Tkinter: Labels

Label is simple think to display view only data
With label you can not interact
Mainly two type of labels
1. text label
2. image label

Use of normal Lable

from tkinter import *

root = Tk()

w = Label(root,
          text="Hello Tkinter")

w.pack()

.pack() method tell Tk to fit the size of window to the given text

# ending mainloop
root.mainloop()

Dynamcally change the Label Value

from tkinter import *

root = Tk()

root.title("Drynamic Label")

''

def stop():
    root.destroy()

c=0

def start():
    def count():
        global c
        c+=1
        w.config(text=str(c))
        w.after(100,count)
    count()

w = Label(root, justify=CENTER)
w.pack()

justify options are : LEFT, RIGHT, CENTER

start()

b= Button(root, text="Stop", command = stop)
b.pack()

root.mainloop()

Use Image as Label

from tkinter import *

root = Tk()

logo = PhotoImage(file="Images/tk.png")

Some formates will not support by PhotoImage then you have to workaround

w = Label(root,
         image=logo)
w.pack()

root.mainloop()

Applying Color and diffrent Font to Label

from tkinter import *

root = Tk()

data = "Python Pune"

w = Label(root,
         fg='white',
         bg='black',
         text=data,
         font=("Helvetica", 16)
)
w.pack()

root.mainloop()
