Re: GtkTextView: how to stop default "paste-clipboard" handler ?

["Miroslav Rajcic" <rajcic sokrates hr>]

There is also a context menu for text view that contains the "Copy"/"Paste" 
items.

Is there an alternative way? Is it not possible to prevent the default 
handler  for this ?

Regards,
 Miroslav
