Thu Oct 8 15:53:59 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtktypeutils.c (gtk_type_class_init): Fixed warning
message to print out parent class name correctly.
* gtkfilesel.c: Maintain a list of directories like
/afs we know contain only directories, and avoid
stat'ing files in those directories. (Because
stat'ing all files in /afs is extremely expensive)
To support automounters, try to open directories,
even if we couldn't find them when reading their
parent directory.
Mon Aug 24 18:37:15 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtktext.c: Reference count the fonts used in
the text widget.
* gdk/gdk.h gdk/gdkcolor.c: Rename the color allocation
freeing functions to be more consistent, and more
convenient; leave the old names in for backwards compatibility.
* gdk/gdkcolor.c gdk/gdkprivate.h: Reference count the
allocations in pseudo-color colormaps to greatly reduce
calls to XAllocColor. Keep a per-colormap hashtable to
speed up finding if there is an already-allocated matching
color.
* gdk/gdkcolor.c: Don't just match read the system colormap
when the colormap is created, but synchronize our copy
with the system colormap periodically.
* gdk/gdk.c gdk/gdktypes.h gtk/gtkentry.c gtk/gtktext.c:
Change XIM constants names to match GDK conventions
* gtk/testinput.c: Allow the drawing area to get the focus.
* gtk/testgtk.c: Change around the Text test to demonstrates
multiple fonts, use more colors.
* gtk/gtkwidget.c: Improve gtk_widget_get_colormap()/visual()
so they work after a widget is unrealized.
* gtk/gtktext.[ch]: Remove the requirement that the text
widget be realized before adding text (!) Allocate colors
ourself, instead of requiring the caller allocate them.
Allow changing styles to work properly by keeping track
of the values for a certain property are default or
set explicitely.
* gtk/gtkmenu.h: Added some comments.
* gtk/gtkentry.c: Changes to match XIM constants.
* gtk/gdk.h gdk/gdkwindow.c: Add gdk_drawable_set_data(),
for adding keyed data to drawables. (Uses g_dataset
internally)
* gdk/gdkpixmap.c: Keep track of the colors we allocate,
when creating an XPM - store them as user data for the GdkPixmap,
so we don't leak colors when we create pixmaps from XPM's.
Allocate memory for color information in large blocks instead of
as many little pieces.
Mon Aug 17 01:40:00 1998 Tim Janik <timj@gtk.org>
* configure.in: version bump to 1.1.1, binary age 0, interface age 0.
pass "gmodule" to AM_PATH_GLIB, with that we require libgmodule.so now.
* gtk/gtkmain.c (gtk_init): since glib's g_return*_if_fail macros log
with G_LOG_LEVEL_CRITICAL now, i added "--g-fatal-checks",
"--gdk-fatal-checks" and "--gtk-fatal-checks". that makes up six
different *-fatal-* arguments now. this needs to be revised and
compressed to a reasonable amount of arguments.
Fri Jul 10 00:02:04 1998 Tim Janik <timj@gtk.org>
* gtk/gtkcontainer.h:
* gtk/gtkcontainer.c: deleted most of the argument handling code, since
that is now implemented in gtkarg.c. similar to gtk_object_args_collect,
we now export a new function gtk_container_child_args_collect().
for consistency with the object arguments, a few functions got renamed:
gtk_container_child_arg_get -> gtk_container_child_get,
gtk_container_child_arg_set -> gtk_container_child_set,
gtk_container_child_arg_getv -> gtk_container_child_getv,
gtk_container_child_arg_setv -> gtk_container_child_setv,
gtk_container_add_with_argv -> gtk_container_addv.
note, gtk_container_add_with_args() remained, because its equivalent
would be gtk_container_add(,, ...) which would break all existing code.
(gtk_container_add_child_arg_type): similar to gtk_object_add_arg_type,
we expect the `arg_name' argument to be a const static string now.
(gtk_container_get_child_arg_type): function removed.
Thu Jul 9 07:03:04 1998 Tim Janik <timj@gtk.org>
* gtk/gtkargcollector.c: new file which holds gtk_arg_collect_value().
this is a static inline function that collects command line arguments
from a va_list. this file can just be included in all places that
need this functionality.
* gtk/gtkarg.h:
* gtk/gtkarg.c: new files which implement most of the argument
handling stuff from gtkobject.c. also collected a few more
gtk_arg_* utility functions from else places.
* gtk/gtkobject.h:
* gtk/gtkobject.c: moved most of the argument handling code into
gtkarg.c. we now export gtk_object_args_collect() as a non-public
method with a blind va_list pointer.
(gtk_object_add_arg_type): the `arg_name' argument is required to be a
const static string now.
(gtk_object_get_arg_type): function got removed.
* gtk/gtkwidget.c:
(gtk_widget_set):
(gtk_widget_new): adaptions for gtk_object_args_collect().
* gtk/gtktypeutils.c (gtk_type_init_builtin_types): changed the internal
fundamental type name so as to have a valid prefix, e.g. "bool"->
"gboolean", "string"->"GtkString" and somesuch, left "void" as is,
though that should probably be something like GtkNone since the
type itself is called GTK_TYPE_NONE.
even the internal type names need to avoid name clashes and must live
in their own namespace, several code portions rely on that.
we should relly have typedefs such as typedef gchar* GtkString; so the
fundamental type names can be used for code dumpers just like with all
the Gtk/Gdk types.
Mon Jul 6 18:30:48 1998 Tim Janik <timj@gtk.org>
* gtk/gtkbutton.h:
* gtk/gtkbutton.c: GtkButtons are now derived from GtkBin. we mirror
GTK_BIN (button)->child to button->child to keep source compatibility.
* gtk/gtkoptionmenu.c:
* gtk/gtkclist.c:
* gtkcheckbutton.c: don't refer to button->child, but
GTK_BIN (button)->child instead.
Sat Jun 6 06:01:24 1998 Tim Janik <timj@gtk.org>
* gtk/gtksignal.c (gtk_signal_emitv): fixed an assertment.
* gtk/makeenums.awk: a script to generate the GtkEnumValue arrays from,
this should eventually be done by gentypeinfo.el somewhen.
* gtk/gtkenumvalues.c: new generated file to hold GtkEnumValue arrays.
* gtk/gtktypeutils.h: new function gtk_enum_values() to retrive all the
enum values of an enum type.

* gtk/gtkcurve.h:
* gtk/gtkobject.h:
* gtk/gtkprivate.h:
* gtk/gtkwidget.h:
* gtk/gtkenums.h:
brought enum/flags definitions in sync, added a few more enum
definitions for bindings and pattern matching.
* some more macro and GtkType fixups in various places.
* gdk/gdktypes.h (enum): added a new value GDK_AFTER_MASK, which is used
as a key-release modifier for the binding system.
Fri Jun 5 06:06:06 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmenu.h (struct _GtkMenu): removed GList*children, since it
was a stale list pointer that is already present in GtkMenuShell.
* gtk/gtkmenushell.h (struct _GtkMenuShellClass): added a signal
GtkMenuShell::selection_done which is emitted after the menu shell
poped down again and all possible menu items have been activated.
Thu Jun 4 02:20:42 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmenushell.c (gtk_menu_shell_button_release): flush the x-queue
before activation of the menuitem, so the menu is actually taken off the
screen prior to any menu item activation.
* gtk/gtkctree.c (gtk_ctree_get_row_data): allow function invokation
for NULL nodes.
* gtk/gtkwidget.h:
* gtk/gtkwidget.c: new function gtk_widget_stop_accelerator to stop
the emission of the "add-accelerator" signal on a widget. this is
usefull to prevent accelerator installation on certain widgets.
* gtk/gtknotebook.c (gtk_notebook_menu_item_create): keep the menu
labels left justified, by setting their alignment. stop accelerator
installation for the menu items, since we use dynamic menus.
Wed Jun 3 06:41:22 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmenufactory.c: adaptions to use the new accel groups. people
should *really* use GtkItemFactory. this is only for preserving source
compatibility where possible, use of GtkMenuFactory is deprecated as of
now.
* gtk/gtkobject.h (gtk_object_class_add_user_signal): new function
to create user signals of type GTK_RUN_NO_RECURSE. don't know why i
missed this possibility when i added gtk_object_class_add_user_signal
in late january.
* gtk/gtkmain.c (gtk_init): ignore subsequent function calls.
Sun May 31 07:31:09 1998 Tim Janik <timj@gtk.org>

(gdk_keyval_name): new functions for keyval<->key-name associations.
(gdk_keyval_to_upper):
(gdk_keyval_to_lower):
(gdk_keyval_is_upper):

regards to their cases.
Wed May 27 00:48:10 1998 Tim Janik <timj@gtk.org>

widget's class path.
(gtk_widget_path): new function to calculate a widget's name path.

pattern matching, features reversed pattern matches.
Mon May 11 01:44:10 1998 Tim Janik <timj@gtk.org>
* gdataset.c: new file, gdatasets implement the object data
mechanism from GtkObject. a generic data pointer is associated with
a certain location and a key id.
Mon May 11 02:31:19 1998 Tim Janik <timj@gtk.org>
* gtk/gtkobject.h:
* gtk/gtkobject.c:
(gtk_object_data_try_key):
(gtk_object_data_force_id): these are now macros substituting the old
functions. we just use the corresponding g_dataset_* functions for
key->id associations. (this is to assure unique key<->id associations).
Sun Apr 12 20:09:40 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtklabel.[ch] (gtk_label_expose): Set a flag so
instead of clearing the area in advance. That looked
_really_ bad.
* gtk/gtkcontainer.c (gtk_container_class_init): Changed
"focus" to RUN_LAST.
* gtk/gtkentry.c (gtk_entry_realize): Fixed place
where allocation was used where requisition was meant.
(Found by David J N Begley <david@avarice.nepean.uws.edu.au>)

assertion in when setting default to NULL>
("Damon Chaplin" <DAChaplin@email.msn.com>)

default widget on the toplevel, if necessary.
Sun Apr 12 02:04:21 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkpreview.c: Removed unecessary and harmful
htons/ntohs when storing properties. (X does the byte
swapping itself)
Thu Apr 9 14:24:35 1998 Owen Taylor <owt1@cornell.edu>
(Found by Mattias.Gronlund" <Mattias.Gronlund@sa.erisoft.se>)
* gtk/gtkcurve.c (gtk_curve_interpolate): Added a
missing g_free.
* gtk/gtkcurve.c (gtk_curve_graph_events): Limits
were off by one, resulting in writing past array
bounds. Removed some unused code.
* gdk/gdk.c (gdk_dnd_drag_begin): The event structure
used for gdk_event_put should be a GdkEvent, not a
subtype, since it will all be copied.
* gtk/gtkcolorsel.c: Added a unrealize handler that
unref's the GC's that were created.
* gtk/testgtk.c (clist_warning_test): ref and sink
child because it may never be added to anything.
Tue Apr 7 19:36:48 1998 Owen Taylor <owt1@cornell.edu>
* gutils.c (g_direct_compare): Removed, because that's what
a NULL comparison function means. And it wasn't 64 bit safe.
Tue Apr 7 19:14:03 1998 Owen Taylor <owt1@cornell.edu>
* gdk/gdkpixmap.c: Added maximum field widths to prevent
possible '%s' scanf overflows. Replaced scanf("%c")
with getc(), Don't interpret /*/ as a full comment. Use
g_realloc/g_new.
* gtk/gtkwidget.h gtk/gtkprivate.h: Changed all flag
tests to check for ((GTK_WIDGET_FLAGS(widget) & FLAG) != 0)
instead of (GTK_WIDGET_FLAGS(widget) & FLAG)
* gtk/gtkfilesel.c: Use getwd() instead of getcwd() on
SunOS, because getcwd() hangs up in a wait4().
(Found by David Monniaux <monniaux@clipper.ens.fr>)
- Check device/inode/mtime not just inode/mtime, when
caching scanned directories.
(From: scottk@ig.utexas.edu (Scott Kempf))
* gdk/gdkpixmap.c: Check for 0 width/height when
creating pixmaps.
* gtk/*.c: Global substitution of recently introduced
"MAX (0," for allocations to "MAX (1,", since
creating a backing pixmap with a zero width or height
fails.
* gdk/gdkwindow.c (gdk_window_new): Don't set all the
WM properties for child windows. Don't set the base
size, since the value we set will be taken as a minimum
size.
Fri Mar 27 00:13:18 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkmain.c (gtk_propagate_event): If the widget is _not_
a descendant of a Window widget, propagate key presses like
other events.
* gtk/gtkentry.c gtk/gtktext.c: Ignore multiple simultaneous
button presses instead of treating subsequent presses as
release/press pairs for tablet compatibility.
* configure.in config.h.in: Removed inline checks, because they
are duplicated in glib.
* gtk/gtkwidget.c (gtk_widget_draw): When gtk_widget_draw ()
occurs with queued draw already in place, redraw _entire_
widget. (Pointed out by Tim Janik)
Thu Mar 26 21:37:57 1998 Tim Janik <timj@gtk.org>
* gtk/gtkradiobutton.c (gtk_radio_button_draw_indicator): always
display the correct active state.
* gtk/gtkcheckbutton.c (gtk_real_check_button_draw_indicator): always
display the correct active state.
* gtk/gtkwidget.c (gtk_widget_set_arg): CAN_FOCUS and CAN_DEFAULT flag
changes need to queue a resize.
* gtk/gtkbutton.c (gtk_button_paint): take border_width into
consideration for restrict area.
* gtk/gtktogglebutton.c (gtk_toggle_button_class_init): enable the
draw_default member of GtkButton, otherwise the diplay is messed up
for CAN_DEFAULT toggles.

is active or not.
* gtk/gtkwidget.c (gtk_widget_set_state):
(gtk_widget_set_sensitive):
(gtk_widget_set_parent):

want to change childrens states, or just restauration of old states.
Mon Mar 23 01:08:30 1998 Tim Janik <timj@gtk.org>
* gtk/gtkclist.c (gtk_clist_class_init): leave container_class->add and
container_class->remove untouched if we don't implement them.
* gtk/gtkcontainer.c (gtk_container_class_init): add missing NULL
initialization for the class method (*foreach). implement a default
handler to output a warning for (*add) and (*remove).

* gtk/gtkmain.c (gtk_init): fixes to locale checks
* gtk/testgtk.c (create_dnd): Create the dnd icons separately
to avoid strange interactions with shapes demo.

- Draw only the onscreen portion of the text to prevent wrapping
of shorts in the X drawing code.
- Keep track of character positions and x-offsets to speed
up algorithms.
Wed Mar 18 02:06:52 1998 Tim Janik <timj@gtk.org>
* gtk/gtkcontainer.c (gtk_container_border_width): use the resize queue.
* gtk/gtkwindow.c (gtk_window_set_arg): gtk_window_set_hints() after
setting certain arguments, so they actually take affect.
(gtk_window_set_policy): likewise.
Thu Mar 12 07:43:33 1998 Tim Janik <timj@gimp.org>
* gdk/gdk.h:
* gdk/gdkvisual.c: applied gtk-shige-980311-0.patch.gz, which removes
the erronerous gdk_query_visuals() function in favour of
gdk_list_visuals() which does a correct job.
* gtk/gtkcontainer.h: applied gtk-draco-980311-0.patch.gz which fixes
a class cast check.
* gtk/gtkspinbutton.c: applied gtk-hamann_jeske-980312-0.patch.gz about
'+' sign acceptance.
* gtk/gtknotebook.c: applied gtk-hamann_jeske-980311-1.patch.gz which
cares about delayed tab label creation.

* gtk/gtkentry.c gtk/gtkeditable.c gtk/gtkspinbutton.c:
Moved "activate" to editable class. Made the vfuncs in
gtkeditable just vfuncs not signals.

- Last position now always shares the property of the preceding
character
- Freeze the widget when inserting large amounts of text.
- Selecting lines now selects the _whole_ line.
- Fixed bug with displaying the cursor
- Ctrl-Home/End now move the cursor to the _absolute home/end
* gtkmenuitem.c: Remove necessary code out of a g_return_if_fail
-timj
Sun Mar 8 15:53:33 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c:
- Show selection correctly when starting selection with arrows
- Display pixmap background only when not editable
- Redraw focus area more carefully to prevent flashing (and
make style of drawing consistent with Entry)
* gtk/gtktreeitem.c: ref colormaps for pixmap by colormap
storage.
* gtk/gtkrc.c: Store a separate style for each RcStyle for
each colormap, so we can handle background pixmaps
correctly, which need to be per-colormap. (Leaks
colormaps...)
Parse text color style entries correctly.
* gtk/testgtk.c: insert text without fg color
gtk/testgtkrc: move "*" after rest, so the other class styles
take effect
* gdk/gdkwindow.c gdk/gdk.c gdk/gdkprivate.h: Send DND events
safely, in case drop window disappears. (Performance hit
because XSync()'s are necessary)
* gdk/gdk.h gdk/gdkpixmap.c: Added
gdk_pixmap_colormap_create_from_xpm[_d] to allow creating
pixmaps from xpm's before you have a GdkWindow.

editable and non-editable
* testgtk.c: Added a toggle button for editability for
the text widget.
Thu Mar 5 01:22:06 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkwidget.c (gtk_widget_unparent): Unset allocation
on unparent, to force reallocation if we get adding back
to a new parent which is already size-allocated.
* gtk/gtktreeitem.c: Keep track of separate +/- pixmaps
for each colormap, removed the idle hack.
* gdk/gdk.c: Don't warn when unable to open XIM method,
since X11R5 apparently has no default method.
* gtk/gtkwidget.c (gtk_widget_set_style_internal): Don't
call size_request on initial emission - since the
widget size isn't set yet, it can't change.
* gtk/Makefile.am: New rules 'test' and 'test-debug' to run
testgtk with the correct working directory.
* gtk/gtkentry.c (gtk_move_forward_word):
Check for position at end of line.
* gtk/gtkinputdialog.h (struct _GtkInputDialogClass):
removed 'gpointer data' arguments from default handler
structures.
Sun Mar 1 03:20:39 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkentry.[ch] gtk/gtktext.[ch] gtkeditable.[ch]
Turned off debugging in gtktext.c
Bug fixes for cutting, pasting, deleting, etc.
Some of the bugs that were there before have definitely
been fixed.
* gtk/testgtk.c gtk/testgtkrc: Removed my ugly orange backgrounds,
to make things look nicer.
Sat Feb 28 23:58:54 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkentry.[ch] gtktext.c gtkeditable.[ch]
Created a new base widget type Editable for the entry and
text widgets, which encapsulates most of the selection and
clipboard handling stuff, plus some common signals.
Changed the Entry widget extensively to support this,
but the interface and appearance should be the same.
Changed the Text widget moderately to support this.
It now supports:
- Selection style cut and paste
- Clipboard style cut and paste
- Emacs style key bindings (~same as Entry)
- Word motion
- "changed" signal
There are definitely still some bugs in the new stuff.
* gtkfilesel.c gtkspinbutton.c testgtk.c: small changes
to fit the new interface more exactly.
Fri Feb 27 15:31:55 1998 Tim Janik <timj@gimp.org>
* gtk/gtktipsquery.c: we make an active server grab now, this way we
can change the cursor globally and don't need to tweak event masks
of other windows.
* gtk/gtkframe.c (gtk_frame_style_set): recompute label size.
* gtk/gtkwidget.h:
* gtk/gtkwidget.c:
New signal GtkWidget::style_set to be emitted when a widget's style
changed. New flag GTK_RC_STYLE to indicate whether an rc lookup has
been perfomed for the widget.
(gtk_widget_ensure_style): New function.
(gtk_widget_set_rc_style): New function.
* docs/styles.txt: new file.
have the send_event field in all GdkEvents.
gtkmenu.c, gtkacceleratortable.c, gtkwindow.c: unreference accelerator_table.
gtk_object_query_args: removed seq_ids again, must have been quite tired
when i commited that change ;)
gtkoptionmenu.c: assure GTK_BIN()->child is empty when reparenting
a menu_items child.
gtkwindow.c: fixed some memory leaks.
-timj
Tue Feb 17 05:41:31 1998 Tim Janik <timj@gimp.org>
* gtk/gtkentry.c (gtk_entry_init): invoke gtk_entry_grow_text already
in this place, so the application will never see entry->text==NULL.
(see also ChangeLog entry from Tue Feb 11 1997 on this).
also i added some blurb about recent changes to the NEWS file,
and updated the TODO.
Tue Feb 3 15:09:55 1998 Tim Janik <timj@gimp.org>
* gtk/testgtk.c: don't add the same menu to different menuitems/
optionmenus.
* gtk/gtkmenuitem.h:
* gtk/gtkmenuitem.c: new function gtk_menu_item_remove_submenu ro
be consistent with optionmenu. use gtk_menu_attach_to_widget/
gtk_menu_detach for setting/removing the submenu.
invoke gtk_widget_destroy(submenu) in destructor to be consistent
with other destructors.
* gtk/gtkoptionmenu.h:
* gtk/gtkoptionmenu.c: attach/detach to menu widget via
gtk_menu_attach_to_widget/gtk_menu_detach.

and gtk_menu_detach that correspond to the action of
gtk_widget_set_parent and gtk_widget_unparent.
* gtk/widget.c: few fixups.
