Changing the position of the slider during a loop

[JensBoelte]

Hello,

It seems that the Slider is still bugged when it comes to setting the Position-parameter. As soon as you set the Position-parameter to “set every repeat” from constant, the position will be set to [0,0], no matter what you want it to be. You can check this by looking at the compiled Python script.

set every repeat

slider = visual.Slider(win=win, name='slider',
    startValue=None, size=(1, .1), pos=[0,0], units=None,
    labels=[1,2,3,4,5], ticks=(1, 2, 3, 4, 5), granularity=1.0,
    style='rating', styleTweaks=(), opacity=None,
    labelColor='LightGray', markerColor='Red', lineColor='White', colorSpace='rgb',
    font='Open Sans', labelHeight=0.05,
    flip=False, ori=0.0, depth=-1, readOnly=False)

should be

slider = visual.Slider(win=win, name='slider',
    startValue=None, size=(1, .1), pos=(0, -.2), units=None,
    labels=[1,2,3,4,5], ticks=(1, 2, 3, 4, 5), granularity=1.0,
    style='rating', styleTweaks=(), opacity=None,
    labelColor='LightGray', markerColor='Red', lineColor='White', colorSpace='rgb',
    font='Open Sans', labelHeight=0.05,
    flip=False, ori=0.0, depth=-1, readOnly=False)

Bug report: Slider component position & clickability

OS (e.g. Win10): Mac OX 10.14.4 PsychoPy version (e.g. 1.84.x): 3.1.0 **Standard Standalone? YES I have identified 2 problems with the builder slider component, both when in use as radio buttons: a) when you set the stimPos to update on repeat (i.e. variable), this does not translate over to coder – the script does not represent this and simply has [0,0] pos in the original initialization, but then does not put in code before the trial runs. TextStims whose pos is similarly determined DO upd…

BF: Allow Slider to accept values each repeat

but according to this is issue is closed. So, it should work.

I’ve been using 2022.2.5, perhaps 2023.1.2 does a better job.
