I am using Perl binding of GTK GooCanvas (Perl Goo::Canvas module).

I want to move a canvas item (say rectangle for e.g.) using keyboard keys (arrow keys specially). First, when user presses, F8 key, canvas item, gets focus, and user can move it using arrow keys. User presses, F8 once again, canvas item, which was already in focus, move out of focus, and gets positioned at new position.

Also, I am not able to write a single sub, for handling canvas item's event routine. If I write, following: 

$item->signal_connect ('event' => \&event_handler);
$item->signal_connect (event => \&event_handler);

I receive invalid instance, error message for above line.
