Hello, I am a total beginner with python and tkinter and I am having a hard time getting my program working, I think the problem come from passing variables. I would like to have a menu that would with three main buttons, the first one (LUT) let me chosse between two files, the second button (rrs) opens a browser to choose a file and the third button would run a program (or function) that makes some computation between the two files open with button 1 and button 2, Here is what I have written
from Tkinter import * from tkFileDialog import askopenfilename import numpy as np class openfile(): def __init__(self, yn): if yn == 0 : self.lut = np.loadtxt("C:\python26\LUTnpdi_chile",dtype=np.float,skiprows=1) if yn == 1 : self.lut = np.loadtxt("C:\python26\LUTnpdi_nwa",dtype=np.float,skiprows=1) if yn == 2 : filename = askopenfilename(filetypes=[("allfiles","*"),("pythonfiles","*.py")]) if yn == 2 : self.lut = np.loadtxt(filename,dtype=np.float,skiprows=1) Class rrs_file(self,rrs): filename = askopenfilename(filetypes=[("allfiles","*"),("pythonfiles","*.py")]) rrs = np.loadtxt(filename,dtype=np.float,skiprows=1) def make_comp(): result = self.lut[1,2] * rrs[1,2] print result def callback(): print "called the callback!" root = Tk() # create a menu menu = Menu(root) root.config(menu=menu) filemenu = Menu(menu) menu.add_cascade(label="LUT", menu=filemenu) filemenu.add_command(label="East Pacific", command=lambda:openfile(0)) filemenu.add_command(label="NW Atlantic", command=lambda:openfile(1)) image_menu = Menu(menu) menu.add_cascade(label="Rrs", command=rrs_file) run_menu = Menu(menu) menu.add_cascade(label="Run", command = make_comp) quitmenu = Menu(menu) menu.add_cascade(label="Quit", command=root.destroy) #x = openfile(2) mainloop() I can not figure out how to pass get the lut and rrs parameters that I have defined in the class objects? I need help !!! Thank you very much in advance. Emmanuel
