Parameters:

session - The Guise session in which this event was generated.

source - The layout that fired the event.

component - The component for which a constraint value changed.

constraints - The constraints for which a value changed.

propertyName - The programmatic name of the property that was changed.

oldValue - The old value of the property, or null if no old value is not available.

newValue - The new value of the property, or null if the new value is not available.
