Change so that updates of selection don't take effect immediately, but

Wed Nov 13 17:03:19 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkcombo.c: Change so that updates of selection
        don't take effect immediately, but only when popdown
        is closed with a button release within the combo
        or Return/Enter.

        * gtk/gtkcombo.c: Support Alt-Down to pop down the
        combo, Alt-Up to pop it back up, Space to immediately
        select current item.

        * gtk/gtkcombo.c (gtk_combo_entry_key_press): Don't
        move the focus when we get to the ends of the list
        entries.

        * gtk/gtkcombo.c: Fix handling of state in ad-hoc
        keybinding handling to be a bit more reasonable.

        * gtk/gtkcombo.c (gtk_combo_popup_list): Clear
        last_focus_child when no item is selected so we
        don't start focusing from some random place.

        * gtk/gtkcombo.c (gtk_combo_init): Make
        gtk_combo_set_use_arrows_always, enable_arrows_always
        properties have no effect, they were an awful idea.
        Always behave as if enable_arrows_always is true.

        * gtk/gtknotebook.c: Fix a warning.

arrow (cursor) keys, though this behaviour can be turned off with
gtk_combo_set_use_arrows().
</para>
<para>
Normally the arrow keys are only active when the contents of the text entry
field matches one of the items in the list. If the contents of the entry field
do not match any of the list items, then pressing the arrow keys does nothing.
However, by calling gtk_combo_set_use_arrows_always() you can specify that the
arrow keys are always active. If the contents of the entry field does not match
any of the items in the list, then pressing the up or down arrow key will set
the entry field to the last or first item in the list, respectively.
