I'm trying to connect a signal from a timer to a class I've created, that inherits QGLWidget. When I connect it the old way, it works -

connect(m_pTickTimer, SIGNAL(timeout()), this, SLOT(update()));

But when I try the new way -

connect(m_pTickTimer, &QTimer::timeout, this, &imageDisplay::update);

I get a compilation error -

error: no matching function for call to 
'imageDisplay::connect(QTimer*&, void (QTimer::*)(QTimer::QPrivateSignal), imageDisplay*, <unresolved overloaded function type>)'

Is it because I don't override the update() slot in my class?

`update` is not a slot, I recommend not to overwrite the method. What do you want to do exactly? – eyllanesc Aug 20 '17 at 14:48
@peppe, Thank you very much! It really was just the overloading issue. Now working. – JLev Aug 21 '17 at 10:38
