Best canvas for drawing in wxPython?

Question

I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectio

Answer 1

It seems that OGL is not being updated, and in general FloatCanvas looks more modern. I don't really know deeply enough the two options.

It seems that event capturing is easier with FloatCanvas. I would try to use it before OGL.

Answer 2

I've tried FloatCanvas, although there has been a lot of work to get everything to work. I've managed to get through mouse interaction things like connectivity, movement, automatic reconnection in case of movement, etc.

FloatCanvas is also quite nice in terms of performance and visual results. Anti-aliasing (1) (2) is also possible to improve them if necessary.
