tkvariable 0.1.0

Efficient Tkinter variable management with dynamic creation and tracing.

TkVar: Tkinter Variable Manager

TkVar is a Python utility that simplifies managing variables in Tkinter applications. With a singleton implementation, it ensures efficient handling of variables, supports dynamic creation and updates, and integrates seamlessly with Tkinter's tracing mechanisms for variable change events.

Features

• Singleton Design: Guarantees a single instance of the variable manager.
• Dynamic Variable Management: Automatically assigns appropriate Tkinter variable types (StringVar, IntVar, DoubleVar, BooleanVar) based on value types.
• Trace Support: Easily attach and remove callbacks to monitor or respond to variable changes.
• Centralized Access: Manage all variables through a single interface.

Installation

You can integrate TkVar into your Tkinter projects by including the tkvariable.py file.

Usage

Initialization

Start by initializing the TkVar instance with a tk.Tk master:

import tkinter as tk
from tkvariable import variable

root = tk.Tk()
variable.init(root)

Creating and Accessing Variables

variable["username"] = "Guest"  # Create a StringVar
print(variable["username"].get())  # Access the variable

Tracing Variable Changes

def on_change(*args):
    print("Variable changed!")

variable.map("username", on_change, "write")

Updating Variable Values

variable.set("username", "Admin")

Retrieving All Variables

print(variable.variables)
