DISCONTIGUOUS_TREE_SELECTION

DISCONTIGUOUS_TREE_SELECTION
This is the default mode for the default tree selection model. With this mode, any combination of nodes can be selected.

I want to retrieve those nodes that are selected with the CTRL key (Metal look and feel),be it grouped or isolated.i read through the API but could'nt find the right method.Anybody knows how ?

I had tried this method earlier.the problem i had was if one holds down the CTRL key before selecting the nodes,a loop over path.length returns correctly the selected nodes,however if a node is selected and the CTRL key is held for subsequent selections ,the method returns duplicate selected nodes.have u encountered this ? give it a try !!!

Mick Barry

no i haven't encoutered that.
can you post a small compilable example that reproduces the problem.

object u seem to be right.i just made a simple app and it worked fine either way.i'm in transit now and on windows.earlier i had this problem on linux and need to check with my code to see what i made wrong,but i'm convinced now something was wrong.
Thanks a lot .i guess i will have to split this one between u and Manuel.His url is very helpful.
Thanks once again and enjoy ur day.

Anybody wants to show me the way ?
i am extracting the selected paths with the following
public void valueChanged( TreeSelectionEvent event )
      {
            if( event.getSource() == tree )
            {
                                    TreePath[] paths = tree.getSelectionPaths();
                  if(paths==null)
                   return;
                  for(int i=0;i<paths.length;i++){
                  System.out.println( "Selected paths=" + paths[i]);
                  }
                  System.out.println( "=====================" );
            }
      }
the result is the following
Selected paths=[JTree, colors]
Selected paths=[JTree, colors, blue]
Selected paths=[JTree, colors, violet]
=====================
i want to retrieve the strings colors,blue,violet in each selected path.i initially thought of using the toString() method on paths[i] and then store it in another String array and then StringTokenizer it.this appears to be pretty inefficient to me.If anybody knows how best i can go around this problem kindly enlighten me.
Thanks in advance.
NB ofcourse if u request for points it will be given.

Mick Barry

to get the nodes use:

Object[] path = paths[i].getPath();
