WxPython StaticText动态更新

Question

def update_text(self, info):
        index = {
            "username":self.username,
            "online status":self.online_status,
            "dial status":self.dialing_status,
            "dtmf transfer number":self.DTMF_t_num,
            "dtmf number":self.DTMF_num,
            "program status":self.program_status,
            "credits":self.credits}
        text = index[info[0]]
        data = info[1]
        append = info[2]
        if append:
            current = text.GetLabel()
            text.SetLabel(current + " " +data)
        else:
            text.SetLabel(data)

为什么不更新wx。它所指的静态文本？"索引"中的每个变量都引用了一个静态文本。

没有一些可运行的代码很难说。我做了我自己的事情，并使它发挥了作用：

import random
import wx
########################################################################
class MyPanel(wx.Panel):
    """"""
    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)
        self.username = wx.StaticText(self, label="username")
        self.online_status = wx.StaticText(self, label="offline")
        self.dialing_status = wx.StaticText(self, label="no dial tone")
        btn = wx.Button(self, label="Update")
        btn.Bind(wx.EVT_BUTTON, self.onUpdate)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.username, 0, wx.ALL, 5)
        sizer.Add(self.online_status, 0, wx.ALL, 5)
        sizer.Add(self.dialing_status, 0, wx.ALL, 5)
        sizer.Add(btn, 0, wx.ALL, 5)
        self.SetSizer(sizer)
    #----------------------------------------------------------------------
    def update_text(self, info):
        """"""
        index = {
            "username":self.username,
            "online status":self.online_status,
            "dial status":self.dialing_status
            }
        text = index[info[0]]
        data = info[1]
        append = info[2]
        if append:
            current = text.GetLabel()
            text.SetLabel(current + " " + data)
        else:
            text.SetLabel(data)
    #----------------------------------------------------------------------
    def onUpdate(self, event):
        """"""
        info = random.choice(
            [("username", "mork89", 1),
             ("online status", "online", 0),
             ("dial status", "dialing", 1)
             ])
        self.update_text(info)
########################################################################
class MainFrame(wx.Frame):
    """"""
    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Dynamic StaticText")
        panel = MyPanel(self)
        self.Show()
if __name__ == "__main__":
    app = wx.App(False)
    frame = MainFrame()
    app.MainLoop()

也许我的代码能帮你弄清楚你的代码。
