    Class GradumLabelElement<ElementTag, ViewType, DataType, ModelType, EmitterType>

    GradumLabelElement

    A rich element with an HTML <label> attached to it. Setting GradumLabelElement.label to a non-empty string creates the label and puts it before the content; setting it to an empty value removes it again.

    Type Parameters

    • ElementTag extends ValidTag = any

      The tag of the main element in the rich element.

    • ViewType extends GradumView = GradumView<any, any>

      The element's view type, if initializing MVC.

    • DataType extends object = object

      The element's data type, if initializing MVC.

    • ModelType extends GradumModel<DataType> = GradumModel

      The element's model type, if initializing MVC.

    • EmitterType extends GradumEmitter = GradumEmitter

      The element's emitter type, if initializing MVC.

    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.

    • get label(): string

      Returns string

    • set label(value: string): void

      Parameters

      • value: string

      Returns void

      The label's text. Assigning a non-empty string creates the <label> and places it before the content; assigning an empty value removes it. The label is linked to the inner element's id, so clicking it focuses that element.

    • get element(): ValidElement<ElementTag>

      Returns ValidElement<ElementTag>

      The text element. Can be set to a new element by a simple assignment. Setting the value to a new string will update the text's textContent with the given string.

    • set element(
          value: ValidElement<ElementTag> | GradumProperties<ElementTag>,
      ): void

      Parameters

      Returns void

      The text element. Can be set to a new element by a simple assignment. Setting the value to a new string will update the text's textContent with the given string.

    • set leftCustomElements(value: Element | Element[]): void

      Parameters

      Returns void

      The custom element(s) on the left. Can be set to new element(s) by a simple assignment.

    • get leftIcon(): GradumIcon

      Returns GradumIcon

    • set leftIcon(
          value:
              | string
              | GradumIcon<
                  GradumView<
                      any,
                      any,
                      GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
                  >,
                  object,
                  GradumModel<any, any, any, any, any>,
                  GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
              >,
      ): void

      Parameters

      Returns void

      The left icon element. Can be set with a new icon by a simple assignment (the name/path of the icon, or a Gradum/HTML element).

    • get prefixEntry(): HTMLElement

      Returns HTMLElement

    • set prefixEntry(value: string | HTMLElement): void

      Parameters

      Returns void

      The element shown before the text. Assigning a string sets its text content; assigning an element replaces it outright.

    text

    • get text(): string

      Returns string

      The text element. Can be set to a new element by a simple assignment. Setting the value to a new string will update the text's textContent with the given string.

      Parameters

      • value: string

      Returns void

    • get suffixEntry(): HTMLElement

      Returns HTMLElement

    • set suffixEntry(value: string | HTMLElement): void

      Parameters

      Returns void

      The element shown after the text. Assigning a string sets its text content; assigning an element replaces it outright.

    • get rightIcon(): GradumIcon

      Returns GradumIcon

    • set rightIcon(
          value:
              | string
              | GradumIcon<
                  GradumView<
                      any,
                      any,
                      GradumEmitter<GradumModel<any, any, any, any, any>, KeyType>,
                  >,
                  object,
                  GradumModel<any, any, any, any, any>,

              >,
      ): void

      Parameters

      Returns void

    • set rightCustomElements(value: Element | Element[]): void

      Parameters

      Returns void

      The custom element(s) on the right. Can be set to new element(s) by a simple assignment.

      Type Parameters

      Parameters

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

            classes?: string | string[];
            style?: string;
            stylesheet?: string;
            shadowDOM?: boolean;
            parent?: Element;
            children?: Element | Element[];
            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

      setupChangedCallbacks

      Returns void

      Setup method intended to initialize change listeners and callbacks. 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.
