Scrollbar

Scrollbars are objects, the user can scroll vertically or horizontally, this can change the value.
Here is a example of how to create a standard scrollbar:

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aScrollbar = mainFrame:addScrollbar("myFirstScrollbar"):show()

Here are all possible functions available for scrollbars. Remember scrollbar inherit from object:

setSymbol

Changes the symbol

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aScrollbar = mainFrame:addScrollbar("myFirstScrollbar"):setSymbol("X"):show()

parameters: char symbol
returns: self

setBackgroundSymbol

Changes the background symbol color

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aScrollbar = mainFrame:addScrollbar("myFirstScrollbar"):setSymbol("X"):setBackgroundSymbol(colors.green):show()

parameters: number symbolcolor
returns: self

setBarType

If the bar goes vertically or horizontally

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aScrollbar = mainFrame:addScrollbar("myFirstScrollbar"):setBarType("horizontal"):show()

parameters: string value ("vertical" or "horizontal")
returns: self

setMaxValue

the default max value is always the width (if horizontal) or height (if vertical), if you change the max value the bar will always calculate the value based on its width or height - example: you set the max value to 100, the height is 10 and it is a vertical bar, this means if the bar is on top, the value is 10, if the bar goes one below, it is 20 and so on.

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aScrollbar = mainFrame:addScrollbar("myFirstScrollbar"):setMaxValue(123):show()

parameters: any number
returns: self
