I have constructed empty tree. when ever if i click add button then only tree should visible without root.I have used tree.setrootVisible(false).But its not working for my code.I am trying add one node only.If i try to add one more node i can able to get add for that method. For add button i added actinlistener.there when ever i click add button i am getting data from textfield(textfield.gettext()) like that. I can collect only one data from,next time if click i am getting data.But i cant able add that text to tree as a next root.
