通过新线程在python中打开wx.frame

你不需要线程。缺点是启动窗口在加载时会阻塞,但只有当您想更新它的内容(对其进行动画处理)或希望能够拖动它时,这才是一个问题。可以通过定期调用解决的问题 wx.SafeYield 例如。

import time
import wx


class Loader(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None)
        sizer = wx.BoxSizer(wx.VERTICAL)
        self.SetSizer(sizer)
        self.btn1 = wx.Button(self, label="Option 1")
        self.btn2 = wx.Button(self, label="Option 2")
        sizer.Add(self.btn1, flag=wx.EXPAND)
        sizer.Add(self.btn2, flag=wx.EXPAND)
        self.btn1.Bind(wx.EVT_BUTTON, self.OnOption1)
        self.btn2.Bind(
            wx.EVT_BUTTON, lambda e: wx.MessageBox("There is no option 2")
        )

    def OnOption1(self, event):
        self.btn1.Hide()
        self.btn2.Hide()
        self.Sizer.Add(
            wx.StaticText(self, label="Loading Option 1..."),
            1, wx.ALL | wx.EXPAND, 15
        )
        self.Layout()
        self.Update()
        AppFrame(self).Show()

class AppFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent)
        time.sleep(3)
        parent.Hide()

        # the top window (Loader) is hidden so the app needs to be told to exit
        # when this window is closed
        self.Bind(wx.EVT_CLOSE, lambda e: wx.GetApp().ExitMainLoop())


app = wx.PySimpleApp()
app.TopWindow = Loader()
app.TopWindow.Show()
app.MainLoop()
