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.
