这是我写的代码。它确实关闭了窗口,但不显示其中的文本。我需要显示的文本,然后自动关闭窗口。我应该做些什么改变才能让它工作谢谢

这是代码

import wx
from time import sleep

class Frame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, title=title, size=(300,200))

        self.panel = wx.Panel(self)
        box = wx.BoxSizer(wx.VERTICAL)
        m_text = wx.StaticText(self.panel, -1, 'File Uploaded!')
        m_text.SetSize(m_text.GetBestSize())

        box.Add(m_text, 0, wx.ALL, 10)
        self.panel.SetSizer(box)
        self.panel.Layout()
        self.Bind(wx.EVT_ACTIVATE, self.onClose)

    def onClose(self, event):
        sleep(5)
        self.Destroy()

app = wx.App(redirect=True)
top = Frame('test')
top.Show()
app.MainLoop()

我建议使用 wx.Timer。如果您使用 time.sleep(),您将阻塞 wxPython 的主循环,这会使您的应用程序无响应。这是修改为使用计时器的代码:

import wx

class Frame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, title=title, size=(300,200))

        self.panel = wx.Panel(self)
        box = wx.BoxSizer(wx.VERTICAL)
        m_text = wx.StaticText(self.panel, -1, 'File Uploaded!')
        m_text.SetSize(m_text.GetBestSize())

        box.Add(m_text, 0, wx.ALL, 10)
        self.panel.SetSizer(box)
        self.panel.Layout()

        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.onClose, self.timer)
        self.timer.Start(5000)

    def onClose(self, event):
        self.Close()

app = wx.App(redirect=True)
top = Frame('test')
top.Show()
app.MainLoop()

>>> import wx
>>> import time
>>> app = wx.App()
>>> b = wx.BusyInfo('Upload Finished!')
>>> time.sleep(5)
>>> del b
