I'll explain this at some point:

    package require tcom
    wm overrideredirect . on
    pack [canvas .c -background blue -height 20 -width 20]

    proc paste_on_top_IE toplevel {
        set application [::tcom::ref getactiveobject \
                             InternetExplorer.Application]
        wm geometry . +[$application Left]+[$application Top]
        raise .
        update idletasks
        after 300 [list paste_on_top_IE $toplevel]
    }

    paste_on_top_IE .

Notice the use made of tcom.

[Eventually explain Browser Helper Objects, XUL, toolbar SDK, ...]


Communication with an existing browser instance, as opposed to invoking browsers:

  • windows: netscape (and other browsers) respond to a few DDE commands.
  • unix:
    • netscape: recognizes a -remote flag that attempts to re-use an existing browser process, or you can communicate with netscape on unix without the -remote flag with an extension[L1 ] [L2 ]:
    • konqueror: in KDE you can make use of the "kfmclient" command (type "kfmclient --commands" for reference).

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.
