Adding JTable to empty JScrollPane

Hi All,

Having an issue, where I'm unable to add a table to a scrollpane if the scrollpane is already displayed.

Basically I have a search dialog which has an empty scrollpane, and I want to populate it with a Jtable of results once search is completed.

A snippet (example data, columns):

Code:

---

String[][] data = {{"aaa"}, {"bbb}};
String[] col = {"col1", "col2"};
DefaultTableModel model = new DefaultTableModel(data,col);

tableView = new JTable(model);

tableScroller.add(tableView); //JScrollPane, already instantiated
tableView.setFillsViewportHeight(true);

---

I feel like i'm missing something simple....


Thanks!

You don't add a component to the JScrollPane itself but rather you add it to the JScrollPane's JViewport. So try instead:

Code:

---

tableScroller.getViewport().add(tableView);

---

And let us know if this helps.

Worked like a charm, thanks Fubarable. I'm curious to know, when instantiating a scrollpane, you can add directly to it. Is it because the constructor scrollpanel constructor can take a table instance as a parameter and add it directly to viewport?

Thanks again!

Yes. The constructor will automatically add the component to the viewport.

And then there's JScrollPane#setViewportView (and companion methods setRowHeaderView / setColumnHeaderView)
