//	NAME:  			TAppWin.H
// TYPE: 			C++ CLASS INTERFACE
//	DESCRIPTION:	Interface for the TAppWindow class

// SYNOPSIS:
/*****************************************************************
For an explanation of STLEx see readme.txt
TAppWindow is derived from TWindow and encapsulates most of the
functionality for the STLEx Program.

In addition to the event and command handling functions the database
and an iterator is encapsulated.
