KOffice and Qt

KOffice Logo When the KOffice developers ported to Qt 4, it presented them the opportunity to completely redesign the user interface and underlying infrastructure, thereby making KOffice 2 a highly innovative office suite.

Qt has enabled KOffice 2 to run on all major platforms, including Linux (both KDE and Gnome), Maemo, Windows and Mac OS X.

By using Qt's Scribe Classes, the KOffice developers were able to build a mature text renderer which is used consistently throughout the whole suite and adds complete text-editing functionality to every application, including those handling graphic content.

KOffice 2 makes broad use of Dockers (freely drag-able menus) provided by the QDockWidget which contain the specifc toolsets for every editing action the user takes.
