Thu Jan 21 16:03:02 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtktreeitem.c: Add a paint routine, fix up bugs
in drawing where if the expose area was contained
completely in the right side of the tree the background
wasn't redraw, etc.
Fri Jan 15 10:22:21 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkwidget.c (gtk_widget_class_init):
nparams for selection_get should be 3, not 2.
[ From Damon Chaplin <damon@karuna.freeserve.co.uk> ]
* gtk/gtkeventbox.c (gtk_event_box_paint): Add a paint
routine so queued redraws work inside event boxes.
Thu Jan 14 17:47:37 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkentry.c (gtk_entry_draw_cursor_on_drawable): Only
redraw character under cursor when not displaying
highlighted selection.
* gdk/gdkrgb.c (gdk_rgb_init): Add in a cast to
gpointer to make IRIX cc happy.
Thu Jan 14 12:29:50 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkcheckbutton.c (gtk_check_button_draw): Restructure
the drawing code to remove a bit of duplication -
and to remove a call to gtk_widget_draw_focus()
that queues a redraw when an expose occurs.
* gtk/gtklabel.c (gtk_label_expose): Fix up handling
of ypadding.
* gtk/gtknotebook.c (gtk_notebook_draw): If we redraw
the whole widget, also redraw the corresponding
areas of the child widget. (have_visible_child
still has some problems)
* gdk/gdkpixmap.c: Change some g_new's to g_new0 so
that fields unused for pixmaps get initialzized
sanely.
* gdk/gdk.h gdk/gdkwindow.c gdk/gdkprivate.h: Add new calls
gdk_window_is_visible() and gdk_window_is_viewable()
and a mapped flag to the window private structure.
* gtk/gtkbin.c gtk/gtkclist.c gtk/gtkfixed.c gtk/gtkitem.c
gtk/gtklayout.c gtk/gtklist.c gtk/gtkmenushell.c
gtk/gtknotebook.c gtk/gtkpaned.c gtk/gtktree.c
gtk/gtktreeitem.c gtk/gtkviewport.c:
Map windows after mapping children.
* gtk/gtkwidget.c (gtk_widget_clip_rect): Handle
rectangles completely clipped away correctly.
* gtk/gtkwidget.c (gtk_widget_idle_draw): Don't
call gtk_widget_draw if width or height is 0.
* gtk/gtkwidget.c (gtk_widget_idle_draw): Don't
rely on GTK_REDRAW_PENDING after we've cleared
it. (This was causing draw-combining to not
happen at all).
* gtk/gtkbin.c gtk/gtkscale.c: Remove uneccessary calls
to gtk_widget_queue_draw() when mapping.
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.
1998-11-30 Elliot Lee <sopwith@cuc.ml.org>
* {gdk,gtk}/*.c: Make read-only data structures "static const" to
allow them to be shared, mainly including (but not limited to) the
GtkTypeInfo structures for each class.
* gtk/gtkfilesel.c: Add /net to the "leave me alone" directory listing.
Thu Sep 3 04:22:20 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmenushell.c (gtk_real_menu_shell_move_current):
GTK_MENU_DIR_CHILD: check for the existance of
menu_shell->active_menu_item before accessing its child.
GTK_MENU_DIR_PREV:
GTK_MENU_DIR_NEXT: if we haven't had an active item and still
don't, make a default selection.
Wed Sep 2 00:28:58 1998 Tim Janik <timj@gtk.org>
* gtk/gtkwidget.c (gtk_widget_propagate_state): iterate
the children with _forall for sensitivity changes and with
_foreach on pure state changes. this fixes a lot of the
old inclusions of internal widgets into _foreach calls.
* gtk/gtktree.c: removed gtk_tree_foreach, let gtk_tree_forall
do the work. don't walk the subtrees of first level children.
* gtk/gtktreeitem.c: provide a _forall implementation,
which walks the subtrees as well for include_internals.
* gtk/gtkmenuitem.c: provide a _forall implementation, which walks
the submenus as well for include_internals.
* gtk/gtkscrolledwindow.c: removed gtk_scrolled_window_foreach and
implemented gtk_scrolled_window_forall, which will iterate over
the viewport and the scrollbars for gtk_container_forall or
iterate over the viewports children for gtk_container_foreach.
* gtk/gtktoolbar.c:
* gtk/gtktable.c:
* gtk/gtkpaned.c:
* gtk/gtkpacker.c:
* gtk/gtkmenushell.c:
* gtk/gtklist.c:
* gtk/gtkfixed.c:
* gtk/gtkclist.c:
* gtk/gtkbox.c:
* gtk/gtkbin.c:
* gtk/gtknotebook.c:
removed the old gtk_*_foreach functions and provided gtk_*_forall.
* gtk/gtknotebook.c:
(gtk_notebook_real_switch_page): expose tabs.
(gtk_notebook_page_num): new function to return the page number
of a distinct child.
(gtk_notebook_focus): minor fixups. foxus handling is still screwed
under some circumstances.
* gtk/gtktreeitem.c:
(gtk_real_tree_item_select):
(gtk_real_tree_item_deselect): major fixes.
some general fixups wrt queue_redraw, and tree items not being
NO_WINDOW widgets.
* gtk/gtklistitem.c:
(gtk_real_list_item_select):
(gtk_real_list_item_deselect):
(gtk_real_list_item_toggle):
removed unneccessary queue_redraw calls.
Wed Aug 30 09:42:07 1998 Tim Janik <timj@gtk.org>
* gtk/gtkoptionmenu.c: allow optionmenus to have the focus and
automatically popup the menu on space bar.
Wed Aug 26 06:40:34 1998 Tim Janik <timj@gtk.org>
* gtk/gtkcontainer.h:
* gtk/gtkcontainer.c: implemented gtk_container_forall() (as a class
method), which acts similar to gtk_container_foreach(), but iterates
over internal children. the GtkContainer::foreach signal vanished in
favour of a new class method ->forall() that optionally includes
internal widgets.
* gtk/gtkclist.c (gtk_clist_init): provide no _foreach implementation
but a _forall implementation, since all child widgets we have are
internal ones.
(column_button_create): set the parent window prior
to gtk_widget_set_parent().
* gtk/gtkwidget.c:
exchanged all calls to gtk_container_foreach() with
gtk_container_forall().
* gtk/gtkwidget.h:
* gtk/gtkwidget.c: added the GTK_COMPOSITE_CHILD, exported through
the GtkWidget::composite_child argument. to have a widget created
with the flag initially, two new functions got added to wrap a widgets
creation:
gtk_widget_push_composite_flag() and gtk_widget_pop_composite_flag().
Wed Aug 25 23:37:39 1998 Tim Janik <timj@gtk.org>
* gtk/gtktooltips.h:
* gtk/gtktooltips.c: exported gtk_tooltips_create_window() as
gtk_tooltips_force_window(), so tooltips->tip_window can be accessed
prior to the first tip being set.
don't put an extra reference on the window, since it is a toplevel,
it wont get destroyed from anywhere else.
* overall macro and GtkType fixups.
Tue Aug 18 03:54:43 1998 Tim Janik <timj@gtk.org>
* gtk/gtkmain.c (gtk_init): restricted the --g*fatal-* arguments
to --g-fatal-warnings again. this option now causes log levels of
WARNING and CRITICAL to abort().
* gdk/gdk.c:
* gdk/gdkdnd.c:
* gdk/gdkcc.c:
* gdk/gdkfont.c:
* gdk/gdkwindow.c:
* gdk/gdkvisual.c:

* gtk/gtkobject.c:
* gtk/gtkpreview.c:
* gtk/gtkselection.c:
* gtk/gtktext.c:
* gtk/gtktree.c:
* gtk/gtktreeitem.c:
did a global search&replace to substitute g_print() calls with
g_message(). libraries shouldn't use printf(), g_print() or
g_printerr() at all.
a bunch of the replacements should probably be wrapped into the
G{D|T}K_NOTE() macros, so they are special cased for debugging
purposes in a sane way, avoiding all the nasty #ifdef DEBUG_MY_TEDDY
things.
* gdk/gdkrgb.c: left this out currently.
* gdk/gdkdnd.c: added copyright notice.
Use common marshalling routines instead of having widget-private ones.
It compiles & links.
testgtk segfaults. I'm convinced that is Somebody Else's Problem
(marshalling routine gets func_data=0x0 and blithely passes it on) but the
fact that it happens now & not before makes me wrong :-)
Sat Jul 4 13:16:24 1998 Tim Janik <timj@gtk.org>
* gtk/*.c: changed reversed_[12] to reserved_[12] in gtk_*_get_type
functions.
* gdk/gdkwindow.c:
* gdk/gdkvisual.c: check for some pointer values to be != NULL, prior
to XFree() calls.
Sun Jun 28 04:29:10 1998 Tim Janik <timj@gtk.org>
* gtk/gtktypeutils.c (gtk_type_class_init): call the base class init
fucntions from all parent types upon class initialization.
* gtk/gtkcontainer.c:
(gtk_container_get_type): announce gtk_container_base_class_init to
the type system.
(gtk_container_base_class_init): new function to feature base class
initialization.
(gtk_container_get_child_arg):
(gtk_container_set_child_arg): call the GtkContainerClass get_child_arg
and set_child_arg methods of the class indicated through the argument
name.

(gtk_object_base_class_init): new function to feature base class
initialization.
(gtk_object_init_type): announce gtk_object_base_class_init to the type
system.
(gtk_object_class_init): setup the get_arg and set_arg pointers for
GtkObjectClass.
(gtk_object_setv):
(gtk_object_getv): call the GtkObjectClass get_arg and set_arg methods,
instead of bothering the type system with this.
* gtk/gtkaccellabel.c:

* gtk/gtkpacker.c:
* gtk/gtkwidget.c:
* gtk/gtkwindow.c:
* gtk/gtkframe.c:
* gtk/gtkmisc.c:
* gtk/gtklabel.c: set the object_class->{g|s}et_arg pointers to the
corresponding gtk_*_{g|s]et_arg functions and updated the gtk_*_get_type
functions wrt GtkTypeInfo initialization. changed a lot of the set/get
arg functions to take a GtkObject argument.

Sun May 3 13:38:22 1998 Owen Taylor <otaylor@gtk.org>
* 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)
Don't set override_redirect on all shaped windows. It isn't
necessary.
* gdk/gdkwindow.c: Set ->colormap to NULL for root
and foreign windows. Use this to check if we
need to get the colormap from X.
Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org>
* gtk/gtkbutton.c (gtk_button_paint): Draw the areas
between the default and the button always in GTK_STATE_NORMAL.
* gtk/gtkrange.c (gtk_range_style_set): Added a style_set
callback.
Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org>
* gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]):
Fix a buffer overflow on pixmaps that claim to have
more than 31 characters per pixel.
(gdk_pixmap_read_string): Don't wrap around strings longer
than half of address space ;-)
* gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers
that were used for printing integers.
* */* (almost):
Style: All
int foo () { ... }
changed to
int foo (void) { ... }
^^^^^^^ 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.
Tue Apr 7 19:36:48 1998 Owen Taylor <owt1@cornell.edu>
* gutils.c (g_direct_compare): Removed, because that's what
a NULL comparison function means. And it wasn't 64 bit safe.
Tue Apr 7 19:14:03 1998 Owen Taylor <owt1@cornell.edu>
* gdk/gdkpixmap.c: Added maximum field widths to prevent
possible '%s' scanf overflows. Replaced scanf("%c")
with getc(), Don't interpret /*/ as a full comment. Use
g_realloc/g_new.
* gtk/gtkwidget.h gtk/gtkprivate.h: Changed all flag
tests to check for ((GTK_WIDGET_FLAGS(widget) & FLAG) != 0)
instead of (GTK_WIDGET_FLAGS(widget) & FLAG)
* gtk/gtkfilesel.c: Use getwd() instead of getcwd() on
SunOS, because getcwd() hangs up in a wait4().
(Found by David Monniaux <monniaux@clipper.ens.fr>)
- Check device/inode/mtime not just inode/mtime, when
caching scanned directories.
(From: scottk@ig.utexas.edu (Scott Kempf))
* gdk/gdkpixmap.c: Check for 0 width/height when
creating pixmaps.
* gtk/*.c: Global substitution of recently introduced
"MAX (0," for allocations to "MAX (1,", since
creating a backing pixmap with a zero width or height
fails.
* gdk/gdkwindow.c (gdk_window_new): Don't set all the
WM properties for child windows. Don't set the base
size, since the value we set will be taken as a minimum
size.
Fri Apr 3 17:14:55 1998 Owen Taylor <owt1@cornell.edu>
* gdk/gdk.c: More extensive debugging output
* gtk/gtkalignment.c gtk/gtkbutton.c gtk/gtkcheckbutton.c

gtk/gtkmenu.c gtk/gtkmenubar.c gtk/gtkmenuitem.c
gtk/gtknotebook.c gtk/gtktable.c gtk/gtktree.c
gtk/gtktreeitem.c gtk/gtkviewport.c
Avoid assigning negative values to unsigned allocation.width and
height
* gtk/gtkwindow.c:
Instead of realizing the widget, then size allocating, (resulting
in XMoveResizeWindows for all children, do the size allocation
first, then realize.
In gtk_real_window_move_resize, combine move and resize
into a single GDK/X call when possible.
* gtk/gtkclist.c gtk/gtkdrawingarea.c:
Remove assumption that the widget will be size allocated _after_
it is realized.
* gtk/gtklist.c (gtk_list_motion_notify): Removed useless
debugging message.
Wed Mar 11 04:35:06 1998 Tim Janik <timj@gimp.org>
* gtk/gtklist.c:
* gtk/gtktree.h:
* gtk/gtktree.c:
* gtk/gtktreeitem.h:
* gtk/gtktreeitem.c: applied gtk-bolliet-980310-0.patch.gz which adds
more checks and implements gtk_tree_clear_items. made a bunch of style
and indentation fixes.
Mon Mar 9 15:48:10 1998 Tim Janik <timj@gimp.org>

* gtk/gtktree.c:
* gtk/gtktreeitem.c:
* gtk/gtkwidget.c:
* gtk/gtktogglebutton.c:
* gtk/gtkwindow.c:
made the <widget>_signals[] arrays of type guint rather than gint.
* gtk/gtkwidget.c (gtk_widget_get_ancestor): made widget_type a GtkType.
* gtk/gtkcombo.h:
handler ids need to be of type guint (entry_change_id, list_change_id).
* gtk/gtkaccelerator.c:
changed signal_num to signal_id and typed it guint.
* gtk/gtkmain.c: made gtk_ndebug_keys a guint.
* gtk/gtkmenu.h:
* gtk/gtkmenu.c:
(gtk_menu_popup): made button a guint.
(gtk_menu_set_active): made index a guint.
* gtk/gtkmenuitem.h:

(gtk_option_menu_set_history): made index a guint.
* gtk/gtksignal.h:
* gtk/gtksignal.c:

than gints. also made some conversions from guint to GtkType, left over
from when the fundamental-types system was introduced.
* gtk/gtkobject.h:
* gtk/gtkobject.c: made object_data_id_index and obj_count guints.
made *signals and nsignals guints in GtkObjectClass.
Sun Mar 8 15:53:33 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c:
- Show selection correctly when starting selection with arrows
- Display pixmap background only when not editable
- Redraw focus area more carefully to prevent flashing (and
make style of drawing consistent with Entry)
* gtk/gtktreeitem.c: ref colormaps for pixmap by colormap
storage.
* gtk/gtkrc.c: Store a separate style for each RcStyle for
each colormap, so we can handle background pixmaps
correctly, which need to be per-colormap. (Leaks
colormaps...)
Parse text color style entries correctly.
* gtk/testgtk.c: insert text without fg color
gtk/testgtkrc: move "*" after rest, so the other class styles
take effect
* gdk/gdkwindow.c gdk/gdk.c gdk/gdkprivate.h: Send DND events
safely, in case drop window disappears. (Performance hit
because XSync()'s are necessary)
* gdk/gdk.h gdk/gdkpixmap.c: Added
gdk_pixmap_colormap_create_from_xpm[_d] to allow creating
pixmaps from xpm's before you have a GdkWindow.
Thu Mar 5 01:22:06 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtkwidget.c (gtk_widget_unparent): Unset allocation
on unparent, to force reallocation if we get adding back
to a new parent which is already size-allocated.
* gtk/gtktreeitem.c: Keep track of separate +/- pixmaps
for each colormap, removed the idle hack.
* gdk/gdk.c: Don't warn when unable to open XIM method,
since X11R5 apparently has no default method.
* gtk/gtkwidget.c (gtk_widget_set_style_internal): Don't
call size_request on initial emission - since the
widget size isn't set yet, it can't change.
* gtk/Makefile.am: New rules 'test' and 'test-debug' to run
testgtk with the correct working directory.
* gtk/gtkentry.c (gtk_move_forward_word):
Check for position at end of line.
* gtk/gtkinputdialog.h (struct _GtkInputDialogClass):
removed 'gpointer data' arguments from default handler
structures.
Sun Mar 1 15:18:38 PST 1998 Shawn T. Amundson <amundson@gimp.org>
* Required changes for version change to 0.99.4
* gtk/gtktree.[ch]: patch from J. Bolliet to correct some bugs
* gtk/testgtk.c: added test here from J. Bolliet, removed testtree
* gtk/clist: gtk-abilleira-981602-0, allows gtk_clist_set_pixmap
and gtk_clist_set_pixtext to not require a mask
* gdk/gdkdraw.c,gdk.h: gtk-trow-980217-0
adds gdk_draw_lines and fixes some things about
gdk_draw_polygon
Sat Feb 21 14:49:17 1998 Tim Janik <timj@gimp.org>
* gtk/gtkobject.h:
* gtk/gtkobject.c: gtk_object_query_args takes an additional pointer
now which if supplied will point to an array holding the sequential
argument ids.
* gtk/gtktree.c: fix emission of selection_changed signal, supplied
by Bolliet Jerome.
* gtk/gtktreeitem.c: inline the plus and minus pixmaps, supplied by
Bolliet Jerome.
* gtk/gtknotebook.c: do a resize when a page is removed and don't
refer to the removed page on the switch signal, supplied by Lars Hamann
and Stefan Jeske.
* gtk/gtktoolbar.h:
* gtk/gtktoolbar.c:
gtk_toolbar_append_item, gtk_toolbar_prepend_item,
gtk_toolbar_insert_item, gtk_toolbar_append_widget,
gtk_toolbar_prepend_widget, gtk_toolbar_insert_widget: take an additional
gchar *tooltip_private_text as argument to fully support the underlying
call to gtk_tooltip_set_tip.
(made the ChangeLog catch up with my last commits).
* gtk/gtkentry.c gtk/gtkinputdialog.c gtk/gtklist.c
gtk/gtklistitem.c gtktree.c gtk/gtktreeitem.c testgtkrc:
Change style->white to style->base[] where appropriate.
Change the default style to make this apparent. (Yes, it's
ugly... it can be removed later)
Corrects a bug in gtk_tree_remove_items and gtk_tree_item_destroy.
Adds the possibility to connect all items by lines. This is the
default now. You can overide this with the function
gtk_tree_set_view_line which take a tree and a boolean.
This tree widget looks way more finished with the lines. Very
nice. Check it out and run gtk/testtree.
