Is there a "hook" to the main eventloop that would be accessible to the code running in ipython. Thus a wx.CallAfter or alike in different toolkits, and other eventloop and multi-threaded programming tricks might be useful here. Maybe this solution would even provide the solution for blocking calls with MPL with most multi-threaded cases. The problem I hit in my first attempt was that the "connect" call executed in my function did not seem to be executed until the function returned. If I can connect a callback to the figure in the beginning of the function, then loop waiting and checking a parameter the will be set be the callback, then process the parameter when available. I do not see why this could not work, but then my understanding of multithreaded programming is quite poor. > This two-thread arrangement has a big drawback: the inability to > interrupt long-running calculations (even non-blocking ones) with > Ctrl-C, because it is simply impossible in Python to toss asynchronous > signals accross threads. Yes :-<. Have you tried getting some help from a guru, it seems to be worth the while.
