Qt-based LiveConnect Plugins

Qt-based LiveConnect Plugins for Netscape and Explorer


The Qt-based Netscape Plugin software makes it easy to write plugins such that they can be used on both Unix/Linux and Windows/95/NT, in the Netscape and MS-Explorer, and any other WWW browser supporting the same protocol.

How-to

  1. Download the Plugin SDK from Netscape, and copy the following files from there to $QTDIR/extensions/nsplugin/src :
    • common/npwin.cpp
    • common/npunix.c
    • include/npapi.h
    • include/npupp.h
    • include/jri.h
    • include/jri_md.h
    • include/jritypes.h
  2. Build the Netscape Plugin extension library, found in the extensions/nsplugin/src directory of your Qt distribution. This produces a static library to be linked with your plugin code.
  3. Read the plugin class documentation, and examine the example plugins.
  4. Do most of your development as a stand-alone Qt application - debugging Netscape Plugins is cumbersome. You may want to use signal(2) in your plugin to enable core-dumps if your browser disables them.
  5. Note the platform-specific build steps below.
  6. Read about the raw plugin interface in Netscape's handbook.
  7. If files viewed by a plugin are provided by an HTTP server (using a http://... URL) then the server must be configured to send the correct MIME type for the file, such as by editing the mime.types file of Apache. If the files are viewed via a file://... URL, then the browser will use the filename extension to decide the file type (and hence the plugin to load) - the user may need to set the filename extension in the Helpers or Applications section of their browser preferences.

We are working on streamlining the build process for Qt-based Netscape Plugins.

Known Bugs

The Qt-based LiveConnect Plugin binding code has a number of minor bugs, but is sufficiently stable for most production applications. All of these have known solutions which we are working to implement.
