Please add command line option for specifying .gtr file.
The content of .gtr file should be consistent with .cdt file, similar to the way it is used now. My understanding is that JTV currently looks for the .gtr file in the same directory where the .cdt file is specified. If the .gtr file is missing, JTV will display the tree without interconnecting branches. This will work fine in almost most cases except the following:
I am trying to open a CDT file in the web client browser connected to a ASP.NET web server. The only way to do this is to use "Response.Redirect(filename.cdt)" function to redirect the web page to the client machine. The brower then makes a local copy of the .CDT file in the "Temporary Internet files" folder in the client machine, and the JTV is lauched with "-r" option to open this local copy. Since there is no .GTR file in the same directory where the .CDT file is, and there is no way to force the JTV to look elsewhere for the original GTR file, there is no tree branches in my display.
(You will NOT see this problem if you just browse to the file and open it manually from the web browser).
