我有一个简单的gui,假设显示表(JTable)。如何在x秒后切换到table1(JTable),然后在x秒后返回表并在循环中运行。我知道设置另一个表只不过是把这一行放在:
scrollPane.setViewportView(table1);
但是如何从一个切换到另一个并定期返回。我猜我必须使用Timer但需要一些帮助。谢谢
以下是简单的示例代码:
public class t extends JFrame {
private JPanel contentPane;
private JTable table;
private JTable table1;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
t frame = new t();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public t() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(new BorderLayout(0, 0));
JScrollPane scrollPane = new JScrollPane();
contentPane.add(scrollPane, BorderLayout.CENTER);
table = new JTable(10,10);
table1 = new JTable(10,5);
scrollPane.setViewportView(table);
}
}
最终结果:
public class t extends JFrame {
private JPanel contentPane;
private JTable table;
private JTable table1;
private Timer timer;
private Timer timer1;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
t frame = new t();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public t() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(new BorderLayout(0, 0));
JScrollPane scrollPane = new JScrollPane();
contentPane.add(scrollPane, BorderLayout.CENTER);
table = new JTable(10,10);
table1 = new JTable(10,5);
scrollPane.setViewportView(table);
ActionListener action = new ActionListener()
{
@Override
public void actionPerformed(ActionEvent event)
{
timer.stop();
scrollPane.setViewportView(table1);
timer1.start();
}
};
ActionListener action1 = new ActionListener()
{
@Override
public void actionPerformed(ActionEvent event)
{
timer1.stop();
scrollPane.setViewportView(table);
timer.start();
}
};
timer = new Timer(3000, action);
timer.start();
timer1 = new Timer(3000, action1);
}
}
这是我想要的工作示例。谢谢大家的帮助
