group.
2006-06-16 Matthias Clasen <mclasen@redhat.com>

label out of the button box. (#339456, Christian Persch)
2006-06-16 Matthias Clasen <mclasen@redhat.com>
* configure.in: Require cvs glib.
* gtk/gtkprintoperation-unix.c:
(_gtk_print_operation_platform_backend_create_preview_surface):
Don't use a temporary directory for preview files, since it
is not clear who cleans it up. Instead, use g_mkstemp() directly
to create a temp pdf file, and make the preview app responsible
for cleaning it up.
2006-06-16 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkprintoperation-unix.c:
* gtk/gtkprintbackend.c: Move the registration of the
gtk-print-preview-command setting from gtkprintbackend.c to
gtkprintoperation-unix.c, to make sure it is registered before
the first use. Also, document the two settings.
2006-06-16 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkprintoperation-unix.c (handle_print_response): When starting
a preview from the print dialog, set the action to PREVIEW.

Fri Jun 16 11:49:53 2006 Tim Janik <timj@imendio.com>
* fixed#337882 by applying patches from Tommi Komulainen:
* gtk/gtkprogressbar.c:
(gtk_progress_bar_paint_activity):
(gtk_progress_bar_get_activity): Move activity bar offset and size
calculations to separate function.
(gtk_progress_bar_paint_text): Allow caller to specify offset for the
prelight part in addition to width.
(gtk_progress_bar_paint): Paint the text also in activity mode, #337882.
* gtk/gtkprogressbar.c: (gtk_progress_bar_paint_text): Paint the
prelighted text on top of the normal rather than side by side, to
simplify painting text in activity mode.
2006-06-15 Carlos Garnacho <carlosg@gnome.org>
* gtk/gtknotebook.c (gtk_notebook_motion_notify): use
gdk_window_get_pointer() to get pointer coordinates, but limit its
calls to a maximum of 45 times per second for not being too
CPU/network abusive. stop drag operation if (event->state &
GDK_BUTTON1_MASK) is FALSE to prevent tabs from "adhering" to the
pointer. Fixes bug #341571
(gtk_notebook_calculate_tabs_allocation), (gtk_notebook_button_press):
get rid of the "tab jumps to pointer" sensation when beginning a drag
by using the pointer offset in the tab when the drag begins as an
anchor.
(gtk_notebook_redraw_tabs_union): remove, it wasn't worth the little
performance gain and could draw artifacts under some circumstances.
(gtk_notebook_drag_end): do not reparent the detached tab label until
the animation has ended.
2006-06-12 Matthias Clasen <mclasen@redhat.com>

2006-06-09 Benjamin Berg <benjamin@sipsolutions.net>
* gtk/gtkmenuitem.c: (get_offsets): Take GtkMenu::horizontal-padding
into account when placing submenus (#344290)
2006-06-09 Michael Natterer <mitch@imendio.com>
* gtk/gtkrange.c: added new style properties "trough-side-details"
and "draw-trough-under-steppers" and fixed the "stepper-spacing"
style property. Fixes bugs #342339 and #342249.
"draw-trough-under-steppers", when set to FALSE, starts trough
drawing next to the steppers instead of drawing the trough "below"
(around) the steppers. If "stepper-spacing" is set to any value
larger than zero, "draw-trough-under-steppers" is set to FALSE
automatically to avoid rendering an area that looks clickable but
isn't.
(gtk_range_calc_layout): honor draw-trough-under-steppers.
Don't reserve stepper-spacing on sides of the range that don't
have steppers.
(gtk_range_expose): changed drawing accordingly. Implement
"trough-side-details" which enables drawing of the upper and lower
parts of the trough with different details. This is useful for
theme engines which want to draw these parts differently.
(coord_to_value): correctly take all rendering options into
account. stepper-spacing > 0 caused jumping and otherwise
strangely behaving ranges before.
(other functions): changed accordingly.
2006-06-08 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkbutton.c (gtk_button_style_set): Don't call
construct_child here, since some apps make assumptions
about the lifecycle of the constructed label.
2006-06-08 Alexander Larsson <alexl@redhat.com>

Update windows to build with new APIs and first cut

invisible nodes.
