Description
ROOT as a scientific data analysis framework provides a large selection data
presentation objects and utilities. The graphical capabilities of ROOT range from 2D
primitives to various plots, histograms, and 3D graphical objects. Its object-
oriented design and developments offer considerable benefits for developing object-
oriented user interfaces. The ROOT GUI classes support an extensive and rich set of
widgets that allow an easy way to develop cross-platform GUI applications with a
common look and feel. The object-oriented, event-driven programming model supports
the modern signals/slots communication mechanism. This mechanism is an advanced
object communication concept; it largely replaces the concept of callback functions
to handle actions in GUIs. Signals and slots are just like any object-oriented
methods implemented in C++. It uses ROOT dictionary information and CINT interpreter
to connect signals to slots in ROOT. The progress of the recent user interface
developments in ROOT are presented in this paper.
