Create a dialog window displaying a title, a message, and a set of buttons which trigger callback functions.

Param: data

An object of dialog data which configures how the modal window is rendered

Param: options

Dialog rendering options, see Application.

Example: Constructing a custom dialog instance

let d = new Dialog({
title: "Test Dialog",
content: "<p>You must choose either Option 1, or Option 2</p>",
buttons: {
one: {
icon: '<i class="fas fa-check"></i>',
label: "Option One",
callback: () => console.log("Chose One")
},
two: {
icon: '<i class="fas fa-times"></i>',
label: "Option Two",
callback: () => console.log("Chose Two")
}
},
default: "two",
render: html => console.log("Register interactivity in the rendered dialog"),
close: html => console.log("This always is logged no matter which option is chosen")
});
d.render(true);

See

#onKeyDown: ((arg0) => any)

A bound instance of the _onKeyDown method which is used to listen to keypress events while the Dialog is active.

Type declaration

    • (arg0): any
    • Parameters

      • arg0: KeyboardEvent

      Returns any

RENDER_STATES: Readonly<{
    ERROR: -3;
    CLOSING: -2;
    CLOSED: -1;
    NONE: 0;
    RENDERING: 1;
    RENDERED: 2;
}> = ...

The sequence of rendering states that track the Application life-cycle.

Type declaration

  • ERROR: -3
  • CLOSING: -2
  • CLOSED: -1
  • NONE: 0
  • RENDERING: 1
  • RENDERED: 2

Accessors

  • get title(): any
  • An Application window should define its own title definition logic which may be dynamic depending on its data

    Returns any

  • get id(): string
  • 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

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 {
          content: any;
          buttons: {};
      }

      • content: any
      • buttons: {}
      • 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

      • Render the outer application wrapper

        Returns Promise<jQuery>

        A promise resolving to the constructed jQuery object

      • Close the application and un-register references to it within UI mappings This function returns a Promise which resolves once the window closing animation concludes

        Parameters

        • options: {} = {}

          Options which affect how the Application is closed

          Returns Promise<void>

          A Promise which resolves once the application is closed

          Fires

          closeApplication

        • Render the Application by evaluating it's HTML template against the object of data provided by the getData method If the Application is rendered as a pop-out window, wrap the contained HTML in an outer frame with window controls

          Parameters

          • force: boolean = false

            Add the rendered application to the DOM if it is not already present. If false, the Application will only be re-rendered if it is already present.

          • options: {
                left: number;
                top: number;
