蟒蛇/ wxPython的：在后台持续做功 [英] Python/wxPython: Doing work continuously in the background

问题描述

我正在做一个程序在Python运行模拟，用wxPython的界面。在程序中，你可以创建一个模拟和渲染程序（=计算）给你。渲染可能会非常耗时，有时。

I'm making a program for running simulations in Python, with a wxPython interface. In the program, you can create a simulation, and the program renders (=calculates) it for you. Rendering can be very time-consuming sometimes.

当用户启动一个模拟，并定义了一个初始状态，我希望程序连续地呈现模拟的背景下，当用户可能在程序中做不同的事情。有点像YouTube的风格的酒吧，填补了：你可以玩模拟最多只能被渲染的点

When the user starts a simulation, and defines an initial state, I want the program to render the simulation continuously in the background, while the user may be doing different things in the program. Sort of like a YouTube-style bar that fills up: You can play the simulation only up to the point that was rendered.

我应该如何运行的渲染功能？

How should I run the rendering function?

推荐答案

有一个在 wxPython的维基有关长时间运行的任务信息公平一点可能有用。他们基本上是使用一个线程， wx.PostEvent 来处理线程和主WX事件循环之间的通信。

There's a fair bit of info on the wxPython wiki about long running tasks that might be useful. They basically make use a thread and wx.PostEvent to handle communication between the thread and the main wx event loop.
