Slider Assistance

Hi All,

I'm currently working on incorporating a slider into my work.

A few questions...

1) Is there a way of labelling different areas of the slider for the user? I have already specified the different intervals in the code.

2) Is there a way of outputing the slider value from the code? So in trial 1 for instance, where did the user move the slider to when prompted.

Thanks

1) Do you want labels above or below the slider? If so, you can create text objects and position them at those intervals.

2)Register a callback function for the slider event using vizact.onslider:
Code:
import viz
viz.go()

slider = viz.addSlider(pos=[0.5,0.5,0])
def sliderChanged( pos ):
    print pos
vizact.onslider( slider, sliderChanged )

Hi Jeff,

Thanks for your prompt response.

I have been trying this method and it does not seem to allow me to register the slider position as a variable for an output.

How can I assign the "pos" value to a variable? For instance, "slidepos"?

Thanks

I'm not sure I understand the question. Can you post some example code that shows what you are trying to do?
