Tip of the Day Recipe"Tip of the day" is easily implemented with thewxCreateFileTipProviderfunction and a text file full of tips.Your application will need:Some sort of persistence to remember whether tips are being shown and which tip will be shown next. For this recipe, I'm just refe 阅读全文

IntroductionThe following was posted to the comp.lang.python newsgroup on 24-May-2001. Since it explains very well the options for keeping the GUI responsive when the application has to do long running tasks I decided to copy it here verbatim. Many thanks toDavid Bolenfor taking the time and effort 阅读全文

如果你经常使用python开发GUI程序的话，那么就知道，有时你需要很长时间来执行一个任务。当然，如果你使用命令行程序来做的话，你回非常惊讶。大部分情况下，这会堵塞GUI的事件循环，用户会看到程序卡死。如何才能避免这种情况呢？当然是利用线程或进程了！本文，我们将探索如何使用wxPython和theading模块来实现。wxpython线程安全方法wxPython中，有三个“线程安全”的函数。如果你在更新UI界面时，三个函数都不使用，那么你可能会遇到奇怪的问题。有时GUI也忙运行挺正常，有时却会无缘无故的崩溃。因此就需要这三个线程安全的函数：wx.PostEvent, wx.CallAfter和 阅读全文
摘要：
在GUI中进行多线程编程是一件很麻烦的事情，一直以来我都在寻找一个通用的方便的处理方法。在前一段时间中我曾经发表过关于长流程的处理，主要是在处理中插入一个对调度器的处理，而这个调度器使用了队列来实现子线程与主线程之间的数据通信。它的确可以解决一些问题，但并不是非常的方便。那么总结在wxPython中所提出的解决多线程问题的答案如下：不要在子线程中进行GUI的更新处理，所有的GUI的更新全部由GUI线程(主线程)来完成使用自定义事件来定义一个事件，然后就可以使用wxPostEvent来发送这个事件，这样会将这个事件放入主线程的事件循环中，从而使用事件得以安全的处理。使用线程安全的队列(Queue 阅读全文
