Pract.Children
All of the basic Element Creator functions take in an optional children argument, which will mount the child elements on their parent element’s created or decorated instance.
It is also possible to provide a children argument to components when we create them—however, we need to explicitly handle children props in order to do so! To do so, we can access the Pract.Children key in our passed-in props:
local function FancyList(props: {[any]: any, heading: string]})
-- Get our children passed in through props (note that this can be nil!)
local passedInChildren = props[Pract.Children] or {}
return Pract.stamp(script.ListTemplate, {}, {
-- Decorate a "Heading" label in our template
Heading = Pract.decorate({
Text = props.heading,
}),
-- Dump our passed-in children into a frame named "List", inside our stamped template
List = Pract.index(passedInChildren)
})
end
local function App(props: {})
return Pract.create(FancyList, {
heading = 'List of Things'
}, { -- These are assigned to the [Pract.Children] key of our props:
[1] = Pract.create('TextLabel', {
Text = 'Apples',
}),
[2] = Pract.create('TextLabel', {
Text = 'Builderman is my dad',
}),
})
end
See the API Docs for a more technical documentation of the Pract.Children symbol.
