RE: Signals for combobox entry

[Jeff Hallock <Jhallock WBandA com>]

Here are two examples that will exhibit the behavior you desire:

my $combo = Gtk2::ComboBoxEntry->new;
$combo->signal_connect(changed => \&changed);
$combo->signal_connect('focus-out-event' => \&focus_out);

sub changed
{
        my $combo = shift;
        $combo->{changed} = TRUE;
}

sub focus_out
{
        my $combo = shift;
        # commit to database if $combo->{changed};
        $combo->{changed} = FALSE;
}


my $combo = Gtk2::ComboBoxEntry->new;
$combo->signal_connect('focus-in-event'  => \&focus_in);
$combo->signal_connect('focus-out-event' => \&focus_out);

sub focus_in
{
        my $combo = shift;
        $combo->{check} = $comb->get_active_text;
}

sub focus_out
{
        my $combo = shift;
        # commit to database if $combo->{check} ne $comb->get_active_text;
        $combo->{check} = '';
}

Connect to the changed signal of its Entry child?
