You are missing an object. Try one of these in the other cpp file:

KeyDialog kd;
kd.setKey( enter );

There is probably some other fundamental error in your code though. It
may be that your "setKey" function doesn't need an object and therefore
should not be in the KeyDialog class.

Wow, I feel a bit stupid...a bit of a duh moment...

I had:

KeyDialog dialog(this);
KeyDialog::setKey(enter);
dialog.exec();

When of course i needed to have:

KeyDialog dialog(this);
dialog.setKey(enter);
dialog.exec();

Thank you very much, your small bit of code helped tremendously
