# Deprecated GTK+ (and GDK) functions/macros with (E)rror or (W)arning flag:
# (The list is based upon the GTK+ 2.24.8 documentation;
# E: There should be no current Wireshark use so Error if seen;
# W: Not all Wireshark use yet fixed so Warn if seen; (Change to E as fixed)

# Note: Wireshark currently (Jan 2012) requires GTK 2.12 or newer.
#       The Wireshark build currently (Jan 2012) defines GTK_DISABLE_DEPRECATED.
#       However: Wireshark source still has a few uses of deprecated GTK functions
#                (which either are ifdef'd out or GTK_DISABLE_DEPRECATED is undef'd).
#                Thus: there a few GTK functions still marked as 'W' below.
#       Deprecated GDK functions are included in the list of deprecated GTK functions.
#       The Wireshark build currently (Jan 2012) does not define GDK_DISABLE_DEPRECATED
#         since there are still some uses of deprecated GDK functions.
#         They are marked with 'W' below.
