Returns true if the value identified by path is currently viewable, which means it is either the root or all of its parents are expanded.

Usage

From source file:Main.java

public static void visitAllExpandedNodes(JTree tree, TreePath parent) {
    if (!tree.isVisible(parent)) {
        return;/*from  ww  w.j  av  a  2  s.c  o  m*/
    }
    TreeNode node = (TreeNode) parent.getLastPathComponent();
    System.out.println(node);

    if (node.getChildCount() >= 0) {
        for (Enumeration e = node.children(); e.hasMoreElements();) {
            TreeNode n = (TreeNode) e.nextElement();
            TreePath path = parent.pathByAddingChild(n);
            visitAllExpandedNodes(tree, path);
        }
    }
}
