Functional explanation
SliderObject is a linear analog control for numeric variables. It is commonly used for percentages, analog outputs, and simple setpoint adjustments.
The control gives the operator a visible scale and is useful when relative position matters as much as the exact number. It is a practical choice for controls that should be easy to move and easy to read.
Keep enough width so small adjustments remain practical and the feedback text stays readable.
