Widget GUI view

Displays a combination of custom elements on one screen.

let eventLoop = require("event_loop");
let gui = require("gui");
let widgetView = require("gui/widget");

This module depends on the gui module, which in turn depends on the event_loop module, so they must be imported in this order. It is also recommended to conceptualize these modules first before using this one.

Example

For an example, refer to the gui.js example script.
