Class

Minimal class & property system for Basalt.

Methods

class.create(name, parent)

Creates a new Basalt class deriving from an optional parent class.

• name (string) Class name

• parent (table, optional) Parent class

• returns class (table)

class.property(c, propName, default, opts)

Defines a property on a class and generates :setX()/:getX() accessors. opts.visual (default true): marks the UI dirty when the value changes. opts.onChange(self, new, old): runs after the value is stored. opts.rawFunction: functions are stored as-is instead of being treated as dynamic values. opts.rawString: "{...}" strings are stored as-is instead of being compiled as reactive expressions (for user-entered text). opts.state: mirrors the property's truthiness to a named element state. opts.stateWhen(value, self): custom predicate for the mirrored state. opts.styleable=false: state styles cannot override this property.

• c (table) Target class
• propName (string) Property name
• default (any) Shared default value
• opts (table, optional) Property behavior options

class.combinedProperty(c, combinedName, propertyNames)

Defines a fluent setter plus effective/raw getters spanning multiple existing properties. The combination stores no value of its own.

class.combinedProperty(Element, "Position", { "x", "y" }) creates: element:setPosition(x, y) element:getPosition() -- effective/resolved values element:getRawPosition() -- authored/default values

• c (table) Target class
• combinedName (string) Public combined-property name
• propertyNames (string[]) Ordered component property names

class.event(c, eventName)

Declares an event on a class and generates its :onX(fn) registrar.

• c (table) Target class
• eventName (string) Event name
