// Create a text component
    JTextComponent textComp = new JTextPane();
    
    // Get the root view
    View v = textComp.getUI().getRootView(textComp);
    
    // Walk the view hierarchy
    walkView(v, 0);
    // Recursively walks a view hierarchy
    public void walkView(View view, int level) {
        // Process view...
    
        // Get number of children views
        int n = view.getViewCount();
    
        // Visit the children of this view
        for (int i=0; i<n; i++) {
            walkView(view.getView(i), level+1);
         }
