Make your Tkinter application look better than ever with just two lines of code!
The theme is easily installable as a Python package
pip install sv-ttk
Note
The theme will only be applied to themable (tkinter.ttk
) widgets, and not with the regular Tkinter widgets, they only benefit from the colorscheme.
For detailed documentation, visit the wiki page.
import tkinter
from tkinter import ttk
import sv_ttk
root = tkinter.Tk()
button = ttk.Button(root, text="Click me!")
button.pack()
# This is where the magic happens
sv_ttk.set_theme("dark")
root.mainloop()
Our intention is to keep the sv-ttk
package as simple as possible, while making it easy to integrate with other libraries.
You can use the darkdetect package to detect the system color scheme. Here's an example:
import darkdetect
sv_ttk.set_theme(darkdetect.theme())
It's only a matter of an extra import and passing the result of darkdetect.theme()
to sv_ttk.set_theme()
. It's that easy!
The Sun Valley theme doesn't change the title bar color on Windows when the theme is set to dark. You can use pywinstyles to achieve this. Here's an example:
import pywinstyles, sys
def apply_theme_to_titlebar(root):
version = sys.getwindowsversion()
if version.major == 10 and version.build >= 22000:
# Set the title bar color to the background color on Windows 11 for better appearance
pywinstyles.change_header_color(root, "#1c1c1c" if sv_ttk.get_theme() == "dark" else "#fafafa")
elif version.major == 10:
pywinstyles.apply_style(root, "dark" if sv_ttk.get_theme() == "dark" else "normal")
# A hacky way to update the title bar's color on Windows 10 (it doesn't update instantly like on Windows 11)
root.wm_attributes("-alpha", 0.99)
root.wm_attributes("-alpha", 1)
# Example usage (replace `root` with the reference to your main/Toplevel window)
apply_theme_to_titlebar(root)
Note that on Windows 10, due to its limitations, you can only set the title bar's color to black for dark mode and white for light mode. On Windows 11 the title bar can be set to any color.
Warning
The apply_theme_to_titlebar
works on Windows only, so you should check whether the platform is Windows before calling this function.
Here's how the windows look after calling set_title_bar_color()
