Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
Trolltech has announced the release of Qt 3.1. New features,
notably the Motif integration, enable a gradual transition path for
single platform applications to the multiplatform world of Qt. This
allows IT professionals to spread investments and resource
requirements over time.
The Qt 3.1 QMotif integration module lets developers insert
Qt-based code into existing Motif applications step by step. QMotif
removes the need to rewrite the entire code base at once and allows
a hybrid application to run during the porting process. In other
words, you can continue with business as usual in terms of current
product development during framework upgrading.
"With the QMotif module we are able to migrate the ASTRIX radio
planning tool to Qt, without rewriting the entire application,"
said Senior Software Engineer Trond Hageseter at Teleplan. "Qt has
been instrumental in the improvement of ASTRIX."
The benefits of this gradual process are reduced down time, ease
of development and a reduced barrier to moving to alternative
platforms--translating into time and cost savings. Once your
applications are fully migrated to Qt, the flexibility and freedom
of platform choice is unrivaled.
"One of the biggest selling points to management was the ability
to use the same code base across Linux, Windows and Mac," says
Software Engineer Phil Brooks of Olympic Medical. "We ported our
basic application to MS Windows in 15 minutes."
ActiveQt, introduced in Qt 3.1, lets developers use the clean,
simple Qt API to write ActiveX servers and controls. ActiveQt is a
simple and efficient manner in which to use ActiveX technology,
facilitating a better integration of Qt with the Windows
environment. When migrating to Qt, developers may keep using parts
of the original MFC application by integrating the ActiveX servers
and controls into the new Qt application, and then gradually port
them to Qt.
Additionally, many improvements are introduced in the Mac OS X
integration simplifying the multiplatform development process even
further. Improvements include integration with the Mac Appearance
Manager, anti-aliased text drawing, user setting and greatly
improved OpenGL support. With Qt 3.1, Qt now supports Mac OS X
v10.2--code named Jaguar--the newest version of the Mac OS.
Qt 3.1 also enables users to implement their own Help Browser
based upon Qt's own Documentation Help Engine, giving Qt users an
up and running framework into which they can insert their own
documentation libraries. Other Qt 3.1 benefits include easier
graphical user interface (GUI) design, enhanced documentation
assistance, improved multi-threading and hundreds of improvements
to the existing class library.
Qt 3.1 is free of charge to open-source developers on
Unix/Linux. Contact email@example.com for conditions, prices and
