[Interest] QML WebView modules

[Nibedit Dey]

Dear Sze-Howe,

I haven't worked much in Qt web modules. But below is my understanding.

With Qt 5.5 the Qt WebKit module is deprecated:(
https://wiki.qt.io/New-Features-in-Qt-5.5#Deprecated_Functionality)

QWebView uses WebKit as the backend.

QWebEngineView uses Chromium as the backend.

WebView with the *same name* has been defined in both *WebKit* and
*WebEngine*. Hence import statement varies.[I believe this is the source of
confusion ]

*import QtWebKit 3.0*
*import QtWebView 1.0*

In 5.8,
*import QtWebView 1.1*
QT += qml quick *webview*
This is useful on mobile platforms such as Android, iOS, and WinRT;
especially on iOS, where policy dictates that all web content is displayed
using the operating system's web view. [
http://doc.qt.io/qt-5/qtwebview-index.html ]

Regards,
Nibedit
