Adding JTable to JScrollPane

Question

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);

I see the problem but could not solve it. Any suggestions?

`I see the problem but could not solve it.` - what do you mean you can't solve it? Get rid of one of those statements? We can't tell you what to do because we don't know what your requirement is. — camickr, Sep 08 '15 at 14:26
Thanks, Yes, I did took out one of those statements but when i took out, the table did not display. — Latif, Sep 09 '15 at 06:16

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

Should work perfectly.

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));

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();

@Laddie: You might verify that the [example](http://stackoverflow.com/a/13919878/230513) works and then compare it to your code. Ensure that `setVisible()` _follows_ construction. Failing that, please edit your question to include a [complete example](http://stackoverflow.com/help/mcve) that exhibits the problem. – trashgod Sep 09 '15 at 07:34
Now you can take a look at it. by the way , don not care about the nulls . – Latif Sep 09 '15 at 07:50
@Laddie: That's way too much uncompilable code. I still see two instances of `JScrollPane` with the same table and a premature call to `setVisible()`. – trashgod Sep 09 '15 at 08:14
Thanks again. But I only used one JScrollPane for the table . – Latif Sep 09 '15 at 09:36
When i get rid of add(new JScrollPane(table)); it gave me the error WindowBuilder encountered unexpected internal error. This could be caused by a WindowBuilder bug or by a misconfiguration issue, conflict, partial update, etc. java.lang.ArrayIndexOutOfBoundsException: 22 – Latif Sep 09 '15 at 09:40
And when get rid of scrollPane.setViewportView(table); it gave me: the table component is added to a parent component more than once. getContentPane().add(new JScrollPane(table)); scrollPane.setViewportView(table); – Latif Sep 09 '15 at 09:42
