Opening Browse programatically

[Joshua Minor]

Thanks.  It works now.  In case anyone else wants to do this, here's  
what I ended up with:

     def open_url(self, url):
         """Ask the journal to open an URL for us."""
         from sugar import profile
         from shutil import rmtree
         from sugar.datastore import datastore
         from sugar.activity.activity import show_object_in_journal
         from tempfile import mkdtemp
         tmpfolder = mkdtemp('.tmp', 'url',  
os.path.join(self.get_activity_root(), 'instance'))
         tmpfilepath = os.path.join(tmpfolder, 'url')
         try:
             tmpfile = open(tmpfilepath, 'w')
             tmpfile.write(url)
             tmpfile.close()
             os.chmod(tmpfolder, 0755)
             os.chmod(tmpfilepath, 0755)
             jobject = datastore.create()
             metadata = {
                 'title': url,
                 'title_set_by_user': '1',
                 'buddies': '',
                 'preview': '',
                 'icon-color': profile.get_color().to_string(),
                 'mime_type': 'text/uri-list',
             }
             for k, v in metadata.items():
                 jobject.metadata[k] = v # the dict.update method is  
missing =(
             jobject.file_path = tmpfilepath
             datastore.write(jobject)
             show_object_in_journal(jobject.object_id)
             jobject.destroy()
         finally:
             rmtree(tmpfilepath, ignore_errors=True) # clean up!
