I have been looking at Carl Worth's "lame attempt at fixing up the
xaralx code to use cairo instead of a proprietary CDraw.a" for the past
few hours. I have no experience with neither Xara nor Cairo, so I have a
1. Carl created stubs for function calls to CDraw functions, which are
to be replaced by Cairo functions. Wouldn't it be easier to derive a new
GDrawContext instead? This has been done originally with GDrawAsm as a
C++ wrapper for the assemblerfunctions in GDRAW.DLL. I think this would
at least save passing around contexts, and would be more object
2. I am so far struggling with the very basic: I need to set up a cairo
context. To do this, I need a "drawable", i.e. some canvas I can draw
to. I have found examples on how to do this from GTK/GDK, and I guess
wxWidget is using a GTK backend...
I think I need a pointer to some wxWidget-canvas or so, but I am not
sure where the link between the wxWidget frontend and the GDRAW backend
is supposed to be.
I hope someone can help me with this, so I can get started. I don't
really have a whole lot of time for this, but maybe we can get the cairo
backend into a reasonable state together.
