    Question Passing data from worker thread to main GUI thread

    I need to pass data from worker thread (that reads from a serial port) and then pass the data to main GUI thread which needs to display the data. How can I achieve this?

    Use signals and slots or use a pointer to shared memory that you protect using a mutex. Reading the Qt documentation here and here would be a good place to start.
