$object->Show();
$object->Hide();
$object->IsVisible();

I'm working on it :-)
actually, with beta-301 you can do this:
foreach $under (keys %{$TAB}) {
next if $under =~ /^-/;
print "Found child: $under\n";
}
this relies on the fact that a reference to child is stored in the parent
hash; the "next" row serves to ignore vital data stored in the object too
(eg. -name, -handle, and so on).
to access the actual child object, you can at this point use:
$TAB->{$under}

hmmm... you can put up a perl list to do it:
@page1 = ($Ctrl1, $Ctrl2, $Ctrl3, ...);
# and then...
foreach $control (@page1) {
$control->Show();
}

hope it did help :-)
