addWidget in qWidgetStack

[mickey]

Sorry but my 'w' is: MainForm w;

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
w->setLayout(l);
stackedWidget->addWidget(w);

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
w->setLayout(l);
stackedWidget->addWidget(w);

In anyway, your code get this error:

error C2248: 'QWidget::setLayout' : cannot access private member declared in class 'QWidget'
