Guidelines

Information for Students

These ideas were contributed by our developers and users. They are sometimes vague or incomplete. If you wish to submit a proposal based on these ideas, you may wish to contact the developers and find out more about the particular suggestion you're looking at.

Being accepted as a Google Summer of Code student is quite competitive. Accepted students typically have thoroughly researched the technologies of their proposed project and have been in frequent contact with potential mentors. Simply copying and pasting an idea here will not work. On the other hand, creating a completely new idea without first consulting potential mentors is unlikely to work out.

When writing your proposal or asking for help from the general KDE community don't assume people are familiar with the ideas here. KDE is really big!

If there is no specific contact given you can ask questions on the general KDE development list kde-devel@kde.org. See the KDE mailing lists page for information on available mailing lists and how to subscribe.

Project: Tomahawk features in Amarok

Brief explanation: Tomahawk is a cross platform, open source social media player that allows users to share music seamlessly and listen to it anytime, anywhere. The goal of this project is to implement the same features in Amarok and maintain compatibility with Tomahawk

Expected results: Implement a service in Amarok that allows users to share their music files with online friends and allows them to listen to the tracks via stream

Knowledge Prerequisite: Qt/KDE development(includes C++ and git), streaming

Mentor: Bart Cerneels

digiKam

digiKam is an advanced digital photo management application for Linux, Windows, and Mac-OSX.

digiKam project web site - Mailinglist - Google+ page - IRC channel: #digikam on Freenode

Project: Camera User Interface Revamp

Brief explanation: digiKam features a graphical interface to access and download pictures from digital cameras. Code is rather old, using Qt3Support classes for the icon view, the UI code intermangled deeply with backend code, and has not seen very much care and love for some years.

This project would involve taking the old code apart, rewriting a clean code base backend and front-end, but also adding user interface elements to make the most important everyday task as easy as possible.

In more detail: Write a model listing images on a camera (There are two backends, USB mass storage cameras, which are basically files on disk, and GPhoto2 cameras, which require access through a library). Take the existing digikam icon view and delegate classes, which are prepared for code re-use, and put together an icon view for the model. Cleanly separate the code that does the actual work (downloading, converting, renaming) from the UI. Wrap that in the main window.

User Interface design: the current one is powerful, exposing many options. We want to preserve that. But at the same time, there are three very common actions: a) Download all new files to the last used album b) Download all new files to a new album c) Download all new files to an existing album.

It should be possible to carry out task (a) with one click, task (b) and (c) with two or three clicks, without opening a dialog. Friendly to the new user, preserving access to all options for the poweruser.

There also the technical TODO list relevant of this project

Expected results: A camera user interface based on a pure Qt4 model/view and a cleaned code which provides the currently available features, offering a quick path to download new pictures.

Knowledge Prerequisite: Qt, C++. Interest in Qt model/view and User Interface code.

Mentor: Gilles Caulier

Project: Native MacOSX support

Brief explanation:

digiKam needs to be available under MacOSX in native. Currently, - Macports project is the only way to get last digiKam under Apple computers. Macports require to compile all depencies and digiKam as well. It's a long and hazardous solution to see digiKam running under Mac.

Also, current digiKam implementation is not optimized for Mac desktop. A lots of point need to be improved to support better this operating system. Graphical interface need to polished.

See relevant entries in KDE bugzilla about MacOSX support :

257679 257773

Expected results: Provide scripts and configurations to build automatically a DMG archive of digiKam for MacOSX. Improve digiKam GUI everywhere to be more elegant and more optimized for MacOSX.

Knowledge Prerequisite: C++, Qt, MacOSX, scripting, DMG, packaging

Mentor: Gilles Caulier


Project: Video metadata support

Brief explanation:

All recent digital-still camera devices provide video capture. digiKam must be able to manage these files as it do with images. digiKam can already play-back video and register files to the database, but it lack important metadata used to catalog and sort items (as date, camera name, and all record conditions).

To improve video files support, video metadata management done in background need to be improved, to patch Exiv2 shared library, already used by digiKam for photo metadata handling.

See relevant entries in KDE bugzilla about video support :

164442 229543

Expected results: Add video files support to Exiv2. Patch digiKam metadata interface to handle video information.

Knowledge Prerequisite: C++, Qt, video format, metadata

Mentor: Gilles Caulier and Andreas Huggel


Project: Clone Tool for Image Editor

Brief explanation:

In digiKam image editor we need a simple clone tool to be able to remove quickly dusts, spots, and other unwanted artefact from an image.

See relevant entry in KDE bugzilla about it :

132483

Expected results: add a new tool (as new image editor plugin) with the clone feature.

Knowledge Prerequisite: C++, Qt

Mentor: Gilles Caulier or Marcel Wiesweg


Project: Video Slideshow Generator

Brief explanation: In digiKam image editor we need a new tool to export images as video slideshow.

See relevant entry in KDE bugzilla about it :

Project: Focus tracking in KWin and KMagnifier

Brief explanation: Currently the KWin zoom plugin and KMagnifier implement focus tracking using KAccessible. KAccessible uses QAccessible direct to implement focus-tracking. The problem with that is that it only works for Qt/KDE applications. The plan is to change the existing code in the KWin zoom-plugin and KMagnifier to not use KAccessible any longer to fetch the information what application/widget/etc has the focus but to use dbus to connect with AT-SPI2 and fetch all needed informations (means the x/y-coordinates where the focus is atm) from there.

Once done and if we do not lose to much time with unexpected problems there should be enough time left to look at common applications like KWrite, Kate, Konsole, Dolphin, etc. to identify and fix cases where the applications are not sending the proper QAccessible::Focus events so that focus-tracking doesn't work there. See for example the fix I did back then to enable focus-tracking in KWrite/Kate - note that all Qt-widgets and most KDE-widgets are already fine and accessible but that a custom canvas like KWrite/Kate are using them to draw the text are basically not accessible at all what is why the patch introduces new classes to make the canvas accessible including making focus-tracking working.

Expected results:

  • The KWin zoom-plugin and KMagnifier are using ATSPI2 rather then KAccessible to implement focus-tracking.
  • Focus-tracking within KDE works for Qt/KDE applications like it does today with KAccessible (or even better :-) ) and applications using other Toolkits (e.g. GEdit, Firefox and LibreOffice.org) will work too.

Knowledge Prerequisite: C++/Qt

Mentor: Sebastian Sauer <mail@dipe.org>

Project: Screen reader friendly KDE applications

Brief explanation: With Qt at-spi we now have a solution to make KDE applications work with the Orca screen reader from Gnome.

This project is about reaching out to screen reader users in order to find out how to make KDE applications work better with the screen reader. Along with the research is always the writing of patches to implement the findings. This requires good communication skills and some C++ knowledge.

See also:

Expected results:

  • Improved experience for users that use a screen reader
  • Many small patches in order to emit the right signals to the accessibility framework
  • Implementation of QAccessibleInterfaces for custom widgets used in KDE

Knowledge Prerequisite:

  • C++/Qt
  • Python is a bonus as it will make understanding Orca easier
  • Reading code - you will look at code from many different applications and try to fix small issues there
  • Build applications, kdelibs and Qt

Mentor: Frederik Gladhorn <gladhorn@kde.org>


Project: Plasma Accessibility

Brief explanation: Making it possible to use Plasma with a screen reader is the goal of this project. You will have to dive into Plasma in both KDE libs and the desktop shell. It will be necessary to make sure keyboard navigation works and feedback from individual parts of the desktop is good so that the screen reader can make sense of it. This might include working on the screen reader to improve the experience.

See also:

Expected results:

  • A Plasma desktop that is usable for people that rely on a screen reader
  • Implementation of QAccessibleInterface where it makes sense
  • Accessible plasma widgets (krunner, application launcher, systray, panel etc)

Knowledge Prerequisite:

  • C++/Qt
  • Python is a bonus as it will make understanding Orca easier
  • Build Plasma and run it with custom built kdelibs and Qt
