我通过netbeans用Java编写了一个程序,在现有项目中我想添加秒表。我有以下java秒表代码,但我无法确定将其嵌入程序的方法:
//All the imports were written here (I deleted them to make the code clear)
public class NewJFrame extends javax.swing.JFrame {
Toolkit toolkit;
Timer timer;
public NewJFrame() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JTextField field;
private JButton button;
private int tick;
private Timer timer;
public TestPane() {
field = new JTextField(10);
field.setEditable(false);
button = new JButton("Start");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
button.setEnabled(false);
tick = 0;
timer.start();
}
});
timer = new Timer(1000, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
field.setText(Integer.toString(++tick));
if (tick > 4) {
timer.stop();
button.setEnabled(true);
}
}
});
timer.setInitialDelay(0);
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
add(field, gbc);
add(button, gbc);
}
}

javax.swing.UIManager.setLookAndFeel(info.getClassName());
break;

System.out.format("About to schedule task.%n");

});

我无法确定什么是TestPane,以及没有TestPane我该怎么做,因为在上面的代码中,gui元素是通过编写java代码生成的,但在我想要嵌入它的程序中,我使用了netbeans gui生成器来生成所有的gui元素。
那么我该如何嵌入它呢?
