Question

In the following code, I have been trying to disable the entry1 widget every time I select 1 in the combobox and disable entry2 when i select 2 in combobox.

this is my code:

from Tkinter import *
import ttk

def refresh():
    if v.get() == 'A':
        entry1.state(['disabled'])
        entry2.state(['!disabled'])
    elif v.get() == 'B':
        entry2.state(['disabled'])
        entry1.state(['!disabled'])




root = Tk()
v = StringVar()
var = StringVar()

entry1 = ttk.Entry (root, textvariable= var)
entry1.grid(row=2, column=2, sticky=(E,W))

entry2 = ttk.Entry (root, textvariable= var)
entry2.grid(row=4, column=2, sticky=(E,W))


v_list=['A','B']
v.set(v_list[1])
v_optionmenu = apply(OptionMenu, (root,v) + tuple(v_list))
v_optionmenu.grid(column=4,row=11,sticky=(W,E))

var = v
root.bind('<Return>', lambda e: refresh)

root.mainloop()

I wanted to create condition based enabling and disabling of widgets.
My conditions usually are:

selection in combobox
Selection of radiobutton

Please Advice how i can go about it.

def refresh(*args):

    if  v.get() == 'Disable' :
        fb_entry.state(['disabled'])
        fw_entry.state(['disabled'])
        fb.set('')
        fw.set('')
    elif v.get() == 'Enable' :
        fb_entry.state(['!disabled'])
        fw_entry.state(['!disabled'])


root = Tk()
v = StringVar()
var = StringVar()

entry1 = ttk.Entry (root, textvariable= var)
entry1.grid(row=2, column=2, sticky=(E,W))

entry2 = ttk.Entry (root, textvariable= var)
entry2.grid(row=4, column=2, sticky=(E,W))


v_list=['Disable','Enable']
v.set(v_list[1])
v_optionmenu = apply(OptionMenu, (root,v) + tuple(v_list))
v_optionmenu.grid(column=4,row=11,sticky=(W,E))

var = v

root.bind('<Enter>',refresh_widget)
root.mainloop()
