hi,
I have the following code which compiles and runs successfully,however no
matter what uri I choose I always get the error “There was an error creating
the snapshot”. I would please request you to point out the problem with this
code.
Please note that in order to run this code you need to provide a uri argument
to webkit_web_view_load_uri.
I would have not posted this here but I could not find any coding samples or
additional documentation available on said topic, other than the API docs.
thanks.
