tkdial 0.0.1

A rotatory dial tkinter widget.

TkDial

This is a circular rotatory dial-knob widget for tkinter. It can be used in place of normal slider.

Usage

Simple Example:

import tkinter as tk
from tkdial import Dial

app = tk.Tk()

dial = Dial(app, color_gradient=("white", "black"))
dial.grid(padx=10, pady=10)

app.mainloop()

Example 2

import tkinter as tk
from tkdial import Dial

app = tk.Tk()

#Some color combinations
color_combinations = [("yellow", "red"), ("white", "cyan"), ("red", "pink"), ("black", "green"),
                    ("white", "black"), ("blue", "blue"), ("green", "green"), ("white", "pink"),
                    ("red", "black"), ("green", "cyan"), ("cyan","black"), ("pink", "blue")]

for i in range (12):
    dial = Dial(master=app, color_gradient=color_combinations[i],
                unit_length=10, radius=40, needle_color=color_combinations[i][1])
    if i<6:
        dial.grid(row=1, padx=10, pady=10, column=i)
    else:
        dial.grid(row=2, padx=10, pady=10, column=11-i)

app.mainloop()

Example 3

Implemented with CustomTkinter

import customtkinter
from tkdial import Dial

customtkinter.set_appearance_mode("Dark") 
              
app = customtkinter.CTk()
app.geometry("350x400")
                
app.grid_columnconfigure((0,1), weight=1)
app.grid_rowconfigure((0,1), weight=1)

frame_1 = customtkinter.CTkFrame(master=app)
frame_1.grid(padx=20, pady=20, sticky="nswe")

dial1 = Dial(master=frame_1, color_gradient=("green", "cyan"), bg="#2a2d2e",
             text_color="white", text="Current: ", unit_length=10, radius=50)
dial1.grid(padx=20, pady=20)

dial2 = Dial(master=frame_1, color_gradient=("yellow", "white"), bg="#2a2d2e",
             text_color="white", text="Position: ", unit_length=10, radius=50)
dial2.grid(padx=20, pady=20)

dial3 = Dial(master=frame_1, color_gradient=("white", "pink"), bg="#2a2d2e",
             text_color="white", text=" ", unit_length=10, radius=50)
dial3.grid(row=0, column=1, padx=20, pady=20)

dial4 = Dial(master=frame_1, color_gradient=("red", "red"), bg="#2a2d2e",
             text_color="white", text="", unit_width=15, radius=50)
dial4.grid(row=1, column=1, padx=20, pady=20)

app.mainloop()

I hope it will be helpful for UI development in tkinter.
