How to increase the size of JScrollPane pane?

Question

  scrollPane = new JScrollPane(table);
  panel1.add( scrollPane,BorderLayout.CENTER );

Is there a way I can make the scrollPane bigger (wider) ?

I don't understand the question.. Resize it's parent element..? — Sorceror, Jun 14 '11 at 17:50

JScrollPane scrollPane = new JScrollPane(table, 
                                        JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
                                        JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
JScrollBar bar = scrollPane.getVerticalScrollBar();
bar.setPreferredSize(new Dimension(40, 0));

This works. I figured it out.

[Don't set the preferred size](http://stackoverflow.com/questions/7229226/should-i-avoid-the-use-of-setpreferredmaximumminimumsize-methods-in-java-swi). Override `getPreferredSize` instead. – user1803551 Feb 17 '16 at 13:33

When using Border Layout you don't control the size of the somponents in it Consider using GridBag Layout.

The JScrollPane is as big as the element it holds. You should make those element(s) wider.

Also, there is the setSize()-method. But you'll most likely want to use the setPreferredSize()-method as mentioned by mre.

`setPreferredSize()` is probably more preferable. – mre Jun 14 '11 at 17:51
