(Tkinter) Can I bind a key to Canvas?

[Davy]

Hi all,

I have a canvas and a rectangle draw on it. Can I bind a key(e.g. UP)
to the canvas and make the rectangle move up? Or shall I bind the key
to rectangle(I don't think so, because it is not a widget)?

Any suggestions are welcome!
Best regards,
Davy

I have tried key and mouse click (when receive a event, print some
diagnose information ). I found mouse click work well in canvas but
key not work well.

It seems canvas cannot get key event?

self.canv.bind('<Up>',self._onUpKey) ## don't work
self.canv.bind('<Button-1>', self._onClick) ## work

Any suggestion?

Best regards,
Davy
