≫ how did you connect the slot, did connect return true etc. And how are you verifying that this slot is not called? Have you put debugs there?

>Yes I put a break on that statement . I don’t understand how do I connect to the slot?

By calling QObject::connect().

Without connect a signal to a slot (see docs on how to use connect), the slot won't be called! :)

In the examples shown below I just added the below two functions to the same class. Now the control flows to changeevent on every event but not to finished on close. Why?

changeEvent() gets called because its a virtual function in QFileDialog and you're overloading it in your class (which i presume, you're extending from QFileDialog).

Before you go any deeper, I suggest you read up some tutorials on how to use signals/slots in Qt.
