Question

I’m not sure on how to articulate this…

I have a Tkinter window, and I need to hide half of this window when a button is pressed.
However, I need the left-most side to be hidden, so that the window is now half the size it originally was,
and shows the right half of the original window.

All of Tkinter’s resize functions span from the left side of the window.
Changing the geometry values can only show the left side whilst hiding the right;
I need the inverse.

Does anybody know how to go about doing this?

(I don’t want the user to have to drag the window border,
I need the button to automate it).

Answer 1

does this do what you want ?

import Tkinter as Tk #tkinter

def toggle():
    if frame1.winfo_ismapped():
        frame1.grid_remove()
    else:
        frame1.grid()

root = Tk.Tk()
root.geometry('-450+250')
frame1 = Tk.Frame(root, width=200, height=100, bg='red')
frame1.grid(row=0, column=0)
frame2 = Tk.Frame(root, width=200, height=100, bg='blue')
frame2.grid(row=0, column=1)
Tk.Button(root, text='toggle', command=toggle).grid(row=1, column=1)

root.mainloop()
