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. The patch handles configurable beeping, navigating the GUI with cursor keys only (as in phone environments), and configurable wrap-around. 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. Should look at gtk-keynav-wrap-around too, will look into that.

* gtk_icon_view_scroll_to_path:
* @icon_view: A #GtkIconView.
* @path: The path of the item to move to.
* @use_align: whether to use alignment arguments, or %FALSE.
* @row_align: The vertical alignment of the item specified by @path.
* @col_align: The horizontal alignment of the item specified by @path.
*
* Moves the alignments of @icon_view to the position specified by @path.
* @row_align determines where the row is placed, and @col_align determines
* where @column is placed. Both are expected to be between 0.0 and 1.0.
* 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means
* center.
*
* If @use_align is %FALSE, then the alignment arguments are ignored, and the
* tree does the minimum amount of work to scroll the item onto the screen.
* This means that the item will be scrolled to the edge closest to its current
* position. If the item is currently visible on the screen, nothing is done.
*
* This function only works if the model is set, and @path is a valid row on
* the model. If the model changes before the @icon_view is realized, the
* centered path will be modified to reflect this change.
*
* Since: 2.8
