* gtk/gtksignal.[ch] gtk/gtkmain.[ch] gtk/gtkcontainer.[ch]
gtk/gtkselection.[ch] gdk/gdk.[ch] gtktypeutils.h
Replaced all _interp functions with _full functions.
(_interp functions left in for compatibility until 0.99.5).
Difference: _full functions take _both_ a C-language callback and a
marshaller, and simply ignore the C-language callback
if the marshaller is present. This allows the destroy notification
to be used without marshalling.
gtk_selection_add_handler[_full]() regularized to agree
with other callbacks.
Also, added gtk_input_add_full() to the header file.
(gtk_input_add_interp() was never there)
* gtk/gtkmain.[ch] gtk/gtkwidget.c: Idle functions are now prioritized.
Added new function gtk_idle_add_priority to create
an idle with a specified priority (default is zero)
constants #defined - GTK_PRIORITY_[HIGH/INTERNAL/DEFAULT/LOW]
(redraws, resizes run at GTK_PRIORITY_INTERNAL)
* gtk/gtkentry.c gtk/testselection.c: changes to keep up with change
to gtkselection.c.

* gtk/gtksignal.h:
* gtk/gtksignal.c:
ok, there have been several severe bugs in the signal handler
referencing and ->next connection stuff. these bugs caused
invokations of handlers that are disconnected and - worse -
destroyed already. invokation of *destroyd* handlers mean:
anything can be executed , because the handler structure can just
as well be realocated.
at the cost of an extra ->prev field per handler we should have a
reasonable stable system now, because of the various places that
can cause a handler to be disconnected (*any* handler invokation can
cause *any* or *all* handlers to be disconnected, there is no way
around a doubly linked list, actually handler disconnection has never
worked correctly because of this.
handlers are connected together via a *doubly* linked list now, and it
is *not* valid to remove a handler out of this list untill all its
references have been droped, i.e. handler->ref_count==0.
to prevent emissions of disconnected but still referenced handlers,
disconnected handlers are simply marked as blocked and get an id of 0
which is an invalid signal handler id.
the handler->id has been changed to have 28 significant bits (using
alignment gaps), since 65536 (old range: guint16) signal connections
(as a total) can easily be reached by complex applications.
this whole handler thingy is at least as tedious as writing doubly
linked list implementations ;)

* gtk/gtklist.h:
* gtk/gtklist.c (gtk_list_remove_items_no_unref): new function
to perform the same actions as gtk_list_remove_items, but
supply the removed widgets with an additional reference count.
* gtk/gtkmain.c (gtk_main_iteration_do): ignore events
with event_widget == NULL, since they are bogus events
from destroyed GdkWindows, exept for the case where
event->type==GDK_PROPERTY_NOTIFY. Always handle expired
timeout functions when returning from this function.
* gtk/gtkwidget.c (gtk_widget_event): ignore GDK_EXPOSE events
if event->window == NULL. Also, if this function couldn't handle
the event for any reason (including failing assumptions), make
the return value to look as if the event had been handled to
avoid further processing (and warnings).
* gtk/gtkwidget.h:
* gtk/gtkwidget.c: remove gtk_widget_sink, because there is
no point in providing such a function.
* gdk/gdk.c (gdk_init): changed options `-name' and `-class'
to `--name' and `--class', because the old names would
confuse getopt(). these arguments have been introduced in the
changes from gtk+970916 to gtk+970925 without a ChangeLog entry,
changing argument names is painful, it would be nice if people
would care about compatibility and consistency in the first place!
Tue Feb 3 15:09:55 1998 Tim Janik <timj@gimp.org>
* gtk/gtkoptionmenu.h:
* gtk/gtkoptionmenu.c: attach/detach to menu widget via
* gtk/gtkmenu.h:
* gtk/gtkmenu.c: new functions gtk_menu_attach_to_widget
and gtk_menu_detach that correspond to the action of
gtk_widget_set_parent and gtk_widget_unparent.
* gtk/widget.c: few fixups.
Mon Feb 2 04:15:08 1998 Tim Janik <timj@gimp.org>
* gtk/gtkmain.c (gtk_propagate_event): fixed a bad, bad referencing
bug that could caused unreferencing of finalized objects.
* gtk/testgtk.c: destroy fileselection on "OK" (this triggered the
above mentioned bug).
* gtk/gtkwidget.h:
* gtk/gtkwidget.c:
* gtk/gtkobject.h:
* gtk/gtkobject.c:
implemented and object reference tracer (gtk_trace_referencing) which
is activated if GTK_TRACE_OBJECTS is defined (currently per default).
in gdb: set the static variable `gtk_trace_object' to point to the
object that you want to have reference traced.
* gtk/gtkfileselection.c: few cleanups.
Mon Feb 2 04:15:08 1998 Tim Janik <timj@gimp.org>
* gtk/gtkcontainer.h:
* gtk/gtkcontainer.c: GTK_RESIZE_NEEDED is a private flag now.
(gtk_container_register_toplevel): new function.
(gtk_container_unregister_toplevel): new function.
* gtk/gtkmain.c: GTK_LEAVE_PENDING is a private flag now.
* gtk/gtkmenu.c: call gtk_container_register_toplevel in
gtk_menu_class_init instead of this dirty gtk_widget_set_parent(,NULL)
hack. new default handler gtk_menu_destroy for calling
gtk_container_unregister_toplevel. removed GTK_ANCHORED, GTK_UNMAPPED.
* gtk/gtkobject.h: macro cleanups, added GTK_DESTROYED flag.
* gtk/gtkobject.c: only emit DESTROY signal if !GTK_OBJECT_DESTROYED
(object).
* gtk/gtkprivate.h: new file that will not be automatically included.
it holds the private flags for GtkWidget along with it's SET/UNSET
and examination macros.
* gtk/gtkwidget.c: private flags: GTK_RESIZE_NEEDED, GTK_REDRAW_PENDING,
GTK_RESIZE_PENDING, GTK_IN_REPARENT, GTK_USER_STYLE. GTK_ANCHORED is
replaced by GTK_TOPLEVEL. added missing UNSET for GTK_IN_REPARENT.
removed the gtk_widget_set_parent(, NULL) hack for toplevels.
upon destroy free memory for widgets with GTK_WIDGET_HAS_SHAPE_MASK.
* gtk/gtkwidget.h: split up the widget flags into a public and a private
portion. added an extra field private_flags to GtkWidget without making
it bigger by using an alignment gap of 16 bit. macro cleanups.
* gtk/gtkwindow.c: removed GTK_ANCHORED. new function gtk_window_destroy
for calling gtk_container_unregister_toplevel. removed the
gtk_widget_set_parent(,NULL), call gtk_container_register_toplevel
instead. remove GTK_UNMAPPED. GTK_RESIZE_NEEDED is private now.
* gtk/gtksignal.c (gtk_signal_disconnect): removed a bug on
removal that cut off the handler list -> living_objects == 0
with testgtk. made some warnings more descriptive.
new function gtk_signal_connect_object_while_alive, which
will automatically destroy the connection once one of the objects
is destroyed. didn't include this before removal of the above
mentioned bug.
* reflected refcounting revolution in ChangeLog
Sun Jan 25 19:15:32 1998 Tim Janik <timj@gimp.org>
* gtk/gtkwidget.h (enum): added new widget flag GTK_LEAVE_PENDING.
* gtk/gtkmain.c (gtk_main_iteration_do): if a widget has
GTK_LEAVE_PENDING set, send it its LEAVE_NOTIFY event, regardless
of a grab or sensitivity.
changed the compression code for enter/leave notify events to
free *both* compressed event, and removed an unneccessary call
to g_list_remove.
* ChangeLog: finally catched up with the recent changes on my part.
Mon Jan 19 09:16:38 1998 Tim Janik <timj@psynet.net>
* gtk/gtkmain.c (gtk_grab_add) (gtk_grab_remove): this is a stack
of grabbing widgets now, having unique entries. the GTK_HAS_GRAB
flag of a widget is set while it is on the stack (wasn't
implemented before).
* gdk/gdk.c (gdk_events_pending): Take putback events into
account
* gdk/gdk.c (gdk_event_free): Handle dropdataavaible memory
allocation correctly. (Incompatible change: client must
_not_ fre event->data and event->data_type.)
* gdk/gdk.c (gdk_event_translate): Changed DND dragging
so that we don't ungrab pointer when we reenter window
to prevent extra Enter/Leave effects which had bad
effects.
Changed drag zone handling to not send uncessary
DragEnter events.
Fixed EnterNotify/LeaveNotify handling. (Only pay
attention to events on window, don't specify these
events to XGrabPointer - that isn't valid, and handle
reverse the sense of the handling of LeaveNotify.)
* gdk/gdkwindow.c (gdk_window_remove_filter): Free removed
filter.
* gtk/gtk.defs (GdkFont): gdk_font_free => gdk_font_unref
* gtk/gtkmain.{c,h} (gtk_events_pending): new function - apps
should use this instead of gdk_events_pending.
* gtk/gtkvbbox.h: Fixed a duplication in the headers.
* gtk/testgtk.c (dnd_drop): Don't free the drop data,
it belongs to the event.
* glib_pre1.h:
* glib_pre2.h:
* glib.h: this file now gets concatenated by makeglib_h from
glib_pre1.h and glib_pre2.h to merge in glibconfig.h wich got
created by configure (done by Jay Painter).
* glib_pre2.h: the g_assert*() and g_return_*_fail() macros
are wrapped by G_STMT_START and G_STMT_END now, to avoid conflicts
when used within if (...) g_macro(); else ... conditionals.
Gtk+:
* fixed some compiler errors, because g_return_if_fail() wasn't used
with a trailing semicolon in some places. fixed few other warnings also.
