How to handle key press events with the QPlainTextEdit

Question

I've been developing with QT for around a week now and am pleased to say that I'm picking it up really fast. I'm an intermediate C++ programmer but picking up some parts of QT is proving to be challenging. I need to process key press events from the QPlainTextEdit when the user presses enter and I presume that the solution will involve sub classing the widget. Can any of you smart guys give me a potential implementable solution?

Answer 1

To really understand Qt and event handling there are two key areas of the documentation you should read. The first is the overview on The Event System and the second is a very important bit which is a cleverly hidden link on that page for QCoreApplication::notify. They should really move that to the main page of the Event System documentation as it really makes things quite clear (to me at least).
