Qt Quick Migration status

Porting guidelines

First you should consider the Gtk+ activity as an example, not as a something we want to clone exactly. You are encouraged to improve the original version, either from a user experience stand point and on the educational value.

Think about adding animations where necessary. It was hard to do in Gtk+ and its very easy in QML.

One important part of the work is to make the activity resolution independent (including support for vertical and horizontal layout).

Images

The preferred image format is svg. A valuable resource for images is openclipart.org. To edit svg image you can use the excellent vector graphic editor Inkscape. In the GCompris Gtk+ version many images are already in svg but not all. I created an archive of all the svg images I have, maybe the one you miss is in it.

Core

If you are interested in working on a core feature of the Qt Quick version of GCompris, Edit this page and put your name to be sure you are alone on this task.

Description	Status	Developer
Make install	In progress	Johnny
Packaging for each platform	In progress	Thib and Cyril
Admin mode etc., cf. Administration design	In progress	Bruno / Holger
Dataset handling	TBD
Ability to globaly change letter spacing, word spacing and line spacing. Especially usefull to help children to read (font size change is already implemented).	TBD
Adding a search feature for activities in the menu (as we now have a lot of activities, it is hard sometimes to find a specific one)	TBD
In the Gtk+ version we had background musics. Some people miss them on the new version. We should keep this as an optional download	TBD
Ability to anonymously track usage especially activity used. We don't want to rely on a proprietary system and it must work on all platform. One option is to install a Piwik instance on gcompris.net. This tool can be used to track in app usage.	-	-
Port our Manual from Wiki to Docbook (managed in our git) and adapt its content from the Gtk+ version to the Qt one	in progress	Patch provided by Burkhard Lück
Add documentation towards activity developers. The documentation must be in Doxygen format as expected by KDE	in progress	Holger
On Android distribute voices in an APK Expansion File	-	-
Persist the levels that have been completed for each activity and report a progress feedback in the activity icon. Add an option to save it to disk (best for home) or not (best for schools)	-	-
Add a page for GCompris in https://edu.kde.org/applications/	In progress	Burkhard Lück

Bug Tracking

Here is a list of identified bugs and improvements we would like to complete before the initial release.

Activity	Description	Status	Developer
click_and_draw	Find a way to have less distortion in images in portait mode
click_on_letter: multi-char support	Make letters in click_on_letter datasets strings instead of single characters, as needed by some locales.
No sound on Windows	Need to find an audio format supported by default on Windows
gletters, wordsgame, Wordlist	Let the translator provide the keyboard letter order in the dataset and maintain it in Wordlist

Activities

If you are interested in porting an existing activity to the Qt Quick version of GCompris, Edit this page and put your name to be sure you are alone on this task. A star (*) in the front of the name indicates that this activity is mandatory to consider the Qt version as a replacement of the Gtk+ version, other are less important.
