I'd been reading that when I constructed it originally. I've also tried
another method, as posted to the list. Neither worked...

Here's what I've got going. I'm pulling data from an XML file using
XML::DOM. To ensure that I'm getting integers to pass to
Gtk2::SpinButton's max and min values, I'm using something like:

    my $min = int($node->getAttribute('min'));
    my $max = int($node->getAttribute('max'));
    my $val = $option->{int_value}; # this is already an integer
    my $step = $node->getAttribute('step');

    ($step) ? $step = int($step) : $step = 1;

    my $spin = Gtk2:SpinButton->new_with_range($min, $max, $step);
    $spin->set_value($val);
 
And that's not working. I've even setup some print statements to make
sure that it's getting proper values (it is), but the value isn't being
set.

Oddly enough, if I set the value *later*, i.e. after it's been
manipulated, it *will* take. Go figure.

Any ideas?

(I should probably upgrade to 0.92 to see if the error still happens
there... I'm on 0.90 -- unless no changes have been made to this
portion...)
