Mon Feb 15 23:55:27 1999 Owen Taylor <otaylor@redhat.com>
* gtk/testgtk.c (create_text): Use a ScrolledWindow
test how Text widgets work within ScrolledWindow.
(POLICY_AUTOMATIC drew very badly, so it uses
POLICY_ALWAYS for the vscrollbar)
* gtk/gtktext.c (gtk_text_unrealize): Free the cache
in the unrealize handler. Some code in gtktext.c
assumes that if text->line_start_cache is non-NULL,
the widget is realized. We'll recompute it again
anyways if we later re-realize.
Wed Feb 10 01:02:46 1999 Lars Hamann <lars@gtk.org>
* gtk/gtkclist.c (real_remove_row):
* gtk/gtkctree.c (gtk_ctree_remove_node): don't autoselect focus_row
in case of GTK_SELECTION_EXTENDED
* gtk/testgtk.c : few changes in clist/ctree examples.
Sun Feb 7 19:49:21 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwindow.c (gtk_window_move_resize): Fixed some
bugs with set_default_size.
Sat Feb 6 13:23:51 1999 Owen Taylor <otaylor@redhat.com>
* docs/Changes-1.2.txt: Added information about
the change to gtk_widget_size_request().
* gtk/gtkentry.c: Call gtk_widget_get_child_requisition
explicitely since we differentiate between the usize
set by the user and what we got. (Ugh)
* gtk/gtkwidget.[ch] (gtk_widget_get_child_requisition):
New function to return the effective size of a widget
as it looks to its parent.
* gtk/gtkwidget.c (gtk_widget_size_request): Leave
widget->requisition set to exactly what the widget
asked for, and then make a copy of that into
the requisition argument. Allow a NULL requisition
argument, and, if G_ENABLE_DEBUG, warn if
requisition == &widget->requisition.
* gtkalignment.c gtkaspectframe.c gtkbutton.c gtkclist.c
gtkcontainer.c gtkentry.c gtkeventbox.c gtkfixed.c
gtkframe.c gtkhandlebox.c gtkhbox.c gtkhpaned.c
gtklayout.c gtklist.c gtklistitem.c gtkmenu.c
gtkmenubar.c gtkmenuitem.c gtknotebook.c
gtkoptionmenu.c gtkpacker.c gtkscrolledwindow.c
gtktable.c gtktoolbar.c gtktree.c gtktreeitem.c
gtkvbox.c gtkviewport.c gtkvpaned.c gtkwindow.c
Avoid calling gtk_widget_size_request with
requisition == widget->requisition; use
gtk_widget_get_child_requisition to get the
size of children.
Wed Jan 20 11:19:00 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtklabel.c: Use floor() instead of truncating
to integer values so we get translation invariance.
* gtk/gtklayout.c (gtk_layout_size_allocate): Set upper
and lower values for adjustments in size_allocate().
* gdk/gdkwindow.c gdk/gdk.h gdk/gdkprivate.h: New
function gdk_window_set_static_gravities() to set
up a window for guffaw scrolling.
* gdk/gdkwindow.c (gdk_window_internal_destroy): Set flags
indicating destroyed state before cleanup.
* gtk/gtkprivate.h gtk/gtkwidget.c: Add a new
private flag IS_OFFSCREEN. If set, this indicates
to GTK+ that the widget is not to be considered
viewable regardless of its map state. Queued draws
on offscreen widgets are suppressed.
Added new function static gtk_widget_is_offscreen() to
check this flag on a widget and its ancestors.
* gtk/gtklayout.[ch]: Major revisions.
- Use gdk_window_set_static_gravities to set static gravity
on all child windows, and thus avoid having to create a window
for NO_WINDOW children.
- Adjust allocations of children as we scroll them
so queued draws work correctly.
- Don't allocate our children directly in a put()
or move(); just queue a resize() like every other
widget.
* gtk/testgtk.c: Make the arrows on the scrollbars
work, create a larger and more demanding test.
Sat Jan 23 11:15:39 1999 Owen Taylor <otaylor@gtk.org>
* gdk/gdkdnd.c (gdk_window_register_dnd): X expects
longs, not uint32 for XChangeProperty, when
format == 32.
* gdk/gdkdnd.c (motif_read_initiator_info): Byte-swap
the MotifInitiatorInfo structure if necessary.
* gdk/gdkdnd.c: When extracting and constructing
Motif DND messages, don't use data.s[], data.l[]
since on 64bit architectures, these won't necessarily
be in the same place with data.b[].
* gtk/testdnd.c (target_drag_drop): Return TRUE for
drag_drop within the drop zone.
* gtk/gtkdnd.c (gtk_drag_dest_handle_event): Only send
a XmTRANSFER_FAILURE if no drop site is found, not
on every drop!
Fri Jan 22 07:33:44 1999 Tim Janik <timj@gtk.org>
* gtk/gtkvscale.c (gtk_vscale_pos_trough): take value_spacing into
account for GTK_POS_LEFT.
* gtk/gtkradiobutton.c (gtk_radio_button_set_group): use
gtk_toggle_button_set_active () to set the new state.
(gtk_radio_button_new): only _set_group if group != NULL.
(gtk_radio_button_clicked): reference the widget.
(gtk_radio_button_init): make radio buttons active upon
startup.
Sun Jan 17 14:52:29 1999 Tim Janik <timj@gtk.org>
* gtk/gtkcompat.h:
* gtk/gtkcheckmenuitem.[hc]:
deprecated gtk_check_menu_item_set_state, people should use
gtk_check_menu_item_set_active instead.
* gtk/testgtk.c:
s/gtk_check_menu_item_set_state/gtk_check_menu_item_set_active/.
Fri Jan 15 19:16:42 1999 Tim Janik <timj@gtk.org>
* gtk/Makefile.am: define GTK_DISABLE_COMPAT_H for compilation of gtk
code.
* gtk/gtkrc.c (gtk_rc_style_unref): added an assertment.
* gtk/gtkcompat.h:
* gtk/gtklabel.h:
don't provide compatibility defines if GTK_DISABLE_COMPAT_H is defined.
* gtk/gtkstyle.h:
* gtk/gtkstyle.c: coding style, indentation and alignment fixups.
(gtk_draw_string):
(gtk_paint_string):
(gtk_draw_polygon):
(gtk_style_set_background): fixed assertments.
(gtk_default_draw_ramp):
(gtk_default_draw_cross):
(gtk_default_draw_oval): issue warnings since these functions aren't
yet implemented.
* gdk/gdkwindow.c:
(gdk_window_hide): only unmap window if already mapped.
(gdk_window_show): only map window if !mapped.
(gdk_window_internal_destroy): destroyed windows can't be mapped.
* gtk/gtkwidget.c (gtk_widget_event): don't ignore expose events just
because a resize is queued on a widget, we rely on the expose events
now.
Fri Jan 15 10:22:21 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.c (gtk_widget_class_init):
nparams for selection_get should be 3, not 2.
[ From Damon Chaplin <damon@karuna.freeserve.co.uk> ]
* gtk/gtkeventbox.c (gtk_event_box_paint): Add a paint
routine so queued redraws work inside event boxes.
Thu Jan 14 17:47:37 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkentry.c (gtk_entry_draw_cursor_on_drawable): Only
redraw character under cursor when not displaying
highlighted selection.
* gdk/gdkrgb.c (gdk_rgb_init): Add in a cast to
gpointer to make IRIX cc happy.
Thu Jan 14 12:29:50 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkcheckbutton.c (gtk_check_button_draw): Restructure
the drawing code to remove a bit of duplication -
and to remove a call to gtk_widget_draw_focus()
that queues a redraw when an expose occurs.
* gtk/gtklabel.c (gtk_label_expose): Fix up handling
of ypadding.
* gtk/gtknotebook.c (gtk_notebook_draw): If we redraw
the whole widget, also redraw the corresponding
areas of the child widget. (have_visible_child
still has some problems)
* gdk/gdkpixmap.c: Change some g_new's to g_new0 so
that fields unused for pixmaps get initialzized
sanely.
* gdk/gdk.h gdk/gdkwindow.c gdk/gdkprivate.h: Add new calls
gdk_window_is_visible() and gdk_window_is_viewable()
and a mapped flag to the window private structure.
* gtk/gtkbin.c gtk/gtkclist.c gtk/gtkfixed.c gtk/gtkitem.c
gtk/gtklayout.c gtk/gtklist.c gtk/gtkmenushell.c
gtk/gtknotebook.c gtk/gtkpaned.c gtk/gtktree.c
gtk/gtktreeitem.c gtk/gtkviewport.c:
Map windows after mapping children.
* gtk/gtkwidget.c (gtk_widget_clip_rect): Handle
rectangles completely clipped away correctly.
* gtk/gtkwidget.c (gtk_widget_idle_draw): Don't
call gtk_widget_draw if width or height is 0.
* gtk/gtkwidget.c (gtk_widget_idle_draw): Don't
rely on GTK_REDRAW_PENDING after we've cleared
it. (This was causing draw-combining to not
happen at all).
* gtk/gtkbin.c gtk/gtkscale.c: Remove uneccessary calls
to gtk_widget_queue_draw() when mapping.
Tue Jan 12 18:30:51 1999 Owen Taylor <otaylor@redhat.com>
* gtk/testdnd.c (label_drag_data_received): Add
a drag_data_received handler for the label.
Tue Jan 12 15:01:50 1999 Owen Taylor <otaylor@redhat.com>
* gdk/gdkevents.c: Removed the putback_events queue,
since it was causing problems with event ordering -
just keep a single queue. If we need it, we can
add priorities to events.
* gdk/gdkevents.c: Annotate events with flags - we allocate
a GdkEventPrivate structure in gdk_event_new() and use these
flags to mark an event being translated as "pending" -
I.e., not yet ready to be dequeued. So we can put
the event on the queue and get the order of the
events right. (This solves the double-click problems)
* gdk/gdk.h gdk/gdkevents.h: Add gdk_event_peek() to get a copy
of the next event on the event queue.
* gtk/gtkmain.c (gtk_main_do_event): Use gdk_event_peek()
to check the next event without causing event queue
reordering.
Tue Jan 12 13:47:07 1999 Tim Janik <timj@gtk.org>
* reworked the redrawing heuristics somewhat, this fixed a bunch of
existing redrawing problems and majorly reduces overall redrawing needs
during normal operation. basically we now only queue redraws when
neccessary and much rely on the draw_area coalescing code in gtkwidget.c
to optimize the queued portions. widgets will now upon reallocation only
get redrawed if their allocation has changed. upon hide/show only the
area allocated by the child will be queued for the parent, this has the
side effect that parents which change their appearance in dependance on
the numer of visible children have to keep track of their children's
visiblity and eventually fully redraw themselves. this is a minor
constrain with great benefits in terms of redraw reduction, and only got
triggered by the notebook widget.
* gtk/gtkwidget.c:
(gtk_widget_queue_clear): don't bother if width and height == 0.
(gtk_widget_queue_clear_child): new static function to queue a redraw of
the area obscured by a child on a parent.
(gtk_widget_queue_resize): queue_clear the widget if it is drawable.
(gtk_widget_show): queue resize on the widget before showing.
(gtk_widget_hide): queue resize on the widget after hiding.
(gtk_widget_map): queue_draw the widget after mapping.
(gtk_widget_unmap): queue_clear_child the widget.
(gtk_widget_size_allocate): queue_clear_child and queue_draw if the
widget's allocation changed.
(gtk_widget_unparent): queue_clear_child so the parent redraws obscured
portions.
(gtk_widget_real_show):
(gtk_widget_real_hide):
(gtk_widget_real_map):
(gtk_widget_real_unmap):
(gtk_widget_real_size_allocate): don't bother with redraw queueing,
descendants that override these functions don't do either and we handle
all redrawing/resizing related stuff before or after the signal emission
now.
* gtk/gtkcontainer.c:
(gtk_container_resize_children): don't bother about redrawing anymore
since gtk_widget_size_allocate handles that for us now.
* gtk/gtknotebook.h:
* gtk/gtknotebook.c:
added a flag have_visible_child to indicate whether we need to draw
non child related portions at all, e.g. shadows etc.
(gtk_notebook_draw): if have_visible_child changed, do a full paint
instead of updating a small area only.
Mon Jan 11 20:44:35 1999 Tim Janik <timj@gtk.org>
* gtk/gtkstyle.c: changed gtk_style_apply_default_pixmap to
gtk_style_apply_default_background which takes an extra argument
copy_area to determine NO_WINDOW widget pixmap copying.
changed callers accordingly.
* gtk/gtktogglebutton.c:
(gtk_toggle_size_allocate):
(gtk_toggle_button_expose):
(gtk_toggle_button_paint): avoid messing with our parent's window if
toggle_button->draw_indicator == TRUE and we are a NO_WINDOW widget.
* gtk/gtkcheckbutton.c (gtk_real_check_button_draw_indicator): draw
the draw_indicator with GTK_STATE_ACTIVE if the toggle button is active.
* gtk/check-n.xpm:
* gtk/check-y.xpm:
* gtk/testgtkrc: set pixmaps for ACTIVE and NORMAL check button
bg_pixmaps.
Mon Jan 11 15:23:32 1999 Tim Janik <timj@gtk.org>
* gtk/gtktogglebutton.c: eliminated some queue_draws when invoking
gtk_widget_set_state, since that cares about redrawing already.
some code cleanups.
* gtk/gtktogglebutton.[hc]:
* gtk/gtkfontsel.c:
* gtkgamma.c:
s/gtk_toggle_button_set_state/gtk_toggle_button_set_active/ since
set_state is already taken by gtkwidget.h.
* gtk/gtkcompat.h: #define gtk_toggle_button_set_state
gtk_toggle_button_set_active.
* gtk/gtkstyle.c: some indentation cleanups.
Mon Jan 11 13:18:37 1999 Tim Janik <timj@gtk.org>
* gtk/gtkwindow.c:
(gtk_window_key_release_event):
(gtk_window_key_press_event): only pass key events to the focus widget
if it is sensitive.
* gtk/gtkmenuitem.c (gtk_menu_item_select_timeout): don't popup the
submenu if it isn't sensitive.
(gtk_menu_item_paint): state_type doesn't need to be reset to
GTK_STATE_INSENSITIVE if the widget is insensitive anyways.
* gtk/gtkcontainer.c (gtk_container_real_focus):
* gtk/gtklist.c (gtk_list_focus):
* gtk/gtkmenushell.c (gtk_menu_shell_move_selected):
* gtk/gtknotebook.c (gtk_notebook_focus):
s/GTK_WIDGET_SENSITIVE/GTK_WIDGET_IS_SENSITIVE/ since a widgets
sensitivity is determined through the parent as well,
GTK_WIDGET_SENSITIVE is only of interest inside gtkwidget.c, everywhere
else GTK_WIDGET_IS_SENSITIVE (widget) needs to be used to check for
sensitivity.
* gtk/gtkaccelgroup.c (gtk_accel_group_activate): don't activate
object if it is an insensitive widget.
Thu Dec 17 10:53:20 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtklabel.c (gtk_label_set_text): Free
previous label->label_wc.

* gtk/gtkentry.c (gtk_entry_draw_cursor_on_drawable):
Redraw the character under the cursor when removing
the cursor.
Wed Dec 16 13:06:17 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdk.[ch] gtk/gtkmain.[ch] gtk/gtkprivate.h: Move main
thread lock back to GDK - we need it there for locking
when translating events. Rename things appropriately.
Wed Dec 16 11:44:21 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_expose): Fix a x/y typo.

* gtk/gtkctree.c gtk/gtkclist.c gtk/testgtk.c: Use
base[NORMAL] instead of bg[PRELIGHT] so CLists now can be
used in detergent commercials.
Tue Dec 15 14:30:35 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdk.h gdk/gdkfonts.c: Added gdk_text_extents_wc()
* Patch from Jonathan Blanford <jrb@redhat.com> to add line wrapping
to label. (Based on patch from Jeff Dairiki
<dairiki@mac-ceope.apl.washington.edu> gtk-dairiki-971208-0)
- Adds new function gtk_label_set_line_wrap()
- implement GTK_JUSTIFY_FILL.
- rename gtk_label_set to gtk_label_set_text() add
gtk_label_set() to gtkcompat.h.

that we handle underlining and line breaks correctly
for multi-byte strings.
Tue Dec 15 11:37:05 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmain.c: Fixed up some warnings.
Tue Dec 15 10:32:01 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtk{h,v,}paned.{c,h}: Add new functions
gtk_paned_set_position(),
gtk_paned_pack1/2(). The latter take a
shrink and resize parameters, that allows setting
minimum sizes and getting 'relative' resizing.
Tue Dec 15 01:38:53 1998 Owen Taylor <otaylor@redhat.com>
* gtk/Makefile.am: Commented out testthreads from
the build process, since we won't have any idea
how to create a thread.
* configure.in (LIBS): use glib-config ... gthread
so we always build a thread-compatible library.
* gtk/gtkaccellabel.c gtk/gtkclist.c gtk/gtkcolorsel.c

gtk/gtkrange.c gtk/gtkselection.c gtk/gtkspinbutton.c
gtk/gtktext.c gtk/gtktooltips.c gtk/gtkwidget.c:
Add GTK_THREADS_ENTER/LEAVE pairs around timeouts
and idles to account for the fact that they are no
longer called within the GTK+ lock.
* gtk/gtkprivate.h: Added definitions for locking
the main GTK+ mutex.
* gtk/gtkmain.c: Re-implement the main loop
in terms of the GLib main loop.
* gdk/gdk.h gdk/gdkthreads.c gdk/Makefile.am: Removed threading
functionality, as it seems better to subsume GDK within the
GTK+ lock than vice-versa.
* gdk/gdkevents.c: New file, containing event handling bits
from gdk.c.
* gdk/gdkevents.c: Implement event source for GDK
events.

-Yosh
Mon Dec 7 10:27:09 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.c: Destroy widgets _after_ propagating unrealize
signals through the widget heirarchy. This is unpleasant, as it
causes more X traffic, but is necessary, because we have to clean
up our Input Contexts before destroying the X windows.
(from matsu-981109-0.patch)
Mon Dec 7 10:18:18 1998 Owen Taylor <otaylor@redhat.com>
Applied gtk-a-higuti-981202-0 :
[ a-higuti@math.sci.hokudai.ac.jp (Akira Higuchi) ]
* gdk/gdk.h gdk/gdk.c
(gdk_mbstowcs): New function. Nearly equals to mbstowcs, but
implemented by a combination of Xlib functions, so
it works even with X_LOCALE.
(gdk_wcstombs): New function.
(g_mbtowc): Removed. No longer needed.
* gdk/gdk.h gdk/gdkfont.c gdk/gdkdraw.c:
Added _wc() variants to gdk_text_width(),
gdk_char_width(), gdk_draw_text(),
* gdk/gdki18n.h
(mblen, mbtowc, wctomb, mbstowcs, wcstombs,
wcslen, wcscpy, wcsncpy):
Removed. No longer needed.
(iswalnum): Removed.
(gdk_iswalnum): New macro.
(gdk_iswspace): New macro.
* gdk/gdktype.h
(GdkWChar): New typedef.
* gtk/gtkentry.h, gtk/gtkentry.c
There are many changes according to the change of the
internal representation of text, from multibyte string
to wide characters.
* gtk/gtkprivate.h, gtk/gtkmain.c
Removed the variable gtk_use_mb and related codes.
* gtk/gtkspinbutton.c
Some changes according to the change of type of entry->text.
* gtk/gtktext.h, gtk/gtktext.c
Changed the internal representation of text. We use GdkWchar
if a fontset is supplied. If not, we use guchar to save
memory.
* gtk/testgtk.c: Functions to test the toolbar space style.
* gtk/gtktoolbar.c: Add a private GtkToolbarChildSpace subclass of
GtkToolbarChild to hold allocation. Set default space style to
GTK_TOOLBAR_SPACE_EMPTY, define SPACE_LINE_* for separator
fraction defaults.
(gtk_toolbar_paint_space_line): New function; paints the separator
line, using "toolbar" as the detail.
(gtk_toolbar_expose): (gtk_toolbar_draw): Handle CHILD_SPACE when
style is set to SPACE_LINE.
(gtk_toolbar_size_allocate): Store space allocations.
(gtk_toolbar_insert_element): If we are a space, allocate and
initialize a GtkToolbarChildSpace instead of a GtkToolbarChild.
(gtk_toolbar_set_space_style): New function.
* gtk/gtktoolbar.h: Add GtkToolbarSpaceStyle, with styles of EMPTY
and LINE. Add prototype for gtk_toolbar_set_space_style.
Mon Dec 7 01:29:27 1998 Owen Taylor <otaylor@gtk.org>
* gtk/gtkwindow.c: New functions
gtk_window_set_transient_for() - set up a "transient for" relationship.
gtk_window_set_default_size() - set the initial size of a window
distinct from its minimum size.
gtk_window_set_geometry_hints() - Allow the user to set
minimum, maximum sizes, aspect rations, and gridded geometry,
possibly all with respect to a subwidget of the window.
These interfaces are still a wee bit experimental.
* gdk/gdk.c: Added gdk_window_set_transient_for(),
gdk_window_set_geometry_hints(), and gdk_window_set_role().
* gdk/gdktypes.h: Added new types for find-grained specification
of WM hints.
* gtk/testgtk.c: Various changes to tests to test the
above new functions.
* gtk/gtkfontsel.c: Squash a few 'const' warnings.
* gtk/gtktogglebutton.c (gtk_toggle_button_realize): Restored
call to gtk_style_set_background() to prevent egregious
flashing to black.
Mon Dec 7 03:08:39 1998 Tim Janik <timj@gtk.org>
* gtk/gtktypeutils.h:
* gtk/gtktypeutils.c: reverted marius change to expose the type systems
internal type info data to the user. if such functionality is required
we should provide wrapped accessors, ala gtk_signal_query().
* gtk/gtksignal.c (gtk_signal_connect_by_type): reverted marius change,
since it destroys the possibility to implement automatic marshaller
lookups some day, and it also disables third party code's ability to
connect to any signal. also the GtkTypeInfo structures are dynamically
allocated memory portions, so only the type system is really allowed
to access that stuff.
Mon Dec 7 01:32:18 1998 Tim Janik <timj@gtk.org>
* gtk/gtkfilesel.c (gtk_file_selection_key_press): always intercept the
Tab key on the entry. the focus shouldn't get lost even if completion
is attempted from an empty entry, since an empty entry string does
indeed have a valid completion meaning (complete all).
(gtk_file_selection_init): cast the gchar array parameter in calls to
gtk_clist_new_with_titles() to quit compiler warnings.
(check_dir): the no_stat_dirs struct must not be const, since we do
indeed modify its contents.
* gtk/testgtk.c (event_watcher): adapted prototype to fit new emission
hook semantics.
* gtk/gtksignal.h:
* gtk/gtksignal.c:
changed emission allocation, so we don't use a doubly linked list
but link ourselfs (singly linked).
changed emission hooks, they get the emision parameters passed as
well now and are emitted during the actuall signal emission (after
the RUN_FIRST class method, but prior to RUN_FIRST handlers).
the existing restrictions do still apply to signal emission hooks,
i.e. an emission may not be stopped or restarted from an emission hook.
due to possibly huge perfomance impacts, frequent use of emision hooks
is also not recommended.
(gtk_signal_next_and_invalidate): added an
assertments which explicits what the code assumes anyways: a
maximum amount of 65535 signals.
* gtk/gtkcontainer.h: deprecated gtk_container_foreach_interp(),
gtk_container_foreach_full() should be used instead.
* gtk/gtkmain.h:
deprecated gtk_timeout_add_interp and gtk_idle_add_interp, since
we provide _full variants.
* gtk/gtksignal.h: deprecated gtk_signal_connect_interp(), we provide
gtk_signal_connect_full() for long enough now.
Mon Nov 30 10:11:29 1998 Tim Janik <timj@gtk.org>
* gtk/testgtkrc: merged testgtkrc with the pre-themes one, removed
system specific includes.
* gtk/gtksignal.c: asured that stop and restart emissions are also
checked and processed for not connected objects. fixed up restart
emission administration. invoke emission hooks after emission, hooks
are not supposed to muck around with the current emission, and
may also not cause emission restarts. fixed up stop emission
administration.
Mon Nov 30 06:20:36 1998 Tim Janik <timj@gtk.org>
* gtk/testgtk.c: added an event watcher for enter/leave based on
signal emission hooks.
* gtk/gtkobject.c (gtk_object_class_init): made GtkObject::destroy a
GTK_RUN_NO_HOOKS signal.
* gtk/gtksignal.h:
* gtk/gtksignal.c: implemented emission hooks, new hooks can be added
to a signal with gtk_signal_add_emission_hook or
gtk_signal_add_emission_hook_full, and can be removed again with
gtk_signal_remove_emission_hook.
* gtk/gtkenums.h: remove GTK_RUN_MASK, since it doesn't represent
an appropriate mask for signal runtypes for a long time now.
added GTK_RUN_NO_HOOKS value, which is used to flag signals
that do not allow the running of signal hooks.
Sat Nov 28 03:13:42 1998 Tim Janik <timj@gtk.org>
