How to write a webkit application where a javascript will invoke a QT C++ methods?

shreyas

I am writing a QT application - console one on the QT creator on FC19 machine. The aim here is to call a QT method from a javascript.

At the moment, I am following this link -

http://qt.developpez.com/doc/4.7/qtwebkit-bridge/

I am facing two problems -

First compilation -

/home/joshis1/Demo_JS/main.cpp:2: error: QWebElement: No such file or directory
#include <QWebElement>

#include <QCoreApplication>
#include <QWebElement>

class MyObject : QObject {
Q_OBJECT

public slots:
    void doSomethingWithWebElement(const QWebElement&);
};

/* ... */

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

MyObject myObject;
myWebPage.mainFrame()->addToJavaScriptWindowObject("myObject", &myObject);


return a.exec&#40;&#41;;

}

Here is the pro file -

#-------------------------------------------------

Project created by QtCreator 2014-02-08T17:31:01

#-------------------------------------------------

QT += core

QT -= gui

TARGET = Demo_JS
CONFIG += console
CONFIG -= app_bundle
QT += webkit

TEMPLATE = app

SOURCES += main.cpp

The next upcoming challenge I thinks is how to relate a javascript present in any folder of my FC19 to invoke a QT function defined in the above program. How my javascript will know the path to pick the application. How it can be done? This is my javascript wrapped in a html file.

<html>
<head>
[removed]
function runExample() {
myObject.doSomethingWithWebElement(document.getElementById("someElement"));
}
[removed]
</head>
<body >
<span id="someElement">Text</span>
</body>
</html>

Please help me here with an elaborate explanation. I am literally frustrated with all my trials.
