Question

由于某种原因，我无法更新第二个标签。我通过询问输入并打印出字符串来测试它并且它起作用所以我显然没有正确地编写标签更新功能。有什么想法吗？

import wx
import time


class LeftPanel(wx.Panel):
    def __init__(self, parent, id):
        wx.Panel.__init__(self, parent, id, style=wx.BORDER_SUNKEN)
        self.text = parent.GetParent().rightPanel.text
        self.text_2 = parent.GetParent().rightPanel.text_2
        button1 = wx.Button(self, -1, 'Count', (10, 10))
        button2 = wx.Button(self, -1, 'Countdown', (10, 60))
        button3 = wx.Button(self, -1, 'Action', (10, 110))
        self.Bind(wx.EVT_BUTTON, self.OnPlus, id=button1.GetId())
        self.Bind(wx.EVT_BUTTON, self.OnMinus, id=button2.GetId())
        self.Bind(wx.EVT_BUTTON, self.button_Pressed, id=button3.GetId())
        self.timed_Out = 1     


    def OnPlus(self, event):
        value = 1
        for t in range(50):
            value = value + 1
            time.sleep(1)
            wx.Yield()
            self.text.SetLabel(str(value))

    def OnMinus(self, event):

        value = 60
        for t in range(value):
            value = value - 1
            time.sleep(1)
            wx.Yield()
            self.text.SetLabel(str(value/60) + ':' + str(value%60))

        self.timed_Out = 0
        self.text_2.SetLabel(str('End o\'line.'))

    def button_Pressed(self, event):
        if self.timed_Out == 1:
            if self.text_2 == 'First':
                self.text_2.SetLabel('Second')

            elif self.text_2 == 'Second':
                 self.text_2.SetLabel('First')


class RightPanel(wx.Panel):
    def __init__(self, parent, id):
        wx.Panel.__init__(self, parent, id, style=wx.BORDER_SUNKEN)
        self.text = wx.StaticText(self, -1, '0', (10,60))
        self.text_2 = wx.StaticText(self,-1,'First',(10, 120))

class Communicate(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(600, 200))
        panel = wx.Panel(self, -1)
        self.rightPanel = RightPanel(panel, -1)
        leftPanel = LeftPanel(panel, -1)
        hbox = wx.BoxSizer()
        hbox.Add(leftPanel, 1, wx.EXPAND | wx.ALL, 4)
        hbox.Add(self.rightPanel, 1, wx.EXPAND | wx.ALL, 5)
        panel.SetSizer(hbox)
        self.Centre()
        self.Show(True)



app = wx.App()
Communicate(None, -1, 'widgets communicate')
app.MainLoop()

Answer 1

在button_Pressed中，您正在测试self.text_2与"First"或"Second"的平等，但text_2是StaticText对象，而不是一个字符串，所以测试不起作用。试试这个：

if self.text_2.GetLabelText() == 'First':

为什么我的第二个标签没有更新？
