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

[qtpat]

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:

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

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

To copy to clipboard, switch view to plain text mode 

Any help would be appreciated

Cheers !

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

[qtpat]

Tool class definition:

#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

#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);

#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();
}

#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 !
