Additional Inherited Members
Public Types inherited from Draw_Window
typedef void(*	FCallbackBeforeTerminate) ()
	Type of the callback function that is to be passed to the method AddCallbackBeforeTerminate().
Static Public Member Functions inherited from Draw_Window
static void	AddCallbackBeforeTerminate (FCallbackBeforeTerminate theCB)
	This method registers a callback function that will be called just before exit. This is useful especially for Windows platform, on which Draw is normally self-terminated instead of exiting.
static void	RemoveCallbackBeforeTerminate (FCallbackBeforeTerminate theCB)
	Just in case method for un-registering a callback previously registered by AddCallbackBeforeTerminate().
static bool	DefineColor (const int theIndex, const char *theColorName)
static void	Flush ()
	XFlush() wrapper (X11), has no effect on other platforms.
Protected Member Functions inherited from Draw_Window
	Draw_Window (const char *theTitle, const NCollection_Vec2< int > &theXY, const NCollection_Vec2< int > &theSize, Aspect_Drawable theParent, Aspect_Drawable theWin)
	Main constructor.
void	init (const NCollection_Vec2< int > &theXY, const NCollection_Vec2< int > &theSize)
	Initialize the window.
