incorrect cast.
Sun Sep 2 23:27:16 2001 Kristian Rietveld <kristian@planet.nl>

it working. It mostly works now, although there're still a few issues
to be worked out.

application for the GtkTreeModelSort.
Sun Sep 2 23:19:07 2001 Kristian Rietveld <kristian@planet.nl>

* gtk/gtktextbuffer.[ch] (gtk_text_buffer_add/remove_selection_clipboard):
Instead of always mirroring the selection to a single PRIMARY
selection, allow it to be mirrored to any number of clipboards.
* gtk/gtktextbuffer.[ch] (gtk_text_buffer_paste_primary): Remove,
just use gtk_text_buffer_paste_clipboard with the appropriate clipboard.
* gtk/gtktextbuffer.[ch] (gtk_text_buffer_cut/copy/paste_clipboard): Add a
GtkClipboard argument, and for paste_clipboard, the

update to reflect GtkImage changes
* gdk/x11/gdkwindow-x11.c (gdk_window_set_icon_list): don't check

(gtk_window_get_icon_list)
(gtk_window_set_icon)
(gtk_window_get_icon)

only in response to an area_prepared signal.
Mon Aug 27 22:00:41 2001 Manish Singh <yosh@gimp.org>
* gtk/gtkradiobutton.c: fix silly cut'n'paste error,
with_label and with_mnemonic should create radio buttons, not
check buttons
Mon Aug 27 15:18:14 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtktreeselection.c (gtk_tree_selection_set_mode): Use the
GTK selection types rather than GtkTreeSelectionMode.
* docs/Changes-2.0: Add comment about selection change.
Mon Aug 27 14:18:12 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenubar.h (gtk_menu_bar_prepend): Fix a cuple
of typos in compat macros. (#59624, Skip Montaro)
Sun Aug 26 20:00:00 2001 Owen Taylor <otaylor@redhat.com>

macro.
(patch from ERDI Gergo <cactus@cactus.rulez.org>, #58920)
* gtk/gtkmenuitem.c (gtk_menu_item_set_right_justified): Change
interface to be a standard setter from gtk_menu_item_right_justify.
(gtk_menu_item_get_right_justified): a getter to go with the setter

gtk_menu_item_right_justify.
* demos/gtk-demo/menus.c tests/testgtk.c: Switch to
gtk_menu_item_set_right_justified.
2001-08-27 Jens Finke <jens@gnome.org>
* gtk+.spec.in: Updated to match gpp requirements, reworked the
files section to make it work with 1.3.x releases.
2001-08-26 Alexander Larsson <alla@lysator.liu.se>
* gtk/gtkbutton.[ch]:
Add properties for labels, mnemonics and stock items.
Added C accessor functions for the properties.
Removed deprecated button->child.
* gtk/gtkradiobutton.c:
* gtk/gtktogglebutton.c:
Update to use the functions in GtkButton.
* gtk/gtkcheckbutton.c:
Update to use the functions in GtkButton.
Changed size allocation of child. Now only gets as much
space as it requests.
* gtk/gtkclist.c:
Don't use GtkButton->child
* gtk/gtklabel.c:
Fixed typo in docs
2001-08-26 Alexander Larsson <alla@lysator.liu.se>
* tests/testgtk.c:
* tests/Makefile.am:
Ressurect the properties test.
I don't care if it is inferior, I just want to test my property code.
2001-08-25 Chema Celorio <chema@celorio.com>
* gtk/gtktable.c (gtk_table_set_child_property): pass ->nrows to
gtk_table_resize as the first argument for CHILD_PROP_RIGHT_ATTACH
and CHILD_PROP_LEFT_ATTACH v.s. using ->ncols
2001-08-24 Havoc Pennington <hp@pobox.com>
* gtk/gtkcompat.h: remove gtk_menu_* compat defines;
these are already in gtkmenu.h, and the copies
here were broken.
Also, change GTK_DISABLE_COMPAT_H to GTK_DISABLE_DEPRECATED
* gdk/gdkpixbuf-drawable.c (gdk_pixbuf_get_from_image):
special-case bitmaps to allow no colormap
(bitmap1): implement no-colormap bitmap-getting
(bitmap1a): implement no-colormap bitmap-getting to pixbuf with
alpha
(rgb8): indentation
(rgb1a, rgb1): change the way we read the data out of the image,
old way didn't seem to work quite right.
I'm pretty sure a lot of the rgbconvert code is still broken.
* gtk/gtkwindow.c (gtk_window_move_resize): move hints comparison
above position constraint (I really intended to do this before,
don't know what's up with that)
(gtk_XParseGeometry): shut up gcc
* gdk/gdkpixbuf-drawable.c (rgb1a): fix bug where "x1" was used
and "0" should have been. remove the attempted 4-bytes-at-once
optimization, it was totally broken.
Sat Aug 25 19:02:39 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkbutton.[ch] gtk/gtktogglebutton.c: Add optional movement
on push to buttons (based on patch from Soeren Sandmann, #54720)
- Add child_displacement_x/y style properties to control how far the
child moves when the button is depressed.
- Add non-exported function _gtk_button_set_depressed to clean
up the handling of the in/out shadow and separate it frmo
widget->state.
- Lots of code cleanup and simplification of state handling
for GtkButton/GtkToggleButton.
* tests/testgtkrc: Set the x/y displacement to 1 to provide a test
of button movement. testgtk + testgtkrc == test ugly GTK+, as always.
Fri Aug 24 23:09:05 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkimage.[ch] docs/Changes-2.0.txt: Break compatibility
and make gtk_image_new() take no arguments. The compiler will
catch it, and it is vastly more useful than having
gtk_image_new() be a deprecated alias for gtk_image_new_from_image().
* gtk/gtkmenu.c (gtk_menu_set_property): Apply patch
to add tearoff-title property (#51319, Lee Mallabone)
Fri Aug 24 22:12:32 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenuitem.[ch]: Remove unused and useless function
gtk_menu_item_configure(). (#58925)
Fri Aug 24 16:03:45 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtktreeview.c (gtk_tree_view_scroll_to_cell): Add
"use_align" to give people the option to just make a cell visible.
* gtk/gtktreeview.c (gtk_tree_view_scroll_to_point): fix bug where
we were scrolling past the end of the tree.
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_pack_start):
rename gtk_tree_view_column_pack_start_cell_renderer to
gtk_tree_view_column_pack_start. Same for pack_end, and clear.
Fri Aug 24 12:02:08 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtktextbuffer.c (gtk_text_buffer_new): Remove
a stray g_object_ref() left over from gtk_object_ref/sink.
(Pointed out by Josh Pritikin.)
Thu Aug 23 19:10:01 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenubar.h (gtk_menu_bar_insert): Deprecate
gtk_menu_bar_append/prepend/insert, forgot to do this
when we deprecated gtk_menu_append/prepend/insert.
* gtk/gtkmenu.h (gtk_menu_insert): Add casts to deprecated
compat macros.
* gtk/gtkmenu.c: Fix problem with static gtk_menu_insert() being
renamed by compat macro.
* gtk/gtkfontsel.h: Deprecated gtk_font_selection_get_font(),
gtk_font_selection_dialog_get_font(). (Suggested by
Vitaly Tishkov, #59383)
Thu Aug 23 18:23:31 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtktexttag.c (gtk_text_tag_table_get_size):
Rename from gtk_text_tag_table_size(). (#59366)
Thu Aug 23 20:01:41 2001 Kristian Rietveld <kristian@planet.nl>
* gtk/gtktreemodelsort.[ch], gtk/gtktreesortable.[ch],
gtk/gtktreestore.[ch], gtk/gtktreeviewcolumn.[ch],
gtk/gtkliststore.[ch]: use GtkSortType instead of GtkTreeSortOrder.
(#59173).
Thu Aug 23 16:26:47 2001 Tim Janik <timj@gtk.org>
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_finalize):
* gtk/gtktextmark.c (gtk_text_mark_finalize): chain parent class
handlers, pointed out by Joshua N Pritikin <vishnu@pobox.com>.
Wed Aug 22 19:15:39 2001 Owen Taylor <otaylor@redhat.com>
[ Patch from Sebastian Wilhelmi, 52790 ]
* gtk/gtkversion.h.in gtk/gtk.h: New file replacing gtkcompat.h
* gdk/gdkcompat.h gdk/gdk*.h gtk/gtkcompat.h.in gtk/gtk*.h:
Move compatibility macros from g[dt]kcompat.h to within
#ifndef G[DT]K_DISABLE_DEPRECATED in each file.
* gdk/gdk-pixbuf-csource.c: Fix up include of gtkcompat.h.
* demos/Makefile.am demos/gtk-demo/Makefile.am
docs/reference/gdk-pixbuf/Makefile.am modules/input/Makefile.am
tests/Makefile.am: Remove references to -G[DT]K_DISABLE_DEPRECATED.
* demos/{pixbuf-demo.c,testpixbuf-drawable.c,testpixbuf-save.c,
testpixbuf.c}: Fix usages of deprecated functions.
Wed Aug 22 18:25:46 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtktreeview.c: Fix selection. I think it's all dandy now.
We check the current event for modifiers rather than try to trap
all presses.
Sun Aug 19 03:22:59 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtkliststore.c: Fix up warnings, #58928.
* gtk/gtktreeselection.h: Change signal prototype, #58647
* gtk/gtktreeview.c (_gdk_tree_view_find_node): Make more robust,
#59221.
* gtk/gtkstyle.c: Actually prelight arrow, #50981
2001-08-18 Hans Breuer <hans@breuer.org>
* gdk/gdk.def : updated externals
* gdk/win32/gdkselection-win32.c : returning TRUE with gdk_selection_set
is required to get (at least) visible in entry fields. Some selections
are really handled now - even on win32 - but copying via middle
mouse button into a different app needs to wait ...
* gdk/win32/gdkdnd-win32.c : implemented inter-app drag&drop
mostly by stealling code from gdkdnd-fb.c. Thanks to who ever wrote it!
* gdk/win32/gdkevents-win32.c : some tweaking to get better expose
handling. I'm not sure if it is better now, but at least not worse
* gdk/win32/gdkgeometry-win32.c : replaced every call to MoveWindow
with SetWindowPos () which allows more fine-tuning backing-store wise
* gdk/win32/gdkwindow-win32.c : allow unraised gdk_window_show ().
Also changed move/resize to be more like the X version.
* gtk/gtk.def : updated externals
2001-08-19 Sven Neumann <sven@gimp.org>
* gtk/gtktooltips.c
* tests/testtreesort.c
* tests/treestoretest.c: inserted some casts to get rid of compiler
warnings.
Sat Aug 18 04:34:31 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtkcellrenderer.c (gtk_cell_renderer_class_init): 2 new
signals; is_expander/is_expanded.
* gtk/gtlcellrendererpixbuf.c: Allow other expanded and closed
pixbufs.
* gtk/gtktreeview.c: set above properties.
Sat Aug 18 23:01:33 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.h: Really remove set_default_style().
* docs/Changes-2.0.txt: added a note about
gtk_widget_push/pop/set_default_style.
2001-08-18 Havoc Pennington <hp@pobox.com>
* gtk/gtkwindow.c (gtk_window_move_resize): constrain position on
hints_changed in addition to the other cases.
(gtk_window_move_resize): include last position from configure
notify in debug spew
2001-08-18 James Henstridge <james@daa.com.au>
* gtk/gtkaccelgroup.c (gtk_accel_group_object_destroy): use the
second argument to the weak ref notify, cleaning up some uglyness.
(gtk_accel_group_attach): remove and add the weak notifier when
changing the accel groups slist.
(gtk_accel_group_detach): same here.
Fri Aug 17 17:30:34 2001 Tim Janik <timj@gtk.org>
* gtk/gtktreemodel.c (gtk_tree_path_new_from_string): const correct
string parameter.
* gtk/gtkoptionmenu.c (gtk_option_menu_set_menu): connect to
GtkMenuShell::selection_done, now that we have it, instead of
::deactivate so we're not tearing the menu apart and notify
the user prematurely.
Thu Aug 16 05:22:01 2001 Tim Janik <timj@gtk.org>
* gtk/gtkwindow.c (gtk_window_move_resize): if we actually move our
window, clear window->need_default_position to avoid infinite loops.
some comment fixups and GTK_RESIZE_IMMEDIATE fixups.
Wed Aug 15 12:36:55 2001 Tim Janik <timj@gtk.org>
* gtk/gtktreeview.c (gtk_tree_view_set_model): move all model setup
code into this place. get rid of GTK_TREE_VIEW_MODEL_SETUP usage.
(gtk_tree_view_set_property): don't cast possible NULL objects.
(gtk_tree_view_destroy): reset the model to NULL.
* gtk/gtktreeselection.c (gtk_tree_selection_finalize): chain
parent_class handler.
2001-08-17 Anders Carlsson <andersca@gnu.org>
* gtk/gtkstyle.c (create_expander_affine): Divide with floating
point numbers so that the result will be floating point.
Sun Aug 12 10:39:12 2001 Owen Taylor <otaylor@redhat.com>
* Makefile.am (EXTRA_DIST): Fix problem with trying to
dist files from intl/, which is no longer there.
Sat Aug 11 14:32:14 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.h (gtk_widget_set_default_visual): Add some
compat macros for push/pop/set_visual that were supposed
to be added a long time ago, but got dropped.
2001-08-07 Havoc Pennington <hp@pobox.com>
* gtk/gtkfilesel.c (open_ref_dir): fix a typo.
* gtk/gtkplug.c (gtk_plug_init): remove setting of auto_shrink;
some fixage is needed here, but nothing simple. Owen understands
it. ;-)
* gtk/gtkwindow.h, gtk/gtkwindow.c: Rework code and API for window
sizing and positioning. Also, fix bug in compute_geometry_hints
(width/height confusion for setting min size).
(gtk_window_move): new function
(gtk_window_resize): new function
(gtk_window_get_size): new function
(gtk_window_get_position): new function
(gtk_window_parse_geometry): new function
* gtk/gtkwidget.c (gtk_widget_set_size_request): new function
(gtk_widget_get_size_request): new function
(gtk_widget_get_usize): delete, that was a short-lived function
;-)
(gtk_widget_set_usize): deprecate
(gtk_widget_set_uposition): deprecate, make it a trivial
gtk_window_move() wrapper
(gtk_widget_class_init): remove x/y/width/height properties,
add width_request height_request
* demos/*: update to avoid deprecated functions
* gtk/gtklayout.c: add x/y child properties
* gtk/gtkfixed.c: add x/y child properties, and get rid of
uses of "gint16"
* tests/testgtk.c (create_window_sizing): lots of tweaks to window
sizing test
* gdk/x11/gdkevents-x11.c (gdk_event_translate): Ensure that
configure events on toplevel windows are always in root window
coordinates, following ICCCM spec that all synthetic events
are in root window coords already, while real events are
in parent window coords. Previously the code assumed that
coords of 0,0 were parent window coords, which was
really broken.
* gtk/gtkcontainer.c (gtk_container_get_focus_chain): fix
warning
* gdk/gdkwindow.h (GdkWindowHints): add GDK_HINT_USER_POS
and GDK_HINT_USER_SIZE so we can set USSize and USPosition
hints in gtk_window_parse_geometry()
* gdk/x11/gdkwindow-x11.c (gdk_window_set_geometry_hints): support
new USER_POS USER_SIZE hints
* gtk/gtkclipboard.c (request_text_received_func): ask apps for
COMPOUND_TEXT instead of TEXT
* gdk/x11/gdkselection-x11.c (gdk_utf8_to_compound_text): correctly
interpret the return value of g_string_to_compound_text()
(#55152)
2001-08-07 James Henstridge <james@daa.com.au>
* gtk/gtkaccellabel.c (gtk_accel_label_set_accel_object): refetch
the accelerator when the accel object is changed. Fixes bug
#58628.
* modules/input/gtkimcontextxim.c (mb_to_utf8), xim_text_to_utf8):
Skip g_convert when to_codeset and from_codeset are both 'UTF-8'
(gnome bugzilla #58202)
2001-08-06 Havoc Pennington <hp@pobox.com>
* gdk/x11/gdkimage-x11.c (_gdk_x11_get_image): The whole
GDK_IS_WINDOW() branch of this was a bit screwed up, because
it was expecting a GdkWindow, not a GdkWindowImplX11.
Also, we were getting the window rect in screen coords
and the screen rect in window coords then intersecting
them; instead, get window rect in window coords.
Finally, there were codepaths that resulted in a stuck server grab
(when the window was fully onscreen, or on gdk_image_new()
failure); make the server ungrab thing a bit more
robust/consistent.
2001-08-06 Sven Neumann <sven@gimp.org>
* gdk/gdkpango.c (gdk_pango_context_destroy):
check if info->colormap != NULL before unref'ing it. It might have
been set to NULL using gdk_pango_context_set_colormap().
Sun Aug 5 11:24:27 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkcolorsel.c (gtk_color_selection_set_current_alpha):
Fix conversion from float to int so that we don't get
skew in the int => float => int roundtrip.
(#58120, reported by Vitaly Tishkov). Also fix problem
where if no alpha was set, the returned alpha
from (say) set_current_alpha() was returned as 1, not 65535.
Sat Aug 4 19:28:21 2001 Owen Taylor <otaylor@redhat.com>
* tests/testgtk.c: Patch from Hans (with various modifications),
to add the ability to use testgtk as a rough-and-ready
benchmark. Try, 'testgtk --bench all:5' (if you want decent
numbers, run without a window manager)
2001-08-04 Alexander Larsson <alexl@redhat.com>
* gdk/win32/gdkinput.c:
Add #ifdef HAVE_WINTAB around wintab.h include.
* gtk/gtk.def:
Removed marshals that have been moved to glib.
Commented out plug and socket. They didn't compile for me
on win32.
2001-08-04 Hans Breuer <hans@breuer.org>
* gtk/stocks-icons/makefile.msc : new file
* gtk/makefile.msc.in : use it
* gtk/gtkstyle.c : not all platforms do provide M_PI and
friends, but luckily there is G_PI
* gtk/gtk.def : updated
* gdk/win32/gdkwindow.c (gdk_window_new) : don't make all TEMP
windows WS_POPUP, but only those without a parent. This fixes the
mis-alignment between the selectable (temp, input only) window and
the window text of GtkLabel.
(gdk_window_show) : respect private->state when actually showing
the window.
(gdk_window_set_transient_for) : Implementation from Wolfgang
Sourdeau <wolfgang@contre.com> ported to 2.0 and added some
error handling. Should fix#50586.
* gdk/win32/gdkevents-win32.c : beautify log output
2001-08-04 Michael Natterer <mitch@gimp.org>
* gtk/gtkitemfactory.c (gtk_item_factory_create_item):
Need to show the image after adding it to the GtkImageMenuItem.
This used to work without in testgtk because of the
gtk_widget_show_all() at the end of the function.
(Closes#54978).
Tue Jul 31 22:59:33 2001 Tim Janik <timj@gtk.org>
* gtk/gtknotebook.c (gtk_notebook_get_child_property):
(gtk_notebook_set_child_property): fix finding of child's page,
since we have to validly deal with labels and menus here as well.
(gtk_notebook_get_child_property): fix warning.
(gtk_notebook_class_init): property tab_pack is of type
GTK_TYPE_PACK_TYPE (enum) not boolean.
(gtk_notebook_find_child): don't always warn, we might be looking
for a label or menu child.
(gtk_notebook_map): fix mapping of panel.
* gtk/gtkwidget.c (gtk_widget_set_child_visible): always constrain
widget's mapped state, regardless of the value being set equals
old settings, since things like REALIZED(parent) or MAPPED(parent)
may have changed since the old value was set. make it an error to
invoke this function on a toplevel widget.
* gdk/gdkprivate.h:
* gdk/x11/gdkx.h:
Put all mentions of GdkFont inside #ifndef GDK_DISABLE_DEPRECATED.
* demos/gtk-demo/menus.c: (do_menus): Cast to G_OBJECT, not
GTK_OBJECT.
