tkinter python maximize window
If you want to set the fullscreen attribute to True, it is as easy as:
root = Tk()root.attributes('-fullscreen', True)However, it doesn't show the title bar. If you want to keep it visible, you can resize the Tk element with the geometry() method:
root = Tk()w, h = root.winfo_screenwidth(), root.winfo_screenheight()root.geometry("%dx%d+0+0" % (w, h))With winfo_width() and winfo_height() you can get the width and height or the window, and also you can bind an event handler to the <Configure> event:
def resize(event): print("New size is: {}x{}".format(event.width, event.height))root.bind("<Configure>", resize)
To show maximized window with title bar use the 'zoomed' attribute
root = Tk()root.attributes('-zoomed', True)
