一个如下图所示的简单GUI界面

实现的功能也非常简单，在主窗口输入字符，点击复制就在副窗口出现相同的字符。点击清空同时清空主副窗口内的字符。

代码如下：

首先是写GUI界面

import wx
import wx.xrc
class test_0(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent, id=wx.ID_ANY, title=wx.EmptyString, pos=wx.DefaultPosition,
                          size=wx.Size(400, 250), style=wx.DEFAULT_FRAME_STYLE | wx.TAB_TRAVERSAL)

        self.SetSizeHintsSz(wx.DefaultSize, wx.DefaultSize)

        bSizer1 = wx.BoxSizer(wx.VERTICAL)

        self.m_staticText1 = wx.StaticText(self, wx.ID_ANY, u"主窗口", wx.DefaultPosition, wx.DefaultSize, 0)
        self.m_staticText1.Wrap(-1)
        bSizer1.Add(self.m_staticText1, 0, wx.ALL, 5)

        self.m_textCtrl1 = wx.TextCtrl(self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.DefaultSize, 0)
        bSizer1.Add(self.m_textCtrl1, 0, wx.ALL, 5)

        self.m_staticText2 = wx.StaticText(self, wx.ID_ANY, u"副窗口", wx.DefaultPosition, wx.DefaultSize, 0)
        self.m_staticText2.Wrap(-1)
        bSizer1.Add(self.m_staticText2, 0, wx.ALL, 5)

        self.m_textCtrl2 = wx.TextCtrl(self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.DefaultSize, 0)
        bSizer1.Add(self.m_textCtrl2, 0, wx.ALL, 5)

        self.m_button1 = wx.Button(self, wx.ID_ANY, u"复制", wx.DefaultPosition, wx.DefaultSize, 0)
        bSizer1.Add(self.m_button1, 0, wx.ALL, 5)

        self.m_button2 = wx.Button(self, wx.ID_ANY, u"清空", wx.DefaultPosition, wx.DefaultSize, 0)
        bSizer1.Add(self.m_button2, 0, wx.ALL, 5)

        self.SetSizer(bSizer1)
        self.Layout()

        self.Centre(wx.BOTH)

        # Connect Events
        self.m_button1.Bind(wx.EVT_BUTTON, self.copy_0)
        self.m_button2.Bind(wx.EVT_BUTTON, self.clear_0)

    def __del__(self):
        pass

    # Virtual event handlers, overide them in your derived class
    def copy_0(self, event):
        event.Skip()

    def clear_0(self, event):
        event.Skip()

　　然后是调用程序:

import wx
import t1st_0
class t1st_2(t1st_0.test_0):
    def text_1(self):
        self.m_textCtrl1.SetValue(‘你好‘)

    def clear_0(self,event):#清空窗口中的内容
        self.m_textCtrl1.Clear()
        self.m_textCtrl2.Clear()
    def copy_0(self,event):
        self.text_11 = self.m_textCtrl1.GetValue()
        self.m_textCtrl2.SetValue(self.text_11)
if __name__ == ‘__main__‘:
    app = wx.App()
    # None表示的是此窗口没有上级父窗体。如果有，就直接在父窗体代码调用的时候填入‘self’就好了。
    main_win = t1st_2(None)
    main_win.text_1()#设置窗口初值

    main_win.Show()
    app.MainLoop()
