Set mouse tracking issue

[ChrisW67]

You are saying that this always outputs "Move" messages regardless of mouse buttons:

#include <QtGui>
#include <QDebug>
 
class MyView: public QGraphicsView {
    Q_OBJECT
public:
    MyView(QWidget *p = 0): QGraphicsView(p) 
    {
        resize(QSize(320, 240));
        qDebug() << hasMouseTracking();  // outputs false
    }
 
protected:
    void mouseMoveEvent( QMouseEvent * event )
    {
        qDebug() << "Move";
    }
};
 
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    MyView m;
    m.show();
 
    return app.exec();
}
#include "main.moc"

#include <QtGui>
#include <QDebug>

class MyView: public QGraphicsView {
    Q_OBJECT
public:
    MyView(QWidget *p = 0): QGraphicsView(p) 
    {
        resize(QSize(320, 240));
        qDebug() << hasMouseTracking();  // outputs false
    }

protected:
    void mouseMoveEvent( QMouseEvent * event )
    {
        qDebug() << "Move";
    }
};


int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    MyView m;
    m.show();

    return app.exec();
}
#include "main.moc"

To copy to clipboard, switch view to plain text mode 

Certainly doesn't here with Qt 4.7.4.

Post a small, compilable example that demonstrates the problem.
