Use JavaScript Promises from QML

[h00bs]

The latest release of V-Play 2.18.1 includes JavaScript Promises for usage in QML.

Here is an example of how to use promises, together with the new HttpRequest type, based on DuperAgent:

import VPlayApps 1.0
import QtQuick 2.0

App {
  Component.onCompleted: {
    var p1 = Promise.resolve(3);
    var p2 = 1337;
    var p3 = HttpRequest
    .get("http://httpbin.org/get")
    .then(function(resp) {
      return resp.body;
    });
    
    var p4 = Promise.all([p1, p2, p3]);
    
    p4.then(function(values) {
      console.log(values[0]); // 3
      console.log(values[1]); // 1337
      console.log(values[2]); // resp.body
    });
  }
}
