Hi, Let me make my problem more clear. I have a main frame, which has a internal frame. In that internal frame i have a jtree. Now when i click on the node of the jtree, i can update the title of the internal frame. I can reflect in the title , the node i have clicked. Now i need to do this on the main frame. I assume i need to listen to the jinternalframe state. Since i need to dynamically change the title of the main frame as the title of the internal frame changes. Can u help me in this regard. Regards, Prav_ford.
