[GNUnet-developers] [Windows] gnunet-gtk

gnunet-gtk has display problems under Windows.
This is because GTK doesn't behave well with multi-threaded applications.
gtk_window_new and _destroy only work from within the main thread.
A workaround is to let the GTK main-loop call a callback function which does
the actual GTK work. It would look like that:
--- helper.c
gint doGuiMessage(char *note)

void guiMessage(const char *format, ...)
  note = g_strdup_vprintf(...
  gtk_idle_add(doGuiMessage, note);
A call to guiMessage() registeres doGuiMessage() to be called from the
main-loop. As soon as the main-loop is idle, it calls doGuiMessage() which
in turn creates the message window.

Any objections?
