如何调整我当前的启动画面以允许我的代码的其他部分在后台运行？

Question

目前我有一个闪屏.但是,它不能作为真正的启动画面 - 因为它会停止执行其余代码(而不是允许它们在后台运行).

这是我程序的当前(减少)结构,重要位显示完整.如何调整当前的启动画面以实际允许程序的其余部分在后台加载？在python中有可能吗？

谢谢!

class VFrams(wxFrame):
    wx.Frame.__init__(self, parent, -1, _("Software"), 
                      size=(1024, 768), style=wx.DEFAULT_FRAME_STYLE)
    (a lot of code goes in here)

class MySplashScreen(wx.SplashScreen):
    def __init__(self, parent=None):
        aBitmap = wx.Image(name=VarFiles["img_splash"]).ConvertToBitmap()
        splashStyle = wx.SPLASH_CENTRE_ON_SCREEN | wx.SPLASH_TIMEOUT
        splashDuration = 5000 # ms
        wx.SplashScreen.__init__(self, aBitmap, splashStyle, splashDuration, parent)
        self.Bind(wx.EVT_CLOSE, self.CloseSplash)
        wx.Yield()
    def CloseSplash(self, evt):
        self.Hide()
        global frame
        frame = VFrame(parent=None)
        app.SetTopWindow(frame)
        frame.Show(True)
        evt.Skip()

class MyApp(wx.App):
    def OnInit(self):
        MySplash = MySplashScreen()
        MySplash.Show()
        return True

if __name__ == '__main__':
    DEBUG = viz.addText('DEBUG:', viz.SCREEN)
    DEBUG.setPosition(0, 0)
    DEBUG.fontSize(16)
    DEBUG.color(viz.BLACK)
    Start_Mainvars()        
    Start_Config()
    Start_Translation()
    Start_DB()
    Start_Themes()
    Start_Gui()
    Start_Get_Isos()
    Start_Bars()
    Start_Menus()
    Start_Event_Handlers()
    app = MyApp()
    app.MainLoop()

感谢您的所有帮助,这是我更改代码的方式(遵循提供的建议):

def show_splash():
    # create, show and return the splash screen
    global splash
    bitmap = wx.Image(name=VarFiles["img_splash"]).ConvertToBitmap()
    splash = wx.SplashScreen(bitmap, wx.SPLASH_CENTRE_ON_SCREEN|wx.SPLASH_NO_TIMEOUT, 0, None, -1)
    splash.Show()
    return splash

class MyApp(wx.App):
    def OnInit(self):
        global frame, splash
        splash = show_splash()
        Start_Config()
        Start_Translation()
        Start_DB()
        Start_Themes()
        Start_Gui()
        Start_Get_Isos()
        Start_Bars("GDP1POP1_20091224_gdp", "1 pork")
        Start_Menus()
        Start_Event_Handlers()
        frame = VFrame(parent=None)
        frame.Show(True)
        splash.Destroy()
        return True

if __name__ == '__main__':
    DEBUG = viz.addText('DEBUG:', viz.SCREEN)
    DEBUG.setPosition(0, 0)
    DEBUG.fontSize(16)
    DEBUG.color(viz.BLACK)
    Start_Mainvars()   
    app = MyApp()
    app.MainLoop()

你的代码非常混乱/复杂.没有必要覆盖wx.SplashScreen,没有理由你的启动画面关闭事件应该创建主应用程序窗口.这是我如何进行启动画面.

import wx

def show_splash():
    # create, show and return the splash screen
    bitmap = wx.Bitmap('images/splash.png')
    splash = wx.SplashScreen(bitmap, wx.SPLASH_CENTRE_ON_SCREEN|wx.SPLASH_NO_TIMEOUT, 0, None, -1)
    splash.Show()
    return splash

def main():
    app = wx.PySimpleApp()
    splash = show_splash()

    # do processing/initialization here and create main window
    frame = MyFrame(...)
    frame.Show()

    splash.Destroy()
    app.MainLoop()

if __name__ == '__main__':
    main()

只需尽快创建启动画面,不会超时.继续加载并创建应用程序的主窗口.然后摧毁闪屏,使其消失.显示启动画面不会阻止其他处理发生.
