+## the default action. The return value is the number of the clicked button.
+## First button is number 0.

+## will return 0 if the first button (No) is clicked, etc.
+##
+## there are 6 meaningfull bitmap names: error, hourglass, info, questhead,
+##	question and warning. All arguments must be strings, except 'default'.
