photo = PhotoImage(file="add.png")
b = Button(master, image=photo, command=callback, height=50, width=150)
b.pack()

def callback():
    print "Clicked!"

photo = PhotoImage(file="add.png")
b = Button(master, image=photo, text="Click Me", command=callback, height=50, width=150, compound=LEFT)
b.pack()

mainloop()

Leveraging the Power of the Tkinter Toolkit: Crafting a Main Menu Bar
For many Python GUI applications, the main menu is not just a feature; it’s the nucleus. Being the focal point, it is the bridge that connects users to various app functionalities.
Here’s an illustrative example of what a menu crafted with Tkinter looks like:

Constructing the Tkinter Menubar

Designing an intuitive menu using Tkinter is not a herculean task. Here’s a concise and detailed breakdown of the process. Take note that every menu item, like “New”, “Open”, or “Save”, usually maps to a unique callback function.

from Tkinter import *

def donothing():
   x = 0
 
root = Tk()
menubar = Menu(root)
filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="New", command=donothing)
filemenu.add_command(label="Open", command=donothing)
filemenu.add_command(label="Save", command=donothing)
filemenu.add_separator()
filemenu.add_command(label="Exit", command=root.quit)
menubar.add_cascade(label="File", menu=filemenu)

helpmenu = Menu(menubar, tearoff=0)
helpmenu.add_command(label="Help Index", command=donothing)
helpmenu.add_command(label="About...", command=donothing)
menubar.add_cascade(label="Help", menu=helpmenu)

root.config(menu=menubar)
root.mainloop()

The journey of crafting a main menubar kicks off with this fundamental call:

1

menubar = Menu(root)

Menus in graphical interfaces often house a collection of submenus. These can range from File to Edit to View or even Tools. To create these submenus, the pattern remains consistent, utilizing the Menu() call:

1

filemenu = Menu(menubar, tearoff=0)

The final step in the process involves populating these submenus with individual menu items using the add_command() method:

1

filemenu.add_command(label="New", command=donothing)

In our demo here, the donothing() function is a placeholder callback for each menu item. However, in real-world scenarios, every menu item would point to its specific callback function.
