Calligra/Calligra Mobile

From KDE Community Wiki

See also: Kexi Mobile. and: FreOffice Blog

Calligra Mobile is a mobile user interaction of Calligra Suite. The calligra mobile code base is under tools directory in Calligra trunk. The source code for Harmattan office (a different UI based on Calligra) can be downloaded here.

Plan

One of the key goal in Calligra Mobile development is to make it end user ready (as mobile clients in Maemo, MeeGo, etc, environments). This basically means that it would require atleast the following key improvements:

  • Clean up the code architecturally and make it clean and modular (Already being actively developed by Mani and Jaroslaw and more)
  • Ensure there are no crashes in the UI and software is stable
  • Make the mobile office stable and address some of the usability issues identified by the analysis made so far
  • Identify and Document the APIs required to use Calligra backend and agree these to be become API Calligra suite will provide
  • Agree if we should merge the IRC channel(currently #FreOffice @ Freenode) or just keep the mobile stream and desktop discussions parallel
  • Clean up the UI plug-in architecture and make the current plug-ins stable and utilize only stable plugins for the next release
  • Update the software based on end user feedback and improve usability issues which are stopping from using the FreOffice for real world use cases
  • For Maemo 5 move the application from development edition to end user ready version and get real users to use
  • For MeeGo environment Move the current Qt version of FreOffice on Maemo 5 with minimal updates and repackaging into MeeGo platform 1.2 (Under development)
  • Later plan to enhance the UI by developing QML based UI for MeeGo Platform and contribute as a reference implementation for Office viewer there
  • In future: MeeGo has multiple Ux environments and we would like to enhance the Mobile Ux to scalable to other ux if time permits.
