Detailed Description

Utility class to avoid Qt warning when accesing QLabels from differnt Threads.

QLabels can not be used from different Threads. So if a QLabel is created in in the main thread, it might not be set up to show another text/number from the working thread. As a workaround, the "label" component of the ICL GUI API uses not the original QLabel but this thread-save reimplementation called CompabilityLabel.
