Graphics

The New Oxford Dictionary of English defines graphics as:

the products of the graphic arts, especially commercial design or illustration;

the use of diagrams in calculation and design;

visual images produced by computer processing.

the use of computers linked to display screens to generate and manipulate visual images.

IGUANA

Interactive Graphics for User ANAlysis

Main IGUANA focus - interactivedetector and event visualisation:

High- performance 2D/3D graphics;

Graphical user interfaces;

Data browsers.

Integration of other tools, components

The goal is to provide common look and feel for the CMS interactive graphical applications

Interactive analysis is not considered a primary goal. It is assumed that this functionality will be provided by other tools (JAS, Hippodraw, Lizard, ROOT, or OpenScientist)

Qt Toolkit

Ianna.Osborne@cern.ch

Qt ToolkitImplicitly and Explicitly Shared Classes that use reference counting for fast copying.

Input/Output and Networking Classes to provide file input and output along with directory and network handling.

Multimedia Classes that provide support for graphics, sound, animation, etc.

The Qt application framework's underlying object model.

Organizers: splitters, tab bars, button groups, etc.

Plugin Classes.

Template Library: container classes.

Text Related and XML Classes (DOM, SAX)

Threading Classes

Widget Classes

Database related classes, e.g. for SQL databases.

Date and Time Classes for handling date and time.

Drag and Drop Classes dealing with drag and drop and mime type encoding and decoding.

Environment Classes to create and handle events and to provide various global services (event handling, access to system settings,internationalization.

Non-GUI Collection Classes such as list, queue, stack and string, along with other classes that can be used without needing QApplication.

Graphics and Printing Classes to provide drawing (and printing) primitives, including OpenGL and digital image encoding, decoding and manipulation.

Layout Management Classes to handle automatic resizing and moving of widgets, for composing complex dialogs.

Qt Example#include <qapplication.h>#include <qpushbutton.h>#include <qfont.h>

int main( int argc, char **argv ){ QApplication a( argc, argv );

QPushButton quit( "Quit", 0 ); quit.resize( 75, 30 ); quit.setFont( QFont( "Times", 18, QFont::Bold ) );

QObject::connect( &quit, SIGNAL(clicked()), &a, SLOT(quit()) );

a.setMainWidget( &quit ); quit.show(); return a.exec();}

#include <qapplication.h>#include <qpushbutton.h>#include <qfont.h>

int main( int argc, char **argv ){ QApplication a( argc, argv );

QPushButton quit( "Quit", 0 ); quit.resize( 75, 30 ); quit.setFont( QFont( "Times", 18, QFont::Bold ) );

QObject::connect( &quit, SIGNAL(clicked()), &a, SLOT(quit()) );

a.setMainWidget( &quit ); quit.show(); return a.exec();}

Qt Toolkit

Platforms: Qt/Windows is designed for MS Windows 95/98/Me, NT4, 2000 and XP.

Qt/X11 is designed for Linux, Solaris, HP-UX, IRIX, AIX, and many other Unix variants.

Qt/Mac is designed for Apple Mac OS X.Windows

A non-commercial version of Qt/X11 is the de facto standard C++ toolkit for GUI applications on Linux. The KDE desktop environment is based on Qt/X11.

Used by CMS, LHCb, D0, etc.

IGUANA provides a platform that makes it easy to integrate GUIs as a coherent whole, to provide application services and to visualise any application object

Many categories / layers: GUI gadgets & support, application environment, data visualisers, data representation methods, control panels, …

Designed to integrate with and into other applications

Virtually everything is in plug-ins (can still be statically linked)
