There is no simple call for it, but all the ingredients for it is there.

Start by looking at:

GAppInfo *g_app_info_get_default_for_uri_scheme  (const char *uri_scheme);

(uri scheme comes from g_file_get_uri_scheme())

If that returns NULL, we must look at the file type, which is done with:

g_file_query_info() or g_file_query_info_async()

(passing G_FILE_ATTRIBUTE_STD_CONTENT_TYPE as attribute)

Then you can get the default from:

GAppInfo *g_app_info_get_default_for_type (const char  *content_type,
					   gboolean     must_support_uris);

Clearly these could all go into a helper function:

GAppInfo *g_file_get_default_handler (GFile *file, 
                                      GCancellable, *cancellable, 
                                      GError **error)

Patches accepted.

Then you can launch the GAppInfo using g_app_info_launch(). 

For certain features (startup notification, starting on right screen)
you can also pass in a GAppLaunchContext implementation. This is a bit
tricky atm, but in the future such an implementation will be availible
in Gtk+ for simple use.
