High Definition App Scaling – Tkinter CustomTkinter 21

In this video we’ll talk about high definition scaling for apps in CustomTkinter and Python.

What happens to your app if your user has different monitor display settings? What if they have scaling turned on?

Scaling apps in CustomTkinter is super easy and done automatically.

I’ll show you how to turn it off, or over-ride the scaling in any way you choose.

Python Code: ctk_customcolor2.py
(Github Code)

from tkinter import *
import customtkinter

customtkinter.set_appearance_mode("dark")  # Modes: system (default), light, dark
customtkinter.set_default_color_theme("themes/red.json")  # Themes: blue (default), dark-blue, green
# Turn off scaling
customtkinter.deactivate_automatic_dpi_awareness()
# Scale Window
customtkinter.set_window_scaling(1.5)
# Scale Widgets
customtkinter.set_widget_scaling(1.5) 

#root = Tk()
root = customtkinter.CTk()

root.title('Tkinter.com - CustomTkinter Custom Color Themes')
root.iconbitmap('images/codemy.ico')
root.geometry('700x550')

mode = "dark"

def change_colors(choice):
	customtkinter.set_default_color_theme(choice)

def change():
	global mode
	if mode == "dark":
		customtkinter.set_appearance_mode("light")
		mode = "light"
		# Clear text box
		my_text.delete(0.0, END)
		my_text.insert(END, "This is Light Mode...")
	else:
		customtkinter.set_appearance_mode("dark")
		mode = "dark"
		# Clear text box
		my_text.delete(0.0, END)
		my_text.insert(END, "This is Dark Mode...")


my_text = customtkinter.CTkTextbox(root, width=600, height=300)
my_text.pack(pady=20)

my_button = customtkinter.CTkButton(root, text="Change Light/Dark", command=change)
my_button.pack(pady=20)

colors = ["blue", "dark-blue", "green"]
my_option = customtkinter.CTkOptionMenu(root, values=colors, command=change_colors)
my_option.pack(pady=10)

my_progress = customtkinter.CTkProgressBar(root, orientation="horizontal")
my_progress.pack(pady=20)





root.mainloop()
