excess newlines and sprinkled some newlines where needed. Zero

* gtk/gtk.h: define __GTK_H_INSIDE__ around including all other
headers.
* gtk/gtktypebuiltins.h.template
* gtk/gtkversion.h.in
* gtk/gtk*.h: add single-include guards that #error out if
GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
included individually.
* gtk/gtkprintbackend.h
* gtk/gtkprinter-private.h
* gtk/gtktextlayout.h
* gtk/gtktexttagprivate.h
* gtk/gtktexttypes.h
* gtk/gtktreedatalist.h: include <gtk/gtk.h> instead of individual
headers in these private or semi-private headers.
* gtk/gtkimmodule.h: also here because it's not in gtk.h.

instead of individual headers in these deprecated headers. They
don't get included at all when GTK_DISABLE_DEPRECATED is defined,
so if an app needs them anyway, it must undef GTK_DISABLE_DEPRECATED
and include them individually, which should continue to work.
* gtk/gtkclist.c: include "gtkctree.h" because of the change
above.

* gtk/gtktreeview.h:
* gtk/gtktreeview.c:
* gtk/gtktreeprivate.h: Add a new boolean property
::hover-expand and make the treeview expand/collapse rows
on mouseover if it is set.
2004-07-07 Matthias Clasen <mclasen@redhat.com>
Support separators in combo boxes and more generally in tree
views (#135873):
* gtk/gtkcombobox.h:
* gtk/gtkcombobox.c (gtk_combo_box_get_row_separator_column):
* gtk/gtkcombobox.c (gtk_combo_box_set_row_separator_column):
Add a ::row-separator-column property with getter and setter,
which can indicate a boolean model column to determine which
rows are separators.
* gtk/gtkcombobox.c: Display separator rows as separator menu
items in menu mode, and by using the new treeview separator
functionality in list mode.
* gtk/gtktreeview.h:
* gtk/gtktreeview.c (gtk_tree_view_get_row_separator_func):
* gtk/gtktreeview.c (gtk_tree_view_set_row_separator_func):
Add a callback to determine whether a row is a separator.
* gtk/gtktreeview.c (gtk_tree_view_bin_expose):
* gtk/gtktreeview.c (gtk_tree_view_create_row_drag_icon):
* gtk/gtktreeview.c (validate_row): Use the new callback
to determine whether a row is a separator, and draw it
as a separator then. Since separators should take up less
vertical space than regular rows, this requires removing
the redundant MAX(...,expander_size) calls which appear in
many places. Instead, the MAX() is now only done in
validate_row(), and only if the row is not a separator.
To catch possible side effects of this intrusive change,
I have left EXPANDER_MAX() calls in place of the MAX() calls
which will emit a warning if something breaks. They should
be removed before 2.6.
* gtk/gtktreeselection.c (row_is_selectable): Don't let
separator rows be selected.
* tests/testcombo.c (create_blaat): Add a separator column.

* gtk/gtktreeview.c: Add a new property "hover_selection", which
when TRUE makes the selection follow the mouse. Also add setter
and getter for the fixed_height property.
Tue Nov 26 22:26:04 2002 Kristian Rietveld <kris@gtk.org>
* gtk/gtk{tree,list}store.c (gtk_{tree,list}_store_real_set_value):
add a gtk_list_store_sort_iter_changed line for some special
case ... (#96647 (issue 1), testcases from Soeren Sandmann and
Daniel Elstner).
Tue Nov 26 22:18:06 2002 Kristian Rietveld <kris@gtk.org>

(gtk_default_draw_option): support drawing inconsistent
options/checks for cells.
Tue Nov 26 22:14:14 2002 Kristian Rietveld <kris@gtk.org>
* gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_editing_done),
(gtk_cell_renderer_text_start_editing): add a focus_out_id to avoid
calling _editing_done twice (which has nasty side-effects). (#96647,
(issue 2) testcase from Soeren Sandmann).

Tue Nov 26 22:06:29 2002 Kristian Rietveld <kris@gtk.org>
Yes, this chunk breaks ABI compatibility. Owen knows about it and
agreed with it. It doesn't break ABI that bad though, things will
still work. Please keep it silent :P.
This patch fixes some keynav issues reported by Narayana Pattipati
in #81633. (Also mentioned in #92037 (Sun tracking bug)).
* gtk/gtkmarshalers.list: add two silly marshalers

entries in GtkTreeViewClass,

bad focus loop.

Still can't drop _to_ the left tree, but other places
work.
* gtk/gtktreeview.c (unset_reorderable): Unset the
reorderable property if unset/enable_model_drag_source/dest
are called manually.

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.
Fri Jun 8 18:52:10 2001 Jonathan Blandford <jrb@redhat.com>
* gtk/gtktreeview.[hc]: Patch Thomas Broyer from
<tbroyer@ltgt.net>. Expander arrows are now attached to a specific
column and follow it when draged, rather than a location in the
view. "expander_column" property and drawing functions changed
accordingly. Fixes bug #55942.
(gtk_tree_view_{set,get}_expander_column): Now works with a
GtkTreeViewColumn* instead of int.

sense. (#55767)

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().
