Editing Calligra (section)

== Technical details ==
Calligra is written with dependencies on [[KDE Frameworks]] 6 and [[Qt (software)|Qt]] 6. Older versions depend on KDE Frameworks 5/Qt5, [[KDE Platform 4]] and Qt 4, and even older versions of KOffice depend on [[KDElibs]] and Qt 3. Despite that Calligra Suite is released independently of the [[KDE Software Compilation]] or of the [[KDE Applications]].

All components of the Calligra Suite are released under [[free software license]]s and use [[OpenDocument]] as their native file format when applicable.

The developers of Calligra plan to share as much infrastructure as possible between applications to reduce bugs and improve the user experience.<ref>{{cite web|url=http://www.koffice.org/announcements/announce-2.0alpha5.php|title=KOffice 2.0 Alpha 5 Release Announcement|date=21 November 2007|archive-url=https://web.archive.org/web/20081011051340/http://koffice.org/announcements/announce-2.0alpha5.php|archive-date=11 October 2008|url-status=dead}}</ref> This is done by common technologies like [[Flake (KDE)|Flake]] and [[Pigment (KDE)|Pigment]]. Flake provides a way to handle shapes, which can contain text, images, formulas (via [[KFormula]]), charts (via [[KChart]]) or other objects, in a consistent way across all applications. The Calligra team also wants to create an OpenDocument library for use in other KDE applications that will allow developers to easily add support for reading and outputting OpenDocument files to their applications.<ref>{{cite web|url=http://dot.kde.org/1179144063/|title=KOffice ODF Sprint Report|work=KDE.news|date=14 May 2007|access-date=23 January 2008|archive-date=13 May 2008|archive-url=https://web.archive.org/web/20080513062403/http://dot.kde.org/1179144063/|url-status=live}}</ref> Automating tasks and extending the suite with custom functionality can be done with [[D-Bus]]. Previously it was possible to also use scripting languages like [[Python (programming language)|Python]], [[Ruby (programming language)|Ruby]], and [[JavaScript]] through the [[Kross (KDE)|Kross]] scripting framework.
