theme_settings(themename, settings)
Temporarily sets the current theme to themename, apply specified settings and then restore the previous theme.
Each key in settings is a style and each value may contain the keys ‘configure’, ‘map’, ‘layout’ and ‘element create’ and they are expected to have the same format as specified by the methods Style.configure(), Style.map(), Style.layout() and Style.element_create() respectively.
As an example, let’s change the Combobox for the default theme a bit:
from tkinter import ttk
import tkinter
root = tkinter.Tk()
style = ttk.Style()
style.theme_settings("default", {
"TCombobox": {
"configure": {"padding": 5},
"map": {
"background": [("active", "green2"),
("!disabled", "green4")],
"fieldbackground": [("!disabled", "green3")],
"foreground": [("focus", "OliveDrab1"),
("!disabled", "OliveDrab2")]
}
}
})
combo = ttk.Combobox().pack()
root.mainloop()
