How to use QMetaObject::invokeMethod?

[niko]

my testcase:

class test : public QObject
{
    Q_OBJECT
public slots:
    void foo() {
        qDebug() << "foo called";
    }
};
 
int main(int argc, char** argv)
{
    QApplication app(argc,argv);
    test* x = new test;
    x->foo(); //works
    QTimer::singleShot(0, x, SLOT(foo())); //works
    QMetaObject::invokeMethod(x, SLOT(foo())); //doesn't work
    app.exec();
}
#include "main.moc"

class test : public QObject
{
    Q_OBJECT
public slots:
    void foo() {
        qDebug() << "foo called";
    }
};
 
int main(int argc, char** argv)
{
    QApplication app(argc,argv);
    test* x = new test;
    x->foo(); //works
    QTimer::singleShot(0, x, SLOT(foo())); //works
    QMetaObject::invokeMethod(x, SLOT(foo())); //doesn't work
    app.exec();
}
#include "main.moc"

what's wrong? Why doesn't this work? (invoceMethod returns false - which means that the method is not found)

thanks,

QMetaObject::invokeMethod(x, "foo");

QMetaObject::invokeMethod(x, "foo");

Try without the SLOT() macro.

of course - it all is written in the docs
