Not able to highlight the file in JTree

Hi,

I have created a JTree in which I want to highlight a file and if the directory containing the file is invisible, I need to expand it.

Ex: I have created a JTree with the root node- D:/Company/abb/src. The file which I want to highlight is - D:/Company/abb/src/bin/help.txt

Please give me some logic to highlight the file help.txt.

Thanks in advance

• JTree.makeVisible() should be what you need.

  Bombe : That depends on the model of your JTree. You can construct a TreePath by specifying the single components that make up the path. Check the documentation.

  : Can u plz give me an example to build the TreePath. I am using DefaultTreeModel. It helps me a lot.

  DR : AFAIK you have to create your own model for this kind of feature.

• I have a JTree which represents the file system. Here's my code to cause a specific directory to be selected (and the tree expanded and the view scrolled if required).

  JTree fsTree;
  
  void setSelectedPath(String pth) {
      TreePath                        jtp=buildTreePath(new File(pth));
  
      fsTree.setSelectionPath(jtp);
      if(fsTree.getSelectionPath()==null) { fsTree.setSelectionRow(0);       }
      else                                { fsTree.scrollPathToVisible(jtp); }
      }
  
  public TreePath buildTreePath(File dir) {
      ArrayList                           elms=new ArrayList();
  
      do { elms.add(0,dir); } while((dir=dir.getParentFile())!=null);
      elms.add(0,root);
      return new TreePath(elms.toArray(new File[elms.size()]));
      }
