Dynamically Disable Checkbox in wxpython

So I have a wxpython app where I would like to disable a checkbox widget when another checkbox is changed to false by the user. I currently use following code to set these two checkboxes to true. 

self.parentCheckbox.SetValue(True)
self.childCheckbox.SetValue(True)

Now I want to disable the childCheckbox since it's no longer relevant if the user makes the parentCheckbox false. I was hoping the following code would do this but it doesn't seem to be doing anything. 

if self.parentCheckbox.GetValue() == False:
    self.childCheckbox.Disabled()

To be sure, since it seems no one pointed that out: your code was okay except for one tiny letter.

self.childCheckbox.Disabled()

Instead the correct method name, of course, is Disable:

self.childCheckbox.Disable()

(Without the D: this time it's the action, not the test.)

The accepted answer seemed to integrate that but offered it mingled with a lot of code that wasn't (in my opinion) necessary to show you the error.

Hope that helps!

It's rough and ready but it shows how it can be done without pubsub.

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, "My Frame", size=(3000, 3000))
        self.panel = wx.Panel(self,-1)
        self.a = wx.CheckBox(self.panel, -1, "Apples", (20,100), (160,-1))
        self.b = wx.CheckBox(self.panel, -1, "Mango", (20,150), (160,-1))
        self.c = wx.CheckBox(self.panel, -1, "Banana", (20,200), (160,-1))
        self.d = wx.CheckBox(self.panel, -1, "Orange", (20,250), (160,-1))
        button=wx.Button(self.panel,label="Child",pos=(800, 400), size = (50,50))
        self.Bind(wx.EVT_BUTTON, self.newwindow, button)
        self.a.SetValue(True)

    def newwindow(self, event):
        secondWindow = window2(parent=self)
        secondWindow.Show()


class window2(wx.Frame):
    def __init__(self,parent):
        wx.Frame.__init__(self,parent, -1,'Window2', size=(1000,700))
        self.parent = parent
        self.panel=wx.Panel(self, -1)
        self.chk = wx.CheckBox(self.panel, -1, "Apples", (20,100), (160,-1))
        self.Bind(wx.EVT_CHECKBOX, self.Check)
        self.SetBackgroundColour(wx.Colour(100,100,100))
        self.Centre()
        self.Show()

def Check(self,event):
    if self.chk.IsChecked() == True:
        self.parent.a.SetValue(False)
        self.parent.a.Disable()
    else:
        self.parent.a.SetValue(True)
        self.parent.a.Enable()
    self.parent.Update()

app = wx.App()
frame = MyFrame()
frame.Show(True)
app.MainLoop()
