Cross-platform approach to create the interactive applications based on ROOT and Qt GUI libraries

This paper presents the approach and an implementation of the Qt-based low-level graphical plug-in of the ROOT package. In spite of other existing implementations, this work uniquely allows to create applications which can seamlessly use the ROOT GUI classes as well as the Qt Widgets. rrent code can be built from a single ROOT-base package and can be assembled for both Unix and Windows OS. No alteration of either user code or core ROOT code is required. mple application using this approach is also presented.
