Tkinter
has this method:
window_name.attributes('-fullscreen',True)
and customtkinter
?
I haven't found anything but
geometry(f"{WIDTH}x{HEIGHT}")
However when I grab screen size and put as WIDTH & HEIGHT the screen does change the size but does not go full size, I mean it is always shifted to the right so the windows leaves the margin on the left and top and the part of the window goes out of the screen to the right.
