* gdk/x11/{gdkevents-x11.c,gdkmain-x11.c,gdkprivate-x11.h,
gdkwindow-x11.c}: Robustify tracking of pointer grab window.
* gdk/x11/gdkmain-x11.c: Keep track of current keyboard
grab window.
* gdk/x11/gdkmain-x11.c (gdk_pointer_grab_info_libgtk_only,
gdk_keyboard_grab_info_libgtk_only): Private libgtk => libgtk
API for finding out current grab information.
* gtk/gtkmain.c (rewrite_event_for_grabs): Rewrite events
so that the effective behavior of owner_events = TRUE is changed
to "deliver events to same window group normally" instead
of "deliver events to same application normally. #69934
* gtk/gtkrange.c: Use an explicit gtk_grab_add() so that
it works within the GtkList combo, where there is a
owner_events = FALSE gdk_pointer_grab() already in effect.
(#65006, reported by Damon Chaplin)
Wed Feb 27 17:32:09 2002 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_get_props): if CAN_FOCUS
reserve focus_line_width + focus_line_pad extra
space and draw the focus in that space. #72027.
Wed Feb 27 10:34:46 2002 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_set_range): After computing
the clamped value, actually set it. (#62639, Sergey Kuzminov)
Fri Feb 22 20:28:18 2002 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c: Applied patch from Thomas Leonard to make
stepper click to scroll take effect immediately, rather than after
a delay (#67649).
* gtk/gtkrange.c: Remove right-click == step in trough since it
isn't a useful binding and it's a large area to hit accidentally.
(Leave it on the steppers since its more useful there and less
likely to do accidentally.)
2002-02-14 Jody Goldberg <jody@gnome.org>
* gtk/gtkrange.c (gtk_range_class_init) : add new signal
'adjust_bounds' to potentialy change the bounds before assigning the
new value and camping it to the existing bounds.
(gtk_range_internal_set_value) : used here. #68800.
* gtk/gtkmarshalers.list : add VOID:DOUBLE
Sun Dec 09 15:06:51 2001 George Lebl <jirka@5z.com>
* gtk/gtkrange.c (gtk_range_calc_layout): check for 0 value on the
denominator in the horizontal case just like we do in the vertical
case (why I didn't notice that there were two cases the first time
around is beyond me:). Also fix indentation in the vertical case.
Thu Dec 6 16:50:17 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c: Make button 1 clicks on the trough
do pages, button 3 steps. (Patch from Hans Breuer
#63735)
Mon Dec 3 16:39:17 2001 Owen Taylor <otaylor@redhat.com>
Patch from Bill Haneman (with many modifications) to make
the focus color work on dark themes and to make the
focus line width configurable. (#61079, #63074)
* gtk/gtkwidget.c: Add style properties,
::focus-widget, ::focus-line-width, and ::focus-padding.
* gtk/gtkstyle.[ch]: Make gtk_paint_focus() take a
state argument as well so we can use fg[STATE] to
draw instead of always drawing with black.
Cange paint_focus() to respect GtkWidget::focus-width
and GtkWidget::focus-line-pattern. Fix continuity
problem where the default 1-1 stipple had a blob
in one corner and a gap in the other. Change the
interpretation of x/y/width/height to be the bounding
box of the focus rect instead of the rectangle
passed to gdk_draw_rectangle.
* gtk/gtkcheckbutton.c gtk/gtklistitem.c gtk/gtknotebook.c
gtk/gtkoptionmenu.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c
gtk/gtktextview.c gtk/gtktreeview.c: Handle ::focus-width
and ::focus-line-padding.
* gtk/gtkentry.c: Handle :;focus-width property; cleanup
and remove duplicated code; fix drawing of focus rectangle
when interior-focus = FALSE. (#63072, #63073)
* gtk/gtkrange.c gtk/gtktext.c gtk/gtktreeitem.c
gtk/gtktreeviewcolumn.c: Basic fixups to make compile;
Range and TreeViewColumn will need more extensive fixing.
* gtk/gtkcolorsel.c: Honor focus line attributes when
drawing the focus on the color swatches. (#63071)
* gtk/gtkhsv.c: Honor focus line attributes when
drawing the focus for the ring and triangle.
* docs/widget_geometry.txt: Start at documenting how
various widgets are drawn.
* gtk/gtkbutton.c (_gtk_button_paint): Export
_gtk_button_paint() librarywide, so we don't have
duplicate a bunch of code in gtktogglebutton.c.
* gtk/gtktogglebutton.c: Use _gtk_button_paint().
2001-11-28 Havoc Pennington <hp@redhat.com>
* gtk/gtktextview.c (gtk_text_view_paint): put the warning
explaining the validation error in front of the G_BREAKPOINT
* gtk/gtkrange.c (gtk_range_adjustment_value_changed): call
process updates with include_children = FALSE instead of TRUE, so
we redraw the range only, not the whole darn window. Making
GtkRange a NO_WINDOW widget had weirdly caused the text widget
Trace/breakpoint trap bug to become much easier to trigger.
Fri Nov 23 18:36:42 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_button_press): Offset
invalidated range correctly.
* gtk/gtkclist.c (hadjustment_value_changed): Fix scrolling
of title window. (#65001, reported by Damon Chaplin)
* gtk/gtkcombo.c (gtk_combo_button_event_after): Replace
horrible hack with use of ::event_after.
Sat Nov 17 18:26:45 2001 Owen Taylor <otaylor@redhat.com>
* gtk/Makefile.am gtk/gtkmarshal.list gtk/gtkmarshalers.list
gtk/*.c gtk/gtksignal.h: Make gtkmarshal.list/gtkmarshal.h
only for compatibility with GTK+-1.2; and deprecate it;
put all marshalers we actually use into gtkmarshalers.list
and use the _gtk_marshal_ prefix for these marshalers.
Thu Nov 15 14:19:34 2001 Owen Taylor <otaylor@redhat.com>
* gdk/gdkwindow.c (gdk_window_invalidate_maybe_recurse): Cal
gdk_window_invalidate_maybe_recurse() for recursion.
(Soeren Sandmann)
* gtk/gtkviewport.c: Make !redraw_on_allocate. (Soeren Sandmann)
* gtk/gtkcontainer.c (gtk_container_expose): Call
gtk_container_forall() not _foreach() to propagate,
since we need to propagate exposes to internal children
as well.
* gtk/gtkwidget.c (gtk_widget_set_events, gtk_widget_add_events):
Remove the restriction of only being able to call these
on window widgets, since we have lots of NO_WINDOW widgets
with windows now; for add events, recurse over the children
of widget->window to find one owned by the widget.
* gtk/gtkbutton.[ch]: Make a NO_WINDOW widget, using an input-only
window to catch events.
* gtk/gtktogglebutton.[ch]: Remove the code for switching
between NO_WINDOW and WINDOW widgets based on the mode.
* gtk/gtkcheckbutton.c gtk/gtkoptionmenu.c gtk/gtkclist.c
gtk/gtktreeview.c: Adopt to NO_WINDOW change for GtkButton.
* gtk/gtkrange.[ch]: Make into a NO_WINDOW widget.
* gtk/gtkhscale.c, gtk/gtkvscale.c: Adopt to NO_WINDOW
change for range.
* gtk/gtknotebook.[ch]: Make into a NO_WINDOW widget.
* docs/Changes-2.0.txt: Add a note about the NO_WINDOW changes.
Thu Nov 1 20:09:31 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c: Patch from George Lebl to
fix division by zero for full scroll bars. (#62114)
Wed Jul 18 19:28:46 2001 Owen Taylor <otaylor@redhat.com>
* gtk/*.c: Patch from Matthias Clasen to remove remove
all instances of g_return_if_fail (foo != NULL); that are
immediately before a g_return_if_fail (GTK_IS_FOO (foo));
since the second check catches the NULL anyways.
Sat Jul 14 12:47:35 2001 Tim Janik <timj@gtk.org>
* gtk/gtkrange.c:
(second_timeout):
(initial_timeout):
(update_timeout): add GDK_THREADS_ENTER/GDK_THREADS_LEAVE.
(gtk_range_calc_layout): compute the new layout based on an
adjustment->value being passed in as argument.
(gtk_range_button_press): for button2 slider warps, first recalc
the layout, then adjust the value. also, use update_slider_position()
for adjusting the value, so we keep pixel quantisation at which we
usually operate (upon motion or button releases). the reason for this
is that, we can't change the adjustment upon button2 presses to a non
quantised value and upon button2 release re-quantise the value since
that'd alter the value even if we didn't get any motion events (causing
unexpected scroll area warps upon release and/or slider pixel-jitter).
(gtk_range_motion_notify): update the slider position from queried
coordinates, not event coordinates.
Fri Jul 13 09:47:52 2001 Tim Janik <timj@gtk.org>
* gtk/gtkstyle.c (gtk_default_draw_focus): fix line style resetting,
the default gc values are: width=0, CapBut, JoinMiter.
Sun Jun 24 11:29:35 2001 Owen Taylor <otaylor@redhat.com>
* gdk/x11/gdkimage-x11.c (gdk_image_new): Fix stupid error
introduced last night that was making things decidedly not work.
* gtk/*.[ch]: Patch from Kristian Rietveld adding 80 getters
so that we have getter/setter pairing everywhere it makes
sense. (#55767)
* gtk/gtkradiobutton.[ch] gtk/gtktoolbar.c tests/testgtk.:
Rename gtk_radio_button_group to gtk_radio_button_get_group, add a
deprecated compat macro. (#55516)
* gtk/gtklabel.[ch]: Add functions
gtk_label_set/get_use_underline(), gtk_label_set/get_use_markup(),
gtk_label_set_label(), which mirror the property API for GtkLabel.
Make gtk_label_get_attributes() only reflect the attributes
set by gtk_label_set_attributes.
* gtk/gtknotebook.c (gtk_notebook_set_current_page) gtk/gtkcompat.h: Rename
from gtk_notebook_set_page().
Wed Jun 20 04:28:24 2001 Tim Janik <timj@gtk.org>
* gtk/gtkrange.c (gtk_range_class_init): hum, "adjustment" was a
construct property in 1.2 and still needs to be.
* gtk/gtkwidget.c: "composite_child" is not a settable property.
2001-06-06 Havoc Pennington <hp@redhat.com>
* gtk/gtkrange.c (gtk_range_class_init): add "inverted" property
* gtk/gtkscale.c (gtk_scale_class_init): Change Page Up and Page
Down to move visually rather than logically, since it confuses
people. Add -/+ and Ctrl--/+ bindings for logical movement.
2001-06-05 Havoc Pennington <hp@redhat.com>
* gtk/gtkspinbutton.c (gtk_spin_button_set_range): clamp the value
to the range that was set
* gtk/gtkrange.c: add value_changed signal, primarily
intended for use with GtkScale
(gtk_range_set_increments): new function
(gtk_range_set_range): new function with weird name
(gtk_range_set_value): new function
(gtk_range_get_value): new function
* gtk/gtkspinbutton.c (gtk_spin_button_get_value): rename
from gtk_spin_button_get_value_as_float(). Compat #define
added for get_value_as_float.
* gtk/gtkhscale.c (gtk_hscale_new_with_range): new function
* gtk/gtkvscale.c (gtk_vscale_new_with_range): new function
2001-06-05 Havoc Pennington <hp@redhat.com>
* test-loaders.c (main): use putenv not setenv, reported by
Armin Theissen
2001-06-04 Havoc Pennington <hp@redhat.com>
* gtk/gtkrange.c (gtk_range_adjustment_value_changed):
Process updates immediately, to prevent funny lag effect
when scrolling, at some mild potential efficiency cost.
2001-06-03 Havoc Pennington <hp@pobox.com>
* gtk/gtkstyle.c (gtk_default_draw_slider): make this special-case
hscale/vscale details, so we can use it for scrollbar as well.
* tests/testgtk.c (reformat_value): honor digits from GtkScale
* gtk/gtkenums.h (GtkTroughType): Remove this enum
(GtkScrollType): add START and END from GtkTroughType
* gtk/gtkstyle.c (gtk_default_draw_slider): was not properly using
its x/y arguments
* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkscrollbar.h,
gtk/gtkscrollbar.c, gtk/gtkscale.h, gtk/gtkscale.c,
gtk/gtkhscrollbar.h, gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.h,
gtk/gtkvscrollbar.c, gtk/gtkhscale.h, gtk/gtkhscale.c,
gtk/gtkvscale.h, gtk/gtkvscale.c: Rewrite GtkRange and subclasses.
Notable changes in the process:
- stepper_size style property is the height for vertical
ranges, width for horizontal; the other dimension matches
the trough size
- add ability to do NeXT-style steppers (and several other styles
that don't make any sense)
- added min_slider_length, fixed_slider_length properties to
GtkScrollbar
- cleaned some private (or at least useless) functions out of
gtkscale.h
- moved bindings to GtkScale from subclasses, even arrow keys,
since blind users don't know scale orientation.
- change move_slider action signal to use new GtkScrollType,
remove GtkTroughType argument
- digits rounds the values a range will input to the given
number of decimals, but will not try to force adjustment
values set by other controllers. That is, we no longer
modify adjustment->value inside a value_changed handler.
- added getters for GtkScale setters
- middle-click begins a slider drag
2001-05-17 Alexander Larsson <alla@lysator.liu.se>

Convert from GtkArg to GParam, based on patch by John Margaglione.
* gtk/gtkhscale.c:
* gtk/gtkvscale.c:

* gtk/gtkvscrollbar.c:
* gtk/gtkrange.c:
Move adjustment property to GtkRange.
* gtk/gtklabel.c:
Setup mnemonics on property changes
* gtk/gtkwidget.c (gtk_widget_get_property):
GdkExtensionMode is an enum, not a flag. Set it with
g_value_set_enum ().
* tests/prop-editor.c:
Better propery editor.
* tests/testgtk.c:
Add new property test. Pass zero to the property editor to
get properties from all derived types.
Mon Apr 30 20:29:27 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkbutton.c gtk/gtkcheckbutton.c gtk/gtkoptionmenu.c
gtk/gtkspinbutton.c gtk/gtkstyle.c gtk/gtkwidget.c:
New default theme! A slighly improved version of the 2.0 Raleigh
theme, with Windows-esque focus/drawing default.
(GtkWidget::interior_focus defaults to TRUE.)

* gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line):
(gtk_text_layout_move_iter_to_next_line): fix these two for
invisible text, lots of other stuff still hosed.
* gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook):
new function, replaces the get/set palette stuff. This function
is intended for use by libgnomeui which should set the hook to a
thing which sets the palette in GConf, and we need the
GConf-to-xsettings proxy which will result in the change being
propagated back to the GTK app.
* gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning
about unusable signals that it may be because the signal has
parameters.
* gtk/gtkwidget.c (gtk_widget_modify_style): always copy the
style, otherwise gtkrc.c won't know to create a new GtkStyle for
it.
(gtk_widget_modify_color_component): call
gtk_widget_modify_style() so the rc style will get copied.
(gtk_widget_modify_font): ditto
* gtk/gtkrc.c: make a couple variables static
* gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide
help button by default, since it does nothing
* gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool
around with UI
* gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify
so we can have tooltips
* gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we
can have tooltips
* gdk/gdkimage.h: mark gdk_image_new_bitmap with
GDK_ENABLE_BROKEN, because its memory behavior is completely
hosed.
* gtk/gtknotebook.c: remove key press handler, replace with
binding set, add numeric keypad support
* gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete
* gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms

GDK_KP_Enter in addition to GDK_Return
* gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to
activate on entry instead of key press
(gtk_font_selection_on_clist_key_press): get
rid of this signal handler, not needed with new font sel.
* gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a
no-longer-needed emit_stop_by_name(), just return TRUE
* gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings
cruft, this widget is no longer focusable.
* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c,
gtk/gtkhscale.c: Get rid of trough_keys virtual function, add
move_slider action signal, add binding set for vscale/hscale, in
the process support numeric keypad
* gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings;
make GDK_Return and GDK_KP_Enter activate the entry via
binding set, instead of hardcoded.
Tue Mar 27 22:36:07 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.h gtk/gtkrange.h: Apply patch from
Nils Barth fixing event return values. (#51041)

functions.
* gtk/gtk[vh]scrollbar.c gtk/gtk[vh]range.c: Fix
return values for trough_keys functions.
* gtk/gtkwidget.h (struct _GtkWidgetClass): Fix return
value for add_accelerator (shoudl have been a void
return.)
* gtk/gtkcellrenderer.[ch]: gtkcellrenderertoggle.h:
Fix return type of EVENT.

signal return a boolean.
Mon Mar 19 15:53:36 2001 Owen Taylor <otaylor@redhat.com>

Change float to double everywhere with the exception of 0<->1.0 alignment
and GtkCurve.
Wed Feb 28 19:10:43 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkclist.c (real_remove_row): Patch from ChiDeok
Hwang to move call to sync_selection() up a few lines
to before the row list is modified, to fix crash when
removing rows in the undo_selection list.
(Test case provided by Daniel Elstner:
http://mail.gnome.org/archives/gtk-list/2001-February/msg00359.html)
Fri Feb 23 15:06:48 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtktree.c (gtk_tree_class_init): Do the setting
of tree->root_tree in parent_set rather than _map(),
fixing #50892 in a bit better manner.
Thu Feb 22 17:07:58 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenu.c (gtk_menu_popup): Don't flip cursor. (#50934)

warning, make warnings more verbose, treat a error
in shmat as permanent, and don't try again.
(#51163, Ed Randall.)
Mon Feb 19 20:15:28 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_timer_1st_time): Add an initial
delay for the first click before starting to scroll.
(based on #51026, gtk-enf-990512-0.patch, Eric Fisher)
* gtk/gtktext.c: GtkText should have I-beam cursor.
(based on gtk-enf-990513-1.patch, Eric Fisher.)

mask. (#51039, fix from Martin Maierhofer)
Fri Feb 16 20:09:42 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkctree.c (gtk_ctree_class_init): Add bindings
for unshifted + and shifted = for non-us keyboards.
Make <Control>+ and <Control>- work as well as
<Control>KP_Plus, <Control>KP_Minus for recursive
open/close. (#2682, Ren Seindal)
Fri Feb 16 18:50:59 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenushell.c (gtk_real_menu_shell_cancel): Unset
the active menu item before deactivating the menu,
so gtk_menu_popdown doesn't change the history. (#50964)
Fri Feb 16 15:55:22 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtktreeitem.c (gtk_tree_item_draw_lines):
draw lines with text_gc rather than black_gc.
(Patch from Vlad Harchev <hvv hippo ru>, #50926)
2001-02-28 Havoc Pennington <hp@redhat.com>
* gtk/gtkwidget.h (struct _GtkWidgetClass): Remove draw_focus and
draw_default
(gtk_widget_draw_focus): remove this function; we could instead
make it just gtk_widget_draw(), but in most cases I think the
result would be broken user code, so think it's better to have
that code not compile and get fixed
(gtk_widget_draw_default): ditto
* gtk/gtkwidget.c: Add default handlers for focus_in_event and
focus_out_event that set/unset GTK_HAS_FOCUS and call queue_draw
* gtk/gtkwindow.c (gtk_window_set_default): just queue a draw when
widgets lose/get the default, instead of calling draw_default
* docs/Changes-2.0.txt: note about all this
Then fixed every widget in GTK, I won't list all the filenames.
2001-02-19 Havoc Pennington <hp@redhat.com>
* gtk/gtktreemodel.c (gtk_tree_model_get_valist): hmm, someone
changed GLib without fixing GTK
* gtk/gtkrange.h: Rename all the stupid implementation detail
functions to have an underscore in front. Most of them should
probably just go away, but for starters don't export them.
Bug #50482
2001-02-19 Havoc Pennington <hp@redhat.com>
* gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
2001-02-16 Havoc Pennington <hp@redhat.com>
* gtk/gtkvscrollbar.c (gtk_vscrollbar_trough_keys): use the visual
scroll steps.
* gtk/gtkvscale.c (gtk_vscale_trough_keys): use the visual scroll
steps, and add Ctrl-arrow shortcuts for paging visually as with
HScale, since Page Up and Page Down move logically.
* gtk/gtkenums.h (GtkScrollType): add GTK_SCROLL_STEP_UP,
GTK_SCROLL_STEP_DOWN, etc. for visual scroll directions
* gtk/gtkrange.c (gtk_range_key_press): handle the visual scroll
steps
(gtk_range_scroll): handle the visual steps
* gtk/gtklist.c (gtk_list_scroll_horizontal): handle the up/down
scroll steps
* gtk/gtkhscale.c (gtk_hscale_trough_keys): use the visual scroll
steps, not the logical ones.
* gtk/gtkclist.c (move_focus_row): handle the up/down scroll steps
(scroll_vertical): handle up/down steps
2001-02-15 Havoc Pennington <hp@redhat.com>
* gdk/gdkpango.c (gdk_pango_layout_line_get_clip_region): convert
the X coordinates so they're with respect to the line, rather than
with respect to the layout.
* gtk/gtkalignment.c: Convert to new property API, patch from Lee
Mallabone
* gtk/testgtk.c (create_range_controls): add vscale tests,
and inverted test

rename gtk_text_buffer_get_end_iter
* gtk/testgtk.c (create_labels): Add test for selectable
* gtk/gtkentry.c (gtk_entry_draw_text): Use new GDK API to draw
the selection stuff. This code is kind of broken since it doesn't
use the theme engine.
* gdk/gdkpango.c (gdk_pango_layout_line_get_clip_region):
fix infinite loop and y offset problem
(gdk_draw_layout_line_with_colors): fix foreground color handling
* gtk/gtklabel.h, gtk/gtklabel.c: Implement a "selectable" flag
that makes the label selectable.
* gtk/gtklabel.c (gtk_label_style_set): recreate the label's
layout when the style is set, since fonts etc. could have changed.
Fri Feb 2 12:26:50 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrc.c (gtk_rc_add_initial_default_files): Get rid of
a bunch of g_strdup_printf("%s%s") in favor of g_strconcat().
* gtk/gtkrc.c Makefile.am: Use $(libdir), not $(exe_prefix),
since some people set $(libdir) separately. (#1290, David Kaelbling)
Thu Feb 1 18:25:46 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkfilesel.c: If PATH_MAX and MAXPATHLEN are not
defined, define MAXPATHLEN to 2048. (The Hurd doesn't have
MAXPATHLEN, but the code here depends on a fixed value.)
(#4524)
Wed Jan 31 22:01:04 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkhandlebox.c (gtk_handle_box_button_changed): Handle the case
where child == NULL and handle_position == RIGHT or BOTTOM. (#8041g)
Wed Jan 31 21:20:39 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkctree.c (real_tree_move): If the node being moved isn't
viewable there is no way that moving the node will cause the
focus row to become not viewable, so omit check on the visibility
of new_sibling, which is irrelevant. (Fixes#8002, David Helder)
Wed Jan 31 20:38:17 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkentry.c (gtk_entry_commit_cb): Delete the current
selection before inserting new text.
Wed Jan 31 18:49:33 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkoptionmenu.c (gtk_option_menu_item_state_changed_cb):
Make the sensitivity of the reparented child track that of
the original parent menu item. (#34218, David Hodson)
* gtk/gtkoptionmenu.c (gtk_option_menu_item_destroy_cb): Handle
the case where the current item is destroyed properly.
* gtk/gtkoptionmenu.c: Some additional code cleanups and fix
some edge cases with child-less menuitems.
Wed Jan 31 17:16:13 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkcombo.c (gtk_combo_window_key_press): Make Return
key pop down window. (#12074, Jon K Hellan)
Wed Jan 31 16:21:42 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtklist.c (gtk_list_signal_item_toggle): Don't allow
toggling of rows off in BROWSE or EXTENDED mode. (#12072, Jon K Hellan)
The solution here isn't perfect - you get an extraneous
emission of "toggle", which could conceivably confuse an app,
but better than the current situation. LXR search seems to
indicate that no apps in GNOME CVS connect to "toggle".
Wed Jan 31 15:46:13 2001 Owen Taylor <otaylor@redhat.com>
* gtk/Makefile.am (libgtkinclude_HEADERS): Move gtkcompat.h from
gtk_public_h_sources to directly here to avoid warning when
building srcdir != builddir. (#9656)
Tue Jan 30 19:49:02 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c: Patch from Kipp Hickman to make the event
handlers in gtkrange.c return the proper values (TRUE == handled)
(#10316).
This is just the tip of the iceberg, but gtkrange.c is the
most common place where the propagation is problematical,
and also a place where it is almost certainly safe to change
this in the stable branch.
(You don't want right click popups on a range control or anything...)
Tue Jan 30 18:57:59 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtktext.c (clear_focus_area): We need to clear the focus
area on focus out, even if a background pixmap isn't set.
(#13941)
Tue Jan 30 18:24:10 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtknotebook.c (gtk_notebook_set_shape): Fix from Sean Cunningham
to deal with setting the shape properly when scrolling arrows are
turned on, but not visible because there is sufficient space.
(#13432)
Tue Jan 30 16:39:25 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkitemfactory.c (gtk_item_factory_delete_item): For menu
items with submenus, destroy the item along with the submenu.
(#7841, Brian Masney(?)) Also, handle paths of the form '<foo>/abcd...'
properly.
* gtk/testgtk.c (menu_items): Add a dummy branch that we delete
later.
Tue Jan 30 15:51:25 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwindow.c (gtk_window_real_set_focus): Fix a problem where
the focus widget sometimes wasn't drawn with the default if there
was no default widget.
* gtk/gtkstyle.c (gtk_style_real_unrealize): free colors,
unreference pixmaps.
* gtk/gtkstyle.c (gtk_style_realize): Reference colormap
for some extra safety.
Mon Jan 29 19:00:01 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtk{ctree.c,clist.c} (set_cell_contents): Handle setting
the text of a cell to the old pointer value better, by
copying the new text before freeing the old text. Some code
cleanup. (#8079, Karl Nelson)
Mon Jan 29 16:50:19 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtklabel.[ch] gtk/gtkframe.[ch]: Make gtk_label_get_text()
gtk_frame_get_label() non strdup'ing, and G_CONST_RETURN.
Mon Jan 29 15:22:51 2001 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmenu.c (gtk_menu_remove): When removing an
item from a menu, check to see if it matches
menu->old_active_menu_item, and if so, unref and clear
old_active_menu_item (Patch from Pavel Cisler)
* gtk/gtkmenushell.c (gtk_menu_shell_remove): Unset
menu_shell->active_menu_item, if it is the child being
removed. (Patch based on that of Gene Ragan, #50337)
Sun Nov 12 13:33:01 2000 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c: Add some missing casts. Support
2 and 3 button clicks on the arrows to mean
"move by pages" and "jump to end". (Like gtkspinbutton)
2000-10-22 Robert Brady <robert@suse.co.uk>
* configure.in: Check for bind_textdomain_codeset
* gtk/gtkmain.c (gtk_init_check): If bind_textdomain_codeset
present, make use of it.
Add a translatable string "default:LTR" which, if translated
to "default:RTL", will cause the default direction to be
Right-to-Left.
* gtk/gtkrange.h, gtk/gtkrange.c: Take into account the widget
direction if marked as flippable.
* gtk/gtkhscale.c: Mark widget as flippable.
Wed Jul 26 12:59:31 2000 Tim Janik <timj@gtk.org>
* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
Fri Jul 14 16:21:26 2000 Owen Taylor <otaylor@redhat.com>
* gtk/gtktextlayout.c: use FALSE for size_only most
of the time when calling gtk_text_layout_get_line_display()
to avoid causing double reshapes when a redraw follows
immediately after.
Tue Jul 11 11:13:40 2000 Owen Taylor <otaylor@redhat.com>
* gtk/gtkrange.c (gtk_range_default_[hv]slider_update): Invalidate
appropriate region and gdk_window_process_updates() so trough
updating doesn't lag behind the window being scrolled.
* gdk/gdkgc.c: Make parent_class pointer static.
Sun Jul 9 21:31:23 2000 Owen Taylor <otaylor@redhat.com>
* gdk/gdk-pixbuf.c gtk/gdk-pixbuf-loader.c gtk/gtktextview.c:
include <string.h>.
* gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable): Fix
cut-and-paste error in computing memory offset for 4 channels.
2000-06-20 Havoc Pennington <hp@redhat.com>
* modules/linux-fb/Makefile.am: Make this compile
without framebuffer enabled
* gdk/linux-fb/Makefile.am: Add conditional to not build
framebuffer unless specified in configure
* gdk/gdkdraw.c (gdk_draw_drawable): Fix bug where I was getting
the size of the target instead of source if -1 was passed for
width/height
* gdk/x11/gdkgeometry-x11.c (gdk_window_compute_position): Fix
width/height confusion.
2000-06-19 Havoc Pennington <hp@redhat.com>
* gdk/x11/gdkx.h (GDK_WINDOW_XWINDOW): change this to be
GDK_DRAWABLE_XID. In the future, we probably want to make it
faster with G_DISABLE_CHECKS turned on.
2000-06-14 Havoc Pennington <hp@redhat.com>
* gdk/Makefile.am: add gdkpixmap.c
* gdk/gdk.c: s/gdk_window_init/_gdk_windowing_window_init/
s/gdk_image_init/_gdk_windowing_image_init
* gdk/gdkcolor.c: make ref/unref compat wrappers for GObject
ref/unref
* gdk/gdkcolor.h: make GdkColormap a GObject subclass
* gdk/gdkcompat.h: remove GdkWindowType compat, since
GdkWindowType is now non-deprecated;
change gdk_window_get_type() compat to be
gdk_window_get_window_type().
* gdk/gdkdnd.h: make GdkDragContext a GObject.
* gdk/gdkdraw.c, gdk/gdkdraw.h: Convert GdkDrawable to a pure
virtual GObject. Make all functions call into the vtable.
Move gdk_image_put() guts in here. Remove GdkDrawableType
and gdk_drawable_get_type(), these are now GdkWindow-specific.
draw_image, get_depth, get_size, set_colormap, get_colormap,
get_visual added to the vtable.
* gdk/gdkgc.h, gdk/gdkgc.c: Convert GdkGC to a pure virtual
GObject. Virtualize everything.
(gdk_gc_new_with_values): remove check for destroyed window,
because now GdkWindow::create_gc will check this.
(gdk_gc_set_values): New function to set GC values, this
was already implemented but wasn't in the header
* gdk/gdkimage.h, gdk/gdkimage.c: Convert GdkImage to a GObject.
* gdk/gdkinternals.h: Remove _gdk_window_alloc(), remove
_gdk_window_draw_image(), remove _gdk_windowing_window_class,
remove _gdk_window_class; add _gdk_window_impl_get_type() and
_gdk_pixmap_impl_get_type(). Rename gdk_window_init to
_gdk_windowing_window_init, rename gdk_image_init to
_gdk_windowing_image_init.
* gdk/gdkpango.c: Reflect GObject-ification of PangoContext.
(gdk_draw_layout): Remove check for destroyed window,
because all the drawable methods already check it.
* gdk/gdkpixmap.h, gdk/gdkpixmap.c: Convert GdkPixmap to GObject.
Add gdkpixmap.c which contains implementation of GdkDrawable
virtual table (by chaining to a platform-specific implementation
object).
* gdk/gdkprivate.h: Remove GDK_IS_WINDOW, GDK_IS_PIXMAP,
GDK_DRAWABLE_DESTROYED. Add GDK_WINDOW_DESTROYED. Replace
GDK_DRAWABLE_TYPE with GDK_WINDOW_TYPE. Remove GdkDrawablePrivate,
GdkWindowPrivate, GdkImageClass, GdkImagePrivate, GdkGCPrivate,
GdkColormapPrivate.
* gdk/gdktypes.h: #include <glib-object.h>
* gdk/gdkwindow.h, gdk/gdkwindow.c: Convert GdkWindow to GObject.
Move most functionality to platform-specific implementation
object. GdkWindow itself now handles the backing store, then
chains to the platform-specific implementation.
(gdk_window_get_window_type): return GdkWindowType of the window.
(gdk_window_peek_children): New routine, returns the children of
a GdkWindow
(gdk_window_get_children): Was in X11-specific code and did
XQueryTree. Changed to simply return a copy of window->children;
so it can go in cross-platform code.
* gdk/x11/Makefile.am: fix broken MKINSTALLDIRS path
* gdk/x11/gdkcolor-x11.c: implement X-specific parts of
GdkColormap; just changed to use the new private data instead
of casting to GdkColormapPrivate.
* gdk/x11/gdkcursor-x11.c: added a couple typechecks to
gdk_cursor_new().
* gdk/x11/gdkdnd-x11.c: Change the way we access private fields
(private data member in the GObject).
(xdnd_manager_source_filter): Function had broken
error handling, fix it (use gdk_error_trap_push).
* gdk/x11/gdkdrawable-x11.c: This file now implements
a base class for GdkWindowImplX11/GdkPixmapImplX11. This
base class is purely for the convenience of the X port,
and not part of the interface to cross-platform GDK.
* gdk/x11/gdkevents-x11.c: Reflect various renamings.
* gdk/x11/gdkgc-x11.c: Implement a subclass of GdkGC that's
specific to X, and returned by the create_gc virtual method
of GdkDrawableImplX11.
(gdk_x11_gc_set_dashes): Change this to take an array of gint8
rather than gchar, this was also changed in the GdkGC vtable.
(gdk_x11_gc_values_to_xvalues): If GdkGCValues is NULL, or the
mask is 0, return immediately, instead of checking every flag.
This is faster, and keeps us from segfaulting if values is NULL
and the mask contains some nonzero flags.
* gdk/x11/gdkgeometry-x11.c: deal with all the rearranging of
GdkWindow.
* gdk/x11/gdkglobals-x11.c: change type of grab window, since
GdkWindowPrivate is gone.
* gdk/x11/gdkim-x11.c: rename things that got renamed.
* gdk/x11/gdkimage-x11.c: implement in terms of GObject, and
remove the image_put stuff that got transferred to GdkDrawable.
* gdk/x11/gdkinput.c: renamings
* gdk/x11/gdkmain-x11.c: #include <pango/pangox.h>
* gdk/x11/gdkpixmap-x11.c: GObject conversion
* gdk/x11/gdkprivate-x11.h: indentation fixes
* gdk/x11/gdkproperty-x11.c: renamings
* gdk/x11/gdkselection-x11.c: renamings
* gdk/x11/gdkwindow-x11.c: Restructuring and renaming; this now
implements the platform-specific "impl" object.
Moved gdk_window_get_children to gdk/gdkwindow.c
* gdk/x11/gdkx.h: Remove all the private structs and private datas
that no longer exist. Add declaration of GdkGCX11 object here.
Fix all the macros to still work.
* gtk/gtk-boxed.defs: Remove GtkStyle, GdkColormap, GdkWindow,
GdkDragContext from the boxed types since they are now GObjects.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Converted GtkStyle to a GObject,
moved xthickness/ythickness into the instance. GtkStyleClass
functions are now in the standard vtable for GtkStyle, so you have
to create a GObject subclass to write a theme engine.
(gtk_style_copy): fixed a leaked PangoFontDescription
(gtk_style_init): renamed gtk_style_realize, so gtk_style_init
can be the standard GObject function.
* Throughout GTK:
s/style->klass->[xy]thickness/style->[xy]thickness
s/pango_layout_unref/g_object_unref/
* gtk/gtkrc.h, gtk/gtkrc.c: Converted GtkRcStyle to a GObject.
* gtk/gtksocket.c: Use gdk_window_get_user_data() instead of
accessing GDK internals.
* gtk/gtkwidget.c: Use gdk_window_peek_children() instead of
accessing GDK internals.
(follow-on from previous commit)
2000-06-18 Elliot Lee <sopwith@redhat.com>
* gtk/gtkwindow.c: Don't allow creation of a window bigger than the screen.
* gtk/gtkrange.c: Fix the mega-jumpy-with-lagged-events scrollbar
problem by calculating event position relative to the trough
rather than the slider.
* gtk/gtkdnd.c, gtk/gtkcolorsel.c: Include FB headers if appropriate.
* gdk/gdkgc.h: Add GDK_NOR.
* configure.in, Makefile.am: Add modules top level dir
* configure.in: Only use pangox library if building x11 target.
* gdk/gdkdnd.h: Add GDK_DRAG_PROTO_LOCAL enum for future intra-app use.
Fri May 12 17:13:32 2000 Tim Janik <timj@gtk.org>
* docs/Changes-1.4.txt: documented necessary changes for 1.4 transition.
* gtk/gtktext.c: made the adjustments no-construct args, simply
provide default adjustments.
(gtk_text_destroy): release adjustments.
* gtk/gtkprogressbar.c (gtk_progress_bar_class_init): made the
adjustment argument non-construct.
* gtk/gtkprogress.c (gtk_progress_destroy): release adjustment here,
instead of in finalize.
(gtk_progress_get_text_from_value):
(gtk_progress_get_current_text):
(gtk_progress_set_value):
(gtk_progress_get_percentage_from_value):
(gtk_progress_get_current_percentage):
(gtk_progress_set_percentage):
(gtk_progress_configure): ensure an adjustment is present.
Thu May 11 01:24:08 2000 Tim Janik <timj@gtk.org>
* gtk/gtkcolorsel.[hc]:
* gtk/gtkcolorseldialog.[hc]:
* gtk/gtkhsv.[hc]: major code cleanups, destroy handlers need to chain
their parent implementation, use bit fields for boolean values, don't
create unused widgets, usage of glib types, braces go on their own
lines, function argument alignment, #include directives etc. etc. etc..
* gtk/Makefile.am (gtk_public_h_sources): install gtkhsv.h.
Wed May 10 23:29:52 2000 Tim Janik <timj@gtk.org>
* gtk/gtktoolbar.c (gtk_toolbar_destroy): don't unref a NULL tooltips.
* gtk/gtkfilesel.c (gtk_file_selection_destroy): don't free a cmpl_state
of NULL.
* gtk/gtkcombo.c (gtk_combo_item_destroy): don#t keep references
to freed data.
(gtk_combo_destroy): don't keep a pointer to a destroyed window.
* gtk/gtkmenu.c (gtk_menu_init): reset the menu's toplevel pointer
to NULL when the toplevel is getting destroyed.
(gtk_menu_set_tearoff_state): same here for the tearoff_window.
(gtk_menu_destroy):
(gtk_menu_init): store the information of whether we have to
readd the initial child ref_count during destruction in a new
GtkMenu field needs_destruction_ref_count.
* gtk/gtkviewport.c: SHAME! ok this one is tricky, so i note it
here, those reading: learn from my mistake! ;)
in order for set_?adjustment to support a default adjustemnt if
invoked with an adjustment pointer of NULL, the code read (pseudo):
if (v->adjustment) unref (v->adjustment);
if (!adjustment) adjustment = adjustment_new ();
if (v->adjustment != adjustment) v->adjustment = ref (adjustment);
now imagine the first unref to actually free the old adjustment and
adjustment_new() creating a new adjustment from the very same memory
portion. here, the latter comparision will unintendedly fail, and
all hell breaks loose.
(gtk_viewport_set_hadjustment):
(gtk_viewport_set_vadjustment): reset viewport->?adjustment to NULL
after unreferencing it.
* gtk/gtkcontainer.[hc]: removed toplevel registration
functions: gtk_container_register_toplevel(),
gtk_container_unregister_toplevel() and
gtk_container_get_toplevels() which had wrong semantics
anyways: it didn't reference and copy the list.
* gtk/gtkwindow.c: we take over the container toplevel registration
bussiness now. windows are registered across multiple destructions,
untill they are finalized. the initial implicit reference count
users are holding on windows is removed with the first destruction
though.
(gtk_window_init): ref & sink and set has_user_ref_count, got
rid of gtk_container_register_toplevel() call. add window to
toplevel_list.
(gtk_window_destroy): unref the window if has_user_ref_count
is still set, got rid of call to
gtk_container_unregister_toplevel().
(gtk_window_finalize): remove window from toplevel list.
(gtk_window_list_toplevels): new function to return a newly
created list with referenced toplevels.
(gtk_window_read_rcfiles): use gtk_window_list_toplevels().
* gtk/gtkhscale.c (gtk_hscale_class_init): made the GtkRange
adjustment a non-construct arg.
* gtk/gtkvscale.c (gtk_vscale_class_init): likewise.
* gtk/gtkhscrollbar.c (gtk_vscrollbar_class_init): likewise.
* gtk/gtkvscrollbar.c (gtk_vscrollbar_class_init): likewise.
* gtk/gtkrange.c: added some realized checks.
(gtk_range_destroy): get rid of the h/v adjustments in the
destroy handler instead of finalize. remove timer.
(gtk_range_get_adjustment): demand create adjustment.
* gtk/gtkviewport.c: made h/v adjustment non-construct args.
we simply create them on demand now and get rid of them in
the destroy handler.
(gtk_viewport_destroy): get rid of the h/v adjustments in the
destroy handler instead of finalize.
(gtk_viewport_get_hadjustment):
(gtk_viewport_get_vadjustment):
(gtk_viewport_size_allocate): demand create h/v adjustment
if required.
* gtk/gtkwidget.c (gtk_widget_finalize): duplicate part of the
gtk_widget_real_destroy () functionality.
(gtk_widget_real_destroy): reinitialize with a new style, instead
of setting widget->style to NULL.
Fri May 5 13:02:09 2000 Tim Janik <timj@gtk.org>
* gtk/gtkcalendar.c:
* gtk/gtkbutton.c: ported _get_type() implementation over to
GType, either to preserve memchunks allocation facilities,
or because Gtk+ 1.0 GtkTypeInfo was still being used.
* gtk/gtkobject.[hc]: derive from GObject. ported various functions
over. prepare for ::destroy to be emitted multiple times.
removed reference tracer magic. chain into GObjectClass.shutdown()
to emit ::destroy signal.
* gtk/gtksignal.c: removed assumptions about GTK_TYPE_OBJECT being
fundamental.
* gtk/gtkmain.c: removed gtk_object_post_arg_parsing_init()
cludge.
* gtk/gtksocket.c:
* gtk/gtkplug.c:
* gtk/gtklayout.c:
* gtk/gtklabel.c:
* gtk/gtkargcollector.c:
* gtk/gtkarg.c: various fixups to work with GTK_TYPE_OBJECT
not being a fundamental anymore, and to work with the new
type system (nuked fundamental type varargs clutter).
* gtk/*.c: install finalize handlers in the GObjectClass
part of the class structure.
changed direct GTK_OBJECT()->klass accesses to
GTK_*_GET_CLASS().
changed direct object_class->type accesses to GTK_CLASS_TYPE().
* gtktypeutils.[hc]: use the reserved fundamental ids provided by
GType. made most of the GTK_*() type macros and Gtk* typedefs
simple wrappers around macros and types provided by GType.
most notably, a significant portion of the old API vanished:
GTK_TYPE_MAKE(),
GTK_TYPE_SEQNO(),
GTK_TYPE_FLAT_FIRST, GTK_TYPE_FLAT_LAST,
GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST,
GTK_TYPE_ARGS,
GTK_TYPE_CALLBACK,
GTK_TYPE_C_CALLBACK,
GTK_TYPE_FOREIGN,
GtkTypeQuery,
gtk_type_query(),
gtk_type_set_varargs_type(),
gtk_type_get_varargs_type(),
gtk_type_check_object_cast(),
gtk_type_check_class_cast(),
gtk_type_describe_tree(),
gtk_type_describe_heritage(),
gtk_type_free(),
gtk_type_children_types(),
gtk_type_set_chunk_alloc(),
gtk_type_register_enum(),
gtk_type_register_flags(),
gtk_type_parent_class().
replacements, where available are described in ../docs/Changes-1.4.txt.
implemented compatibility functions for the remaining API.
* configure.in: depend on glib 1.3.1, use gobject module.
2000-02-19 Anders Carlsson <andersca@gnu.org>
* gtk/gtkrange.c (gtk_range_scroll_event): Return TRUE
to prevent the scroll event to be propagated upwards.
Fri Feb 18 14:37:29 2000 Owen Taylor <otaylor@redhat.com>
* gdk/x11/gdkwindow-x11.c (gdk_event_mask_table): Remove
OwnerGrabButtonMask from button entries for
GDK_BUTTON_PRESS / GDK_BUTTON_RELEASE.
* gtk/gtklayout.c (gtk_layout_realize): Always add GDK_SCROLL
to the event mask (which will result in button/press release
being added to the event mask on Unix) so scrolling works
for layouts in scroll windows.
* gdk/gdkevents.h (enum): Fix up GDK_ALL_EVENTS_MASK.
Patch from Anders Carlsson <andersca@picard.andersnet> to add
a scroll event.
* gtk/testgtk.c (scroll_test_scroll): Added an example of mouse wheel
scrolling to the "Test Scrolling" part of testgtk.
* gtk/gtkwidget.h (struct _GtkWidgetClass): Added scroll_event signal.
* gtk/gtkwidget.c: Added "scroll_event" GTK+ signal and matched
it against GDK_SCROLL.
* gtk/gtkrange.c (gtk_range_scroll_event): Updated to use the new
way of mouse wheel scrolling.
* gtk/gtkscrolledwindow.c (gtk_scrolled_window_scroll_event): Likewise.
* gtk/gtkspinbutton.c (gtk_spin_button_scroll): Likewise.
* gtk/gtkmain.c: Removed previous mouse wheel hack.
* gdk/x11/gdkwindow-x11.c (gdk_event_mask_table): Added entry in
gdk_event_mask_table.
* gdk/x11/gdkevents-x11.c (gdk_event_translate): Added
GdkEventScroll handler.
* gdk/gdkevents.h: Added GdkEventScroll structure.
should break on Unix/X11.
Win32 merge and general portability stuff:
* acconfig.h,configure.in: Check for <sys/time.h>.
* gdk/win32: New directory (actually, been there for a while).
* gtk/fnmatch.c: Include <glib.h> for G_DIR_SEPARATOR, WIN32 and
NATIVE_WIN32, and use these. Always case fold on Win32. No
backslashed escapes on native Win32.
* gtk/{gtk.def,makefile.msc}: New files.
* gtk/Makefile.am: Add above new files.
* gtk/{gtkaccelgroup,gtkbindings}.c: Include <string.h>
instead of <strings.h>.
* gtk/{gtkcalendar,gtkitemfactory,gtkpreview,gtkrc}.c: Include
config.h. Protect inclusion of <sys/param.h>, <sys/time.h>, and
<unistd.h> appropriately.
* gtk/gtkdnd.c: Merge in Win32 version (which doesn't do much).
Use ABS() (from <glib.h>) instead of abs().
* gtk/gtkfilesel.c: Moved Win32-specific includes after inclusion
of gtk (and thus glib) headers, so that WIN32 will be
defined. With MS C, include <direct.h> for mkdir prototype.
* gtk/gtkitemfactory.c (gtk_item_factory_callback_marshal): Add
some casts, needed by MS C.
* gtk/{gtklayout,gtkplug}.c: Merge in Win32 version (which isn't
implemented).

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.

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.
* configure.in gdk/gdkevents.c: Removed attempts to
subtract base_id, which were already non-functional.
I submitted this patch twice to gtk-devel-list, and received no comments, so
am committing it. Although not exhaustively tested, I have been using this
gtk+ for a week w/o problems, and I did read the code to ensure that nothing
ever writes to these data structures. If by chance people encounter SEGV's in
gtk+ code that is setting values in global data structures, this patch could
be a possible culprit.

* configure.in acheader.h gdk/gdkwindow.c
Check for Shape extension both on the client and server
side. (And, more importantly, check for the shape extension
so we may include -lXext even when compiling with --disable-xshm)

necessary.
* gdk/gdkwindow.c: Set ->colormap to NULL for root
and foreign windows. Use this to check if we

^^^^^^^ This is why some many files changed
Even where there were proper prototypes elsewhere.
* gdk/gxid.c (handle_claim_device): Some extra checks.
It isn't safe against being fed bad X id's, but at
least it should be safe against deleting all your
files.
