Re: GtkApplication Thread Initialization

[Tristan Van Berkom <tvb gnome org>]

The answer is that it depends on what versions you have, I think though
that GApplication comes from a version of glib with threading
automatically initialized ?

Not sure, in some code that I need to compile with various versions I have
code setup like this:

gint
main (gint argc, gchar *argv[])
{
  /* Initialize threading in older libraries */
#if (!GLIB_CHECK_VERSION (2, 31, 0))
  g_thread_init (NULL);
#endif

#if (!CLUTTER_CHECK_VERSION (1, 9, 0))
  clutter_threads_init ();
#endif

.....

That's what I had in place for clutter (and the above works
for me... it might be accurate and might not), ... I'm quite certain
that for modern versions of GTK+ the gdk thread lock is
ensured by calling gtk_init() somewhere... not sure since which
version though...

Cheers,
           -Tristan
