Qt-based LiveConnect Plugins

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, e.g. by editing Apache's mime.types file. If the files are viewed via a //... 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.
