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.
