Signal Handler Block

["Vladimir V. Markevich" <markj LinS ospu odessa ua>]

Hi All.

How to I can temporary block handler in signal handler function?
In the Gtk-Perl tutorial I find some function 

     $widget->signal_handler_block( $callback_id);
     $widget->signal_handler_block_by_func( \&callback, $data );
     $widget->signal_handler_block_by_data( $data );

but I can't recorded callback id in some variable, because I use Glade
Perl and do not connect signal handler by hand. 
About a two lower function, I can't use it, Perl say undefained method,

How I can get signal id with Glade Perl or how I can block signal hadler 
without signal id.

Thank you, anyway.
