* gdk/gdk.c gdkprivate.h: Added a modular client-message-filter
mechanism, that is used for the DND messages.
Removed all the old DND code.
* gdk/gdkcolormap.c gdk/gdkcolormap.h: Add a function to
get the visual of a given colormap.
* gtk/gtkcolorsel.c: Conversion to new DND, drag
a color-swatch.
* gdk/gdk.h gdk/gdkdnd.c: The low-level
X oriented portions of drag and drop protocols.
Sending and receiving client messages, and navigating
window trees.
* gdk/gdkimage.c: added a gdk_flush() when destroying
SHM images to hopefully make it more likely that
X will gracefully handle the segment being destroyed.
* gdk/gdkprivate.h gtk/gtkdebug.h: Add new
DND debugging flags.
* gtk/gtkeditable.[ch]: Updates for the selection handling
changes.
* gtk/gtkselection.[ch]: Added GtkTargetList, a
refcounted data structure for keeping track of lists
of GdkAtom + information. Removed selection_handler_add
in favor of a "drag_data_get" signal.
* gtk/gtkdnd.[ch] gtk/gtk.h: New files - highlevel (event loop
dependent) parts of the DND protocols, display of drag icons,
drag-under highlighting, and the "default handlers".
* gtk/gtkinvisible.[ch]: New widget - InputOnly offscreen
windows that are used for reliable pointer grabs and
selection handling in the DND code.
* gtk/testdnd.c: New test program for new DND. (Old
DND tests in testgtk still need to be converted.)
* gtk/testselection.c: Use the new selection API.
* docs/dnd_internals: Start at describing how
all the new code works inside.
* docs/Changes-1.2.txt: New file describing source-incompatible
changes in GTK+-1.2.
Sat Oct 17 22:50:34 1998 Owen Taylor <otaylor@gtk.org>
* gdk/gdkwindow.c (gdk_window_remove_filter): Free
the right list node.
* gdk/gdkwindow.c (gdk_window_init): Add gdk_root_parent
to the XID table so we can receive events on it.
Wed Oct 14 12:57:40 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdk.c gdk/gdk.h (gdk_event_get_time): New function
to get the timestamp from a generic event.
Fri Oct 9 13:16:04 1998 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.c (gtk_widget_add_events): Added function
that safely adds additional events to a widget's event
mask, even if the widget has previously been realized.
(We can do this, but not remove events from the event
mask).
Fri Oct 2 17:35:35 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdkproperty.c (gdk_property_get): Allow type == 0,
for AnyPropertyType.
Fri Oct 2 10:32:21 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdkproperty.c (gdk_atom_intern): Add client-local
hashing.
Thu Sep 24 20:33:54 1998 Owen Taylor <otaylor@redhat.com>

isn't a timestamp.
Thu Sep 17 14:23:03 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdk.c (gdk_event_translate): Removed printing
of unknown window lookup warnings. (Made it
a GDK_NOTE) - they happen in many circumstances.
Wed Oct 7 05:15:36 1998 Tim Janik <timj@gtk.org>
* gtk/gtk*.h:
* gdk/gdk.h: removed all occourances of #pragma } and #pragma {
which were in place to fixup emacs' cc-mode indentation.
putting (c-set-offset 'inextern-lang 0) into ~/.emacs is the
proper way to achive this and doesn't produce problems for
stupid pragma-related compiler bugs. ;)
Sat Sep 25 23:33:55 1998 Tim Janik <timj@gtk.org>
* gdk/gdkwindow.c (gdk_window_get_root_origin): new function to get
the *real* geometry position of a window, taken possible window
manager offsets into account.
this has been succesfully tested with fvwm, fvwm-2, bowman, olwm,
olvwm, twm, ctwm, mlvwm, windowmaker and enlightenment.
it does fail though for amiwm which adds windows to a pseudo root
window, and for icewm by a small offset because it defines the
geometry position whithin its border.
* gtk/testgtk.c: added "saved position" test to figure how
gdk_window_get_root_origin() interacts with window managers (repopup
this window to figure ;).
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.
Tue Jul 21 12:42:01 1998 Owen Taylor <otaylor@redhat.com>
* gdk/gdk.h gdk/gdkfont.c: Added gdk_text/string_extents() -
too calculate all the metrics at once of a string, including
things which weren't calculated before.
* gtk/Makefile.am gtk/gtk.h gtk/gtktearoffmenu.[ch]: New
MenuItem type, that when put as the first thing in a
menu, makes the menu tearoff. Currently drawn as a
dashed line.
* gtk/gtkmenuitem.h gtk/gtkcheckmenuitem.c: Added a flag
"hide_on_activate" to the MenuItem class structure to allow
check and radio buttons to be changed with <Space> without
hiding the menu.
* gtk/gtkaccellabel.[ch]: Added new capabilities to set
a underline_group and underline_mods for the label -
accelerators added in the underline group matching
underline_mods will be displayed as an underline character.
This doesn't work - Save As needs to be underlined
as Save _As.
* gtk/gtkitemfactory.c:
- Create a AccelGroup for each MenuShell we create.
- If an '&' appears before a character 'c' in the path,
then make 'c' an accelerator in the menu's accel group,
and if the menuitem is menubar <alt>C an accelerator
in the itemfactory's accel group.
* gtk/gtklabel.[ch]: Add support for a pattern arg -
which is a string. If an '_' appears in this string,
the corresponding position in the label is underlined.
Add gtk_label_parse_uline() convenience function which
takes a string with embedded underlines, sets the
pattern and label, and returns the accelerator keyval.
* gtk/gtkmenu.[ch]: Make menus no longer a toplevel widget.
Instead, they create a GtkWindow and add themselves
to that. (When torn off, another new feature, they
create another GtkWindow to hold the torn off menu)
New function gtk_menu_set_tearoff_state()
* gtk/gtkenums.h gtk/gtkmenushell.[ch] gtk/gtkenums.h:
Added action signals for keyboard navigation of menus.
* gtk/gtkmenushell.c: Key press handler which activates
bindings for navigation, and accelerators, for handling
underline accelerators. Exported functions to select
and activate menu items in a menushell.
* gtk/testgtk.c: Added a new "Item Factory" test which
tests GtkItemFactory and the new keyboard navigation
of menus.
Thu Jun 25 10:50:34 1998 Stefan Jeske <stefan@gtk.org>
* gdk/gdk.h gdk/gdkfont.c: Added functions gdk_text_height,

* gdk/gdk.h:
* gdk/gdkwindow.c: new function gdk_window_at_pointer() to retrive
the current GdkWindow the pointer is on if there is any.
* gtk/gtktable.c (gtk_table_init): preallocate a table with one row
and one column, so we don't construction logic at all. changed a few
(x < y - 1) to (x + 1 < y), to avoid failing evaluations due to
unsigned int wraps.
* gtk/gtkwidget.c (gtk_widget_set_parent): removed left over code
portion, added an additional check for parent != widget.
* more GtkType and macro fixups.
Tue Jun 9 18:44:57 1998 Owen Taylor <otaylor@gtk.org>
* gtk/gtkobject.c: Removed g_object_pointer_hash, which
was just g_direct_hash.
Mon May 25 19:54:20 1998 Owen Taylor <otaylor@gtk.org>
* configure.in: x_libs=, not $x_libs=. Enough said.
(Case only hit for --disable-xshm)
Mon May 25 12:08:14 1998 Owen Taylor <otaylor@gtk.org>
* configure.in (LDFLAGS): Add to $CFLAGS and $LDFLAGS
when testing for X libraries, don't replace them. Because
the user might have specified the path to the X libraries
themself before running configure.
* examples/**.c: Changed all gpointer * to gpointer
Sat May 23 21:54:05 1998 Owen Taylor <otaylor@gtk.org>
* configure.in (LDFLAGS): Bomb out with a moderately
helpful message if detection of X libraries fails.

* glib.h ghash.c gstring.c gdataset.c gutils.c:
- Added new typedef g_const_pointer; expunged all incorrect
uses of 'const gpointer'.
- Fixed up warnings that that created,
- Changed GHashFunc and GCompareFunc to take g_const_pointer
arguments. (Necessary, but will cause warnings in existing
code until fixed)
- Added other new const in harmless positions.

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.

* gtk/gtkrc.[ch]: New function gtk_rc_reparse_all() which
rereads all previously read RC files.
* gdk/gdkwindow.c gdk/gdk.h: New function gdk_window_get_toplevels().
(Should it just be called gdk_get_toplevels?)

* 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

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)

Thu Feb 19 01:11:48 1998 Owen Taylor <owt1@cornell.edu>
* configure.in gdk/gdk.[ch] gdk/gdkcc.c
gdk/gdkglobals.c gdk/gdkinputcommon.h gdk/gdkprivate.h
gdk/gdkvisual.c glib/configure.in glib/glib.h
glib/gutils.c gtk/Makefile.am gtk/gtkmain.c
gtk/gtkobject.[ch] gtk/gtkdebug.h docs/debugging.txt
New system for controlling debugging:
* --enable-debug=[no/yes/minimum]
* G_DISABLE_ASSERT and G_DISABLE_CHECKS for glib
* G_NO_CHECK_CASTS to control cast checking
* G_ENABLE_DEBUG enables run time checking which controls:
Object tracing
Showing events
Miscellaneous g_print's in GDK
And is controlled by --gdk-debug/GDK_DEBUG, --gtk-debug/GTK_DEBUG
* debug_level and show_events are gone from GTK
See docs/debugging.txt for details.
And some fixups to the configure.in's so '-g' can be
overriden on the command line for --enable-debug
Thu Feb 12 23:59:49 1998 Owen Taylor <owt1@cornell.edu>
* 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.
Mon Dec 29 22:05:45 1997 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gdk/gdkgc.c (gdk_gc_copy): New function, used to copy the values
from one gc to another gc.
It compiles and links, but is *completely* untested. Feel free to
pound on it.
The idea is to do all color management (allocation, etc.) via a
GdkColorContext so that apps will be friendly to 8-bit displays.
GdkColorContext is supposed to work on all visual/depth combinations.
This support, however, is lacking from the rest of Gdk/Gtk. I will
try to work on that.
- Federico
* gdk/gdk.c, gdk/gdk.h, gdk/gdktypes.h:
Remove dependencies of interfaces on USE_XIM
* gdki18n.h: Attempt to make wchar handling more portable
* gdkwindow.c: Include config.h. (For gdkinput.h)
Takashi Matsuda <matsu@arch.comp.kyutech.ac.jp>
TANAKA Shinya <shinya@race.u-tokyo.ac.jp>
See ChangeLog entries for further details.
Also some small fixes to event handling in gdk/gdk.c; sending
clear events in gtk/gtkselection.c and cut-and-paste in
gtk/gtkentry.c
