关闭正常闪屏

Question

我做了一个代码，当我的程序正在打开时显示一个闪屏。

def main(): 
    application = wx.App(False) 
    splash = show_splash() 
    frame = MainWindow() 
    frame.Show(True) 
    splash.Destroy() 
    application.MainLoop() 

但是在程序关闭之前，启动画面出现并消失。 我的两行代码固定的，但它的丑陋：

def main(): 
    application = wx.App(False) 
    splash = show_splash() 
    frame = MainWindow() 
    frame.Show(True) 
    splash.Destroy() 
    splash.Hide() 
    application.MainLoop() 
    plash.Destroy() 

我的问题是：为什么启动画面当我关闭PROGRAMM与第一码和你有一个最佳的解决方案，而不是第二个码的出现？

看看wxPython演示。实际的演示代码有一个启动画面。它实现了一个'MyApp'，并且在OnInit方法中显示创建的飞溅。

这里的一个工作示例基于一些我以前做过的东西以及在演示中做了什么。
