The program has unexpectedly finished
-
Hello:
I am a new user QT in Windows.
I want to take an example and learn from that example. But no matter what project you use, always get the error
"The program has unexpectedly finished"
I would greatly appreciate some help that will let me use QT
regards

Hi and welcome to devnet,
Does it also happen with a default project generated with Qt Creator ?

It gives you an error message about the cause and a stack trace.

You provided the build output. What would be interesting is the debugger backtrace when your application crashes.
One thing you should check is that all the pointer you might be using are initialized and that you are not shadowing member variables in your constructors.
