While doing some activities to learn python/tkinter, I've faced this problem:
-I want to make a visible countdown in a specific screen (1280x720), but I can't make it work if I remove the 10th line from the following code, which is causing a second window to open:
from future.moves import tkinter
top=tkinter.Tk()
HEIGHT=720
WIDTH=1280
canvas = tkinter.Canvas(top, height=HEIGHT, width=WIDTH)
canvas.pack()
class Tempo(tkinter.Tk):
def __init__(self):
tkinter.Tk.__init__(self)
self.label = tkinter.Label(top,width=10, font="Verdana 12 bold",bg="white")
self.label.place(relwidth=0.18,relheight=0.04,relx=0.5-0.09,rely=0.3-0.02)
self.remaining = 0
self.countdown(10)
def countdown(self, remaining = None):
if remaining is not None:
self.remaining = remaining
if self.remaining <= 0:
self.label.configure(text="time's up!")
else:
self.label.configure(text="%d" % self.remaining)
self.remaining = self.remaining - 1
self.after(1000, self.countdown)
tempo=Tempo()
tempo.countdown()
top.mainloop()
How can I make it work properly?
The source from the code I'm using: Making a countdown timer with Python and Tkinter?
