[PyX-user] A general symbol attr?

[Armin S. <li...@ar...>]

Hi,

when writing the point() function for SimplyDraw, I reused functions like 
pyx.graph.style._circlesymbol from the graph styles. I'm not really satisfied 
with my type=dot parameter, because I think it would be more PyX like to 
handle the type via an attr perhaps named symbol.

To fix ideas I therefore wrote this symbol attribute (I have attached the file 
where it is defined). Using this for a new implementation of canvas.point() 
one would be able to do e.g.
  point(x, y)
  point(x, y, symbol.cross)
  point(x, y, symbol.dot([rbg.red]))
  point(x, y, symbol.plus(size=.3)).
I have never written an attribute class before, so I might have mixed some 
things. Nevertheless I hope that the new point() function behaves more 
PyXic ;)

Now I wonder if such an attribute could have more usage as just in the point() 
function. One idea could be a path decorator that places symbols at the edges 
of a path. Unfortunately I didn't see an easy way for getting the vertices of 
a path as the points supplied e.g. to lineto seem not to get stored for 
retrieval.

Cheers
