如何在wxpython

Question

我有一个单选框，用户可以选择一个值。稍后，当用户单击“运行”按钮时，我想获取该单选框值并使用它。我不知道如何。本质上，您如何获得单选框选择的值并在程序中的其他位置使用它。我尝试过的其他方式仅返回默认选择，好像用户选择新值时无法识别

import wx

class MainFrame(wx.Frame):
    def __init__(self):
        title = "Example"
        wx.Frame.__init__(self, None, title=title, pos=(200,200), size=(400,100))

        panel_number = ChooseNumber(self)
        panel_calc = PerformCalc(self)

        boxh = wx.BoxSizer(wx.HORIZONTAL)
        boxh.Add(panel_number, 0, wx.EXPAND)
        boxh.Add(panel_calc, 0, wx.EXPAND)

        self.SetAutoLayout(True)
        self.SetSizer(boxh)
        self.Layout()

    def OnClose(self, event):
        self.Destroy()

class ChooseNumber(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent, style=wx.SIMPLE_BORDER, size=(200,100))

        lblList = ['1', '2']
        self.rbox = wx.RadioBox(self, id=wx.ID_ANY, label="Choose Number", choices=lblList)
        self.rbox.Bind(wx.EVT_RADIOBOX,  lambda event: self.onRadio())

        boxh = wx.BoxSizer(wx.HORIZONTAL)
        boxv = wx.BoxSizer(wx.VERTICAL)

        boxh.Add(self.rbox, 0, wx.CENTER)
        boxv.Add(boxh, 0, wx.CENTER)
        self.SetSizer(boxv)

    def onRadio(self):        

        if self.rbox.GetStringSelection() == "1":
            result = 1+5      
        else:
            result = 2*10

        print(result)

class PerformCalc(wx.Panel):
    def __init__(self, MainFrame):
        wx.Panel.__init__(self, MainFrame, id = wx.ID_ANY, style=wx.SIMPLE_BORDER, size=(200,100))

        txt = "Run Calculation"
        self.label = wx.StaticText(self, -1, txt, (0,0), (200,20), wx.ALIGN_CENTER)
        self.label.Wrap(150)

        file_button = wx.Button(self, label="Run")
        file_button.Bind(wx.EVT_BUTTON, self.RunProgram)

        #Set layout on panel-------------------------------------------------
        boxh = wx.BoxSizer(wx.HORIZONTAL)
        boxv = wx.BoxSizer(wx.VERTICAL)

        boxv.Add(self.label, 0, wx.CENTER)
        boxv.Add(file_button, 0, wx.CENTER)
        boxh.Add(boxv, 0, wx.CENTER)

        self.SetSizer(boxh)
        self.Layout()
        #---------------------------------------------------------------------

    def RunProgram(self, event):
        print("Run Calculation")

        answer = ChooseNumber.onRadio()

        print(answer)

def main():
    app = wx.App(redirect=True)
    top = MainFrame()
    top.Show()
    app.MainLoop()


if __name__ == "__main__":
    main()
