How do I get a JScrollPane to always display scroll bars?

java, swing No Comments »

You can achieve this by setting the scroll bar policy on both the verical and horizontal scroll bars.


ScrollPane scrollPane = new JScrollPane(panel);

// Force the scrollbars to always be displayed

scrollPane.setHorizontalScrollBarPolicy(
   JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollPane.setVerticalScrollBarPolicy(
   JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
