Hi,see this code....

Question

hi group,
I am a new user. I am new in Swing also.
Try this code.
when I press keyboard( like a,b,c.....)In my tree I am selecting corresponding nodes.
In keytyped event i have written like this
public void keyTyped(KeyEvent kt)
     this.selectNodeWithValue('A');
private void selectNodeWithValue(char ch)
     DefaultMutableTreeNode root = (DefaultMutableTreeNode)treemodel.getRoot();
     TreePath selPath = null;
     Enumeration enum = root.breadthFirstEnumeration();
     int counter = 0;
     while(enum.hasMoreElements())
          DefaultMutableTreeNode node = (DefaultMutableTreeNode)enum.nextElement();
          String obj = (String)node.getUserObject();
          StringBuffer buf = new StringBuffer(obj);
          if(buf.charAt(0) == ch)
                    TreeNode[] nArr = treemodel.getPathToRoot(node);
                    selPath = new TreePath(nArr);
                    System.out.println("inside selpath is:"+selPath);
     System.out.println("the selpath is:"+selPath);
     getJDestTree().setSelectionPath(selPath);
     getJDestTree().scrollPathToVisible(selPath);
     updateUI();
     if(selPath != null)
          ivjJDestTree.setSelectionPath(selPath);
here just I am checking with one char 'A'.like this I want all the chars.
Any suggestions will be appreciated.

Hi shalini,
you have the key event as parameter.
with this you can get the key char
Eg.KeyEvent Ke
Ke.getKeyChar()..
this will return the key that was pressed.
good luck.
