    Class GradumIconSwitch<State, ViewType, DataType, ModelType, EmitterType>

    Type Parameters

    Hierarchy (View Summary)

    Index
    customLoaders: Record<string, (path: string) => Element | Promise<Element>> = {}

    Extra icon loaders, keyed by file extension. Register one to teach every icon how to load a format the built-in SVG and image loaders do not cover.

    defaultProperties: Partial<GradumIconProperties> = ...

    Default properties assigned to a new icon. Icons are treated as SVG unless told otherwise.

    onLoaded: (element: Element) => void

    Called with the loaded element once the icon finishes loading. Loading is asynchronous for SVGs, so use this rather than reading the element straight after assigning an icon name.

    type: string

    The type of the icon.

    directory: string

    The user-provided (or statically configured) directory to the icon's file.

    onAttach: Delegate<() => void> = ...

    Delegate fired when the element is attached to DOM.

    onDetach: Delegate<() => void> = ...

    Delegate fired when the element is detached from the DOM.

    onAdopt: Delegate<() => void> = ...

    Delegate fired when the element is adopted by a new parent in the DOM.

    tagName: string
    initialized: boolean

    Whether the element was initialized already or not.

    defaultFeedforwardProperties: GradumElementProperties

    The properties passed on to children created through feedforward, letting a parent seed its descendants with shared defaults.

    view: ViewType

    The view (if any) of the element.

    model: ModelType

    The model (if any) of the element.

    emitter: GradumEmitter

    The emitter (if any) of the element.

    data: DataType

    The main data block (if any) attached to the element, taken from its model (if any).

    dataId: string

    The ID of the main data block (if any) of the element, taken from its model (if any).

    dataIndex: number

    The numerical index of the main data block (if any) of the element, taken from its model (if any).

    dataSize: number

    The size (number) of the main data block (if any) of the element, taken from its model (if any).

        GradumModel<any, any, any, any, any>,
        GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
    >[]

    The operators (if any) attached to the element's MVC structure.

    handlers: GradumHandler<GradumModel<any, any, any, any, any>>[]

    The handlers (if any) attached to the element's model. Returns an empty array if no model is set.

    interactors: GradumInteractor<
        object,
        GradumView<
            any,
            any,
            GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,

        GradumModel<any, any, any, any, any>,
        GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
    >[]

    The interactors (if any) attached to the element's MVC structure.

    tools: GradumTool<
        object,
        GradumView<
            any,
            any,
            GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
        >,
        GradumModel<any, any, any, any, any>,
        GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
    >[]

    The tools (if any) attached to the element's MVC structure.

    >[]

    The constrainers (if any) attached to the element's MVC structure.

    unsetDefaultClasses: boolean

    Whether to set the default CSS classes defined in the static config on the element or not. Setting it will accordingly add/remove the CSS classes from the element.

    shadowDOM: boolean

    Whether the element renders its children into a shadow root. Assigning true attaches one if the element does not already have it.

    defaultClasses: string | string[]

    The CSS classes applied to every instance of this element class. Assigning a new value swaps the previous classes out for the new ones, unless unsetDefaultClasses is set.

        The path to the SVG file.

      Returns Promise<SVGElement>

      The loaded SVG element.

      Fetch an SVG file and return its root element. Results are cached, so the same path is only fetched once.

      loadImg

      Parameters

      • path: string

        The path to the image file.

      Returns HTMLImageElement

      updateColor

      Parameters

      • Optionalvalue: Color = ...

        The color to apply. Defaults to the icon's own color.

      Returns void

      Recolor the icon by setting its fill. Only applies to SVG icons; raster images are left as they are.

    • Protected Function

      generateIcon

      Returns void

      Load the icon for the current name and type, and swap it in as this element's content. Reuses the existing element when only the source changed.

    • Function

      initialize

      Returns void

      Set the icon up and apply its default state.

            defaultSelectedClasses?: string | string[];
            defaultClasses?: string | string[];
        }

        Properties to set on the new instance.

      Returns This["prototype"] & GradumElement<ViewType, DataType, ModelType, EmitterType>

      The created instance, typed as the class this was called on.

      Instantiate this class with the given properties. Defaults declared by every class in the inheritance chain are applied first, nearest ancestor last, so a subclass' defaultProperties win over its parent's. The return type follows the class it is called on, and the MVC type parameters are read back off the properties — passing model: MyModel types .model as MyModel without a cast.

      Note: the callee is read through this["prototype"] rather than InstanceType<this>, because the latter instantiates a generic class' parameters with their constraints instead of their defaults, which is what forced casts at call sites.

    • Protected Function

      Parameters

      • properties: object

        Properties to set on the new instance, defaults already merged in.

      Returns object

      The created instance.

      customCreate

      The construction step behind create. Override it to change how instances of a class are built — to route through a factory, or to wrap the instance — while keeping the default-merging that create performs.

    • Protected Function

      setupChangedCallbacks

      Returns void

      Setup method intended to initialize change listeners and callbacks. Called on initialize().

    • Protected Function

      setupUIElements

      Returns void

      Setup method intended to initialize all direct sub-elements attached to this element, and store them in fields. Called on initialize().

    • Protected Function

      setupUILayout

      Returns void

      Setup method to create the layout structure of the element by adding all created sub-elements to this element's child tree. Called on initialize().

    • Protected Function

      setupUIListeners

      Returns void

      Setup method to initialize and define all input/DOM event listeners of the element. Called on initialize().

    • Function

      Returns void

      function called when the element is adopted by a new parent in the DOM.

    • Function

      destroy

      Returns this

      Itself, allowing for method chaining.

      Destroys the node by removing it from the document and removing all its bound listeners.

    • Function

      feedforward

      Parameters

      • Optionalproperties: FeedforwardProperties

        Properties to feed forward. Defaults to defaultFeedforwardProperties.

      Returns this

      Itself, allowing for method chaining.

      Push this element's feedforward properties down to its children, so newly added descendants pick up the same defaults.

    • Function

      clone

      Parameters

      Returns this

      The cloned element.

      Create a copy of this element. By default the copy carries the same properties and children but none of the bound listeners.
