Python 3.x - toggling fullscreen in tkinter
not sure why it isn't working on your computer, but try this code sample:
#!python3import tkinter as tkgeom=""def fullscreen(): global geom geom = root.geometry() w = root.winfo_screenwidth() h = root.winfo_screenheight() root.overrideredirect(True) root.geometry('%dx%d+0+0' % (w, h))def exitfullscreen(): global geom root.overrideredirect(False) root.geometry(geom)root = tk.Tk()tk.Button(root,text ="Fullscreen", command=fullscreen).pack()tk.Button(root,text ="Normal", command=exitfullscreen).pack()root.mainloop()the one thing i'm making sure i do is to store the geometry before going fullscreen, and then re applying it when i exit fullscreen. the global statement was needed because if i didn't use it the fullscreen function stored the geometry in a local variable instead of the one i created at the top.
Change the overrideredirect flag before calling withdraw and deiconify.
