tkinter TreeView tag_configure

The tag_configure method in the TreeView widget of tkinter is used to configure the style and appearance of a particular tag in the treeview widget.

Syntax:

treeview.tag_configure(tag_name, **kwargs)

Parameters:
- tag_name: The name of the tag to be configured.
- kwargs: A dictionary containing the configuration options for the tag.

Example:

import tkinter as tk
from tkinter import ttk

# Create the tkinter window
root = tk.Tk()
root.title("TreeView Example")

# Create the TreeView widget
treeview = ttk.Treeview(root)

# Add some items to the TreeView
treeview.insert("", "0", "item1", text="Item 1")
treeview.insert("", "1", "item2", text="Item 2")
treeview.insert("", "2", "item3", text="Item 3")

# Add a tag to the first item
treeview.tag_configure("tag1", background="green")

# Apply the tag to the first item
treeview.item("item1", tags=("tag1",))

# Pack the TreeView widget and run the mainloop
treeview.pack()
root.mainloop()

In the above example, a tag named "tag1" is created and configured with a green background color. The tag is then applied to the first item in the TreeView widget. The resulting TreeView will have the first item highlighted with a green background.
