Slider and progress bar in one custom widget (looking for detailed information / detailed description)

Hello, I am looking for detailed information / detailed description for
slider and to progress bar,

Would like to create a custom widget (which is basically already running very well) but still want to implement some important requirements.

that’s why I’m looking for:
a list and meaning of the “parameters” as well
the possibility to change the display direction. (vertical, horizontal)

A slider doesn’t work vertically in my custom widget. and a Progress-bar you have to work with (rotate (-90deg)) which makes things rather confusing.

Would like to display the value with decimal places but the markings should have a resolution of 5. (step; precision)?

Which user interface?

I am looking at the moment for a solution in HABPANEL
