如上图 JDialog的小例子，运行时显示不完整（左侧图），但用鼠标托动一下，改变下大小，就会显示完整（如右图），请大虾们指教，怎么才能一下子显示完整。
代码如下：
dialog.getContentPane().add(panel);
b1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
dialog.setDefaultLookAndFeelDecorated(true);
dialog.setSize(180, 120);
dialog.setLocationRelativeTo(null);
dialog.setVisible(true);
dialog.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
dialog.dispose();
}
}); JPanel panel = new JPanel();
JLabel text = new JLabel("设置成功！");
JButton b1 = new JButton("确定"); GridBagLayout layout = new GridBagLayout();
panel.setLayout(layout);
GridBagConstraints constraints = new GridBagConstraints();
constraints.weightx = 100;
constraints.weighty = 100;
constraints.gridx = 0;
constraints.gridy = 1;
constraints.gridwidth = 2;
constraints.gridheight = 1;
panel.add(text, constraints);
constraints.gridy = 2;
panel.add(b1, constraints);
dialog.getContentPane().add(panel);
b1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
dialog.setDefaultLookAndFeelDecorated(true);
dialog.setSize(180, 120);
dialog.setLocationRelativeTo(null);
dialog.setVisible(true);不是Size的问题，设大了显示也不完整，还是要用鼠标拖一下才能显示。
dialog.repaint();
dialog.repaint();
都试了，还是不行啊
你看是不是你的jframe等其他相关代码的问题
