Python GUI/tk

[Ash.Shuklaa at googlemail.com]

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()
