将JTable添加到JScrollPane [英] Adding JTable to JScrollPane
本文介绍了将JTable添加到JScrollPane的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直在制作一个包含JTable的小型应用程序.问题是这样的:当我将JTable添加到JScrollPane时，这给了我一个错误，即表组件多次添加到父组件中.
I have been making a small application containing JTable. The question is this: when I am adding the JTable to the JScrollPane, it is giving me the error that the table component is added to a parent component more than once.
getContentPane().add(new JScrollPane(table));
scrollPane.setViewportView(table);
我看到了问题，但无法解决.有什么建议吗?
I see the problem but could not solve it. Any suggestions?

推荐答案
错误是正确的: JScrollPane 只能在JViewport视图中显示一个可滚动客户端(也称为数据模型)".您只需要 setViewportView() 如果您"不直接将视图提供给JScrollPane构造函数."
The error is correct: a JScrollPane can only have one "scrollable client (aka data model) displayed by the JViewport view." You only need setViewportView() if you "don't provide the view directly to the JScrollPane constructor."
JTable table = new JTable(data, col);
add(new JScrollPane(table));
顺便说一句，请勿以这种方式使用setBounds().相反，请覆盖Scrollable接口方法getPreferredScrollableViewportSize()和pack()封闭窗口，如此处所示. >
As an aside, don't use setBounds() in this way. Instead, override the Scrollable interface method getPreferredScrollableViewportSize() and pack() the enclosing window, as shown here.
JTable table = new JTable(model) {
@Override
public Dimension getPreferredScrollableViewportSize() {
return new Dimension(1024, 512);
}
};
add(new JScrollPane(table));
pack();
