Question

I’m currently working on a project using the Tkinter module in Python. I am using the menu widget and for each command on the menu there is another command associated with it. Each of these commands opens a new frame. I am using the grid geometry manager.

My problem is that I would like the user to be able to switch from frame to frame but when I try doing this, the frames overlap each other instead of switching. How can I get the active frame to hide and then open up a new frame? I don’t want to have to iterate through a list of possible frames and tell them all to hide.

Here is the code I’ve written so far:

import Tkinter as tkinter
root = tkinter.Tk()
root.minsize(400,300)
welcome = tkinter.Frame(root).grid()
label = tkinter.Label(welcome, text="Welcome to my program").grid(row=0, column=3)
button = tkinter.Button(welcome,text="Exit",command=root.destroy).grid(row=3, column=1)
def newFrame():
        newFrame = tkinter.Frame(root).grid()
        newFrame_name = tkinter.Label(newFrame, text="This is another frame").grid()
menu = tkinter.Menu(root)
root.config(menu=menu)

main_menu = tkinter.Menu(menu)
menu.add_cascade(label="Main Menu", menu= main_menu)
main_menu.add_command(label="New Frame", command=newFrame)

#menu.add_command(label="Exit", command=root.destroy, menu= filemenu)


root.mainloop()

When the user selects the New Frame option from the menu, I want the newFrame to replace the welcome frame.

If you use place or grid to stack the frames on top of each other you can simply change the stacking order with the lift method.
