◆ run()

void QBBScreenEventThread::run ( void )

protectedvirtual

The starting point for the thread.

After calling start(), the newly created thread calls this function. The default implementation simply calls exec().

You can reimplement this function to facilitate advanced thread management. Returning from this method will end the execution of the thread.

Reimplemented from QThread.
