.GetValue() is not working for TextCtrl in this particular case

Question

hey folks using Python i have bind the radio button and when that's clicked the TextCtrl is called upon but after I type in TextCtrl i am not able to get the string that has been entered, My code goes like this

def A(self,event):
    radiobut = wx.RadioButton(self.nameofframe, label = 'Opt-1', pos = (10,70),size= (90,-1))
    self.Bind(wx.EVT_RADIOBUTTON,self.B,radiobut)
def B(self,event):
    Str1 = wx.TextCtrl(self.nameofframe,pos = (100,70), size=(180,-1))
    print Str1.GetValue()

Could anyone please tell me where is the problem . Why can't i get it printed ?

Answer 1

Radio button usually comes within a group, one or more more than one, and one at least should clicked but you have only one button. What is usually used in such case is a check box, CheckBox.

In this example, it prints the text entered in TextCtrl when a CheckBox is activated:

#!python
# -*- coding: utf-8 -*-

import wx

class MyFrame(wx.Frame):
  def __init__(self, title):
    super(MyFrame, self).__init__(None, title=title)

    panel = wx.Panel(self)
    self.check = wx.CheckBox(panel, label='confiurm?', pos =(10,70), size=(90,-1))
    self.text  = wx.TextCtrl(panel, pos=(100,70), size=(180,-1))
    # disable the button until the user enters something
    self.check.Disable()

    self.Bind(wx.EVT_CHECKBOX, self.OnCheck, self.check)
    self.Bind(wx.EVT_TEXT, self.OnTypeText, self.text)

    self.Centre()

  def OnTypeText(self, event):
    '''
    OnTypeText is called when the user types some string and
    activate the check box if there is a string.
    '''
    if( len(self.text.GetValue()) > 0 ):
      self.check.Enable()
    else:
      self.check.Disable()

  def OnCheck(self, event):
    '''
    Print the user input if he clicks the checkbox.
    '''
    if( self.check.IsChecked() ):
      print(self.text.GetValue())

class MyApp(wx.App):
  def OnInit(self):
    self.frame = MyFrame('Example')
    self.frame.Show()
    return True

MyApp(False).MainLoop()

This is how it works:
