+Tab Dialog Example
+===================
+
+Shows how to construct a tab dialog using the QTabWidget class.
+
+The Tab Dialog example consists of a single TabDialog class
+that provides three tabs, each containing information about
+a particular file, and two standard push buttons that are
+used to accept or reject the contents of the dialog.
