Thanks for the reply Marek. I have customized it by following the procedure given in Window System API screencast video, wherein we open a topcomponent undock it and fix it to the position we want, close the application and copy the anonymous mode files created in the testuserdir.
I would like to know more about changing the mode container to modified JFrame or JDialogue, coz i have never done it. Is it like creating a JDialogue with a topcomponent inside??
