關閉正常閃屏

Question

我做了一個代碼，當我的程序正在打開時顯示一個閃屏。

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

但是在程序關閉之前，啓動畫面出現並消失。 我的兩行代碼固定的，但它的醜陋：

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

我的問題是：爲什麼啓動畫面當我關閉PROGRAMM與第一碼和你有一個最佳的解決方案，而不是第二個碼的出現？

看看wxPython演示。實際的演示代碼有一個啓動畫面。它實現了一個'MyApp'，並且在OnInit方法中顯示創建的飛濺。

這裏的一個工作示例基於一些我以前做過的東西以及在演示中做了什麼。
