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

Apologizes if my question is too evident and unusefull . But i don't feel yet ready for developping serailisation/sharing part of my app No apology necessary. Than you The standard way to share to removable media in Sugar is to simply save as usual to the Journal. From the Journal, there are mechanisms for copying files to USB (and soon, $HOME/Documents and a remote server). Argh : perhaps i saved my file badly from the application to the journal because (though i surcharged the method write_file of activity.activity) - in the journal (in its lits form, not graphical one) i can't see any trace of saves in the dropdown menu, though i clicked on the activity keep button - maybe i did not use the journal in the good way, or it's because i did not coded the algorithm well All changes have been made in the learning writing gitorious. - Launcher is the class inherited from activity.activity - TheDrawingAreaEventBox is the class which define the canvas, and in which i defined the serialization to the Journal Could someone have a look at my code and say if i bad coded the serialization please ?

Then, to open the file in an activity, the activity must have registered interest in the MIME type of the file, and so the open entry dialog will contain the activity name as an option.

Re: [Sugar-devel] Should or should not i use PyGTK = 2.4 widget ?
Laurent, Gonzalo is correct about ObjectChooser. If you actually do want to have read-only access to the file system, not the Journal, than any version of Sugar from .82 on up should allow you to use a FileChooser. I use one in a couple of my Activities: Sugar Commander and Read SD Comics, and both have been tested on Sugar .82 and later.
