1.164.1 Class variables

scroll_bar.arrows: bool = @off

If @on, the scroll_bar has a line up/down (left/right) arrow at each end. Pressing an arrow scrolls one line, repeating while it is held. Without arrows, scrolling by line is left to the mouse wheel and the keyboard.

scroll_bar.background: [elevation|colour] = ui_scrollbar_background

Colour of the trough. For compatibility, the colour of an elevation is used.

scroll_bar.thumb_colour: [colour] = @default

Colour of the thumb, the rounded bar that shows the part of the object that is visible. @default uses a clearly visible variation of the background: darker for a light and lighter for a dark one. The thumb is wider while the pointer is in the scroll_bar.

scroll_bar.pressed_colour: colour = ui_button_pressed

Background of a pressed arrow.

scroll_bar.repeat_interval: num = 0.06

If the scroll_bar object has a UI for repeated scrolling, this class-variable determines the speed. See also scroll_bar.repeat_delay.
