我正在尝试将一个面板中已检查字符串的元组传递给另一个面板中的 textCtrl 小部件。我认为，如果我轮询包含复选框的复选框小部件的面板类并将其设置为等于包含 TextCtrl 小部件的面板类的属性，我可以根据选中的框在 TextCtrl 小部件中执行操作

我也尝试过使用 pubsub，但我遇到了困难，并且不确定您是否会使用它。

作为免责声明，我是面向对象编程和 python 的新手。我在学习面向对象编程方面取得了进展，但对我来说仍然有些模糊。

这是我的代码：

您可以在父类中进行事件绑定，因为它可以访问两个面板

我删除了所有评论，空格以减少行数。并在我更改/添加代码的地方添加了注释。(1),(2),(3)

import wx

class chkbxPanel(wx.Panel):
    def __init__(self, parent, resultsPanel):
        wx.Panel.__init__(self,parent=parent, id=-1)
        List = ['one','two','three']
        Prompt = 'Please Make a Choice'
        self.ChkBx = wx.CheckListBox(self,id=-1,choices=List,size=(-1,200))
        ### (1) Bind CHECKLISTBOX event (which is triggered when checkbox is toggled: checked/unchecked)
        self.ChkBx.Bind(wx.EVT_CHECKLISTBOX, lambda e: resultsPanel.changed(self.ChkBx.GetCheckedStrings()))
        ###
        self.PromptChkBx = wx.StaticText(self,id=-1,label=Prompt)
        self.panel_vertSizer=wx.BoxSizer(wx.VERTICAL)
        self.panel_vertSizer.Add(self.PromptChkBx,proportion=0,flag=wx.ALIGN_LEFT)
        self.panel_vertSizer.Add(self.ChkBx,proportion=0,flag=wx.ALIGN_LEFT)
        self.SetSizer(self.panel_vertSizer)
        self.Fit()

class resultsPanel(wx.Panel):
    def __init__ (self,parent):
        wx.Panel.__init__(self,parent=parent,id=-1)
        ResultsPanelTitle = 'Results:'
        self.ResultsTitle = wx.StaticText(self, id=-1, label= ResultsPanelTitle)
        self.Results = wx.TextCtrl(self, id=-1,size=(300,500),style=(wx.TE_MULTILINE|wx.TE_READONLY|wx.TE_DONTWRAP))
        self.panel_vertSizer = wx.BoxSizer(wx.VERTICAL)
        self.panel_vertSizer.Add(self.ResultsTitle,proportion=0, flag=wx.ALIGN_LEFT)
        self.panel_vertSizer.Add(self.Results, proportion=0, flag=wx.ALIGN_LEFT)
        self.SetSizer(self.panel_vertSizer)
        self.Fit()

    ### (2): Called when checkbox is toggled with checkbox strings as parameter. See (1)
    def changed(self, checked_strings):
        self.Results.AppendText('How Many Boxes are Checkd:\n')
        self.Results.AppendText(str(len(checked_strings))+'\n')
        self.Results.AppendText(str(checked_strings)+'\n')
    ###

class MainFrame(wx.Frame):
    def __init__(self):
        titleText = 'Wx Question'
        wx.Frame.__init__(self, None, title=titleText ,size=(600,300), style=wx.DEFAULT_FRAME_STYLE)
        frame_panel = wx.Panel(self)
        ### (3): Changed creation order. Passed resultsPanel instance to chkbxPanel creator
        RightPanel = resultsPanel(frame_panel)
        LeftPanel = chkbxPanel(frame_panel, RightPanel)
        ###
        RightPanel.CheckedBxs = LeftPanel.ChkBx.GetCheckedStrings()
        RightPanel.CheckedBxs = ('one','two')
        panelCtrls_horzSizer = wx.BoxSizer(wx.HORIZONTAL)
        panelCtrls_horzSizer.Add(LeftPanel)
        panelCtrls_horzSizer.Add(RightPanel)
        framePanel_vertSizer = wx.BoxSizer(wx.VERTICAL)
        framePanel_vertSizer.Add(panelCtrls_horzSizer)
        frame_panel.SetSizer(framePanel_vertSizer)
        frame_panel.Fit()
        self.SetSize((600,600))

if __name__ == '__main__':
    app = wx.PySimpleApp(redirect=False)
    appFrame = MainFrame().Show()
    app.MainLoop()
