Define tick positions for viz.SLIDER

[hotshotiguana]

Is there a way to define precise tick positions for a viz.SLIDER GUI element? For example, I want to only let someone move the slider to defined points along a linear space - numpy.linspace(0, 1, 26) - so I can easily get the index for the where the tick is located.

Any assistance is greatly appreciated.

Within the slider callback you can compute the nearest defined point and move the tick to it. Example:

import viz
import vizact
viz.go()

slider = viz.addSlider(pos=(0.5,0.1,0))

SLIDER_STEPS = 10

def UpdateSlider(pos):
	val = round(SLIDER_STEPS*pos) / float(SLIDER_STEPS)
	slider.set(val)
vizact.onslider(slider,UpdateSlider)

Thanks. That works as advertised.
