[Sugar-devel] Should or should not i use PyGTK >= 2.4 widget ?

[laurent bernabe]

Thank you very much :)

This time severals instances of activities have their own drawings resumed.
:)

But is it possible to, from the journal interface, see the generated file
for a particular instance, so that i can transfer it to a folder, a usb key
(and so on ...) ? Because i would like children to be able to import easily
"graphs" files or "graphs" zip archives.
