42 * The UIMessageCenter class is a central place to handle all problem/error
43 * situations that happen during application runtime and require the user's
44 * attention.
45 *
46 * The role of this class is to describe the problem and/or the cause of the
47 * error to the user and give him the opportunity to select an action (when
48 * appropriate).
49 *
50 * Every problem situation has its own (correspondingly named) method in this
51 * class that takes a list of arguments necessary to describe the situation and
52 * to provide the appropriate actions. The method then returns the choice to the
53 * caller.
