wxPython + multiprocessing: Checking if a color string is legitimate

Question

I have a wxPython program with two processes: A primary and a secondary one (I'm using the multiprocessing module.) The primary one runs the wxPython GUI, the secondary one does not. However, there is something I would like to do from the secondary process: Given a string that describes a color, to check whether this would be legitimate color for wxPython. That means, whether I can create a wx.Pen(color_string) or not.

How do I do this?

(I tried making a wx.Pen and comparing its color to the null color, but that required to create a wx.App in the second process, and when I did create one the program raised an error in some special wxPython window.)

Answer 1

You could make two Queues between the two processes and have the second one delegate wx-related functionality to the first one (by pushing on the first queue the parameters of the task to perform, and waiting for the result on the second one).
