The short answer is, "yes". The long answer is, "Yes, but it's not going to be easy". The only way to do this is is to get a reference to the decoration and set its
Colors attribute. The problem is that the only way to get a reference to the decoration is by getting the
Panel.Decorations[] property of the VI, which is an array of references to all the decorations on the VI's Front Panel. Unfortunately there is no way to single out which decoration is which. You will simply have to test to find which element in the array corresponds to your decoration of interest (if you have more than one decoration). Also, you need to close all of these references generated by property nodes, otherwise you will have a memory leak if you keep calli
ng the code in a loop. Take a look at the attached example.
Good luck,
Jim
