分享JPanel removeAll()再add(),原来图像是删了,但是新的图像却出不来了.高手来看看要怎么做!!
public void jButton18_actionPerformed(ActionEvent e) {
Screen_jPanel.removeAll();
//repaint();
Screen_jPanel.add(new FuctionBean());
// repaint();
//update();
Screen_jPanel.setVisible(true);
update(Screen_jPanel.getGraphics());
repaint();
}
我把repain(),update(),都试了.就是不行.
