Thank you very much :)<br><br>This time severals instances of activities have their own drawings resumed. :)<br><br>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.<br>

Hello<br><br><div>I come back to this discussion, because there is another obscure point in my mind<br>=> Is it possible to write a file to a usb key, though the tutorial says that there the activity can only acess its data/instance/temp folder ?<br>

Thank you for your answers.<br>But i am not sure i can do my task just with an ObjectChooser. And i need your advices for the strategy i should adopt :<br><ul><li>I want my application to "save a graph" by writing the coordinates in a text file => i am conviced that for this tasks, i should use the folder data of the activity</li>
<li>i want my application to "load a graph" from a previously recorded graph<br></li><li>but i also want the users to share other graphs each others : more precisely, for users who don't have internet access (or for later systems restores, maybe after a crash, for example) to be able to import files from a usb key</li>
</ul>So, what is the best strategy in order to do these tasks and remain conform to Sugar best practices ?<br></blockquote></div><div><br>In general, using the Journal for these sorts of tasks is best practice in Sugar. You can set a file path with your data associated with your activity's datastore instance. That file can contain anything you want. It is typical to have a method that overrides the builtin write_file method -- called whenever the activity is either removed from the foreground or the activity exits -- from which you save data.<br>
<br> def write_file(self, file_path):<br> ''' Write the project to the Journal. '''<br> ...<br><br>You can also set the mime type for this file, so as giving a hint as to what activities can subsequently open it.<br>
<br>Lots of examples of this out there.<br><br>-walter<br><br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204, 204, 204);padding-left:1ex"><div><br>Regards<div>
