2005-09-22 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkwidget.c (gtk_widget_class_init): Fix the documentation
for the grab-broken-event signal, noticed by Damon Chaplin.
2005-09-21 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkselection-win32.c (gdk_selection_convert,
gdk_text_property_to_text_list_for_display,
gdk_text_property_to_utf8_list_for_display,
gdk_win32_selection_add_targets,
_gdk_win32_selection_convert_to_dib): Free return value from
gdk_atom_name().
(gdk_text_property_to_text_list_for_display): Drop GError variable
that isn't actually used after being set.
2005-09-20 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkselection-win32.c
(gdk_selection_owner_get_for_display): Do return the correct owner
for CLIPBOARD (i.e., the owner of the Windows Clipboard, if it is
a window GDK knows about). The reason to return NULL seems to have
gone when in the fix for bug #163702 the artificial
GDK_SELECTION_CLEAR event generation was removed from
gdk_selection_send_notify_for_display(). Fixes bug #316552.
2005-09-19 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkiconview.c: Use g_list_nth_data() instead of g_list_nth()->data
in multiple places to avoid segfaults if the index is out of range.
(#316422, Guillaume Cottenceau)
2005-09-18 Hans Breuer <hans@breuer.org>
* gtk/gtktrayicon-win32.c : now handling events by hard-coded
g_signal_emit_by_name() - will break when gtkstatusicon.c changes.
2005-09-18 Hans Breuer <hans@breuer.org>
* gdk/gdk.symbols gdk/win32/gdkwin32.h gdk/win32/gdkcursorwin32.c : export
_gdk_win32_pixbuf_to_hicon() as gdk_win32_pixbuf_to_hicon_libgtk_only()
* gtk/gtktrayicon-win32.c : a lot of debug spew but it has started to show
the icon and is blinking with teststatusicon. More to come ...
2005-09-18 Hans Breuer <hans@breuer.org>
* gtk/makefile.msc.in : fix typo for GTK_VER; define HAVE_CONFIG_H
cause gtkprogressbar.c has #include <config.h> conditionally; less
noise from generated gtk.def
* gtk/stock-icons/makefile.msc gdk/makefile.msc tests/makefile.msc : updated
* gtk/gtktrayicon-win32.c : dummy implmentation to make gtk compile.
For me it works as well as the *NIX implemenation, that is not at all.
* gdk/win32/gdkproperty-win32.c : implement gdk_atom_intern_static_string()
* gdk/win32/gdkwindow-win32.c(gdk_window_set_urgency_hint) : only use
only use (WINVER >= 0x0500) when available from the SDK. Otherwise fall
back to true dynamic linking of FlashWindowEx. Makes gtk+ work on NT4.0
again - if compiled properly.
* tests/teststatusicon.c : don't use GNOME icons for testing, but icons
already coming with Gtk+. Makes it compile on win32.
2005-09-16 Tor Lillqvist <tml@novell.com>
* modules/engines/ms-windows/msw_style.c (draw_extension,
draw_box_gap): Check whether the widget actually is a GtkNotebook
before treating it as such. Drop some unneeded local variables,
use parameter with same information instead. (#316412)
2005-09-15 Federico Mena Quintero <federico@ximian.com>
* tests/autotestfilechooser.c: Start a set of automated tests for
the file chooser. The only test in there right now doesn't pass
yet. It specifies the intended behavior of the first optimization
of a series which I'll do on the file chooser (see
http://primates.ximian.com/~federico/news-2005-09.html#14 for the
details of this optimization).
* tests/Makefile.am: Added autotestfilechooser.c.
* gtk/gtkfilechooserprivate.h (struct
_GtkFileChooserDialogPrivate): Move all the file chooser's private
structures to here, so that they can be accessed by
tests/autotestfilechooser.c: _GtkFileChooserDialogPrivate,
_GtkFileChooserWidgetPrivate, LoadState, _GtkFileChooserDefault.
* gtk/gtkfilechooserdialog.c: See above.
* gtk/gtkfilechooserwidget.c: See above.
* gtk/gtkfilechooserdefault.c: See above.
Thu Sep 15 15:27:55 2005 Tim Janik <timj@imendio.com>
* gtk/gtkwindow.c:
gtk_window_map_event(): new function to work around lost unmap requests.
fixes bug #316180.
2005-09-14 Federico Mena Quintero <federico@ximian.com>
* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_init): Add
an easy-to-find profiling marker when starting to create a file
chooser.
(browse_files_model_finished_loading_cb): Likewise, for when the
chooser is finished loading.
2005-09-14 Matthias Clasen <mclasen@redhat.com>
* gtk/gtklabel.c (gtk_label_get_type):
* gtk/gtkbutton.c (gtk_button_get_type):
* gtk/gtkwindow.c (gtk_window_group_get_type): No point in
using a mem chunk for window groups, buttons, labels.
2005-09-13 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkimcontextsimple.c (gtk_im_context_simple_filter_keypress):
Let GDK_Return pass through in some more cases.
* gtk/gtkentry.c (gtk_entry_key_press): Reset the im context before
activating the entry.
2005-09-09 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkcellrendererkeys.h:
* gtk/gtkcellrendererkeys.c: Add a cell renderer for displaying
and editing accelerators, a port of EggCellRendererKeys .
* gtk/gtk.symbols:
* gtk/gtk.h:
* gtk/Makefile.am: Add the keys cell renderer.
* tests/Makefile.am:
* tests/testkeys.c: Test GtkCellRendererKeys
2005-09-09 Matthias Clasen <mclasen@redhat.com>
Make it possible to determine if a key event is for a
modifier key:
* gdk/x11/gdkprivate-x11.h:
* gdk/x11/gdkkeys-x11.c (_gdk_keymap_key_is_modifier):
New function to determine if a keycode is mapped to a modifier.
(get_xkb): Get the modmap.
* gdk/x11/gdkevents-x11.c (translate_key_event): Set the
is_modifier bit by calling _gdk_keymap_key_is_modifier().
* gdk/gdkevents.h (struct _GdkEventKey): Add an is_modifier
bit.
2005-09-09 Matthias Clasen <mclasen@redhat.com>
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_button_event):
Make drag reordering work properly for columns other than the
first. (#315054, Dan Winship)
2005-09-09 Matthias Clasen <mclasen@redhat.com>
Stop cursor blinking in non-editable regions of a text view.
(#311508, Torbjörn Andersson)
* gtk/gtktextview.c (gtk_text_view_check_cursor_blink):
(cursor_blinks): Take editability into account when deciding
whether the cursor blinks.
(gtk_text_view_button_release_event):
(gtk_text_view_move_cursor_internal): Update cursor blinking here.
2005-09-09 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkcalendar.c (gtk_calendar_init): first_weekday is relative
to week_1stday, not to Sunday. Gotta love the ISO 14652 guys...
(#314473, Stanislav Brabec)
2005-09-09 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c (gdk_display_get_name): Cache the
display name. There is only one GdkDisplay on Win32, and
constructing the display name isn't entirely trivial, so cacheing
is probably worth it. For instance GIMP calls this function a lot.
(gdk_display_open): Call gdk_display_get_name() to prime the
cached name.
(gdk_display_get_n_screens, gdk_display_get_screen,
gdk_display_get_default_screen): Verify parameter correctness like
the X11 backend does.
* gdk/win32/gdkscreen-win32.c (gdk_screen_make_display_name):
Return a freshly allocated string, as the API specifies. Fixes a
heap corruption problem that caused random errors and crashes in
GIMP, for instance.
2005-09-07 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkimcontextsimple.c (gtk_im_context_simple_filter_keypress):
Make C-u commit and restart hex input if we are already in a
hex sequence.
2005-09-06 Matthias Clasen <mclasen@redhat.com>
* gdk/x11/gdkkeys-x11.c (update_modmap): Make the modmap reflexive.
(_gdk_keymap_add_virtual_modifiers): Don't add both Alt and Meta
if they are mapped to the same modifier.
2005-09-06 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkaccelgroup.c (gtk_accelerator_parse):
* gtk/gtkaccellabel.c (_gtk_accel_label_class_get_accelerator_label):
Don't use GDK_ALT_MASK.
* gdk/gdktypes.h: No need to introduce GDK_ALT_MASK
2005-09-06 Matthias Clasen <mclasen@redhat.com>
* tests/testgtk.c (create_key_lookup): Add tests for extra virtual
modifiers.
* gtk/gtkkeyhash.c (_gtk_key_hash_lookup): Try to match both against
Mod2 - Mod5 and against Super, Hyper, Meta.
* gtk/gtkaccellabel.c (_gtk_accel_label_class_get_accelerator_label):
* gtk/gtkaccelgroup.c (gtk_accelerator_parse)
(gtk_accelerator_name): Support Super, Hyper Meta and Mod2 - Mod5.
2005-09-06 Matthias Clasen <mclasen@redhat.com>
Add support for extra virtual modifiers: (#85780, Owen Taylor)
* gdk/x11/gdkkeys-x11.c (struct _GdkKeymapX11): Add a
modmap to maintain the information which X modifiers map to
virtual modifiers.
(get_xkb): Set up the modmap from the XKB tables.
(update_keymaps): Set up the modmap from the information returned
by XGetModifierMapping in the non-XKB case.
* gdk/x11/gdkprivate-x11.h:
* gdk/x11/gdkkeys-x11.c (_gdk_keymap_add_virtual_modifiers): New
function to set the virtual modifiers in the state.
* gdk/x11/gdkevents-x11.c (translate_key_event): Call
_gdk_keymap_add_virtual_modifiers here.
* gdk/gdktypes.h (GdkModifierType): Add bits for virtual Super,
Hyper and Meta modifiers. Also add GDK_ALT_MASK as an alias
for GDK_MOD1_MASK.
2005-09-05 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkaction.c (connect_proxy): Set the label of a button
if it has no child. (#315253, John Finlay)
2005-09-02 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkentry.c (gtk_entry_destroy): Disconnect idle handlers
on destroy to avoid problems when they are called on a destroyed
widget. (#315135, John Cupitt)
2005-09-02 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkimcontextsimple.c: Rework the Unicode hex input
code. Now we only steal a single key combination, Ctrl-Shift-U,
instead of sixteen.
A hex Unicode sequence must be started with Ctrl-Shift-U, followed
by a sequence of hex digits entered with Ctrl-Shift still held.
Releasing one of the modifiers or pressing space while the modifiers
are still held commits the character. It is possible to erase
digits using backspace.
As an extension to the above, we also allow to start the sequence
with Ctrl-Shift-U, then release the modifiers before typing any
digits, and enter the digits without modifiers.
(#82011, Owen Taylor)
2005-09-02 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkmain.c (gtk_get_event_widget): If the window is destroyed,
we still need to deliver the destroy event. (#314980, Chris Lahey)
2005-09-02 Alexander Larsson <alexl@redhat.com>
* gtk/gtkfilechooserdefault.c: (shortcuts_add_volumes),
(shortcuts_activate_volume):
Handle base_path being null in the rest of the cases (#310270)
2005-09-02 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkevents-win32.c (gdk_event_translate): Keep track of
cursor position also in root window coordinates. Prune out
superfluous WM_MOUSEMOVE messages even earlier, based on root window
coordinates. Windows sends WM_MOUSEMOVE messages after a new
window has ben mapped below the cursor even if the mouse doesn't
move. We used to generate GDK_MOTION_NOTIFY in these cases. This
confused at least gtk_menu_motion_notify(). (#314995)
* gtk/gtkintl.h: No need to include config.h here. It caused
warnings about GTK_LOCALEDIR being redefined on Win32 when
compiling files where gtkintl.h is included after gtkprivate.h
(which #undefines and re-#defines GTK_LOCALEDIR on Win32).
* gtk/gtkplug.c: Include config.h.
2005-09-01 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkfilesystemunix.c: Pass statbufs down to
xdg_mime_get_mime_type_for_file() where possible, to avoid
useless re-stating.
2005-09-01 Matthias Clasen <mclasen@redhat.com>
* gdk/*.c: Intern some more strings.
* gtk/gtkintl.h:
* gtk/*.c: Define an I_() macro and use it instead of the
bulky g_intern_static_string().
2005-08-31 Matthias Clasen <mclasen@redhat.com>
* gdk/Makefile.am:
* gtk/Makefile.am: Intern type names in code generated by
glib-mkenums, too.
* gtk/*.c:
* gdk/x11/*.c:
* gdk/*.c: Intern type names before registering the type to avoid
unnecessary copies.
2005-08-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkentry.c (gtk_entry_class_init): Add key bindings to
make C-/ select all and C-\ unselect all. (#309301,
Kathy Fernandez)
2005-08-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkimcontextsimple.c: Change the compose sequence for
soft hyphen to be multi_key-minus-minus-space, and add
compose sequences multi_key-minus-minus-period and
multi_key-minus-minus-minus for en dash and em dash.
(#172653, Christian Lohmaier)
2005-08-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkuimanager.c (gtk_ui_manager_class_init): Another
fix for the default value of the "ui" property.
2005-08-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtk.symbols:
* gtk/gtkselection.h:
* gtk/gtkselection.c: Add functions which look for text, image
or uri targets in an array of atoms. (#314089, Mark Wielaard)
2005-08-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtk.symbols:
* gtk/gtkwindow.h:
* gtk/gtkwindow.c: Add a deletable property with getter
and setter, to control the close button in the window
frame. (#59718, Havoc Pennington)
2005-08-29 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkrc.key.emacs: Add C-n/C-p/C-f/C-b as alternatives
to the arrow keys for menu navigation. (#162825, Carl Worth)
2005-08-29 Matthias Clasen <mclasen@redhat.com>
Add a cross-platform "tray icon" API, by
porting EggStatusIcon/EggTrayIcon (#105101)
* gtk/gtkstatusicon.h: A GtkStatusIcon is an object which
displays an icon in a notification area.
* gtk/gtkstatusicon-x11.c: GtkStatusIcon implementation for
X11, using GtkTrayIcon.
* gtk/gtktrayicon.h:
* gtk/gtktrayicon.c: An implementation of the freedesktop.org
system tray specification, not public API.
* gtk/gtk.symbols: Add new exported functions.
* gtk/gtk.h: Include gtkstatusicon.h.
* gtk/Makefile.am: Add new files.
* tests/Makefile.am:
* tests/teststatusicon.c: Test for GtkStatusIcon.
2005-08-29 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkmenu.c (gtk_menu_grab_notify): Only cancel if the menu
was active. (#314298, Christian Persch, analysis by Mark McLoughlin)
2005-08-26 Matthias Clasen <mclasen@redhat.com>
* configure.in: Bump version to 2.9.0
* gdk-pixbuf/gdk-pixbuf.sgml:

symbols in 2.10
2005-08-26 Matthias Clasen <mclasen@redhat.com>
* gdk/gdk.symbols:
* gdk/gdkscreen.h:
* gdk/gdkscreen.c: Make the GdkScreen font options api
public, and add properties GdkScreen::font-options and
GdkScreen::resolution. (#314004)
* gdk/gdkpango.c:
* gtk/gtksettings.c:
* gtk/gtkwidget.c: Adjust all callers.
* gdk/gdkintl.h: Simplify and use glib/gi18n-lib.h.
* gdk/gdkpango.c: Include gdkintl.h, not gtkintl.h.
* gdk/gdkscreen.c: Include gdkintl.h.
2005-08-26 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkicontheme.c (theme_lookup_icon): Avoid an uninitialized
variable warning, pointed out by Colin Walters. (#314585)
2005-08-25 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkmenutoolbutton.c (menu_position_func): Take widget
y offset into account when positioning the popup. (#314470,
Christian Persch)
2005-08-25 Owen Taylor <otaylor@redhat.com>
* gdk/gdkscreen.c (gdk_screen_get_type): Use gdk_screen_init
as instance_init, not base_init! (Fix from Frederic Crozat,
reported by Joe Marcus Clarke). Trivial cleanup: use -1.
rather than -1 for a negative flag value.
2005-08-24 Matthias Clasen <mclasen@redhat.com>
* gtk/gtksettings.c (gtk_settings_get_for_screen): Make sure font
and cursor settings get propagated down to the screen initially.
Pointed out by Frederic Crozat.
2005-08-24 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkicontheme.c (ensure_valid_themes): Don't try to send a client
message if the screen is NULL. Noticed by Kjartan Maraas.
2005-08-23 Owen Taylor <otaylor@redhat.com>

* gdk/gdk.symbols:
* gdk/gdkscreen.[ch]: Add gdk_screen_get/set_font_options_libgtk_only()
Add gdk_screen_get/set_resolution_libgtk_only()
* gdk/gdkpango.c (gdk_pango_context_get_for_screen): Set
the options for the screen on the newly created context.
* gtk/gtksettings.c (settings_update_font_options/dpi) gtkwidget.c:
Move font options and dpi code from gtkwidget.c to gtksettings.c, set
the font options on the screen.
* gtk/gtkwidget.c (gtk_widget_update_pango_context): Just get
the font options from the screen and set them on the context.
2005-08-23 Kristian Rietveld <kris@gtk.org>
* gtk/gtktreemodelsort.c (gtk_tree_model_sort_row_inserted): don't
bother inserting new rows in a level with a zero refcount and
immediately free the level. (Fixes#312350, reported by Markku Vire).
2005-08-23 Matthias Clasen <mclasen@redhat.com>
* gtk/updateiconcache.c: Complain when there is no index.theme file
in the specified directory, unless --force is used. Also add an
--index-only option to create caches without image data.
2005-08-23 Matthias Clasen <mclasen@redhat.com>

* gtk/gtkicontheme.c (ensure_valid_themes)
(_gtk_icon_theme_check_reload): Implement a clientmessage based
scheme for makeing sure that all GTK+ applications notice if an
icon theme has been updated. This should prevent multiple versions
of an icon theme cache to be mapped in memory at the same time,
which can cause excessive memory consumption. (#313156, Chris
Lahey)
2005-08-22 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkicontheme.c (gtk_icon_theme_load_icon): Add a note
regarding icon theme changes.
* gtk/gtkiconcache.c (_gtk_icon_cache_get_icon): When returning
pixbufs which are backed by the mmapped memory of an icon cache,
increase the refcount of the icon cache, so that the memory is not
munmapped away underneath the pixbuf upon icon theme changes.
(#314170, Kjartan Maraas)
Sat Aug 20 16:12:14 2005 Jonathan Blandford <jrb@redhat.com>
* gtk/gtktreeview.c (gtk_tree_view_set_model): clear

(gtk_icon_view_scroll_to_path): Handle scrolling to a path before
we're realized, #312798
(gtk_icon_view_set_model): clear scroll_to_path if the model
changes.
2005-08-20 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkrange.c (gtk_range_adjustment_changed)
(gtk_range_adjustment_value_changed): Don't queue a draw
if the layout has not changed. (#313991, Benjamin Berg)
2005-08-19 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkmain.c (gtk_get_event_widget): Don't access
the user data on destroyed windows, since at best
it can be a stale pointer. (#313953, Robin Green)
2005-08-19 Matthias Clasen <mclasen@redhat.com>
* gtk/gtktreeview.c (gtk_tree_view_get_visible_range): Return

* gtk/gtkicontheme.c (theme_lookup_icon): Store GtkIconData structs
in the per-directory hash, even if they come from the icon cache.
We tried to avoid that before, but as a result leaked icon data
structs. (#313852, Kjartan Maraas)
2005-08-18 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkmenutoolbutton.c (gtk_menu_tool_button_destroy): Disconnect

FcNameConstant(). (More of #313417)
2005-08-15 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkfilechooserdefault.c: When using gtk_dialog_run() for
modal dialogs, make sure to inherit the window group from

transient parents currently. (#312918, Christian Persch)
* gtk/gtkmessagedialog.c (gtk_message_dialog_new):

#153870, Christian Persch, Paolo Borelli)
2005-08-15 Matthias Clasen <mclasen@redhat.com>
* gtk/gtksizegroup.c: Use object data to mark widgets and
groups as visited, so that we avoid constant extra list
traversals. Also allocate quarks in class_init. (#311618,
Michael Natterer)
2005-08-14 Matthias Clasen <mclasen@redhat.com>
* gtk/updateiconcache.c: Store only one copy of the pixel data
for symlinked icons. To achieve this, maintain a hashtable
mapping pathnames to pixel data, and share the pixel data for
all symlinks resolving to the same pathname. When writing out
the image data, write out the pixel data only the first time
it is met, and store the offset pointing to the first copy
for use in all later cases.
This reduces the size of the Bluecurve icon cache from 40
to 13MB. (#312972)
