Pointer in Q_PROPERTY

Hello,

I have a problem accessing pointer property, defined as Q_PROPERTY, in JavaScript using QWebKit - here is a simple example:

Code:

---

// MyObject.h
class MyObject : public QObject {
    Q_OBJECT
 
public:
    Q_PROPERTY (QString* version READ getVersion)
 
    QString* getVersion();
 
    QString* version;
 
public slots:
    void populateJavaScriptWindowObject();    
};
 
// MyObject.cpp
MyObject::MyObject() {
    qRegisterMetaType<QString*>("QString*");
 
    version = new QString("1.0");
 
    connect(app->getWebView()->page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()), this, SLOT(populateJavaScriptWindowObject()));    
}
 
QString* MyObject::getVersion() {
    return version;
}
 
void MyObject::populateJavaScriptWindowObject() {
    app->getWebView()->page()->mainFrame()->addToJavaScriptWindowObject("my", this);
}

---

In JavaScript I should get following object:

Code:

---

my: {version: "1.0"}

---

but instead I get:

Code:

---

my: {version: ""}

---

I will be grateful for any help, thanks!

Regards,
Piotr

It's better to expose QString object here because it is a standard QtScript type and will it be automatically converted to JS string.
In this case qRegisterMetaType won't be needed.

Code:

---

QString language();
Q_PROPERTY(QString language READ language SCRIPTABLE true);

---

Code:

---

QString mLanguage;

---

Code:

---

QString MediaComponent::language()
{
    return mLanguage;
}

---

... And it won't create memory leaks.
