GSoC/2012/Ideas - KDE Community Wiki

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 [email protected]. See the KDE mailing lists page for information on available mailing lists and how to subscribe.

KDE Accessibility

The KDE Accessibility subproject aims to make KDE applications accessible for all.

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 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.

http://blogs.kde.org/node/4287 describes our current solution for focus-tracking
http://community.kde.org/Accessibility/qt-atspi describes how to setup your environment to get ATSPI2 and Qt working together using the Qt-ATSPI bridge.
See the linked source-code above and grep there for "focusChanged"

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) will work too.
