Hi Ivaylo,
My first suggestion is that you should point out more
precisely where is the core of this probrem.
Which object, which method works fine and which doesn't?
I also suggest you that you can easily test if background
is partialy working or not at all using setColor() method.
If you can see background color, renderer sees your
background node, and I suppose your imageComponent2D
may not be prepared correctly. If you can't, I suspect
your scene graph may be incorrect.
And also you can check if your image is loaded correcly
by painting it on a AWT component, and can see your
scene graph tree with a small method like this :
public static void dumpTree(PrintStream out, int indent, Node node) {
for (int i = 0; i < indent; i++) {
out.print(" ");
}
out.println(node.getClass());
if (node instanceof Group) {
Enumeration e = ((Group)node).getAllChildren();
while (e.hasMoreElements()) {
dumpTree(out, indent + 2, (Node)e.nextElement());
}
}
}
With this dumping, a small trick like
class BackgroundGroup extends BranchGroup {
}
Group yourGroupForBackground = new BackgroundGroup();
should be useful because this dumpTree() prints only class
names.
Goodluck,
Tomohiro Koike
