Gaining Acceptance for Qt in the Enterprise
Ricoh - Chris Story, Development Team Manager
Utilizing Qt in a large corporate environment is often fraught with difficulties both practical and political. Upon the creation of a support infrastructure and rapid prototyping group, we were given the task of looking beyond the normal processes, customs, and methods to look for areas where we could achieve better customer satisfaction and expand our markets. Large corporations are often highly political, with centralized engineering and management structures, along with entrenched cultures and standards. Simply making a choice for a new development systemis more about "selling" your ideas to all managers and executives and less about pure technical merits. I will discuss the process, arguments, and strategies we used to push for a move to Qt in a way that will help others who are presenting these arguments in their own organizations.
Christopher Story is the Manager of Service and Infrastructure Development, Global Solutions Engineering at Ricoh. He has been with Ricoh for 12 years, specializing in print output technologies and network management infrastructures. Chris previously served as the companies host output technical lead responsible for integration standards, methods and policies for all non-Windows based systems. Chris has represented Ricoh in many Open Source and standards organizations including the OpenPrinting Workgroup and the IEEE Printer Working Group.
How QtQuick encouraged us to totally rethink a Desktop User Interface
Niels Jeisecke, CTO, saltation GmbH & Co. KG
QWidgets have served us well for a very long time. However new UI paradigms have begun infiltrating the good old desktop world and the limits of QWidgets have started to become quite obvious. Despite or precisely because of its origins in the mobile space QtQuick is the key technology for Qt developers to meet this challenge. This case study is going to illustrate the use of QtQuick in a business oriented application that originally started as a classic QWidget based project but transformed into a purely QtQuick based one during its development. Some code will be shown and a best practices discussion is very welcome.
Nils started his professional life at the age of 12 by programming an animated aquarium on a Sinclair QL. Followed by witnessing the high times of MS-DOS, the wonders of TSR and highmem.sys, University finally unveiled to him that proper multi user operating systems actually exist but they had terrible user interface APIs that usually started with an X or an M. Suddenly some Trolls released a toolkit that started with a Q. This one has now been a focus of his work for more than ten years and he's quite sure that there are more to come. Q is his favorite character (in Bond movies).

Qt and Qt Quick on the Freebox Player set-top box
Free - Arnaud Vrac
Freebox chose to use Qt and Qt Quick early in 2010 to develop the Freebox Player set-top box UI and applications. At this time the Qt Quick technology was still in active development and we took a gamble when we invested our efforts on making this new UI as we did not know if the technology would be accepted by the community and developed further. I will explain the reasons why this gamble on Qt Quick was worth the risk against competing technologies, how we integrated Qt to use the InterlCE platform capabilities using Lighthouse and Wayland, and how we handled the scalability issues inherent to a TV UI.
Arnaud is a software engineer at Freebox, which is the R&D subsidiary of Free, one of the major ISPs in France. He's been working for the last two generations of set-top boxes at Freebox, to leverage the full potential of the hardware of those devices on a Linux kernel. The latest generation set-top box provides Blu-Ray playback, IPTV and DVB-T, local media playback, 3D games, a web browser... All those services were developed and integrated by the Freebox team, allowing us to deliver the most powerful set-top box on the french market yet.
