  • 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

    Returns boolean

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

  • get defaultOptions(): object
  • Assign the default options which are supported by the document edit sheet. In addition to the default options object supported by the parent Application class, the Form Application supports the following additional keys and values:

    Returns object

    The default options for this FormApplication class

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 {
          fonts: object[];
          selected: any;
          font: any;
          family: string;
          weights: {
              value: number;
              label: string;
          }[];
          styles: {
              value: string;
