-    The mask consists of a string of mask characters and separators,
-    optionally followed by a semicolon and the character used for
-    blanks. The blank characters are always removed from the text
-    after editing.

+    unmodified content can be read using displayText().

+    The hasAcceptableInput() method returns false if the current content of the
