Python GUI/tk

A

Ash.Shuklaa

Hi,

I am making a GUI with the help of python.In the program, when "ADD"
button is pressed new frames build up and when you press "delete"
button those frames will be destroyed . My problem is that these frames
only get destroyed in Tk but the data structure associated with it (in
Python) doesn't change.


#!/usr/bin/python
from Tkinter import*

class Frame_1(LabelFrame):
def __init__(self,master):
LabelFrame.__init__(self,master)
self.configure(text="Frame1")
self.grid()

def control_buttons(self,frame):
Button( self, text = "Add", command = frame.add_button ).grid(
)
Button( self, text = "Read", command = frame.read_button
).grid()

class Frame_2(LabelFrame):
def __init__(self,master):
LabelFrame.__init__(self,master)
self.configure(text ="Frame2")
self.grid()
self.sub_frame = []

def add_button(self):
new_frame = Frame_2_1(self)
# new_frame.grid()
new_frame.populate()
self.sub_frame.append(new_frame)
# print self.sub_frame

def read_button(self):
print "#"*10
for sub_frame in self.sub_frame :
print "-"*30
print "band:"+ sub_frame.band.get()
print "channel:" + sub_frame.channel.get()

class Frame_2_1(LabelFrame):
def __init__(self,tkmaster):
LabelFrame.__init__(self,tkmaster)
self.configure(text ="DEFAULT")
self.grid()

def populate(self):
self.band = StringVar()
self.band.set("900")
option = OptionMenu(self, self.band,"900","1800","1900"
).grid()

self.channel = StringVar()
self.channel.set("CS 1")
option = OptionMenu(self,self.channel,"CS 1","CS 2","CS 3","CS
4").grid( )

global temp
temp= temp+1
Button(self,text = "Remove"+ str(temp),command=
self.delete_frame).grid()


def delete_frame(self):
self.destroy()

root = Tk()
temp=-1
# Create frame 1
frame_1 = Frame_1(root)
# Create frame 2
frame_2 = Frame_2(root)

frame_1.control_buttons(frame_2)
root.mainloop()
