------------------------------> snippets end <------------------------------
And i have wrote
DBusGProxy as GProxy, dbus_g_proxy_get_type if dbus
in `gtk2hs/tools/hierarchyGen/hierarchy.list` file.
Then gtk2hs will generate Types.chs file for type `DBusGProxy`, and below is
`dbus/System/DBus/Types.chs` file.
Types.chs
Description: Binary data
So code "{#import System.DBus.Types#}" in GProxy.chs.pp should works fine,
because
Types.chs file generate correctly, right?
Because objects in DBus-Glib just derived from GObject, so i just copy
and replace `gconf` in Makefile.am for binding DBus-Glib.
And i have check Cairo example, haven't saw any difference.
I don't understand "these rules have changed recently with the
multi-threading fixes.", can you explain it more detail?
Thanks!
