Mission switch from Motif to Qt

• What are the problems with Motif?– Hardly maintainable / customizable– Technologically outdated

• number of developer decrease– ‘old’ look’n’feel– Multiple limitation of the framework– C/C++ mix

• The solution: Switch to a Qt-based version– Large community of developers– Easily customizable– High quantity of built-in tools and

features– C++ based

Scherzo V1 Scherzo V2 Advantages / Improvements

Monolithic architecture

Plugin architecture Capability to deploy some parts Easier modification Simpler cycle of development

Communication with Scherzo server Cleaner behavior (no-freezes while loading) Developers can focus on important parts of

program Less code repetition More centralized into main program Easier to apply global patches

Motif/X11 Qt Complete C++ development Well-known framework Non-dependent to specific version of Linux Less dependent of licenses

X11 look’n’feel CSS customizable interface

Easily customizable interface

N/A Automatic testing feature

Development validation Better V cycle implantation

Validation of text inputs

Validator system Very fast integration for each plugins Pre-made set of validators

Out of date program

Any change done through plugins,

potentially developed

independently

Potential externalization of development Lower development cost

No Security Security by password Capability to require login / password Capability to limit user’s access

Summary of evolution
