Problem in GVTTreeWalker ?
Hello !
I'm using the GVTTreeWalker class to iterate through a GVT Tree. When I used it previously for iterating beginning from the GVT root of the tree, I had no problem.
But when I tried to begin to iterate from another node, an exception is raised in the setCurrentGraphicsNode method of the class. The reason is the following code :
if (node.getRoot() ! gvtRoot) {
throw new IllegalArgumentException("The node "+node+" is not part of the document "+gvtRoot);
}
I think the exception will always be raised if the beginning node is not the root node of the GVT Tree (because node.getRoot() returns the tree root Node). So it is impossible to begin with another node than the root.
Am I right ?

Not any more. I checked in a slightly modified version of
GVTTreeWalker that let's you start with any element in the tree.
The walk should be restricted to that subtree.
