Tkinter：在顶级窗口上使用 ttk 主题

Question

from tkinter import *
import tkinter.ttk as ttk
from tkinter import ttk
from ttkthemes import themed_tk as tk
import sqlite3
from PIL import Image, ImageTk

#Root window configuration
root = tk.ThemedTk()
root.get_themes()
root.set_theme('plastik')


root.geometry("500x500")
root.resizable(height=False, width=False)


def adminlogin_function():
    # adminlogin_window configuration

    # adminlogin_window = Toplevel()
    adminlogin_window =  tk.Toplevel()
    adminlogin_window.get_themes()
    adminlogin_window.set_theme('plastik')
    
    adminlogin_window.geometry("700x400")
    
    # Widgets on adminlogin_window
    admin_username_label = Label(adminlogin_window, text="Username", fg="black")
    admin_username_label.place(x=388, y=135)
    admin_username_entry = Entry(adminlogin_window, border=2)
    admin_username_entry.place(x =490 , y =135, width = 85)
    admin_pass_label = Label(adminlogin_window, text="Password", fg="black")
    admin_pass_label.place(x = 388, y= 180)
    admin_pass_entry = Entry(adminlogin_window, border=2,show="*")
    admin_pass_entry.place(x =490 , y =180, width = 85)
    admin_login_button = Button(adminlogin_window, text="Login")
    admin_login_button.place(x = 430, y= 230, width=100)
    adminlogin_window.mainloop()
adminlogin_button = ttk.Button(root, text="Admin Login", command = adminlogin_function)
adminlogin_button.place(x=250, y=160, width = 200)

如何在 Toplevel() 窗口上使用 ttkthemes？它对于根窗口工作正常，但对于顶级窗口则不起作用。我找不到这方面的任何文档

Answer 1

您无需手动执行任何操作，一旦主题应用于主窗口，所有其他窗口和小部件都会继承该主题，如果您在其前面添加

ttk

（从中导入），例如：

ttk.Label(...)
ttk.Entry(....)
ttk.Button(...)

而且，

adminlogin_window =  tk.Toplevel()

不应该有

tk

，因为你的

tk

实际上是

from ttkthemes import themed_tk as tk

，所以只需说：

adminlogin_window =  Toplevel() #this uses toplevel from tkinter

你的功能是：

def adminlogin_function():
    # adminlogin_window configuration
    adminlogin_window =  Toplevel()    
    adminlogin_window.geometry("700x400")
    
    # Widgets on adminlogin_window
    admin_username_label = ttk.Label(adminlogin_window, text="Username")
    admin_username_label.place(x=388, y=135)
    admin_username_entry = ttk.Entry(adminlogin_window)
    admin_username_entry.place(x =490 , y =135, width = 85)
    admin_pass_label = ttk.Label(adminlogin_window, text="Password")
    admin_pass_label.place(x = 388, y= 180)
    admin_pass_entry = ttk.Entry(adminlogin_window,show="*")
    admin_pass_entry.place(x =490 , y =180, width = 85)
    admin_login_button = ttk.Button(adminlogin_window, text="Login")
    admin_login_button.place(x = 430, y= 230, width=100)

请注意，我从小部件中删除了

fg

和

border

选项，因为

ttk

不支持其小部件的这些选项，更改这些选项相当麻烦。我还删除了

adminlogin_window.mainloop()

，因为

Toplevel

没有必要拥有

mainloop()

。
