Tkinter stylesheet - Tkss

This library helps you to set style to tkinter default widget using stylesheet without much work.

Quick Example:

from tkinter import *
from tkstylesheet import TkThemeLoader

_style = """
        Tk{
            background: "#565657"; /*background color of the root widget*/
        }
        
        Label{
            foreground: "#ebebeb";
            background: "#565657";
        }
        
        Button{
            foreground: "#ebebeb";
            background: "#565657";
        }
        
        """

root = Tk()

Label(root, text="label").pack()
Button(root, text="Button").pack()

theme = TkThemeLoader(root)
theme.setStylesheet(_style)  # pass as string

root.mainloop()

If you want to load tkss from a file:

1. save you theme in a file
2. load it using TkThemeLoader().loadStyleSheet(file_path)

example:

theme.tkss

Tk{
    background: "#565657";
}

Label{
    foreground: "#ebebeb";
    background: "#565657";
}

Button{
    foreground: "#ebebeb";
    background: "#565657";
}

project.py

from tkinter import *
from tkstylesheet import TkThemeLoader

root = Tk()

Label(root, text="label").pack()
Button(root, text="Button").pack()

theme = TkThemeLoader(root)
theme.loadStyleSheet("theme.tkss")  # pass file path

root.mainloop()
