Qobject_cast, trying to determine object class...

[Zerby]

I have a MainWindow class, where in the eventFilter I have this:

@
...
case QEvent::ChildAdded:
{
QChildEvent ce =(QChildEvent)event;
QObject *obj = ce->child();
emit this->childAdded(obj);
break;
}
...@

Then I have the childAdded signal connected to MainWindow::handleAddedObject(QObject *obj). Inside that I do:

@
baseWidget *w = qobject_cast<baseWidget *>(obj);
if (w != 0) this->baseWidgetAdded(w);
@

Then I try it with:

@
MainWindow *w = new MainWindow();
baseWidget *w1 = new baseWidget(w);
@

The handleAddedObject -function get called, but the qobject_cast returns 0 everytime. It must be the baseWidget w1 that triggers the function calls, because if I comment out the line where I create the baseWidget object, the handleAddedObject is not called at all. What am I doing wrong?
