🐍 Python UI Programming Series — Part 7: Advanced Widgets in Tkinter – Combobox, Checkbutton, Radiobutton, and More

---

📘 Overview

By now, you've built a multi-page, database-connected Tkinter app with validation and styling. Next, let’s explore advanced widgets that let users interact with your app in more dynamic ways.

In this part, you’ll learn how to use:

• Combobox (dropdown)

• Checkbutton (toggle options)

• Radiobutton (single choice selection)

• Spinbox (numeric selection)

• Listbox (multiple options)

---

🎛️ Why Use Advanced Widgets?

Advanced widgets:

• Enhance interactivity and user experience

• Make your UI feel more like modern apps

• Reduce typing errors by using selectable input

---

✅ 1. Combobox – Dropdown Menu

from tkinter import ttk

root = tk.Tk()
root.title("Combobox Example")

ttk.Label(root, text="Choose a language:").pack(pady=5)

combo = ttk.Combobox(root, values=["Python", "JavaScript", "C++", "Java"])
combo.pack(pady=5)
combo.current(0)  # Set default value

def show_choice():
    messagebox.showinfo("Selected", f"You chose {combo.get()}")

ttk.Button(root, text="Submit", command=show_choice).pack(pady=10)

root.mainloop()

---

✅ 2. Checkbutton – Toggle Options

var_python = tk.IntVar()

check = tk.Checkbutton(root, text="I know Python", variable=var_python)
check.pack(pady=5)

def check_status():
    status = "Yes" if var_python.get() else "No"
    messagebox.showinfo("Checked?", f"Knows Python? {status}")

tk.Button(root, text="Check", command=check_status).pack(pady=5)

🧠 Use IntVar() or BooleanVar() to track check state.

---

✅ 3. Radiobutton – Single Selection

language = tk.StringVar(value="Python")

tk.Label(root, text="Favorite Language:").pack()
tk.Radiobutton(root, text="Python", variable=language, value="Python").pack()
tk.Radiobutton(root, text="Java", variable=language, value="Java").pack()
tk.Radiobutton(root, text="C++", variable=language, value="C++").pack()

def show_language():
    messagebox.showinfo("Language", f"You selected {language.get()}")

tk.Button(root, text="Submit", command=show_language).pack(pady=10)

---

✅ 4. Spinbox – Numeric Selection

spin = tk.Spinbox(root, from_=1, to=10)
spin.pack(pady=5)

def show_number():
    messagebox.showinfo("Selected", f"Number: {spin.get()}")

tk.Button(root, text="Get Number", command=show_number).pack()

🧮 Useful for quantities, age, or any numeric input.

---

✅ 5. Listbox – Multi-Select Option

listbox = tk.Listbox(root, selectmode="multiple")
langs = ["Python", "Java", "C++", "Go", "Rust"]
for lang in langs:
    listbox.insert(tk.END, lang)
listbox.pack(pady=5)

def show_selected():
    items = [listbox.get(i) for i in listbox.curselection()]
    messagebox.showinfo("Selection", f"You selected: {', '.join(items)}")

tk.Button(root, text="Show Selected", command=show_selected).pack(pady=5)

---

🧠 Tip: Use tk.Variable() Types for Dynamic Updates

• IntVar() — for integers (e.g., Checkbutton)

• StringVar() — for text (e.g., Entry, Radiobutton)

• DoubleVar() — for floats

• BooleanVar() — for true/false values

These make it easy to link widget values to your app logic.
