java - 如何在Swing中为JDialog进行重绘？

如何在Swing中为JDialog进行重绘？
如果我在JDialog中单击转换按钮，我需要更改JDialog的GUI设计，但是没有发生吗？他们有什么解决方案吗？

    _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);
}

使用Id我正在initcomponents方法中更改组件。

最佳答案

您可以获取当前组件或任何组件的窗口，然后调用repaint()。

SwingUtilities.getWindowAncestor( this ).repaint();
