2// Name: drawer.cpp
3// Purpose: Drawer child window classes.
4// Drawer windows appear under their parent window and
5// behave like a drawer, opening and closing to reveal
6// content that does not need to be visible at all times.
7// Author: Jason Bagley
8// Modified by: Ryan Norton (To make it work :), plus bug fixes)
9// Created: 2004-30-01
