* ghook.[hc]: destruction cleanup. there's one
->finalize_hook member in the hooklist now that gets
called when a hook should be destroyed, that's it.
that function is guarranteed to be called only when
all ref_counts to the hook vanished, thus also when
the hook is not in call.
Thu Mar 8 16:35:48 2001 Tim Janik <timj@gtk.org>
* gparamspecs.[hc]: s/g_param_spec_string_c/g_param_spec_stringc/.
* gsignal.[hc]: fixed accumulator invocation, implemented emission
hooks. and no, neither of these callbacks are called via a closure,
language bindings can wrap the accumulator and emission hook
interface, they already get parameters marshalled into a GValue array.
(g_signal_connect): removed this function as its C specific, doesn't
cover the swapped argument, is too close to its broken original
gtk_signal_connect() and creates demand for _swapped, _after and
_swapped_after variants <brrr>.
(g_signal_connectc): convenience macro to connect a C handler
func with data, like the old g_signal_connect() plus swapped
argument.
* gtype.h:
* gboxed.c: added G_TYPE_VALUE boxed type.
