Bridging XPCOM/Bonobo -- techniques

Uche Ogbuji (uche.ogbuji@fourthought.com), Author
Uche Ogbuji is a computer engineer, co-founder and principal consultant at Fourthought, Inc. He has worked with XML for several years, co-developing 4Suite , a library of open-source tools for XML development in Python. He writes articles on XML for IBM developerWorks, LinuxWorld, SunWorld and XML.com. Mr. Ogbuji is a Nigerian immigrant living in Boulder, CO.

Summary:  XPCOM and Bonobo are two popular component technologies. Cross Platform Component Object Model (XPCOM) is the component system for customizing and extending the Mozilla browser. Bonobo is the component model of the GNOME project: a popular desktop environment for Linux and other UNIX operating systems. This article presents techniques for bridging the two component models. It presents a bare-bones bridge between the two systems on which projects can be built that share components. It provides a few examples of applets that illustrate embedding GNOME controls in Mozilla and vice-versa.

Tutorial introduction

Who should take this tutorial?

This tutorial presents an example of how a developer can build an adapter and static bridge from XPCOM (particularly within Mozilla) and the GNOME Bonobo component system. If you need to use components across environments, the techniques presented in this tutorial will be useful.

Component bridging can be used to embed or access controls from one system to another. For instance, component bridging allows you to embed a file manipulation control from Bonobo into Mozilla. It can also be used to take advantage of complex behavior that has been implemented in another system.

Prerequisites

You should be familiar with either CORBA or COM, preferably both. The code is written in C and C++. Familiarity with Bonobo is important, but the basic introductions listed in the Resources section should suffice.
