[Guidolib-devel] GUIDOLib API proposal change

[Jerome B. <be...@gr...>]

Hi

I'm currently implementing a wxWindows version of the GuidoLib. In order to 
make it cross-platform, and to resolve some dependencies, such as fonts and 
graphics, I propose to add an initialization function to the Guido API:

int GuidoInit( GuidoInitDesc * desc );

GuidoInitDesc is defined as follow:
typedef struct
{
	GDevice	*	graphicDevice;		// NULL: use default device
	GuidoFeedback * 	feedback;		// NULL: no feedback
} GuidoInitDesc;

This function initialize the GuidoLib engine with the resources necessary 
to provide feedback at user level (but in charge of the client application) 
and to access the graphical device and fonts. Implementation of the 
corresponding objects is platform dependent. It ensures the engine portability.

Actually, this function should be called before any graphic layout, but as 
this layout is interleaved within parsing methods, it is better to 
recommend calling this function at initialization time.
