Wed May 6 02:16:34 1998 Tim Janik <timj@gtk.org>
* gtk/gtksignal.c: reimplemented the signal storage system to use a
linear array rather than a hash table.
be carefull *not* to keep any GtkSignal pointers across invokations
of gtk_signal_next_and_invalidate() and therefore gtk_signal_new[v]().
general code cleanups, made all allocations through memchunks.
(gtk_signal_lookup): we now do the lookup of signals through a key_id
for the signal names to avoid multiple hashing of the signal name on
lookups for the several hirarchy levels of an object.
Tue May 5 15:33:27 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmain.c (gtk_init): added gtk_signal_init() to avoid repeatedly
checking for signal initialization in gtksignal.c.
* gtk/gtktypeutils.c (TYPE_NODES_BLOCK_SIZE): reseted this to 200 after
a long debugging period ;)
Mon May 4 00:30:11 1998 Tim Janik <timj@gtk.org>
* gtk/gtktypeutils.h (GTK_TYPE_IS_A): new macro to speedup
gtk_type_is_a().
* gtk/gtktypeutils.c: reimplemented the type storage system to use a
linear array rather than a hash table. it actually speeded up testgtk
for a *considerable* amount. be carefull *not* to keep any GtkTypeNode
pointers across invokations of gtk_type_node_next_and_invalidate() and
therefore gtk_type_unique()!
* gtk/gtkobject.h (GTK_IS_OBJECT_CLASS): new macro to test for the
inheritance of a class pointer.
(GTK_OBJECT): modifications for speedups.
(GTK_IS_OBJECT): likewise.
(GTK_OBJECT_CLASS): likewise.
(suggested by owen).
* gtk/gtkcontainer.h (GTK_IS_CONTAINER_CLASS): new macro.
* gtk/gtkwidget.h (GTK_IS_WIDGET_CLASS): new macro.
* gtk/gtk.defs (GtkTooltips): define GtkTooltips as object not as boxed,
since its derivation changed 4 month ago ;(. showed up with the unique
type name checking code in gtk_type_unique().
* random guint->GtkType and macro fixups.
