Hello !
Like I guessed, the call of edje_cc was ugly as hell. Never mind, I made a
working version with the evas librairy. The reloading function is great, but
does it check if the file have been changed before reloading, or do we have
to do it manually in order to optimize the code?
Anyway, good tip, thanks. It simplified the code a lot.
Only one question left : is there any evas function enabling us to resize
dynamically the evas_object in order to fit the container? Like edje does
;).
Currently, when my picture is smaller than the module, we just see a piece
of it. When we enlarge the module more than the size of the picture, we find
the same image, over and over, like a mosaic. Odd.
For those who still wonder, the "freeze" was my fault, I forgot some
important part in the edc file and the mouse events didn't worked well. The
fact that the image didn't change was caused by the edje_object_file_set
which doesn't seem to reload the edj when it's the same file that has
already been loaded in the object (even if this file was recompiled in the
meantime).
Once again, thank you very much for helping us.
Jean Creusefond and Quentin Gibeaux.
