Basalt/docs/objects/Menubar.md

Menubars are like lists but instead of being vertical, they are horizontal. Imagine you are creating a Operating System and you would like to add a taskbar, menubars would be exactly what you need, because they are also scrollable, which means they have endless entry possibility.

If you want to access values inside items this is how the table for single items is made (just a example):

item = {
  text="1. Entry", 
  bgCol=colors.black, 
  fgCol=colors.white
  args = {}
}

Here are all possible functions available for menubars. Remember menubar inherits from Object

addItem

Adds a item into the menubar

Parameters:

1. string The entry name
2. number|color unique default background color
3. number|color unique default text color
4. any any value - you could access this later in a :onChange() event (you need to use :getValue()).

Returns:

1. object The object in use

Usage:

• Creates a default menubar with 3 entries

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aMenubar = mainFrame:addMenubar("myFirstMenubar"):show()
aMenubar:addItem("1. Entry")
aMenubar:addItem("2. Entry",colors.yellow)
aMenubar:addItem("3. Entry",colors.yellow,colors.green)
