This article focus on creating a stopwatch using Tkinter in python
Tkinter : Tkinter is the standard GUI library for
Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. It’s very easy to get started with Tkinter, here are some sample codes to get your hands on Tkinter in python.
Python3
import tkinter
top = tkinter.Tk()
top.mainloop()
Output:
Creating Stopwatch using Tkinter
Now lets try to create a program using Tkinter module to create a stopwatch.
A stopwatch is a handheld
timepiece designed to measure the amount of time elapsed from a particular time when it is activated to the time when the piece is deactivated. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stop clock. In manual timing, the clock is started and stopped by a person pressing a button. In fully automatic time, both starting and stopping are triggered automatically, by sensors.
Required Modules: We are only
going to use Tkinter for creating GUI and no other libraries will be used in this program.
Source Code:
Python3
import tkinter as Tkinter
from datetime import datetime
counter = 66600
running = False
def counter_label(label):
def count():
if running:
global counter
if counter==66600:
display="Starting..."
else:
tt = datetime.fromtimestamp(counter)
string = tt.strftime("%H:%M:%S")
display=string
label['text']=display
label.after(1000, count)
counter += 1
count()
def Start(label):
global running
running=True
counter_label(label)
start['state']='disabled'
stop['state']='normal'
reset['state']='normal'
def Stop():
global running
start['state']='normal'
stop['state']='disabled'
reset['state']='normal'
running = False
def Reset(label):
global counter
counter=66600
if running==False:
reset['state']='disabled'
label['text']='Welcome!'
else:
label['text']='Starting...'
root = Tkinter.Tk()
root.title("Stopwatch")
root.minsize(width=250, height=70)
label = Tkinter.Label(root, text="Welcome!", fg="black", font="Verdana 30 bold")
label.pack()
f = Tkinter.Frame(root)
start = Tkinter.Button(f, text='Start', width=6, command=lambda:Start(label))
stop = Tkinter.Button(f, text='Stop',width=6,state='disabled', command=Stop)
reset = Tkinter.Button(f, text='Reset',width=6, state='disabled', command=lambda:Reset(label))
f.pack(anchor = 'center',pady=5)
start.pack(side="left")
stop.pack(side ="left")
reset.pack(side="left")
root.mainloop()
