Qt and Coin is a perfect match since they are both open source, widely
portable and easy to use. Quarter has evolved from Kongsberg SIM's
own experiences using Coin and Qt together in our applications.

The functionality in Quarter revolves around QuarterWidget, a subclass
of QGLWidget. This widget provides functionality for rendering of Coin
scenegraphs and translation of QEvents into SoEvents. Using this
widget is as easy as using any other QWidget.

Quarter also comes with a plugin for Qt Designer, Nokia's tool for
designing and building GUIs. Once you install Quarter, the
QuarterWidget becomes accessible in Qt Designer, and you can include
it in the user interfaces you create. The plugin facility also
provides you with the capability of dynamically loading ui files
containing a QuarterWidget in your application.

By using Coin, Qt and Quarter to build your 3D graphics applications,
you have the power to write software that is portable across the whole
range of UNIX, Linux, Microsoft Windows and Mac OS X operating
systems, from a 100% common codebase.

This release works with the latest version of Coin (3.0).


Enjoy,
The Quarter Team
