Hey guys I am trying to change the color of the text for the slider/click line response option but I can not find it. I have tried the following in the coding option:
color='black'
But no success, help!
In order to set the color property of an object, you need to refer to that object, otherwise you’re just creating a variable called color which isn’t linked to anything! If we were to call your slider mySlider, the code would look like this:
mySlider.color = 'black'
Thanks for the help. I get an odd error now, here’s what the error says:
## Running: C:\Users\micha\Desktop\school\RESEARCH_lastrun.py ##

Oh, I see, you meant when initialising the object. My mistake!
So the slider is an instance of a class called RatingScale - when you create it, you pass the class a load of information describing what kind of RatingScale you want to create. With these you supply labels, in this case color, and the class will have methods for storing that information in the property. Once the instance has been created, it will have the name you gave it, in this case rating and you can then change its color by using rating.color. That’s what I thought you were trying to do.
To change the color when creating it, the label you need to use for RatingScale is textColor. However, RatingScale is no longer under active support so I would recommend switching to the much more recent Slider component, which can do all the same things as Rating Scale and more! For that one you would use color.
