java - 如何在 Swing 中为 JDialog 重绘？

Question

如何在Swing中重绘JDialog？如果我单击 JDialog 中的转换按钮，我需要更改 JDialog 的 GUI 设计，但它没有发生？他们有什么解决办法吗？

    _convertAction = new AbstractAction() {
        public void actionPerformed(ActionEvent e) {
            String para = new String(); 
            _task.setBookTypeId(13);
             initComponents();
           //   validate();
           //   repaint();
            setVisible(true);
        }
      };

我将预订类型 ID 设置为 13。

if(_task.getBookTypeId()== 1){
    String colnames[] = {"Leg","Departure", "Date","Time", "Arrival","Date", "Time","How","Aircraft","PIC","Copilot"};
    MyTableModel mytablemodel = new MyTableModel(colnames);
    legdetailsTable = new JTable(mytablemodel);
    legdetailsTable.setRowSelectionAllowed(true);
}else {
    System.out.println("Brokered booking table");   
    String   colnames[] = {"Leg","Departure", "Date","Time", "Arrival","Date", "Time","How"};
    MyTableModel mytablemodel = new MyTableModel(colnames);
    legdetailsTable = new JTable(mytablemodel);
    legdetailsTable.setRowSelectionAllowed(true);
}

我使用 Id 在 initcomponents 方法中更改组件。

代替

legdetailsTable = new JTable(mytablemodel);

添加

legdetailsTable.setModel(mytablemodel);

您重新创建了 JTable，但新的未添加到布局中
