TkClassWizard

TkClassWizard - define objects graphically based on class annotations. The library allows users to create abstract "ObjectInfo" objects based on the class's parameters, which can later be converted to real Python objects and vice versa.

Main features

• Interactive definition of Python objects based on annotations.
• Tkinter based
• JSON templates
• Polymorphism
• Generic classes
• Type aliases
• Data validation
• Conversion of defined data to Python objects and vice-versa.

Installation

TkClassWizard can be installed though command prompt/terminal using the bottom commands.

Pre-requirement: Python (minimum v3.9)

pip install tkclasswiz

Example

import tkinter as tk
import tkinter.ttk as ttk
import tkclasswiz as wiz


# Normal Python classes with annotations (type hints)
class Wheel:
    def __init__(self, diameter: float):
        self.diameter = diameter

class Car:
    def __init__(self, name: str, speed: float, wheels: list[Wheel]):
        self.name = name
        self.speed = speed
        self.wheels = wheels

# Tkinter main window
root = tk.Tk("Test")

# Modified tkinter Combobox that will store actual objects instead of strings
combo = wiz.ComboBoxObjects(root)
combo.pack(fill=tk.X, padx=5)

def make_car(old = None):
    """
    Function for opening a window either in new definition mode (old = None) or
    edit mode (old != None)
    """
    assert old is None or isinstance(old, wiz.ObjectInfo)

    window = wiz.ObjectEditWindow()  # The object definition window / wizard
    window.open_object_edit_frame(Car, combo, old_data=old)  # Open the actual frame

def print_defined():
    data = combo.get()
    data = wiz.convert_to_objects(data)  # Convert any abstract ObjectInfo objects into actual Python objects
    print(f"Object: {data}; Type: {type(data)}",)  # Print the object and it's datatype


# Main GUI structure
ttk.Button(text="Define Car", command=make_car).pack()
ttk.Button(text="Edit Car", command=lambda: make_car(combo.get())).pack()
ttk.Button(text="Print defined", command=print_defined).pack()
root.mainloop()
