[Visualpython-users] wire framed box

[Mike M. <mmu...@dg...>]

Hi,

enclosed is a class WireBox which implements as box which edges. That is I 
tried to have an object that behaves just like box() but instead of colored 
side plains it only has a wire frame of the edges.

The code works pretty much as I expected it to (just copy into an empty 
file and run it to see what I mean). The only problem is speed and memory 
consumption which is several orders of magnitude higher than for box(). 
Since I need several hundred or more boxes speed is kind of a problem.
Is there as possibility to include an edged box whether:

- by adding edgeColor and edgeRadius to the box object (default edgeColor = 
box().color --> no edge) and color = none to make the filled box() invisible


or

- by the means of an new object that inherits from box() but has the 
additional features (edgeColor, edgeRadius, color = none).



Also making my implementation faster would be an option.
Any ideas or hints are be appreciated.
Thanks.

Mike
