1) CERN, PH-SFT – European Organization for Nuclear Research, Geneva, Switzerland; JINR – Joint Institute for Nuclear Research, Dubna, Russian Federation.

The ROOT’s GUI classes support an extensive and rich set of widgets. These widget classes interface to the underlying graphics system and OS via abstract classes - TVirtualX and TSystem. Concrete versions were

implemented for X11/*nix, Win32, Qt and now Mac OS X:

ROOT GUI framework (windows/widgets/controls classes)

ROOT GUI applications (browsers, canvases, treeplayers, event displays) and user GUI applications

Abstraction layer: TSystem, TVirtualX

TMacOSXSystem: event handling/dispatch (mouse/keyboard/geometry change/repaint events, I/O

activity, etc.)

TGCocoa/TGQuartz: 2D/3D graphics (graphical “back-end”), window management, font management,

cursors, drag and drop, etc.

New graphical back-end for Mac OS X:

•is a complete implementation of TVirtualX interface;•uses native APIs directly, no external X11-server application (XQuartz) required;•2D graphics – font, line, polygon anti-aliasing;•2D graphics – transparency and gradients;•“Retina-friendly”;•can mix with native GUI-controls (Apple’s Aqua UI)•in future can support multi-threaded GUI;•implemented in Objective-C++.

Components (implementation):

•Window manager uses Apple’s Cocoa framework (object oriented framework written in Obj-C) and Apple’s Quartz Window Server API.•I/O activity, GUI events, event loop - based on Cocoa and Apple’s Core Foundation framework•“Event translator” – translates native GUI events into “X11-like” events/emulates X11 events (X11 events required by ROOT’s GUI to work)•2D graphics – implemented with Apple’s Quartz 2D API, Core Image and Core Text frameworks•3D graphics (OpenGL): window/context/pixel format management – Cocoa framework.

Availability:

•Needs Mac OS X >= 10.7;•XCode >= 4.x (Apple-provided clang version >= 4.2);•Part of ROOT v. 5-34 (--enable-cocoa configure option)•Default in the trunk version.

Standard ROOT GUI fully implemented with Cocoa

Parallel coordinates withtransparent lines

No transparency

Alpha = 0.01

New color gradient fill

Transparent objects
