    Browser plugins

    Hi,

    I'd like to write a simple portable browser plugin for Internet Explorer,
    Netscape and if possible other navigators too. Is there a way to do that
    using Python? For now I'd like to develop something like the GoogleBar, but
    I'd also like to know how to develop "in-frame" plugins such as Flash or
    Realplayer.

    I searched comp.python.com history but all I came across was someone saying
    "why would you want to write Browser Plugins in the first place?". A kind
    of disguised "don't know" if you ask me.
    I then looked on www.python.org but I soon found myself on ActiveX pages: I
    would hate to go that way because it seems neither simple nor portable.

    Any ideas? Any links to documentation for browser plugins development? Any
    code examples or open source project I could check out?

    Thank you very much,
    Aurélien

      I *think* Netscape plugins are quite simple, and it's not possible to
      do things like toolbars without taking over the whole window. I may
      be completely wrong there -- I've never written one. The Mozilla
      documentation is no doubt the place to start (Netscape Navigator is
      now a flavour of Mozilla, in case you don't know). I'm sure Mozilla
      will have lots of more sophisticated ways of doing things, but maybe
      not ones that make it possible to write cross-browser code -- unless
      you write a framework yourself, of course.

      It might not be as bad as it first appears, since XPCOM is heavily
      modelled on MS COM, and was designed to interoperate with it to an
      extent, I believe. PyXPCOM exists (written by Mark Hammond, of
      PythonCOM (etc.) fame). Other starting points:

      -ActiveX Control for Netscape plugins +
      Netscape plugin for ActiveX controls +
      Mozilla ActiveX control (not relevant to your question, but
      interesting)

      I think both Opera and Konqueror support Netscape plugins.


      -Codeweavers sells a product that uses a hacked version of wine to
      allow ActiveX plugins to work in Mozilla, Konqueror, etc. Called
      'Crossover Plugin', or something.


      -Qt has classes for implementing Netscape plugins. At least, it did
      -- can't find it in Qt 3. Not sure if that's accessible from PyQt,
      either. Qt for Windows is not free (but there is a weird
      noncommercial license for a single release of Qt/win 2.x). Qt/win 3
      includes some COM support, so there's a chance that might help you do
      a cross-platform plugin, if you can afford the licence.

      There may well be other ways of doing this, I haven't looked hard.
      Google away...
