Add a JScrollPane to a JLabel

问题

I can't seem to find out how I can add a JScrollPane to a JLabel. The JLabel that I'm using is populated with a long formatted HTML string. Please help.

area = new JLabel();

JScrollPane scroller = new JScrollPane(area, 
      JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, 
      JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);

panel.add(scroller);

Really not good idea to hold or display long Html formatted text in the JLabel, since is possible, better would be use JEditorPanes / JTextPanes, these JComponets support styled and html formatted text, Icons etc ... , examples for JTextPane and JEditorPane

Can you provide us your code? Are you setting the viewport view to the JLabel? Instantiate your JLabel and a JScrollPane. then set the JScrollPane viewport to the JLabel (setViewPortView(jlabel);) then add the JScrollPane to whatever component you want the scrolling JLabel to be on.

Hope this helps!

You can't add a JScrollPane to a JLabel , what you can do is to create a JScrollPane and add a JLabel.

You need to set the JScrollPane's viewport view:

scroller.setViewPortView(area);

stick that line just before you go panel.add(scroller);

Let us know if that helps or not.
