error: ‘QVariant::QVariant(void*)’ is private within this context

Hello,

Does someone would know what could be the problem ?

error: ‘QVariant::QVariant(void*)’ is private within this context

I'm trying simply to expose the class Tool to the QML file like that:

Code:

---

QDeclarativeView *view = new QDeclarativeView();
view->rootContext()->setContextProperty("Tool", new Tool);
view->setSource(QUrl("qrc:/qml/main.qml"));
view->show();

---

Any help would be appreciated

Cheers !

How is 'Tool' defined?
On which line of the given code is the compile error you get?

Tool class definition:

Code:

---

#ifndef TOOL_H
#define TOOL_H
 
#include <QObject>
 
#include <tool.h>
 
 
class Tool
{
//     Q_OBJECT
 
public:
    Tool();
    Q_INVOKABLE QList<Type*>getStorage();
 
private:
    QList<Type*> typeList;
};
 
#endif // TOOL_H

---

The compiling error occurs at line 9:

view->rootContext()->setContextProperty("UReceivedMessage", new Tool);

Code:

---

#include <QDeclarativeView>
#include <QDeclarativeContext>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QDeclarativeView *view = new QDeclarativeView();
    view->rootContext()->setContextProperty("UReceivedMessage", new Tool);
    view->setSource(QUrl("qrc:/qml/main.qml"));
    view->show();
 
    return a.exec();
}

Tool must be a QObject - see setContextProperty() declaration.

That's right thanks a lot ! :)
