A Tkinter GUI slider element that slides along user-defined intervals, rather than being limited to linear intervals as in the default slider element. Used in the refresh rate slider in the control panel.
This class inherits from tkinter.Frame and will contain all the methods and properties of that class as well. These are not listed here.
Note that this is a Tkinter widget and thus will not work in other frontends like Jupyter notebooks. The recommended way to draw a log slider is with the higher-level Params.add() instead, setting the type parameter to 'slider' and the opts parameter to a list of ints.
WARNING: This is an internal class. Its use in user code is not recommended or supported, and its signature can change in future updates without warning. Use one of the suggested functions above instead, if applicable.
