Tkitner ttk Progressbar options orient, length(),mode(),maximum(),value(),variable()

Tkinter Progressbar to show status with options and methods to manage and display values

We used two buttons b1 and b2 to execute our function my_fun() on click event. This function my_fun() receives one parameter whose value is based on which button is clicked.

Inside the function the option value data is incremented or decremented based on the input parameter type and the text option of Label is updated using config().
Full code is here

import tkinter  as tk 
from tkinter import *
from tkinter import ttk
my_w = tk.Tk()
my_w.geometry("400x200")  

def my_fun(type): # update the value of progress bar 
    if(type=='+'): 
        prg1['value'] += 10 # increase value 
    else:
        prg1['value'] -= 10 # decrease value    
    l1.config(text=str(prg1['value'])) #update Label

prg1 = ttk.Progressbar(my_w,orient = HORIZONTAL,
              length = 300, mode = 'determinate')
prg1.place(relx=.1,rely=.3)    

b1=tk.Button(my_w,text='Move +',command=lambda: my_fun('+'))
b1.place(relx=0.3,rely=0.5)

b2=tk.Button(my_w,text='Move -',command=lambda: my_fun('-'))
b2.place(relx=0.5,rely=0.5)

font1=('times',24,'normal')
l1=tk.Label(my_w,text='value here',font=font1)
l1.place(relx=0.4,rely=0.01)

my_w.mainloop()  # Keep the window open

We used the following options of progress bar

mode

In the above code change the progress bar option mode to indeterminate

prg1 = ttk.Progressbar(my_w,orient = HORIZONTAL,
              length = 300,  mode = 'indeterminate')

Option value and variable

By using value option we can set and read the data of the progress bar. By using vriable option we can connect ( or update ) this data to another variable.
Check below how the value of String Variable x is used to display the data in a Label. The data associated with x is taken from the Progress bar by using the option variable
start() step() and stop() Method example

Here is a list of all options of Progressbar

Options	Details
orient	Orientation of the Progress bar. Values are Horizontal or Vertical
length	Length of the Progress bar, (width if horizontal, height if vertical)
mode	Values can be determinate OR indeterminate Check the examples
maximum	Default value is 100, specifies the maximum value.
value	The current value of the Progress bar. Can be set or read.
variable	Variable can be linked to value of Progress Bar. Realtime changes ( in values ) can be captured.

Progressbar stopping at maximum and minimum value

In the above code, change the function my_fun() like this by adding conditions. To go beyond 100 the current value must be below 100. Similarly to go below 0 the existing value must be higher than 0.

def my_fun(type): # update the value of progress bar 
    if(type=='+' and prg1['value']<100): # Upper limit is 100 
        prg1['value'] += 10 # increase value 
    elif(type=='-' and prg1['value']>0): # Lower limit is 0
        prg1['value'] -= 10 # decrease value    
    l1.config(text=str(prg1['value'])) #update Label

Close the window once the value reached maximum value

def my_fun(type): # update the value of progress bar 
    if(type=='+' and prg1['value']<100): # Upper limit is 100 
        prg1['value'] += 10 # increase value 
    elif(type=='-' and prg1['value']>0): # Lower limit is 0
        prg1['value'] -= 10 # decrease value    
    l1.config(text=str(prg1['value'])) #update Label
    if prg1['value']==prg1['maximum']:
        my_w.destroy()

import tkinter  as tk 
from tkinter import *
from tkinter import ttk
my_w = tk.Tk()
my_w.geometry("400x200")  

def my_fun(type): # update the value of progress bar 
    if(type=='+' and prg1['value']<100): # Upper limit is 100 
        prg1['value'] += 10 # increase value 
    elif(type=='-' and prg1['value']>0): # Lower limit is 0
        prg1['value'] -= 10 # decrease value    
    l1.config(text=str(prg1['value'])) #update Label
    if prg1['value']==prg1['maximum']:
        my_w.destroy()

prg1 = ttk.Progressbar(my_w,orient = HORIZONTAL,
              length = 300, mode = 'determinate',maximum=100)
prg1.place(relx=.1,rely=.3)    

b1=tk.Button(my_w,text='Move +',command=lambda: my_fun('+'))
b1.place(relx=0.3,rely=0.5)
