I've an event structure that finds the ROIs of an image. Initially I have these ROI displayed immediately (within the same even structure) after they are found. However, I would like to make it possible to be able to change the ROI color while the VI is still running. Hence I thought I should use the property node to pass the ROIs out of the event structure and use another event structure to create code for the ROI color change. My code however isn't able to run once when the ROI is found or when there is any changes to the ROIs (the first event structure enables user to change the score value to find matching ROIs). So the question is how to make the event case to start whenever a computed value is ready/available?
