How to communicate with Netscape Navigator?

L.S.

I would like to send from within a Tcl interpreter a command to an
already launched instance of Netscape Navigator to make it fetch a URL
from within Tk.
Would such a thing be possible? If so, I'd appreciate
very much a pointer to further particulars.

Please note that I know how to launch a *new instance* of Netscape
Navigator to let it fetch a URL. My question specifically adresses an
already running process of Netscape Navigator.

I would like to be able to do this under Linux, as well as Windows.

Thanks in advance for any help,

Erik Leunissen

netscape has capabilities for this already. On Windows, you can talk
to it with DDE (use the built-in Tcl dde package), and on Unix IIRC
you exec netscape with the -remote flag, and it tries to use an
existing instance if it finds one.

$ netscape -?

...
-remote <remote-command> to execute a command in an already-running
Netscape process. For more info, see

Yes, it does, eventually. There is a Tcl-extension that does the same
thing (communicating with Netscape using X Window Properties) without
starting another instance of Netscape, which works much faster (almost
instantly and without any overhead). I haven't tried it with recent
versions of Tcl/Tk, though.

According to Jochem Huhmann <j...@gmx.net>:

I have used it with older versions of Tcl/Tk and older versions of Netscape.
I don't know if it still works with Netscape 6/7 though.
