python建立窗体后，使用mainloop显示窗体，如何使用多线程在窗体中实时显示时间？

Question

class MainForm(wx.Frame):

    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent,
                          id,
                          title="test",
                          pos=(200, 150),
                          size=(900, 600))
        MainForm_Panel = wx.Panel(self)
        MainForm_Font = wx.Font(11, wx.DEFAULT, wx.DEFAULT, wx.NORMAL)

        self.MainForm_SystemTime_Label = wx.StaticText(MainForm_Panel,
                                                       id,
                                                       label=datetime.datetime.now().strftime(GUIParameter.system_time),
                                                       pos=(705, 540),
                                                       style=wx.TE_RIGHT)

if __name__ == '__main__':
    app = wx.App()
    frame = MainForm(parent=None, id=-1)
    frame.Show()
    app.MainLoop()

你开的多线程，将窗口的对象作为参数传进去，然后修改对象的控件就行了

import threading

import wx
import datetime
class MainForm(wx.Frame):

    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent,
                          id,
                          title="test",
                          pos=(200, 150),
                          size=(900, 600))
        self.id = id
        self.MainForm_Panel = wx.Panel(self)
        MainForm_Font = wx.Font(11, wx.DEFAULT, wx.DEFAULT, wx.NORMAL)

        self.MainForm_SystemTime_Label = wx.StaticText(self.MainForm_Panel,
                                                       self.id,
                                                       label=datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
                                                       pos=(705, 540),
                                                       style=wx.TE_RIGHT)

def task(frame):
    while 1:
        frame.MainForm_SystemTime_Label.Label = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')

if __name__ == '__main__':
    app = wx.App()
    frame = MainForm(parent=None, id=-1)
    frame.Show()
    t = threading.Thread(target=task, args=(frame,))
    t.setDaemon(True)
    t.start()

    app.MainLoop()
