Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org> * gboxed.c: fixed dealing with collection/lcopy of NULL values. * gclosure.h: removed insane ramblings, added G_CALLBACK() a casting convenience macro. * Makefile.am: cleanups, marshaller generation rules. * gmarshal.[hc]: new files with GRuntime standard marshallers. * glib-genmarshal.c: fix log domain, support gruntime standard marshallers, suport G_TYPE_PARAM, come with extern "C" and #include gmarshal.h. * glib-genmarshal.1: reflect glib-genmarshal.c updates. * gobject.[hc]: implement object constructor. rework parameter changed notification queueing, we support queue freezes now and don't dispatch from an idle handler anymore. parameter->property rename hassle. implemented ::properties_changed and ::notify::* signals for property change notification (the later supports property names as details). added signal connection and named data properties. (g_signal_connect_object): new function to setup while_alive connections. (g_object_class_install_property): sink properties now, since they are initially floating. (g_object_steal_data): (g_object_set_data_full): (g_object_set_data): (g_object_get_data): set/get data by using g_datalist_*() functions directly. (g_object_queue_param_changed): nuked. (g_object_freeze_notify): start queueing of property changes (freeze/ thaw calls stack). (g_object_notify): announce changes of a certain property directly. (g_object_thaw_notify): process queue of property changes, therefore emitting GObject::notify::detail with detail being the changed properties names. (G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former G_WARN_INVALID_PARAM_ID(). * gparam.[hc]: param specs are now initially floating and need to be sunken with g_param_spec_sink(), support G_TYPE_PARAM values. added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags, required by GObjectClass.constructor(). * gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER and G_TYPE_CCALLBACK respectively. * gsignal.[hc]: cleanups. (signal_id_lookup): after walking the anchestry, try interfaces as well. (g_signal_new): new function to create signals from varargs type list. (g_signal_connect_closure): closure connection variant that works from signal name+detail. (g_signal_connect_data): c handler connection variant that works from signal name+detail. (g_signal_emit_valist): emit signal for an instance with paraneters collected from a va_list. (g_signal_emit): emit signal, taking parameters from varargs list. (g_signal_emit_by_name): same as g_signal_emit, working from signal name+detail. (signal_emit_R): return whether return_value needs to be altered. * gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all the points that need to reflect the upcoming rename. melt g_type_conforms_to() functionality into g_type_is_a(), as that is what we really want (liskov substitution principle). assorted changes to other files due to conforms_to->is_a. * gvalue.[hc]: implemented g_value_set_instance() that sets a value from an instantiatable type via the value_table's collect_value() function (based on an idea from James Henstridge <james@daa.com.au>). cleanups/fixes. * gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.
