Please, how can I wrap and unwrap the 'wrap' attribute of the Text Widget by toggle with the check button (Word Wrap) in the sub-menu of my Menu Widget. Once it's checked the xscrolledbar (horizontal) should hide with the attribute 'wrap' set to WORD and once unchecked the xscrolledbar should show/display with wrap attribute set to NONE.
Thanks.

You're really close- I made some changes to your callback:

    def wrap_text(self):
        self.use  = self.wrap.get()        
        if self.use:
            self.text.config(wrap=WORD)
            self.wrap.set(0)            
            
        else:
            self.text.config(wrap=NONE)           
            self.wrap.set(1)

Thank you very much for your reply.
But is there a way I can also toggle (show/display) with tkinter x-scrollbar (Horizontal) on click of the 'Word wrap' submenu.
Thanks again.

there may be other ways to accomplish this but .pack_forget() works:

def wrap_text(self):
        self.use  = self.wrap.get()        
        if self.use:
            self.text.config(wrap=WORD)
            self.scrollbar_2.pack_forget()
            self.wrap.set(0)            
            
        else:
            self.text.config(wrap=NONE)
            self.scrollbar_2.pack(fill=X, expand=NO)
            self.wrap.set(1)
