPanel

allConfig.setBorder(BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(),"Übersicht"));
allConfig.setLayout(new BorderLayout());
allConfig.add(new JLabel("Gesamtkosten: "),BorderLayout.WEST);
allConfig.add(lbKosten, BorderLayout.CENTER);
this.add(allConfig);
}
public static void checkConfig() throws WorkConfigException {
if ( tfdCompany.getText().isEmpty()){
throw new WorkConfigException("Bitte tragen Sie ein Unternehmen ein!");
}
if (tfdCost.getValue().equals(0) ){
throw new WorkConfigException("Bitte kontrollieren Sie die Eingabe der Kosten!");
}
String time = new SimpleDateFormat("dd.MM.yyyy").format(new Date());
if (tfdDate.getText().equals(time)){
throw new WorkConfigException("Bitte tragen Sie ein anderes Datum ein!");
}
}
public static void addCompany(){

String date = tfdDate.getText();
String cost = tfdCost.getText();
Unternehmen neu = new Unternehmen(name,date,cost);
Main.state.addCompany(neu,lbKosten);
}
}
编辑：我认为问题出在workTable和workState类之间......
