Documentation of the Qt Quick Version (Under development)

This is a new version of GCompris based on the Qt Quick technology. Our users expect us to deliver a version that runs on Desktop and on Tablets. Sadly with the Gtk+ version these was no easy way to achieve this. The decision has been taken to rewrite completely GCompris on a new framework. This is a departure from the Gtk+ development framework that was based on the C and the Python language. Now the development will be done with a mix of QML, JavaScript and C++.

The rewrite will not happen overnight and we need your help. If you are interesting in discovering the Qt Quick technology while doing something useful, you can do the port of a GCompris activity.

New contributor

You must follow the coding guidelines described in those links:

Qt Quick development process#Coding guidelines

GSOC newcomers#Code quality

If you want to develop a new activity for GCompris, a good start is to follow the instructions on this page : An exercise for new contributors.

Always look at existing activities, and take a look at their code when you have a problem. You have to think by yourself, try and fail to find solutions. This is not a school assessment.

We can only provide limited feedback to get you started.

If you want to create a new activity, you will need to develop it by yourself. Think about making a detailed mockup, that will help you solve the main design questions, and make it easier to communicate the idea. Then, once the mockup is accepted, of course you will have to work on it. When you have a prototype of the activity almost working, then we can provide a little more help if needed.

For the graphics, if you can, try to follow the artwork guidelines. In any case, once an activity is ready, the images have to be checked and updated by our main artist.

Please use the mailing list to share your thoughts, issues, and wishes to our community.

Note: If you plan to apply for next GSoC, please check GSOC newcomers, and especially the last paragraph.



Translations are managed by the KDE translation teams. If you would like to participate in the translation of GCompris you must contact the KDE translation team you want to participate in.
