Modules in wxPython
I am not sure how to make modules in wxpython, I can do it Python, but for some reason I'm getting a lot of problems when I try to do it in wxPython.
I made a very simple code using to files (test.py and test2.py). The is test.py: Code:
from wxPython.wx import *
from test2
class MainWindow(wxFrame):
def __init__(self,parent,id,title):
wxFrame.__init__(self,parent,wxID_ANY, title, size = (200,100))
EVT_LEFT_DOWN(self,test2.OnClick)
self.Show(true)
app = wxPySimpleApp()
frame = MainWindow(None, -1, "Hello")
app.MainLoop()
and this is test2.py: Code:
from wxPython.wx import *
def OnClick(event):
text1 = wxStaticText(self, -1, "HJJJJJJJ", (100,100))
Show.text1(true)
This is the error get when I open run the file in idle: Code:
Traceback (most recent call last):
File "C:\Documents and Settings\inuk\Desktop\Tweaks\Program\test.py", line 13, in ?
frame = MainWindow(None, -1, "Hello")
File "C:\Documents and Settings\inuk\Desktop\Tweaks\Program\test.py", line 8, in __init__
EVT_LEFT_DOWN(self,test2.OnClick)
AttributeError: 'module' object has no attribute 'OnClick'
I'm a beginner, so I'm pretty sure this is simple to solve. So if anybody can help me that would be great.

I can't believe I did that, but I still have problems even though i fixed that.
so test.py is now: Code:
from wxPython.wx import *
import test2
class MainWindow(wxFrame):
def __init__(self,parent,id,title):
wxFrame.__init__(self,parent,wxID_ANY, title, size = (200,100))
EVT_LEFT_DOWN(self,test2.OnClick)
self.Show(true)
app = wxPySimpleApp()
frame = MainWindow(None, -1, "Hello")
app.MainLoop()
but i still get an error: Code:
Traceback (most recent call last):
File "C:\Documents and Settings\inuk\Desktop\Tweaks\Program\test2.py", line 4, in OnClick
text1 = wxStaticText(self, -1, "HJJJJJJJ", (100,100))
NameError: global name 'self' is not defined
I've tried leaving the Parent section blank or with "none", but that doesn't work. I'm not sure exactly what to place instead of "self" or what I have to change to make "self" work, if i need to use the word "self" in the parent section.

Your test2.OnClick event handler is not part of a class instance. self gets defined for you when an instance of a class is created but its scope is limited to the instance (if you have lots of class instances which self would be the right self in a global context
 . Methods of a class instance can use the self variable that was auto generated but normal functions wont know what it is grimey

Generally you would put the OnClick handler back into the main window class since it is a normally considered a method of that class and not a seperate thing at all. There is nothing to stop the handler being a wrapper to the real code in another module but if as you have it the code you want executed is managing the window that gets messy.
Code:
def ....(self,...): #Some init method you call before the window is displayed
self.text1 = wxStaticText(self, -1, "", (100,100))
self.text1.Show(False)
def OnClick(self, event):
self.text1.SetLabel("Blah!!!")
self.text1.Show(True)
...
anotherModule.actionCode(some paramter)
