jtree problem

[Tal Goldstein]

hi
im trying to change the jtree renderer to do the following:
each node in the tree should be on a panel which contains two lables,
the left label which is the node name and its icon, and the right label which would be a legend.
i already created that and it works,
the problem is that i want the legend label(the right label) to be aligned to the right of the tree, but i cant get it to work because it aligns label to the right of panel, but the panel itself isnt as wide as the tree component.
how can i tell jtree to set each of the nodes panels to be as wide as the jtree itself?

here's how it should look like:http://www16.brinkster.com/talgo/eg.jpg
this is what i get:http://www16.brinkster.com/talgo/current.jpg


thanks

I got this to work with custom TreeCellRenderer and BasicTreeUI classes. The minimum I could get by with in the UI code was this:

class BasicWideNodeTreeUI extends BasicTreeUI
{
    private int lastWidth;
    private boolean leftToRight;
    protected JTree tree;
 
    public BasicWideNodeTreeUI() 
 
    public void installUI(JComponent c) {
        if ( c == null ) {
        throw new NullPointerException( "null component passed to " +
                                        "BasicTreeUI.installUI()" );
        }
        tree = (JTree)c;
        super.installUI(c);
    }
 
    protected void prepareForUIInstall() {
        super.prepareForUIInstall();
        leftToRight = tree.getComponentOrientation().isLeftToRight();
        lastWidth = tree.getWidth();
    }
 
    protected TreeCellRenderer createDefaultCellRenderer() {
        return custom renderer
    }
 
    protected int getRowX(int row, int depth)
 
    protected AbstractLayoutCache.NodeDimensions createNodeDimensions() 
 
    public class NodeDimensionsHandler extends AbstractLayoutCache.NodeDimensions
        ...
        public Rectangle getNodeDimensions(Object value, int row, int depth,
                                           boolean expanded, Rectangle size)
            ...
            if(currentCellRenderer != null) {
                ...
                if(size != null) {
                    size.x = getRowX(row, depth);
                    size.width = //prefSize.width;
                                 lastWidth - size.x;  <*** the only change
        ... and the rest of this nested class ...
    }
}

and set the ui after the tree was realized (no size data otherwise).
I put this together with the j2se 1.5 sdk and notice (in the docs) that there have been some changes (starting in 1.5).
