What kind of code is executed when clicking on Start?

The UI will be blocked until that code returns. If it is some kind of lengthy task, you must create a thread and execute that code inside the thread. See http://doc.qt.io/qt-5/thread-basics.html.

Use a worker thread to transfer your data, or at least use PeekMessage to poll your message queue to see if there are any messages.
