Question

我的程序正在打开时，我做了一个显示启动画面的代码。

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，启动画面会出现并消失。我用两行代码修复它，但它很难看：

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：为什么当我用第一个代码关闭程序并且你有一个最好的解决方案而不是第二个代码时会出现闪屏？

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＆＃39; MyApp＆＃39;并在OnInit方法中显示创建的启动。

这是一个基于我前段时间做过的一些工作样本，以及演示中的内容。

    app.MainLoop()

正确关闭闪屏
