Requisitos previos: Introducción a tkinter | Programa para calcular GST
Python ofrece múltiples opciones para desarrollar una GUI (Interfaz gráfica de usuario). De todos los métodos GUI, Tkinter es el método más utilizado. En este artículo, aprenderemos cómo crear una aplicación GUI de GST Rate Finder usando Tkinter, con una guía paso a paso.
Para crear un Tkinter:
- Importando el módulo – tkinter
- Crear la ventana principal (contenedor)
- Agregue cualquier cantidad de widgets a la ventana principal.
- Aplique el evento Trigger en los widgets.
A continuación se muestra cómo se verá la GUI:
Vamos a crear una aplicación GST Rate Finder basada en GUI:
A continuación se muestra la implementación:
Python3
# import all functions/classes from the tkinter
from tkinter import *
# Function for finding GST rate
def findGst() :
# take a value from the respective entry boxes
# get method returns current text as string
org_cost= int(org_priceField.get())
N_price = int(net_priceField.get())
# calculate GST rate
gst_rate = ((N_price - org_cost) * 100) / org_cost;
# insert method inserting the
# value in the text entry box.
gst_rateField.insert(10, str(gst_rate) + " % ")
# Function for clearing the
# contents of all text entry boxes
def clearAll():
# deleting the content from the entry box
org_priceField.delete(0, END)
net_priceField.delete(0, END)
gst_rateField.delete(0, END)
# Driver Code
if __name__ == "__main__" :
# Create a GUI window
gui = Tk()
# Set the background colour of GUI window
gui.configure(background = "light green")
# set the name of tkinter GUI window
gui.title("GST Rate Finder")
# Set the configuration of GUI window
gui.geometry("300x300")
# Create a Original Price: label
org_price = Label(gui, text = "Original Price",
bg = "blue")
# Create a Net Price : label
net_price = Label(gui, text = "Net Price",
bg = "blue")
# Create a Find Button and attached to
# findGst function
find = Button(gui, text = "Find", fg = "Black",
bg = "Red",
command = findGst)
# Create a Gst Rate : label
gst_rate = Label(gui, text = "Gst Rate", bg = "blue")
# Create a Clear Button and attached to
# clearAll function
clear = Button(gui, text = "Clear", fg = "Black",
bg = "Red",
command = clearAll)
# grid method is used for placing
# the widgets at respective positions
# in table like structure .
# padx attributed provide x-axis margin
# from the root window to the widget.
# pady attributed provide y-axis
# margin from the widget.
org_price.grid(row = 1, column = 1,padx = 10,pady = 10)
net_price.grid(row = 2, column = 1, padx = 10, pady = 10)
find.grid(row = 3, column = 2,padx = 10,pady = 10)
gst_rate.grid(row = 4, column = 1,padx = 10, pady = 10)
clear.grid(row = 5, column = 2, padx = 10, pady = 10)
# Create a text entry box for filling or typing the information.
org_priceField = Entry(gui)
net_priceField = Entry(gui)
gst_rateField = Entry(gui)
# grid method is used for placing
# the widgets at respective positions
# in table like structure .
org_priceField.grid(row = 1, column = 2 ,padx = 10,pady = 10)
net_priceField.grid(row = 2, column = 2, padx = 10,pady = 10)
gst_rateField.grid(row = 4, column = 2, padx = 10,pady = 10)
# Start the GUI
gui.mainloop()
