Hello,
I'm still learning how to call class methods from other classes. I'm trying to figure out what is the best approach to executing a Tkinter UI from another class. It tells me that it expects two aurguments but received only 1. I expect it may have something to do with "app = App(root)" from class1.py.
I also tried defining another procedure that would execute both but I'm still confused.
Thanks for the help!
Frank
For example: -
Class1.py
-
-----------------------------------------------
-
import Tkinter
-
-
-
class App(Frame):
-
def __init__(self , master):
-
Frame.__init__(self, master)
-
-
def makeFrames(self):
-
code
-
def makeRest(self):
-
code
-
def gerChars(self):
-
code
-
-
def createUI(self):
-
#creates the UI
-
self.makeFrames()
-
self.makeRest()
-
self.gerChars()
-
-
root = Tk()
-
app = App(root)
-
app.pack()
-
app.createUI()
-
root.mainloop()
-
-
-------------------------------------------------------
-
Class2.py calling class1.py to execute UI
-
-
-
import class1
-
-
class ImportChar:
-
def __init__(self):
-
app = App(root)
-
-
def AppendChar(self):
-
code
-
-
def RunItAll(self):
-
self.ApppendChar()
-
self.app.createUI()
-
-
importchar = ImportChar()
-
importchar.RunItAll()
-
-
-
-------------------------------------------------

I like to teach OOP (especially GUI OOP) in terms of "it" and "has a".
An application has a main frame.
An application has a main loop.
The main frame has a user interface (many widgets).
The main frame has a worker class.
In those terms, the modules would lay out like this
Class1.py - # Don't need much from Tkinter to make an app
-
from Tkinter import Tk
-
-
# in the module that defines App, import the frames that belong to it
-
import Class2
-
-
class App: # not sure if there's a good super class in Tkinter
-
def __init__(self, root):
-
self.mainFrame = Class2.MainFrame(root)
-
self.mainFrame.pack()
-
-
-
-
if __name__ == "__main__":
-
root = Tk() # This is the actual Tkinter app level object
-
app = App(root)
-
root.mainloop()
-
Class2.py - # I don't like import *, but...
-
from Tkinter import *
-
-
# Support Classes # Even better in another module
-
-
class Worker:
-
-
def AppendChar(self, data):
-
# code
-
print "Appending Chars", data
-
-
-
-
# The main frame is in charge of all object creation #
-
-
class MainFrame(Frame):
-
def __init__(self , master):
-
Frame.__init__(self, master)
-
self.createUI
-
-
def createUI(self):
-
#creates the UI
-
self.makeFrames()
-
self.makeRest()
-
self.gerChars()
-
-
def makeFrames(self):
-
# code
-
print "Making Frames"
-
-
def makeRest(self):
-
self.woker = Worker()
-
print "Making Rest"
-
-
# event handlers #
-
-
def gerChars(self):
-
# code
-
print "Getting Chars"
-
-
def OnReasonToAppendChars(self):
-
self.worker.AppendChars("abcd")
-
Then, simply running the Class1.py module creates the whole app.
If you really want an application object, it would look like this: - # Don't need much from Tkinter to make an app
-
from Tkinter import Tk
-
-
# in the module that defines App, import the frames that belong to it
-
import Class2
-
-
class App(Tk):
-
def __init__(self, **kwargs):
-
Tk.__init__(self, **kwargs)
-
self.mainFrame = Class2.MainFrame(self)
-
self.mainFrame.pack()
-
-
-
-
if __name__ == "__main__":
-
app = App(className='MyAppClass')
-
app.mainloop()
-
