Tkinter：在顶级窗口上使用ttkthemes

编程问答 2022-06-12

问题描述

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？对于根窗口，它可以正常工作，但对于顶级窗口，则不起作用。我找不到与此有关的任何文档

解决方法

您无需手动执行任何操作，一旦将主题应用于主窗口，则其他所有窗口和小部件都可以在主题上加上ttk（从中导入）来继承主题，例如：

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

另外，adminlogin_window = tk.Toplevel()应该有tk，因为您的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

您的功能将是：

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)

这里的通知我已从窗口小部件中删除了fg和border选项，因为ttk不支持其窗口小部件的选项，更改它们非常麻烦。 Ive还删除了adminlogin_window.mainloop()，因为Toplevel不必拥有mainloop()

希望这消除了您的疑虑，请让我知道是否有任何错误。
