TQt Netscape Plugin Extension

The TQt Netscape Plugin software makes it easy to write browser plugins that can be used on both Unix/Linux and MS-Windows, in Netscape, Mozilla, and any other web browser supporting Netscape's LiveConnect protocol. Modern versions of MSIE do not support this protocol. Use the ActiveTQt Framework to develop plugins for these browsers.

Information

The Netscape Plugin Extension consists of the follow classes:

How-to

  1. Download the Plugin SDK from Netscape, and copy the following files from there to $TQTDIR/extensions/nsplugin/src
  2. Build the Netscape Plugin extension library, found in the extensions/nsplugin/src directory of your TQt 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 TQt 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.

Known Bugs and Limitations

The TQt-based LiveConnect Plugin binding code has a number of bugs and limitations, but is sufficiently stable for many production applications.
