我是新来的 . 我用Java编写了一个简单的程序，而GUI用的是GridBagLayout . 问题是，在触摸窗口边框以调整框架大小之前，它没有很好的分页 . 这是我的意思的一些图片：
The main window before I resize the frame
The main window after I resize the frame
我的代码的一部分：
public class TW2Tempi
{
public static void main(String[] args)
{
MainFrame mf = new MainFrame();
}
}
class MainFrame extends JFrame
{
GridBagConstraints gbc = new GridBagConstraints();
//other variables .....
public MainFrame()
{
super("Calcola i tempi dei tuoi attacchi");
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new GridBagLayout());
setPreferredSize(new Dimension(500, 300));
setMinimumSize(new Dimension(500, 300));
//setResizable(false); //I would also like to add this but then I wouldn't be able to "resize" and see everything (second picture)
//row 1 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
//where gbc.gridy = 0
nobile = new JLabel("Orario di arrivo del nobile", SwingConstants.RIGHT);//right align
gbc.fill = GridBagConstraints.BOTH;
gbc.gridx = 0;
gbc.gridy = 0;
gbc.gridwidth = 1;
gbc.insets = new Insets(7,10,0,0);
gbc.fill = GridBagConstraints.BOTH;
add(nobile, gbc);
....
我是否必须以不同的方式初始化 GridBagConstraints ？
