Ok, I finally made it work with a ToggleButton. First, lets say that I use 
the 'pressed' and 'released' events, the first to start a motor move, the 
second to stop the motor move. I do no need the 'clicked' event.

Here is what I did:

1) I binded the 'pressed' and 'released' events of the toggle button.

2) I binded the 'pressed' and 'released' events of the associated key.
