JTree image node

[Edward Chen]

I want to set an image icon as the tree node, not leaf icon

some thing like this
category = new DefaultMutableTreeNode("parent");
 
// something like this, but this way it doesn't work
book = new DefaultMutableTreeNode(new JLabel(imageIcon));
category.add(book);

Thanks

final Image pic0 = new Image(display, "pic0.jpg");
final Image pic1 = new Image(display, "pic2.jpg");
final Image pic2 = new Image(display, "pic2.jpg");

final Tree x = new Tree(sShell, SWT.MULTI | SWT.BORDER);
x.setSize(140, 180);
x.setLocation(10, 10);

TreeItem root = new TreeItem(x, SWT.NONE);
root.setText("My Album");
root.setImage(pic0);

TreeItem t1 = new TreeItem(root, SWT.NONE);
t1.setText("Sub Album 1");
t1.setImage(pic1);

TreeItem t2 = new TreeItem(root, SWT.NONE);
t2.setText("Sub Album 2");
t2.setImage(pic2);
------------------

Hope this helps...

Oops!....sorry,...i am dealling with SWT...
Well, by the way, I am developping the application like ACDSee and I am two-day struck on loading image file.
I mean....dynamic loadding some pix from the folder located on C:\ or A:\, for example, ...Do you have any idea?

Thanx,

About image node in JTree.
I have found an acceptable , even not perfect, solution. The key point is ,TreeCellRender is a subclass of JLabel, that mean, we can use simple setIcon, setText function of JLabel. If we want more control, we should think how to build our custom JLabel.

about load the image.
Actually I can't fully understand your question. Maybe the problem is , the image path can't be found. I guess you are using Eclipse, if this, loading image will be easy. you can use Eclipse VEP to add icon to JLabel.
