Thanks, I did try $text->destroy,etc, but no luck. I should have thought of
undef.
By the way, I also found the way to clip the bottom of the gauge circle,
.......just put the canvas into a vbox......doh!!!.
my $vbox = Gtk2::VBox->new( FALSE, 6 );
$window->add($vbox);
$vbox->set_border_width(2);
my $canvas = Gnome2::Canvas->new_aa();
$canvas->set_size_request($width,$height);
$canvas->set_scroll_region( 0, 0, $width, $height ); #to get upper left
corner
$canvas->set_size_request( $width, $height ); #useless ?
$vbox->pack_start($canvas,FALSE,FALSE,0);
$window->show_all;
Thanks again.
