问题
i have a project that i am working on for class and i am using tkinter to build my basic GUI. when i run the code i have two drop down menus to choose options from. i also want a button to close the window and advance the program to the next GUI window. however i can not get a button to close the window without also causing the program to terminate. here is my code
from tkinter import *
Options_year = ["2014", "2013", "2012", "2011", "2010"]
Options_month = ["January","February", "March", "April","May", "June", "July","August","September","October","November",
"December"]
master = Tk()
variable_year = StringVar(master)
variable_year.set(Options_year[0])
variable_month = StringVar(master)
variable_month.set(Options_month[0])
window = apply(OptionMenu, (master, variable_year) + tuple(Options_year))
window_month = apply(OptionMenu, (master,variable_month) + tuple(Options_month))
window.pack()
window_month.pack()
button = Button(master, text = "Continue", command = master.quit())
#the line above is the button that i want to use to close the window
button.pack()
mainloop()
print (variable_month.get())
print (variable_year.get())
EDIT: converted this to a frame and used the supplied answer below and got it to work. thanks to every one who helped me
回答1:
Use a Toplevel or frame, put the widgets in it, and destroy() it. You can use master.withdraw() or iconify() if you do not want it to show.
回答2:
Destroying the gui also destroys tk Variables. I strongly suspect that you omitted the vital information that the program terminates with a exception traceback due to the attempt to access the .get method of the non-longer existent variable_month. The following works fine.
from tkinter import *
root = Tk()
root.mainloop()
print('here')
