Hi,

You need to know the 'connection id' of the signal_connect call that
is triggering the handler. The connection id is returned by the
signal_connect() call so you do:

  $id = $widget->signal_connect('changed', ......

and later:
  
  $widget->signal_handler_block($id); 

$id probably needs to be a global so that it is available in the handler.

Version 0.60 of Glade-Perl can generate code that saves the ids in a
predictable fashion so that you can use them in signal handlers like:

  my $id = $form->{'__CONNECT_ID'}{'entry1'}{'after_key_press_event'}
  $id = $widget->signal_connect('changed', ......
  ...

HTH, Dermot
