Passing argument to tkinter button command in python
Here are few steps to be followed for writing a code to pass the argument to tkinter button.
1)At first ,you need to import tkinter library and assign alias ‘tk’.
#import tkinter library and assign alias 'tk' import tkinter as tk
2)Define a function to handle the button clicks.
#Define a function to handle the button clicks
def Button_Clicked(arg1, arg2):
print("arg1:", arg1, "arg2:", arg2)
3)Create the main application window.
#Create the main application window window = tk.Tk()
4)Create a button widget.
#Create a button widget
button = tk.Button(window, text="Click me", command=lambda:Button_Clicked("Hello", "python"))
button.pack()
5)Start the main event loop.
#Start the main event loop window.mainloop()
After performing this steps you will get a output for your code as follows:
arg1: Hello arg2: python
#import tkinter library and assign alias 'tk'
import tkinter as tk
#Define a function to handle the button clicks
def Button_Clicked(arg1, arg2):
print("arg1:", arg1, "arg2:", arg2)
#Create the main application window
window = tk.Tk()
#Create a button widget
button = tk.Button(window, text="Click me", command=lambda:Button_Clicked("Hello", "python"))
button.pack()
#Start the main event loop
window.mainloop()
OUTPUT:
