[Matplotlib-users] Possible bug in <slider>.reset() ?

[peterfR <pe...@pe...>]

[This post might appear twice, if so, I apologize. The first version is
flagged that it has not been accepted yet]

I am controlling a simple animation with a slider, successfully. A mouse
drag updates the parameter correctly but the slider-bar position is not
updated.

If "samp" is a slider, the code
"samp.reset(amp)" generates
"TypeError: reset() takes exactly 1 argument (2 given)".

Here is more detail of the code:

=====
samp = Slider(axamp, 'Amp', 0.1, 10.0, valinit=amp)

def update(val):
    global amp
    amp = samp.val
#   samp.reset()        # if this is included, a mouse-drag does not change
value of amp. No error.
#   samp.reset(amp)  # if this is included, a mouse-drag changes value of
amp, but the
                     # slider-bar-position is not updated. The animation
continues to run in both cases.
                     # AND GET ERROR:  
***********
 File "SAS_asl.py", line 28, in update
    samp.reset(amp)     #

TypeError: reset() takes exactly 1 argument (2 given)
***********
 

# If there is no call to reset in “update” and the following function is
included:

def reset(event):
    samp.reset()     # amp is changed, slider-bar-position is not updated
and NO ERROR IS GENERATED


samp.on_changed(update)  # always present!

This appears to be a bug. If not, what is wrong with the code?
