Re: [wxhaskell-devel] wxGraphicsRenderer
I tried this so far
which is copied from the basic Paint.hs from the sample.
- it compiles , run and break at run time if I omit Line [1]
gr <- graphicsContextCreate dc -- 1. this break for now
and it does not compile when I leave it on.
My sources are [1] and [2]
[1]: http://docs.wxwidgets.org/trunk/classwx_graphics_context.html
[2]: http://chandlerproject.org/Projects/WxPythonGraphicsContext
Ill keep you posted

ah many thanks ! I understand better now ( change quite a bit since 2003 :-) I indeed can see the classes . are these new renderers already mapped into wx, or should we use them as such , directly ? any sample / test available , out of chance ?
