Adjusting table scroll bar width

[runrc]

The scrollbar on the right side of the table is very small/thin.
How can I make the scrollbar width bigger?

Are you referring to the scrollbar width or handle height? The handle height of the scrollbar is based on the amount of content with a lower bound, but we could increase that minimum value, which would increase the scrollbar handle height. You can change the width of the scrollbar for a single table with this code (I will change this to be easier now by making the value inherited):

	tree.AddChildInit(tb, "grid", func(w *core.ListGrid) {
		w.Styler(func(s *styles.Style) {
			s.ScrollBarWidth.Dp(50) // or any other value
		})
	})

Or for all scrollbars with this code:

	styles.ScrollBarWidthDefault = 50 // or any other value

Yes, thank you I was referring to the width of the scroll bar. This resolves the issue, although it might be worthwhile adding this to the Styling section of the documentation.

OK. In answering this I realized that this structure could be improved, so after #1132 is merged, it will be this instead:

For a single table/frame/widget and all of its children:

	tb.Styler(func(s *styles.Style) {
		s.ScrollbarWidth.Dp(50)
	})

For all scrollbars:

	styles.DefaultScrollbarWidth.Dp(50)

Apologies for the change.

That's great, it's not a problem at all. It's important these things are ironed out and documented. Thanks!

OK, I also improved the styling documentation in 7aef318 with a link to a list of all styling properties, including the scrollbar width, which now also has struct field documentation mentioning DefaultScrollbarWidth.
