Preventing overwrite mode in GtkEntry

["Nickolai Dobrynin" <ndobrynin gmail com>]

I was wondering if there is a way to make it so that the text that gets
typed into
the GtkEntry widget is always *inserted* into it and never replaces whatever
was previously
entered.  In other words, is it possible to suppress the "Insert" key so
that the overwrite mode
could never be entered into for that particular GtkEntry widget?


Many thanks,
