wxPython check box not setting value - checkbox

Question

So I have a wxPython window I've made that was working fine, until I tried to add a new check box to give the user an option for asymmetry.
import poser
import random
import wx
import wx.py
import wx.aui
scene = poser.Scene()
man = poser.WxAuiManager()
root = man.GetManagedWindow()
fig = scene.CurrentFigure()
allowAsymetric = False
paramList = []
lst = ["Full Body Morphs","All Head/Face", "Face Shape", "Forehead","Eyes", "Ear", "Nose", "Cheek", "Chin/Jaw", "Lips"]
# Our dialog box
class userInput(wx.Frame):
def __init__(self, parent) :
# Call the parent class initialisation method
wx.Frame.__init__(self, parent = parent, pos=wx.Point(675, 323), size=wx.Size(400, 400), style=wx.DEFAULT_FRAME_STYLE, title = "Random Hive")
global lst, allowAsymetric
# Set up the UI
#self.CenterOnScreen(wx.BOTH)
self.panel = wx.Panel(self,id=-1,size=(400,350))
self.panel.SetBackgroundColour("#4B4B4B")
# Checklist
self.lb = wx.CheckListBox(self.panel, -1, (20, 20), (350,200), lst)
#Select All Button
self.SelectALL = wx.Button(self.panel,id=100,pos=(20,260),size=(-1,- 1),label="Select All")
self.SelectALL.SetBackgroundColour("#5D5D5D")
self.SelectALL.SetForegroundColour("#CBCBCB")
self.SelectALL.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.SelectALL.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Bind(wx.EVT_BUTTON, self.OnSelectALL, self.SelectALL)
#Select None Button
self.SelectNONE = wx.Button(self.panel,id=110,pos=(150,260),size=(-1,- 1),label="Select None")
self.SelectNONE.SetBackgroundColour("#5D5D5D")
self.SelectNONE.SetForegroundColour("#CBCBCB")
self.SelectNONE.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.SelectNONE.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Bind(wx.EVT_BUTTON, self.OnSelectNONE, self.SelectNONE)
#Inversion Button
self.SelectINVERT = wx.Button(self.panel,id=120,pos=(275,260),size=(- 1,-1),label="Invert Selection")
self.SelectINVERT.SetBackgroundColour("#5D5D5D")
self.SelectINVERT.SetForegroundColour("#CBCBCB")
self.SelectINVERT.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.SelectINVERT.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Bind(wx.EVT_BUTTON, self.OnSelectINVERT, self.SelectINVERT)
# Cancel button
self.Cancel = wx.Button(self.panel,id=140,pos=(20,310),size=(-1,-1),label="Close")
self.Cancel.SetBackgroundColour("#5D5D5D")
self.Cancel.SetForegroundColour("#CBCBCB")
self.Cancel.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.Cancel.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Cancel.Bind(wx.EVT_BUTTON, self.OnSelectCancel, self.Cancel)
# Ok button
self.OK = wx.Button(self.panel,id=150, pos=(275,310),size=(-1,-1),label="Apply")
self.OK.SetDefault()
self.OK.SetBackgroundColour("#5D5D5D")
self.OK.SetForegroundColour("#CBCBCB")
self.OK.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.OK.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Bind(wx.EVT_BUTTON, self.OnSelectOK, self.OK)
#Undoe Button
self.Undo = wx.Button(self.panel, id = 130, pos = (150,310), size= (-1,-1), label = "Undo Morphs")
self.Undo.SetBackgroundColour("#5D5D5D")
self.Undo.SetForegroundColour("#CBCBCB")
self.Undo.Bind(wx.EVT_ENTER_WINDOW, self.OnMouseOver)
self.Undo.Bind(wx.EVT_LEAVE_WINDOW, self.OnMouseLeave)
self.Bind(wx.EVT_BUTTON, self.OnUndo, self.Undo)
#static text
self.infoLable = wx.StaticText(self.panel, pos = (20,230),label = 'Enter Morph Value')
self.morphNumber = wx.TextCtrl(self.panel, pos = (150,230))
self.asym = wx.CheckBox(self.panel, label='Asymetric', pos=(275, 230))
#asym.SetValue(False)
#asym.Bind(wx.EVT_CHECKBOX, self.AsymetricOn)
self.Bind(wx.EVT_CHECKBOX, self.AsymetricOn, self.asym)
def AsymetricOn(self, event):
sender = event.GetEventObject()
if sender.GetValue() == True:
allowAsymetric = True
else:
allowAsymetric = False
print allowAsymetric
def OnSelectALL(self,event):
i=0
while i < len(lst):
self.lb.Check(i,True)
i=i+1
def OnSelectNONE(self,event):
i=0
while i < len(lst):
self.lb.Check(i,False)
i=i+1
def OnSelectINVERT(self,event):
i=0
while i < len(lst):
if self.lb.IsChecked(i) == True:
action = False
self.lb.Check(i,action)
i=i +1
continue
elif self.lb.IsChecked(i) == False:
action = True
self.lb.Check(i,action)
i=i+1
continue
i=i+1
def OnSelectOK(self,event):
fig.Memorize()
smn = self.morphNumber.GetString(0,self.morphNumber.GetLineLength(0))
try:
mN = float(smn)
print "before function choice asymetric is ", allowAsymetric
functionChoice(self.lb.GetCheckedStrings(), mN)
print "after is it ", allowAsymetric
except:
print 'Enter a morph value'
def OnUndo(self,event):
fig.Reset()
scene.Draw()
def OnSelectCancel(self,event):
#print "Cancel clicked"
self.Destroy()
def OnMouseOver(self,event):
element = event.GetEventObject()
element.SetBackgroundColour("#737373")
event.Skip()
def OnMouseLeave(self,event):
element = event.GetEventObject()
element.SetBackgroundColour("#5D5D5D")
event.Skip()
When the window pops up I can check and uncheck the box just fine, and I get printed out a correct value for allowAsymetry according to what I've clicked like so:
False
True
False
True
But as soon as I click my Ok/Apply button the value is false no matter what the check box shows:
before function choice asymetric is False
in function choice allowAsymetric is False
I can't figure out why the value of allowAsymetric keeps setting back to False.

Sadly your code will not run standalone, so I can't test it but it looks as if you have forgotten to declare global allowAsymetric in def AsymetricOn(self, event):
You can always access a global variable but if you are going to alter its value, you need to declare it as global or the variable simply becomes a local variable.
