java - 将JTable添加到JScrollPane




swing (2)

我一直在做一个包含JTable的小应用程序。 问题是这样的:当我将JTable添加到JScrollPane ,它给我的错误是表组件添加到父组件不止一次。

getContentPane().add(new JScrollPane(table));
scrollPane.setViewportView(table);

我看到这个问题,但解决不了。 有什么建议么?

错误是正确的: JScrollPane只能有一个JViewport视图显示的可滚动客户端(又名数据模型)”。 如果“ 直接向JScrollPane构造函数提供视图”,则只需要setViewportView()

JTable table = new JTable(data, col);
add(new JScrollPane(table));

另外,不要以这种方式使用setBounds() 。 相反,重写Scrollable接口方法getPreferredScrollableViewportSize()pack()封闭窗口,如下所示。

JTable table = new JTable(model) {

    @Override
    public Dimension getPreferredScrollableViewportSize() {
        return new Dimension(1024, 512);
    }
};
add(new JScrollPane(table));
pack();

JTable table = new JTable();
JScrollPane scrollPane = new JScrollPane(table);
JFrame frame = new JFrame();
frame.add(scrollPane);

应该完美地工作。
