tkinter canvas

[Gigs_]

I want to when create text box with

objid = self.canvas.create_text(x, y, width=event.x-x, text='')
how can i bind KeyPress to objid?

I want that text appear on canvas as i write it.
dont know do I need to use self.canvas.create_window, and put in that window 
Tkinter Text widget.
Or I can do it with canvas.create_text.


thanks!
