/******************************************************************************
 * File: CDeviceUI.cpp
 *
 * Desc:
 *
 * CDeviceUI is a helper that holds all the views and a bunch of
 * information for a specific device.  It has a CFlexWnd whose
 * handler it sets to the CDeviceView for the current view,
 * thus reusing one window to implement multiple pages.
 *
 * All CDeviceViews and CDeviceControls have a reference to the CDeviceUI
 * that created them (m_ui).  Thus, they also have access to the
 * CUIGlobals, since CDeviceUI has a reference to them (m_ui.m_uig).
 * CDeviceUI also provides the following read-only public variables
 * for convenience, all referring to the device this CDeviceUI
 * represents:
 * 
 * const DIDEVICEINSTANCEW &m_didi;
 * const LPDIRECTINPUTDEVICE8W &m_lpDID;
 * const DIDEVOBJSTRUCT &m_os;
 *
 * See usefuldi.h for a description of DIDEVOBJSTRUCT.
 *
 * CDeviceUI communicates to the rest of the UI via the CDeviceUINotify
 * abstract base class.  Another class (in our case CDIDeviceActionConfigPage)
 * must derive from CDeviceUINotify, and define the DeviceUINotify() and
 * IsControlMapped() virtual functions.  This derived class must be passed as
 * the last parameter to CDeviceUI's Init() function.  All the views and 
 * controls within the views notify the UI of user actions via m_ui.Notify(),
 * so that all actionformat manipulation can be done in the page class.  The
 * views and controls themselves never touch the actionformat.  See the
 * DEVICEUINOTIFY structure below for information on the parameter passed
 * through Notify()/DeviceUINotify().
