How can I use a Gtk2::SpinButton to prompt for an integer expressed in hex?  I've tried the following, but 
it fails.

   use strict;

   use Glib qw(TRUE FALSE);
   use Gtk2 qw(-init);

   $spin->signal_connect(output => \&outputCB);

   my($win)=new Gtk2::Window();


   sub outputCB
      my($spin)= _;

      $spin->set_text(sprint '%X',$value);

The text appears to be correct while I hold either arrow button down; I see hex values incrementing.  
However, single clicks of an arrow button fail if the displayed text contains A-F.  Hitting the Enter key 
also fails on the same values.  In both cases, the text changes to a decimal integer.



Hi Jim

What do the '$value's look like in the outputCB (either in a
debugger or ...).

sprint - should be sprintf?

Maybe try set_value or set_digits rather than set_text?

How are any of these impacted by the set_numeric statement?
