Python GUI Tk : Label

 Label width and height

from Tkinter import *
root = Tk()
labelfont = ('times', 20, 'bold')                  
widget = Label(root, text='Hello config world')
widget.config(height=3, width=20)
widget.pack(expand=YES, fill=BOTH)
root.mainloop()

A label and a button

import sys, Tkinter
Tkinter.Label(text="Welcome!").pack()
Tkinter.Button(text="Exit", command=sys.exit).pack()
Tkinter.mainloop()

Basic coding styles with labels

from Tkinter import Label                               
widget = Label(None, text='Hello GUI world!')           
widget.pack()                                           
widget.mainloop()

Set side to top

from Tkinter import *
root = Tk() 
Label(root, text='Hello GUI world!').pack(side=TOP) 
root.mainloop()

Add a label to a frame

from Tkinter import *

root = Tk()
root.title("Labeler")
root.geometry("200x500")

app = Frame(root)
app.grid()

lbl = Label(app, text = "I'm a label!")
lbl.grid()

root.mainloop()

Load image to label

from Tkinter import *

root = Tk()
#root.option_readfile('optionDB')
root.title('Labels')
Label(root, text="Text ", wraplength=300, justify=LEFT).pack(pady=10)
f1=Frame(root)
Label(f1, text="Text", relief=RAISED).pack(side=LEFT, padx=5)
Label(f1, text="Text", relief=SUNKEN).pack(side=LEFT, padx=5)
f1.pack()
f2=Frame(root)
for bitmap,rlf  in [('woman', RAISED),('mensetmanus',SOLID),('terminal',SUNKEN),
               ('escherknot',FLAT),('calculator',GROOVE),('letters',RIDGE)]:
    Label(f2, bitmap='@bitmaps/%s' % bitmap, relief=rlf).pack(side=LEFT, padx=5)
f2.pack()
root.mainloop()

Label wraplength

from Tkinter import *

root = Tk()
#root.option_readfile('optionDB')
root.title('Labels')
Label(root, text="Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text ", wraplength=300, justify=LEFT).pack(pady=10)
f1=Frame(root)
Label(f1, text="Text", relief=RAISED).pack(side=LEFT, padx=5)
Label(f1, text="Text", relief=SUNKEN).pack(side=LEFT, padx=5)
f1.pack()
f2=Frame(root)
for bitmap,rlf  in [('woman', RAISED),('mensetmanus',SOLID),('terminal',SUNKEN),
               ('escherknot',FLAT),('calculator',GROOVE),('letters',RIDGE)]:
    Label(f2, bitmap='@bitmaps/%s' % bitmap, relief=rlf).pack(side=LEFT, padx=5)
f2.pack()
root.mainloop()

Set text and font for Label

from Tkinter import *
import math

root = Tk()              
top = Frame(root)        
top.pack(side='top')     

hwframe = Frame(top)
hwframe.pack(side='top', anchor='w')
font = 'times 18 bold'
hwtext = Label(hwframe, text='Hello, World!', font=font)
hwtext.pack(side='top', pady=20)

rframe = Frame(top)
rframe.pack(side='top', padx=10, pady=20, anchor='w')
r_label = Label(rframe, text='The sine of')
r_label.pack(side='left')
r = StringVar() 
r.set('1.2')    
r_entry = Entry(rframe, width=6, textvariable=r)
r_entry.pack(side='left')

s = StringVar() 
def comp_s(event):
    global s
    s.set('%g' % math.sin(float(r.get()))) # construct string

r_entry.bind('<Return>', comp_s)

compute = Label(rframe, text=' equals ')
compute.pack(side='left')

s_label = Label(rframe, textvariable=s, width=12)
s_label.pack(side='left')

def quit(event=None):
    root.destroy()

quit_button = Button(top, text='Goodbye, GUI World!', command=quit,
                     background='yellow', foreground='blue')
quit_button.pack(side='top', pady=5, ipadx=30, ipady=30, anchor='w')

root.bind('<q>', quit)

root.mainloop()

Label(frm, text="Label").pack()
canvas.create_window(285, 280, window=frm, anchor=CENTER)

canvas.pack()
