Accessing ActionButton1 objects

local button = ActionButton1
local buttonName = button:GetName()
 
local icon = _G[buttonName.."Icon"]
local flash = _G[buttonName.."Flash"]
local flyoutBorder = _G[buttonName.."FlyoutBorder"]
local flyoutBorderShadow = _G[buttonName.."FlyoutBorderShadow"]
local flyoutArrow = _G[buttonName.."FlyoutArrow"]
local hotKey = _G[buttonName.."HotKey"]
local count = _G[buttonName.."Count"]
local name = _G[buttonName.."Name"]
local border = _G[buttonName.."Border"]
local NewActionTexture = button.NewActionTexture
local cooldown = _G[buttonName.."Cooldown"]
 
local normalTexture = button:GetNormalTexture()
local pushedTexture = button:GetPushedTexture()
local highlightTexture = button:GetHighlightTexture()
local checkedTexture = button:GetCheckedTexture()

All actionbars (minus ExtraActionBar) use ActionButtonTemplate for default button styles.

Notable differences:

PetActionBar has 3 new objects

• AutoCastable
• Shine
• NormalTexture2 (overrides NormalTexture from the ActionButtonTemplate, but retrievable by using button:GetNormalTexture().)

StanceBar has one new object

• NormalTexture2 (overrides NormalTexture from the ActionButtonTemplate, but retrievable by using button:GetNormalTexture().)

ExtraActionBar
ExtraActionButton1 has its own template and thus needs a different style function.
ExtraActionButton1.style is the wierd art around the ExtraActionButton1.
ExtraActionButton1 has two Textures with $parentname = "Flash". Not sure if that is a bug.
