Tue Oct 24 22:09:14 2000 Tim Janik <timj@gtk.org>
* glib-object.h: added newly added gobject/ headers.
* gmesage.c: print g_message() output to stderr instead of stdout.
Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org>
* gtype.c (g_type_free_instance): for the moment, freeing object
structures will fill their memory portion with 0xAA. there's a
FIXME there, remove this line at a later point.
Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org>
* glib-genmarshal.1:
* glib-genmarshal.c: added publically installed marshaller generator.
* gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
interface VTable from instances.
Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org>
* gobject.[hc]: new functions for closure maintenance:
(g_object_watch_closure): maintain validity of the object and
the closure for objects that are used as data part of a closure.
(g_cclosure_new_object): convenience function to create C closures
that have an object as data argument.
(g_closure_new_object): convenience function to create closures
that have an object as data argument.
* gclosure.[hc]: implementation of GClosure mechanism.
a closure is basically an encapsulation of a callback function
and its environment. ideally, most places supporting callback
functions will simply take a GClosure* pointer and thus unify
callback environments wrg destroy notification etc.
GClosure provides destroy notifiers for arbitrary data pointers,
reference counting, invalidation notification (it can be invalidated
which is merely a deactivate state) and a marshallinbg abstraction.
GCClosure is also provided in these files, they present a specialized
GClosure implementation for C language callbacks.
* genum.c: macro cleanups.
* gboxed.[hc]: new files, for boxed type abstraction.
(g_boxed_copy): copy a boxed structure
(g_boxed_free): free a boxed structure
(g_value_set_boxed):
(g_value_get_boxed): standard GValue functions for boxed types
(g_boxed_type_register_static): convenience function for easy
introduction of new G_TYPE_BOXED derivatives.
* gparam.[hc]: introduced g_param_type_register_static(), a short hand
for creation of new GParamSpec derived types.
* gtype.[hc]: many fixes, introduced ability to flag individual
type nodes as ABSTRACT upon registration, added value_peek_pointer()
to the value table to peek at GValue contents as a pointer for types
that support this. fixed up GValue checks.
* gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
to peek at the value contents as pointer.
* *.[hc]: adaptions to type macro fixes and changes in the type
registration API.
* many const corrections over the place.
Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org>
* gtype.c (g_type_conforms_to): this function basically behaves like
and is_a check, except that it _additionally_ features interfaces
for instantiatable types. enforce this in the second branch as well
(`type' conforms_to `type') even if `type' is not an interface type.
Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org>
* gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.
* gtype.[hc]:
* gobject.c:
* gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
and G_TYPE_POINTER.
Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org>
* gbsearcharray.[hc]: long standing needed generic implementation
of a binary searchable, sorted and dynamically sized array.
