Contact book template for tkinter

A Treeview table you can add rows to and delete rows from.

What this template shows you

• Adding a row to a Treeview with .insert("", "end", values=(...))
• Finding what the user picked with .selection(), and deleting it
• Clearing entries after a successful action so the form is ready for the next one

The Python it generates

This is the actual main.py you get when you download it: standard-library tkinter, no framework, yours to edit:

import tkinter as tk
from tkinter import ttk


class Application:
    def __init__(self, root):
        self.root = root
        root.title("Contact book")
        root.geometry("520x420")

        self.label1 = tk.Label(root, text="Name")
        self.label1.place(x=20, y=20, width=60, height=26)

        self.entry1 = tk.Entry(root)
        self.entry1.place(x=90, y=18, width=180, height=28)

        self.label2 = tk.Label(root, text="Email")
        self.label2.place(x=285, y=20, width=55, height=26)

        self.entry2 = tk.Entry(root)
        self.entry2.place(x=350, y=18, width=150, height=28)

        self.button1 = tk.Button(root, text="Add", command=self.on_button1)
        self.button1.place(x=20, y=60, width=90, height=32)

        self.button2 = tk.Button(root, text="Delete selected", command=self.on_button2)
        self.button2.place(x=120, y=60, width=150, height=32)

        self.treeview1 = ttk.Treeview(root, columns=("col1", "col2"), show="headings")
        self.treeview1.heading("col1", text="Name")
        self.treeview1.heading("col2", text="Email")
        self.treeview1.place(x=20, y=105, width=480, height=250)

        self.label3 = tk.Label(root, text="")
        self.label3.place(x=20, y=368, width=480, height=26)

    def load_treeview1(self, rows):
        """Populate the table — pass any iterable of row tuples/lists."""
        self.treeview1.delete(*self.treeview1.get_children())
        for values in rows:
            self.treeview1.insert("", "end", values=values)

    def on_button1(self):
        name = self.entry1.get().strip()
        email = self.entry2.get().strip()
        if not name:
            self.label3.configure(text="Enter a name first.")
            return
        self.treeview1.insert("", "end", values=(name, email))
        self.entry1.delete(0, "end")
        self.entry2.delete(0, "end")
        self.label3.configure(text="Added " + name)

    def on_button2(self):
        picked = self.treeview1.selection()
        if not picked:
            self.label3.configure(text="Select a row to delete.")
            return
        for row in picked:
            self.treeview1.delete(row)
        self.label3.configure(text="Deleted " + str(len(picked)) + " row(s)")


if __name__ == "__main__":
    root = tk.Tk()
    app = Application(root)
    root.mainloop()
