nb is a local variable within the __init__() method only.
This is the same as, e.g.:
def foo():
i = 0
def bar():
print i
The use of i in bar() is an error, because it is only assigned in
foo()
If you want to make it available to all methods within a class then
you need to attach it to the instance of that class, e.g.:
class MyFrame(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(600,500))
self.nb = wx.Notebook(self)
self.page1 = Form1(nb, -1)
self.nb.AddPage(self.page1, "Choose Patient")
self.page1.SetFocus()
def patient_lookup(self, first_ltrs):
self.page2 = Selectable.Repository(nb, -1, first_ltrs)
self.nb.AddPage(self.page2, "Patient Lookup")
self.page2.SetFocus()
