form for tkinter

tkinter_form

tk_form is a simple module that helps you to create forms in tkinter easily and quickly from a base dictionary, saving certain repetitive tasks in the creation of a form and adding the verification of integer and float variables. In simple words it is similar to having a tkinter variable. Its value is a dictionary.

Install

pip install tkinter_form

Tutorial

Fast Example

import tkinter as tk

from tkinter_form import Form



class App(tk.Tk):

    def __init__(self) -> None:

        super().__init__()

        estruct = {

            "high": 1.0,

            "width": 1.0,

            "round": False,

            "type of calculation": ["calculate area", "calculate perimeter"],

            "result": "",

        }

        self.form = Form(

            self,

            name_form="calculations of a rectangle",

            form_dict=estruct,

            name_config="calculate",

            button=True

        )

        self.form.pack()

        self.button = self.form.button



        self.button.config(command=self.calculate)

        self.mainloop()

    def calculate(self):

        """

        Calculate values rectangle

        """

        dict_vals = self.form.get()

        if dict_vals["type of calculation"] == "calculate area":

            value = dict_vals["high"] * dict_vals["width"]

        elif dict_vals["type of calculation"] == "calculate perimeter":

            value = 2 * dict_vals["high"] + 2 * dict_vals["width"]

        else:

            value = 0

        if dict_vals["round"]:

            value = round(value)

        result = {"result": str(value)}

        self.form.set(result)

if __name__ == "__main__":

    App()

With these lines we create the interface that performs the calculations of area and perimeter of a rectangle. This frees us the declaration of the labels and other objects returning a ttk.LabelFrame with the additional methods set(), get() and the attributes widgets and button.
