我想將button
放置在「898 Food Restaurant」Jlabel
以下。 setLocation()
爲button
不起作用。在JAVA中使用多個佈局管理器
public class MainMenu extends JPanel{
JLabel picLabel,title;
JButton button;
public MainMenu() throws IOException
{
JPanel panel = new JPanel(new BorderLayout());
BufferedImage myPicture = ImageIO.read(new File("C:\\Users\\seng\\workspace\\FoodOrderingSystem\\ramen-noodles.png"));
Image scaled = myPicture.getScaledInstance(170,170,Image.SCALE_SMOOTH);
picLabel = new JLabel(new ImageIcon(scaled));
title = new JLabel("898 Food Restaurant");
title.setFont(new Font("Serif",Font.ITALIC+Font.BOLD,18));
title.setForeground(Color.BLUE);
button = new JButton("Order Food Now >>");
button.setLocation(40,380);
button.setSize(40,80);
panel.add(picLabel,BorderLayout.CENTER);
panel.add(title,BorderLayout.SOUTH);
JPanel buttonPanel = new JPanel();
buttonPanel.add(button);
add(buttonPanel);
add(panel);
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
OrderMainPage order = new OrderMainPage();
}
});
}
public static void main(String args[]) throws IOException
{
MainMenu main = new MainMenu();
JFrame frame = new JFrame();
frame.setTitle("898 Food Ordering System");
frame.add(main);
// frame.setSize(120,130);
frame.pack(); // size
frame.setLocationRelativeTo(null); // place frame in center
frame.setVisible(true);
}
}
嘗試垂直箱或BoxLayout的替代。 – rob
