The QtBrowserPlugin solution is useful for implementing plugins for web browser.

The project provides a framework that makes it simple to export widgets and objects as plugins for web browsers supporting the Netscape LiveConnect APIs.

Supported web browsers are Netscape, Mozilla FireFox and Opera. Internet Explorer is supported when the plugin supports ActiveX via ActiveQt.

Required Libraries:

QtCore, QtGui

Please refer to the Qt Editions Comparison Chart for which Qt products include these libraries.

Documentation:

• QtNPBindable
• QtNPFactory

• A trivial "Hello, World" plugin.
