Using OptionProperties and Spinners

[Yoel Koenka]

In my app I'm using a Spinner.

It seemed to me like a good idea to back it up from the Python side with an OptionProperty, and use it to initialize the Spinner:

<DigitalVariable>:
    Spinner:
        text: root.value
        values: root.value.options

class DigitalVariable(Variable):
    '''A digital variable
    '''

    value = OptionProperty('???', options=['???'])
    '''The current value with its possible options
    '''

root.value is an OptionProperty (created in the python code), so I thought I could get its options by using root.value.options. But that doesn't work.
Is there another way to access the options?

Is there a better way of using Spinners that I'm missing?

You could just use a ListProperty.

Thanks for the advice, I'll do that.

If someone is looking for the answer, here's how to use Spinner and OptionProperty. We need to get the property object first, and then we can easily bind Spinner's values with OptionProperty options.

Spinner:

    values: widget,property('option_property_name').options

The widget reference is of course widget that has the OptionProperty we want to use.

Cheers!
