I apologize, I explained what I wanted to say in a bad way
the etext example given in the tutorial does not show a write_file example.
I tried to implement write_file in my application by giving a look at Turtle
art example, adapting it for a custom MIME type. I believe it is quite
simple to do this, but unfortunately, i must have done a mistake in my
- when I give a look at the journal, the screen capture of my save is ok.
But when I try to open it with my application, the picture as been erased
and I have lost all my data (Instead of really opening my save, it starts
from sratch and erase old saves). So I think I misunderstood the
developpment of interaction with the journal. My MIME type is *.gph and
stands for application/x-graph
- when I copy an entry from the journal to the USB key, it has the gph
extension, but it appears as empty : screen capture is a green background
(the standard background of my application). However, when i open it with a
text editor from my linux host, it has text data. So i really think i have
misunderstood the development of interaction with the journal
I apologize for what i've said in my recent post.
