[Tutor] CheckButtons reset to default values

[Pooja Bhalode]

Hi Peter,

The code is as shown below.  I have put it in the manner you have told me.

root = Tk()
root.title("Design of Experiments with Parameter Estimation")
root.geometry("1000x1000")

def DesignPoint():
    print "Inside Design Point"
    rootdesign=Tk()
    rootdesign.title("Estimation of Experimental Precision for Data
Var-CoVar")
    rootdesign.geometry("600x400")
    frame1 = Frame(rootdesign)
    frame1.grid(row=0, column=0)

    ## Inserting Checkboxes:
    label1 = Label(frame1, text="1. Design Point Suggestions")
    label1.grid(row=0, column=0,sticky=W )
    var1 = IntVar()
    var2 = IntVar()
    var3 = IntVar()
    var4 = IntVar()
    Checkbutton(frame1, text = "Vertices", variable=var1, onvalue=1,
offvalue=0).grid(row=1, column = 1, sticky=W)
    Checkbutton(frame1, text = "Edges", variable=var2).grid(row=2, column =
1, sticky=W)
    Checkbutton(frame1, text = "Faces", variable=var3).grid(row=3, column =
1, sticky=W)
    check = Checkbutton(frame1, text = "Center", variable=var4)
    check.grid(row=4, column = 1, sticky=W)
    check.select()


    label2 = Label(frame1, text="2. Cut off Improvement %")
    label2.grid(row=5, column=0,sticky=W)
    Entry2 = Entry(frame1)
    Entry2.insert(END, '05')
    Entry2.grid(row=5, column = 1, sticky = W)

    label3 = Label(frame1, text="3. Simulation of proposed Experiments: ")
    label3.grid(row=5, column=0,sticky=W)

    label4 = Label(frame1, text="4. Calculate sensitivities")
    label4.grid(row=6, column=0,sticky=W)

    def default():
        print "Inside default"

        var1.set(0)
        var2.set(0)
        var3.set(0)
        var4.set(1)
        Entry2.delete(0, END)
        Entry2.insert(END,'05')
   Button(frame1, text = "Select Default value",
command=default.grid(row=0, column = 2, sticky=W)

    rootdesign.mainloop()


## Secondary menu bar:
menusec = Frame(root, bg="white")
butt1 = Button(menusec, text="Part One", command=DesignPoint)
butt1.pack(side=LEFT, padx=1)
menusec.pack(side=TOP, fill=X)


root.mainloop()

It still doesn't work for me for the reason I am not able to figure out.
Please let me know.
Thank you once again in advance.

Pooja
