added rc-style argument GtkSpinButton::shadow_type. removed Sun Mar 18 01:15:30 2001 Tim Janik <timj@gtk.org> * gtk/gtkspinbutton.[hc]: added rc-style argument GtkSpinButton::shadow_type. removed spin_button->shadow_type, gtk_spin_button_set_shadow_type() and ARG_SHADOW_TYPE as it doesn' make much sense to try to override rc-style settings. * gtk/gtkfixed.c: removed gtk_fixed_paint() (was unused). * gtk/gtkwidget.c: quark cleanups. * gtk/gtkrc.[hc]: added gtk_rc_scanner_new() to create an rc-file scanner with appropriate configuration, renamed GtkRcStyleClass.clone to create_rc_style() (we don't do cloning in standard OO sense). added per rc style properties. * gtk/gtkstyle.[hc]: added code to retrive pspec conformant rc-style property values and for caching those. some cleanups. * gtk/Makefile.am: -DG_DISABLE_CONST_RETURNS. * gtk/gtksettings.[hc]: new file for global rc-file properties (at least currently, should get extended to support X properties and other communication mechanisms). * gtk/gtkwidget.[hc]: added style property support: (gtk_widget_class_install_style_property_parser): install style property pspec with parser function for rc-file values other than LONG, DOUBLE or STRING. (gtk_widget_class_install_style_property): same as above without parser (parsers are going to be needed quite infrequently). (gtk_widget_style_get_property): retrive style property value. (gtk_widget_style_get_valist): same as above with varargs support, has NOCOPY semantics. (gtk_widget_style_get): wrapper around gtk_widget_style_get_valist().

* SECTION:gtkspinbutton
* @Title: GtkSpinButton
* @Short_description: Retrieve an integer or floating-point number from
* the user
* @See_also: #GtkEntry
*
* A #GtkSpinButton is an ideal way to allow the user to set the value of
* some attribute. Rather than having to directly type a number into a
* #GtkEntry, GtkSpinButton allows the user to click on one of two arrows
* to increment or decrement the displayed value. A value can still be
* typed in, with the bonus that it can be checked to ensure it is in a
* given range.
*
* The main properties of a GtkSpinButton are through an adjustment.
* See the #GtkAdjustment section for more details about an adjustment's
* properties.
*
* <example>
* <title>Using a GtkSpinButton to get an integer</title>

documented necessary changes for 1.4 transition. 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.

Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

added rc-style argument GtkSpinButton::shadow_type. removed Sun Mar 18 01:15:30 2001 Tim Janik <timj@gtk.org> * gtk/gtkspinbutton.[hc]: added rc-style argument GtkSpinButton::shadow_type. removed spin_button->shadow_type, gtk_spin_button_set_shadow_type() and ARG_SHADOW_TYPE as it doesn' make much sense to try to override rc-style settings. * gtk/gtkfixed.c: removed gtk_fixed_paint() (was unused). * gtk/gtkwidget.c: quark cleanups. * gtk/gtkrc.[hc]: added gtk_rc_scanner_new() to create an rc-file scanner with appropriate configuration, renamed GtkRcStyleClass.clone to create_rc_style() (we don't do cloning in standard OO sense). added per rc style properties. * gtk/gtkstyle.[hc]: added code to retrive pspec conformant rc-style property values and for caching those. some cleanups. * gtk/Makefile.am: -DG_DISABLE_CONST_RETURNS. * gtk/gtksettings.[hc]: new file for global rc-file properties (at least currently, should get extended to support X properties and other communication mechanisms). * gtk/gtkwidget.[hc]: added style property support: (gtk_widget_class_install_style_property_parser): install style property pspec with parser function for rc-file values other than LONG, DOUBLE or STRING. (gtk_widget_class_install_style_property): same as above without parser (parsers are going to be needed quite infrequently). (gtk_widget_style_get_property): retrive style property value. (gtk_widget_style_get_valist): same as above with varargs support, has NOCOPY semantics. (gtk_widget_style_get): wrapper around gtk_widget_style_get_valist().

(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.

Patch from Bill Haneman (with many modifications) to make the focus color 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().

Add new infrastructure for notifications of failed keyboard navigation and 2006-11-16 Michael Natterer <mitch@imendio.com> Add new infrastructure for notifications of failed keyboard navigation and navigation with restricted set of keys.

Fixes bugs #322640, #70986, #318827, #334726, #334742 and #309291. * gtk/gtksettings.c: added properties gtk-keynav-cursor-only, gtk-keynav-wrap-around and gtk-error-bell. * gtk/gtkwidget.[ch]: added new signal "keynav-failed" and public API to emit it. Added New function gtk_widget_error_bell() which looks at the gtk-error-bell setting and calls gdk_window_beep() accordingly. * gtk/gtk.symbols: add the new widget symbols. * gtk/gtkcellrendereraccel.c * gtk/gtkimcontextsimple.c * gtk/gtkmenu.c * gtk/gtknotebook.c: use gtk_widget_error_bell() or look at the gtk-error-bell setting instead of calling gdk_display_beep() unconditionally. * gtk/gtkcombobox.c * gtk/gtkentry.c * gtk/gtkiconview.c * gtk/gtklabel.c * gtk/gtkmenushell.c * gtk/gtkspinbutton.c * gtk/gtktextview.c * gtk/gtktreeview.c: call gtk_widget_error_bell() on failed keynav. * gtk/gtkentry.c * gtk/gtklabel.c * gtk/gtkrange.c * gtk/gtktextview.c: consult gtk_widget_keynav_failed() on failed cursor navigation and leave the widget if it returns FALSE. * gtk/gtkmenushell.c * gtk/gtknotebook.c: only wrap around if gtk-keynav-wrap-around is TRUE. * gtk/gtkradiobutton.c: ask gtk_widget_keynav_failed() to decide whether to to wrap-around, and don't select active items on cursor navigation if gtk-keynav-cursor-only is TRUE.

Added New function gtk_widget_error_bell() which looks at the gtk-error-bell setting and calls gdk_window_beep() accordingly. * gtk/gtk.symbols: add the new widget symbols. * gtk/gtkcellrendereraccel.c * gtk/gtkimcontextsimple.c * gtk/gtkmenu.c * gtk/gtknotebook.c: use gtk_widget_error_bell() or look at the gtk-error-bell setting instead of calling gdk_display_beep() unconditionally. * gtk/gtkcombobox.c * gtk/gtkentry.c * gtk/gtkiconview.c * gtk/gtklabel.c * gtk/gtkmenushell.c * gtk/gtkspinbutton.c * gtk/gtktextview.c * gtk/gtktreeview.c: call gtk_widget_error_bell() on failed keynav. * gtk/gtkentry.c * gtk/gtklabel.c * gtk/gtkrange.c * gtk/gtktextview.c: consult gtk_widget_keynav_failed() on failed cursor navigation and leave the widget if it returns FALSE. * gtk/gtkmenushell.c * gtk/gtknotebook.c: only wrap around if gtk-keynav-wrap-around is TRUE. * gtk/gtkradiobutton.c: ask gtk_widget_keynav_failed() to decide whether to to wrap-around, and don't select active items on cursor navigation if gtk-keynav-cursor-only is TRUE. Should look at gtk-keynav-wrap-around too, will look into that.
