//===========================================================================
// Summary:
//     The CSPWinThemeWrapper class wraps the UxTheme.dll visual theme
//     API.  You can use this class for rendering Windows XP themes for
//     owner drawn controls.
//===========================================================================
class  CSPWinThemeWrapper

	//-----------------------------------------------------------------------
	// Summary:
	//     Shared data of wrappers
	//-----------------------------------------------------------------------
	class CSharedData

	//     deallocation.
	//-----------------------------------------------------------------------
	virtual ~CSPWinThemeWrapper();

	//-----------------------------------------------------------------------
	// Summary:
	//     Open the theme data for the specified HWND and semi-colon
	//     separated list of class names.  OpenThemeData() will try
	//     each class name, one at a time, and use the first matching
	//     theme info found.
	// Parameters:
	//     hWnd         - Window handle of the control/window to be
	//                    themed.
	//     pszClassList - Class name (or list of names) to match to
	//                    theme data section.  if the list contains
	//                    more than one name, the names are tested one
	//                    at a time for a match.  If a match is found,
	//                    OpenThemeData() returns a theme handle
	//                    associated with the matching class.  This
	//                    param is a list (instead of just a single
	//                    class name) to provide the class an
	//                    opportunity to get the "best" match between
	//                    the class and the current theme.  For example,
	//                    a button might pass L"OkButton, Button" if its
	//                    ID=ID_OK.  If the current theme has an entry
	//                    for OkButton, that will be used.  Otherwise,
	//                    we fall back on the normal Button entry.
	//-----------------------------------------------------------------------
	void OpenThemeData(HWND hWnd, LPCWSTR pszClassList);

	//-----------------------------------------------------------------------
	// Summary:
	//     Closes the theme data handle.  CSPWinThemeWrapper will do
	//     this automatically when destroyed or when OpenThemeData is
	//     called.  Your window should handle the WM_THEMECHANGED
	//     message when called followed by a call to OpenThemeData.
