    Class GradumMovable<ContentType>

    GradumMovable

    Positioning wrapper that places arbitrary content via pure CSS transforms. Set translation (alias position) and rotation to move/rotate the wrapper without touching the content's own fields — useful for previews (feedforwards), ghosts, overlays, or any element that must be positioned independently of how its content renders itself.

    const movable = GradumMovable.create({content: myElement});
    movable.translation = new Point(120, 40);
    movable.rotation = Math.PI / 6;
    movable.translateBy(new Point(5, 0));

    rotation: number = 0

    centerAnchor: boolean = false

    When true, the wrapper is offset by -50% so translation refers to its center.

    defaultProperties: GradumElementProperties = ...

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

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

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

    >[]

    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.

    content

    • set content(value: ContentType): void

      Parameters

      Returns void

      The content element wrapped by this movable. Assigning it appends it as a child.

    • get position(): Point

      Returns Point

      Alias of translation, so code that positions elements through a position field (e.g. constrainer solvers) works on the wrapper as-is.

    • set position(value: Point | Coordinate): void

      Parameters

      Returns void

    • 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().

    • Returns void

    • Parameters

      Returns void

      Add the given delta to the current translation.

    • Parameters

      • angle: number

      Returns void

      Add the given angle (radians) to the current rotation.

    • Function

      create

      Type Parameters

      Parameters

      • this: This
      • Optionalproperties: This["prototype"]["properties"] & ElementTagDefinition<"div"> & Omit<
            HTMLElementMutableFields<"div">,
            "tag" | "namespace",
        > & {
            id?: string;

            text?: string;
            listeners?: Record<
                string,
                (e: Event, el: ValidElement<Tag>) => boolean | any,
            >;
            onClick?: (e: Event, el: HTMLDivElement) => any;
            onDrag?: (e: Event, el: HTMLDivElement) => any;
            out?: string | Node;
            [key: string]: any;
        } & MvcProperties<ViewType, ModelType, EmitterType> & {
            data?: DataType;
            initialize?: boolean;
        } & { out?: string
        | Node; [key: string]: any } & {
            unsetDefaultClasses?: boolean;
            shadowDOM?: boolean;
            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

      setupUIListeners

      Returns void

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

    • Function

      connectedCallback

      Returns void

      function called when the element is attached to the DOM.

    • Function

      disconnectedCallback

      Returns void

      function called when the element is detached from the DOM.

    • Function

      adoptedCallback

      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

      initialize

      Returns void

      Initializes the element. It sets up the UI by calling the methods setupUIElements, setupUILayout, setupUIListeners, and setupChangedCallbacks (in this order, if they are defined). This function is called automatically in .setProperties() and when instantiating an element via element(). It is called only once per element (as it checks with the reflected initialized flag).

    • 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.
