Inserting an Image into a JList

Question

I am trying to load an Image into a List but I can't seem to get it to work. I have tried

ImageIcon pic = new ImageIcon("http://i3.ytimg.com/vi/68X8RUxeXeA/default.jpg");
JLabel picLbl = new JLabel(pic);

Object[] lol = {picLbl, "pic", "length"};
list = new JList(lol);
scrollPane.setViewportView(list);
list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

That just puts javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,border=,flags=8388608,maximumSize=,minimumSize=,preferredSize=,defaultIcon=http://i3.ytimg.com/vi/68X8RUxeXeA/default.jpg,disabledIcon=,horizontalAlignment=CENTER,horizontalTextPosition=TRAILING,iconTextGap=4,labelFor=,text=,verticalAlignment=CENTER,verticalTextPosition=CENTER]

Instead of the actual picture. I have looked around for a while but can't seem to find anything that works. If any of you guys know how to achieve this, any help will be greatly appreciated.

Thanks in advance

Jlabels cannot be displayed by JList. Create an ImageIcon from your Image and use that for your array of elements.

If you want to know more about how a JList actually displays elements, read http://docs.oracle.com/javase/tutorial/uiswing/components/list.html#renderer

I already looked at that but I can't seem to get that to work. They didn't make it very easy to understand. – XliteRSPS Sep 16 '12 at 13:30
What will happen if you use ImageIcon instead of JLabel? – Jakub Zaverka Sep 16 '12 at 13:57
@JakubZaverka: A `DefaultListCellRenderer` _is_ a `JLabel`; more [here](http://stackoverflow.com/a/12448037/230513). – trashgod Sep 16 '12 at 15:13
@thrashgod yes thats correct. But this was a case where JLabels were actually the elements in the list. Though it may seem strange, DefaultListCellRenderer doesn't know how to display JLabels. – Jakub Zaverka Sep 16 '12 at 22:59
@JakubZaverka: D'oh, you're right; thanks for clarifying. The default [renderer](http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#editrender) "displays the object's string value." – trashgod Sep 17 '12 at 18:29

A DefaultListCellRenderer is a JLabel, so you can use setIcon() with an ImageIcon. This related example may be a useful starting point.
