The Label widget is used to display text or images.
Example:
import tkinter as tk
# Create the main window
root = tk.Tk()
root.title("Label Example")
root.geometry("300x200")
# Create a Label widget
label = tk.Label(root, text="Hello, Tkinter!")
label.pack(pady=20) # Add some padding for better layout
# Run the application
root.mainloop()
The Button widget is used to perform an action when clicked.
Example:
import tkinter as tk
def on_button_click():
label.config(text="Button Clicked!")
# Create the main window
root = tk.Tk()
root.title("Button Example")
root.geometry("300x200")
# Create a Label widget
label = tk.Label(root, text="Press the Button")
label.pack(pady=10)
# Create a Button widget
button = tk.Button(root, text="Click Me", command=on_button_click)
button.pack(pady=10)
# Run the application
root.mainloop()
The Entry widget is used to accept single-line text input from the user.
Example:
import tkinter as tk
def on_button_click():
label.config(text="Hello, " + entry.get())
# Create the main window
root = tk.Tk()
root.title("Entry Example")
root.geometry("300x200")
# Create a Label widget
label = tk.Label(root, text="Enter your name:")
label.pack(pady=10)
# Create an Entry widget
entry = tk.Entry(root)
entry.pack(pady=10)
# Create a Button widget
button = tk.Button(root, text="Submit", command=on_button_click)
button.pack(pady=10)
# Run the application
root.mainloop()
The Text widget is used for multi-line text input.
Example:
import tkinter as tk
# Create the main window
root = tk.Tk()
root.title("Text Example")
root.geometry("300x200")
# Create a Text widget
text = tk.Text(root, height=5, width=30)
text.pack(pady=10)
# Run the application
root.mainloop()
The Checkbutton widget is used to select or deselect an option.
Example:
import tkinter as tk
def on_checkbutton_toggle():
label.config(text="Checked" if var.get() else "Unchecked")
# Create the main window
root = tk.Tk()
root.title("Checkbutton Example")
root.geometry("300x200")
# Create an IntVar for the Checkbutton
var = tk.IntVar()
# Create a Checkbutton widget
checkbutton = tk.Checkbutton(root, text="Check Me", variable=var, command=on_checkbutton_toggle)
checkbutton.pack(pady=10)
# Create a Label widget
label = tk.Label(root, text="Unchecked")
label.pack(pady=10)
# Run the application
root.mainloop()
The Radiobutton widget is used to select one option from a set of options.
Example:
import tkinter as tk
def on_radiobutton_select():
label.config(text="Selected: " + str(var.get()))
# Create the main window
root = tk.Tk()
root.title("Radiobutton Example")
root.geometry("300x200")
# Create an IntVar for the Radiobuttons
var = tk.IntVar()
# Create Radiobutton widgets
radiobutton1 = tk.Radiobutton(root, text="Option 1", variable=var, value=1, command=on_radiobutton_select)
radiobutton1.pack(pady=5)
radiobutton2 = tk.Radiobutton(root, text="Option 2", variable=var, value=2, command=on_radiobutton_select)
radiobutton2.pack(pady=5)
# Create a Label widget
label = tk.Label(root, text="Selected: None")
label.pack(pady=10)
# Run the application
root.mainloop()
The Listbox widget is used to display a list of options.
Example:
import tkinter as tk
def on_listbox_select(event):
selection = event.widget.curselection()
if selection:
index = selection[0]
data = event.widget.get(index)
label.config(text="Selected: " + data)
# Create the main window
root = tk.Tk()
root.title("Listbox Example")
root.geometry("300x200")
# Create a Listbox widget
listbox = tk.Listbox(root)
listbox.pack(pady=10)
listbox.insert(1, "Option 1")
listbox.insert(2, "Option 2")
listbox.insert(3, "Option 3")
# Bind the select event
listbox.bind("<>", on_listbox_select)
# Create a Label widget
label = tk.Label(root, text="Selected: None")
label.pack(pady=10)
# Run the application
root.mainloop()
The Canvas widget is used for drawing shapes, text, and images.
Example:
import tkinter as tk
# Create the main window
root = tk.Tk()
root.title("Canvas Example")
root.geometry("300x200")
# Create a Canvas widget
canvas = tk.Canvas(root, width=200, height=100)
canvas.pack(pady=10)
# Draw shapes on the Canvas
canvas.create_line(0, 0, 200, 100, fill="blue")
canvas.create_rectangle(50, 25, 150, 75, fill="red")
# Run the application
root.mainloop()
The Frame widget is used as a container to hold other widgets.
Example:
import tkinter as tk
# Create the main window
root = tk.Tk()
root.title("Frame Example")
root.geometry("300x200")
# Create a Frame widget
frame = tk.Frame(root, borderwidth=2, relief="sunken")
frame.pack(pady=10, padx=10, fill="both", expand=True)
# Create widgets inside the Frame
label = tk.Label(frame, text="This is inside a frame")
label.pack(pady=10)
button = tk.Button(frame, text="Click Me")
button.pack(pady=10)
# Run the application
root.mainloop()
This step-by-step guide covers the basic widgets in Tkinter. Each example demonstrates how to create and use a specific widget, and you can expand these examples to build more complex GUI applications.
