Been doing some searching for a refresh button but i need it to refresh everything in the gui Im doing sort of a basic gui with a check sheet so that we can run it on a machine after work has finished to see what is left to do like  does the internet work, can you hear audio, Is the machine activated  etc There will be red crosses and green ticks and after something has been fixed i need to refresh it so the ticks change colour if a task is completed I see there are bits about refreshing c
