I'm new to programming and new to Python; namespace issues are getting
the best of me. Can someone help me with the following:
import wx
import sys
sys.path.append('~/PyPrograms/EMRGUI')
import Selectable
class MyApp(wx.App):
def __init__(self):
wx.App.__init__(self)
frame = MyFrame(None, -1, 'EMR') #create instance of
MyFrame
frame.Show(True) #make visible and
center frame
frame.Centre()
class MyFrame(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(600,500))
nb = wx.Notebook(self) #create instance of
wx.Notebook
self.page1 = Form1(nb, -1) #create instance of
panel Form1 with
Notebook instance as parent
nb.AddPage(self.page1, "Choose Patient") #add the panels as
Notebook
pages
self.page1.SetFocus() #give focus to page 1
def patient_lookup(self, first_ltrs): #passes first letters of
last name and creates new page c results
self.page2 = Selectable.Repository(nb, -1, first_ltrs) #creates
instance of panel Repository from Selectable mod
nb.AddPage(self.page2, "Patient Lookup") #adds second page with
results
self.page2.SetFocus() #give focus to new page
class Form1(wx.Panel):
def __init__(self, parent, id):
wx.Panel.__init__(self, parent, id) #inherits from wx.Panel
f = wx.GetTopLevelParent(self)
self.button = wx.Button(self, 10, "Search", wx.Point(200,
325)) #create instance of wx.Button
wx.Button.SetTransparent(self.button, 100)
#experiment with
SetTransparent method
self.lblname = wx.StaticText(self, -1, "Enter first letters of
last name:",wx.Point(20,60))
self.editname = wx.TextCtrl(self, 20, "", wx.Point(150, 60),
wx.Size(140,-1))
wx.EVT_BUTTON(self, 10, f.patient_lookup(self.editname.Value))
#calls function to get list of patients
app = MyApp() #create instance of
MyApp
app.MainLoop() #run program
I'm getting an error from the patient_lookup function: "global name
'nb' is not defined". I don't understand how a function in the same
class cannot see the wx.Notebook instance "nb". I know it exists
somewhere I just haven't found the name for it. I've tried
"frame.nb", "self.nb", f = GetTopLevelParent(self) then f.nb. How can
an instance of something just disappear?
Thanks for any help.
Mike
