Can I mix HTML5 Local application with C++?

dcbasso

Can I make an application with UI using HTML5, for localhost application, and make some stuff with C++.
I will need C++ to send/receive data from USB/SERIAL!
It's possible to do?

AcerExtensa

Sure, why not? But not in the same .html file :)
You can use websockets to call your binaries written in c++, or you can create server-side application which evaluates requests from browser and returns html5 as response.

Write more exact explanation about what you actually want...

AcerExtensa, I need to code a Fast UI and HTML I can make all UI's very fast, and another devs can maintain the code easily.
That's A reason to use HTML5!

C++, as I said, I will need to develop to capture data from USB/SERIAL, and this data will be treated and show in HTML5 local app. I'm trying to avoid use TOMCAT/Glassfish...

If I could do what I want using QT, HTML5, JavaScript, XML, XSLT, C++ on a local app will be good enough or me.

AcerExtensa

First of all: are you planing to code html file which will be when accessible over the network with browser, or you want one app which GUI is coded in HTML?

dcbasso

I want one app which GUI is coded in HTML!

AcerExtensa

When just use QtWebKit, load HTML file on app-start and create some objects "which will be available from javascript":http://qt-project.org/doc/qt-4.8/qwebframe.html#addToJavaScriptWindowObject

"Here":http://qt-project.org/doc/qt-4.8/qtwebkit-bridge.html is more info about the QtWebKit bridge

AcerExtensa, thank you very much. I will study the brigde!
But just another question... Can I use something like this:

main.qml:
@
// import QtQuick 1.0 // to target S60 5th Edition or Maemo 5
import QtQuick 1.1
import QtWebKit 1.0

Rectangle {
id: window
width: 800
height: 600

WebView {
    //url: "http://www.nokia.com"
    url: "html/index.html"
    x: 0
    y: 0
    smooth: false
    anchors {
        top: window.top
        bottom: window.bottom
        left: window.left
        right: window.right
    }
}

}
@

My project:
@
/Other files
/html
/index.html
@

dcbasso

I use this:

@
WebView {
url: Qt.resolvedUrl( "html/index.html" )
x: 0
y: 0
smooth: false
anchors {
top: window.top
bottom: window.bottom
left: window.left
right: window.right
}
}
@

Appers to work! It's correct?

Are you seriously doing a C++ application with a QML UI consisting of one WebView displaying a HTML5 UI?

I don't really like HTML for UIs in the first place, but if that is your requirement, then you can just use a (C++) QWebView directly.

dcbasso

It's not a requirement, but it's gonna be easier to me use HTML5!
QML is very very powerful, but I couldn't understand how to create an entry app using them!
I have try here to create something, but appears any errors and I see that will be not easy to learn!
Well, I will try a little bit more!

AcerExtensa

QML + QtWebKit + HTML5 UI will be very tricky, and you will need to do C++ coding anyway if you need USB/Serial access. So, just use pure Qt C++, subclass QWebView & QWebPage and you can do then anything you want through bridging.
