wxpython: another missing attribute

[John Salerno]

Ah, the object-oriented stuff is just so FUN! :) Here's my code,
followed by the error. I thought I was referring to the 'text' attribute
correctly, but it seems not.

import wx


class InputForm(wx.Fr ame):

def __init__(self, parent, id, title, pos=wx.DefaultP osition,
size=wx.Default Size, style=wx.DEFAUL T_FRAME_STYLE,
name='frame'):
wx.Frame.__init __(self, parent, id, title, pos, size, style, name)
panel = wx.Panel(self)
text = wx.StaticText(p anel, -1, 'Click results')
btnOK = wx.Button(panel , -1, 'OK')
self.Bind(wx.EV T_BUTTON, self.clickOK, btnOK)
btnCancel = wx.Button(panel , -1, 'Cancel')
self.Bind(wx.EV T_BUTTON, self.clickCance l, btnCancel)
sizer = wx.BoxSizer(wx. HORIZONTAL)
sizer.Add(btnOK , 0, wx.ALL, 10)
sizer.Add(btnCa ncel, 0, wx.ALL, 10)
sizer.Add(text, 0, wx.ALL, 10)
panel.SetSizer( sizer)

def clickOK(self, event):
self.text.SetLa bel('You clicked OK')

def clickCancel(sel f, event):
self.text.SetLa bel('You clicked Cancel')


class MyApp(wx.App):

def OnInit(self):
frame = InputForm(None, -1, 'Data Entry Form')
self.SetTopWind ow(frame)
frame.Show()
return True


app = MyApp()
app.MainLoop()

-------------------

Traceback (most recent call last):
File "C:\Python24\my scripts\wx_test s\wxtest.py", line 23, in clickOK
self.text.SetLa bel('You clicked OK')
AttributeError: 'InputForm' object has no attribute 'text'

This becomes a local var, i.e. local to __init__. To make it an instance var
write

self.text = wx.StaticText(p anel, -1, 'Click results')

Ah, more namespace trickery! Thanks! :)
