        enabled: boolean;
        onClick: Function;
    }>
  • The structure of menu items

  • Return the CSS application ID which uniquely references this UI element

    Returns string

  • get element(): jQuery
  • Return the active application element, if it currently exists in the DOM

    Returns jQuery

  • get template(): string
  • The path to the HTML template file which should be used to render the inner content of the app

    Returns string

  • get popOut(): boolean
  • Control the rendering style of the application. If popOut is true, the application is rendered in its own wrapper window, otherwise only the inner app content is rendered

    Returns boolean

  • get rendered(): boolean
  • Return a flag for whether the Application instance is currently rendered

    Returns boolean

  • get closing(): boolean
  • Whether the Application is currently closing.

    Returns boolean

    Returns string

  • get defaultOptions(): object
  • Assign the default options configuration which is used by this Application class. The options and values defined in this object are merged with any provided option values which are passed to the constructor upon initialization. Application subclasses may include additional options which are specific to their usage.

Methods

  • An application should define the data object used to render its template. This function may either return an Object directly, or a Promise which resolves to an Object If undefined, the default implementation will return an empty object allowing only for rendering of static HTML

    Parameters

    • options: {} = {}

      Returns {
          items: Record<string, {
              label: string;
              icon: string;
              enabled: boolean;
              onClick: Function;
          }>;
      }

      • items: Record<string, {
            label: string;
            icon: string;
            enabled: boolean;
            onClick: Function;
        }>
    • After rendering, activate event listeners which provide interactivity for the Application. This is where user-defined Application subclasses should attach their event-handling logic.

      Parameters

      • html: any

      Returns void

    • Toggle display of the menu (or render it in the first place)
