Layout

A scripted Layout which can function just like a Node but also has the ability to fit into a layout box provided via resize. It can also be intrinsically sized allowing hosting layouts to attempt to fit to its size by using the measure function to report desired dimensions.

For more information, see Layout Scripts.

Methods

measure

measure(self: T) -> Vector

When provided this Layout can be intrinsically sized/request to be a specific size. This is not guaranteed as the layout may have min/max dimensions. Resize will be called with the granted size after being measured.

-- Measure the computed size of the layout on resize
function measure(self: MyLayout): Vector
  return Vector.xy(100, 100)
end

resize

resize(self: T, size: Vector) -> ()

When provided, called to set the initial size and again whenever the size changes. Layouts that do not react to their box may omit it; the runtime no-ops when it is not implemented.

-- Called when the layout resizes based on the content
-- This only applies to Layouts with a fit type of Hug
function resize(self: MyLayout, size: Vector)
  print('Resize:', size)
end
