Catch signal with lambda expression

[Stephan Lorenzen]

Hi guys,
Why does that work

QPushButton *butOK = new QPushButton("OK");
connect(butOK, &QPushButton::clicked, [=]()  { ... });

But this

QSpinBox *spinMin = new QSpinBox();
connect(spinMin, &QSpinBox::valueChanged, [=]() {butOK->setEnabled(true);});

does not work?? The compiler complains
"No matching function for call to connect(QSpinBox*&, <unresolved overloaded function type>, function()::<lambda(QVariant)>::lambda()>)" ,
but that sounds very cryptic to me.
Is it possible to catch QSpinBox::valueChanged with a lambda?
