Hi guys,
Me again. I'd like my application to link some file as an artwork for a Movie
Type Resource.
The artwork consists in a .png file, stored in some directory (that's not the
important point).
Here is how I "link" the file to the artwork "property" of the Movie Resource
(Python code, but you'll understand) :
***
# self.artwork is a QPixmap containg the artwork.
if not self.artwork.isNull():
# SNIP : saves the cover to `coverpath`.
# `coverpath` is a KUrl instance.
# Build a Resource of type NFO:image from the saved picture :
img = Nepomuk.Resource(coverpath, OntologiesUrls.image())
# "Links" that NFO:image Resource to the NMM:artwork property of my Movie
Resource :
resource.setProperty(OntologiesUrls.artwork(), Nepomuk.Variant(img))
***
The problem is to get the .png file back. Here is what I tried :
***
# Get the Resource linked by the NMM:artwork property :
artwork = resource.property(OntologiesUrls.artwork())
if artwork.isValid():
imgResource = artwork.toResource()
res.artwork = PictureLoader.load_pixmap(imgResource.toFile().url())
***
The problem is that `imgResource.toFile().url()` returns an empty KUrl.
Am I missing something ? What did I misunderstood ? How can I retrieve and load
the linked artwork file ?
Thanks for your help :)
Cheers,
--
François
