Note : by default, QxEntityEditor application is limited to 5 entities per project. To get a license key and create unlimited entities per project, please contact us using this e-mail : contact@qxorm.com. A video presentation of QxEntityEditor application is available. Price of a QxEntityEditor license : 300€ (per developer, 12 months of free updates). Before you install and compile QxOrm, you need the following libraries : boost (from version 1.38) and Qt (from version 4.5.0) :
| boost : many of boost's founders are on the C++ standard committee and several boost libraries have been accepted for incorporation into C++1x (new standard for the C++ programming language). The boost's libraries are aimed at a wide range of C++ users and application domains. QxOrm uses the following features of boost : smart_pointer, serialization, type_traits, multi_index_container, unordered_container, any, tuple, foreach, function. It is recommended to install the latest version of boost available at the following address : http://www.boost.org/
| Qt : cross-platform application development framework : ihm (QtGui), network (QtNetwork), xml (QtXml), database (QtSql)... Qt provides excellent support and documentation. Using Qt, you can write simple and powerful C++ code. Qt is produced by Digia's Qt Development Frameworks division and is available under LGPL license. QxOrm is compatible with a lot of Qt's objects : QObject, QString, QDate, QTime, QDateTime, QList, QHash, QSharedPointer, QScopedPointer... It is recommended to install the latest version of Qt available at the following address : http://qt.digia.com/
