This isnt mine, i just thought it was nice to display the available themes
import random import tkinter from tkinter import ttk from tkinter import messagebox class App(object): def __init__(self): self.root = tkinter.Tk() self.style = ttk.Style() available_themes = self.style.theme_names() random_theme = random.choice(available_themes) self.style.theme_use(random_theme) self.root.title(random_theme) frm = ttk.Frame(self.root) frm.pack(expand=True, fill='both') # create a Combobox with themes to choose from self.combo = ttk.Combobox(frm, values=available_themes) self.combo.pack(padx=32, pady=8) # make the Enter key change the style self.combo.bind('<Return>', self.change_style) # make a Button to change the style button = ttk.Button(frm, text='OK') button['command'] = self.change_style button.pack(pady=8) def change_style(self, event=None): """set the Style to the content of the Combobox""" content = self.combo.get() try: self.style.theme_use(content) except tkinter.TclError as err: messagebox.showerror('Error', err) else: self.root.title(content) app = App()
