显示限时消息wxPython

Question

我在 wxPython 中构建了一个应用程序，在该应用程序中我想在有限的时间内显示一条消息，然后它会自行消失（应用程序的用户不需要任何东西来让它消失) 我试过那样做，但它没有自己关闭。

dialog = wx.MessageDialog(None,'message', wx.OK | wx.ICON_INFORMATION | wx.STAY_ON_TOP)
threading.Timer(2.0, dialog.Destroy).start()
dialog.ShowModal()

我也试过这样做，但它什么也没做：

dialog = wx.MessageDialog(None,'message', wx.OK | wx.ICON_INFORMATION | wx.STAY_ON_TOP)
threading.Timer(2.0, dialog.EndModal,args=wx.ID_OK).start()
dialog.ShowModal()

我没有足够的上下文来了解你的计时器有什么问题。不过你可以试试这个。

import wx

# ================================================================================
class TimedDialog(wx.Dialog):

    def __init__(self, *args, **kwargs):
        super(TimedDialog, self).__init__(*args, **kwargs)

        self.SetSize((400, 300))
        self.SetTitle('Please wait!')
        self.Centre()

        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.OnTimer)

        self.timer.Start(2000)  # 2 second interval

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


# ================================================================================
class Example(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)

        self.InitUI()

    def InitUI(self):

        self.SetSize((300, 200))
        self.SetTitle('app')
        self.Centre()
        self.btn = wx.Button(self, -1, "click Me")
        self.btn.Bind(wx.EVT_BUTTON, self.OnClicked)

    def OnClicked(self, event):
        dlg = TimedDialog(self)
        dlg.ShowModal()


def main():

    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()


if __name__ == '__main__':
    main()

我使用 dialog.DestroyLater 让你的对话框关闭，但它并不一致，从准时到迟到 20 秒不等。几乎没有你想要的。
这是我 2 年前放在一起的东西，但现在不记得为什么了。
有点过头了，希望对你有帮助。
