Which properies of scroll-pane and progressbar can be changed in runtime (in control.lua)?
Where can I see the full list of its properties?

While not specific to those element types, it will error if it can't accept the style, so just trial and error them

Thanks for the reply.
As I know, smooth_color and other_smooth_colors are specific for a progressbar, but using it in a script causes "doesn't contain key" error, so I have to define styles. Is it correct?

Those progress bar color properties only exist in the prototypes (data.lua), not in the exposed GUI element objects you see in the game (control.lua).

As far as I know, only the properties listed here and here are available from control.lua, and some of them are specific to certain types of GUI element.

Regarding scroll-panes do you know if it would be possible for us to set a value on a scrollbar? Would be helpful when you want a default value of at the bottom instead of at the top.

It's not possible, although there was some discussion a while back about adding ability to determine if an element is visible within a scroll panel, and also a method to make a panel scroll to show a specified element. Not sure if that's going to happen though.
