如何在Swing中对JDialog进行重绘？

如何在Swing中对JDialog进行重绘？ 如果我点击JDialog中的转换按钮，我需要更改JDialog的GUI设计，但它没有发生？ 他们有什么解决方案？

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

我设置的预订类型ID是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我正在改变initcomponents方法中的组件。

Answer 1

您可以获取当前Component或任何Component的Window，而不是调用repaint() 。

 SwingUtilities.getWindowAncestor( this ).repaint(); 

Answer 2

代替

 legdetailsTable = new JTable(mytablemodel); 

加

 legdetailsTable.setModel(mytablemodel); 

您重新创建JTable，但新的JTable不会添加到布局中
