I am ne to python GUi, I have built a cust frame by inheriting the Frame ,
the code is as follows :
from Tkinter import *
from logging import exception
import tkFileDialog
import pickle
import os.path
STATION_NAME, TARGET_NAME, HOST_NAME, TARGET_IP, HOST_IP, EXCEL_FILE =
range(6)
class NAddStation(Frame):
def __init__(self, parent=None):
Frame.__init__(self, parent)
self.pack(side=TOP, expand=YES, fill=BOTH)
self.tempVar = []
# Label Area
self.labels = ["Station Name :", "Target Name :", "Host Name
:", "Target's IP :", "Host's IP :",
"Excel File :"]
self.REMOVE =1
self.ADD = 2
self.UPDATE = 3
# Entry Area
self.Entry_Target_Name = None
self.Entry_Host_Name = None
self.Entry_Target_IP = None
self.Entry_Host_IP = None
self.Entry_Station_Name = None
self.Entry_File_Path = None
#Misc
self.File_Browse_Button = None
self.Add_Button = None
self.Cancel_Button = None
self.createWindow()
def openFileBrowser(self):
filepath = tkFileDialog.askopenfilename()
self.Entry_File_Path.insert(0, filepath)
def validate(self):
print("Adding Data....")
self.Store_Station()
def Remove_Station(self,key):
if os.path.isfile('Station-pickle'):
dbfile = open('Station-pickle', 'rb')
db = pickle.load(dbfile)
dbfile.close()
db.__delitem__(key)
dbfile = open('Station-pickle', 'wb')
pickle.dump(db, dbfile)
dbfile.close()
def returnStationName(self):
return self.tempVar[0].get()
def Store_Station(self):
fl={}
rc={}
fl['SN']= self.tempVar[0].get()

station_name = self.tempVar[0].get()
rc[station_name]= fl
if not os.path.isfile('Station-pickle'):
print ("Creating File")
dbfile = open('Station-pickle', 'wb') # use
binary mode files in 3.X
pickle.dump(rc, dbfile) # data is
bytes, not str
else:
print ("Appending File")
# --------

dbfile.close()
dbfile.close()
def Load_Station(self, key_value):
dbfile = open('Station-pickle', 'rb') # use binary
mode files in 3.X
db = pickle.load(dbfile)
for key in db:
if key == key_value:
print("STATION_NAME :" + db[key]['SN'])
print("HOST_NAME :" + db[key]['HN'])
print("HOST_IP :" + db[key]['HP'])

**Now I want to use the above mentioned Custom Frame in Main app , when i
ckick on AddStation from menu file the custome Frame pops up , I can add
the data but when i click on ok , i want the data to apear on the textArea ,
