我正在尝试在表单中添加一个按钮,将用户带回上一个屏幕。我可以显示表单和绘制的对象但无法显示按钮。 任何帮助将不胜感激
public static JButton mainMenue = new JButton("Main Menue");
public static void main(String[] args)
{
//creating and setting the values for the Jframe
JFrame form = new JFrame();
Color backColour = new Color(153,153,153);
form.getContentPane().setBackground(backColour);
form.add(mainMenue);
mainMenue.setVisible(true);
mainMenue.setLocation(100,100);
form.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
form.setBounds(30, 30, 1000, 1000);
form.getContentPane().add(new Layout());
form.setVisible(true);
}
@Override
public void paint(Graphics g)
{
//creating the seating
Font titleFont = new Font("Dialog", Font.BOLD, 36);
Font subTitleFont = new Font("Dialog", Font.BOLD, 14);
Graphics2D g2 = (Graphics2D) g;
super.paint(g);
g.setColor(Color.blue);
g.drawLine(225, 60, 255, 60);
g.drawLine(340, 60, 400, 60);
g.drawLine(400, 60, 400, 135);
g.drawLine(400, 135, 650, 135);
g.drawLine(650, 135, 650, 60);
g.drawLine(650, 60, 680, 60);
g.drawLine(765, 60, 825, 60);
