JDialog显示问题

[小贝壳666]

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);

那你一开始就把JDialog的size设大点不行吗？而且代码不完整，不知道你new了dialog又干了啥，下回记得贴完整代码，别人也好调

[小贝壳666]

谢谢楼上的：完整代码如下

                final JDialog dialog = new JDialog(jframe, "提示", 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。

沉了，没人会啊？

[Tassdars]

我拿你的代码跑了一下，只在前面加了一句JFrame jframe = new JFrame();

然后一点问题也没有，可以正常显示，我搞不懂了。

[linyuzhi]

我在我机子上试了一下，没有你说的问题啊！

你加入这一条试试，刷新一下。
dialog.repaint();

[小贝壳666]

JFrame jframe = new JFrame();
dialog.repaint();
都试了，还是不行啊

跟4楼一样，我也试了，没有问题。
你看是不是你的jframe等其他相关代码的问题

将完整代码(包括测试代码) 发上来看看。。

就楼主你有问题，别人都正常显示了。
