    global x,y,dx,dy
    x+=dx
    y+=dy
    #drawing.clear()
    drawing.rectangle(x, y, x+10, y+10, color="blue")
def do_this(event_data):
    print("key pressed : "+ event_data.key)
app = App()
drawing = Drawing(app,height=300, width=300)
drawing.bg="grey"
drawing.repeat(20,do_animation)
app.when_key_pressed = do_this
app.display()
