SampleTree.java Source code .
import javax.swing.tree.* ;
import javax.swing.* ;
public class SampleTree extends JTree
     public SampleTree() {
          super() ;
     public SampleTree( Object[] value ) {
          super( value ) ;
     public SampleTree( TreeModel newModel ) {
          super( newModel ) ;
this is the line creating problem
when my class is trying to call super( root )
     public SampleTree( TreeNode root ) {
          super( root ) ;
     public SampleTree( TreeNode root, boolean asksAllowsChildren ) {
          super( root , asksAllowsChildren ) ;
NOTE : when i log in to X server JTree object gets constructed properly
My requirment is it should also get constructed properly , even if X is down.
i tried hard and i am frusted
any help is appreciated
thank in advance

Answer 1

thanks thomas for your reply
but i think , we need to find out the point where it actually gets environment settings
there must be 2 things done before creation is done.
1]
Actual Construction of the Tree
2]
then getting look and feel of the underlaying OS
if we can find out step between 1 and 2 , we will get the problem ...
what say ??
dont think i am giving any suggestions to you . this is just what i think.
Please let me know if any of ur friends are facing the same problem.
