Wrapping GHashTable, which approach?

[Robin Lee <robinlee sysu gmail com>]

Hi,

I am learning to wrap a GObject-based library with gmmproc and encounter a
signal callback that comes with an argument of type GHashTable. But there is
no wrapper for this type, so I am figuring out what to do next.

One straight approach is wrapping GHashTable like Glib::BalancedTree for GTree.

But I also found that glibmm is following a trend that use std::vector in API
instead of exposing wrappers of Glib data structures. So for GHashTable, we
may replace the argument with type std::unordered_map, and make a
HashTableHandler for the conversion.

Any ideas?
