ttk 创建和使用自定义主题

Question

我正在尝试在我的程序中加入可自定义的主题选择。我一直在参考这个指南：http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/ttk-themes.html，但我迷路了。

这是我一直用来解决这个问题的示例代码。我正确地创建了一个新主题“阴影”，但下一部分我正在努力。让我们保持简单，在“阴影”主题中说，我想将框架背景更改为黑色，将按钮背景更改为海军蓝，将按钮前景更改为白色。

我该怎么做？

from tkinter import *
from tkinter import ttk

class Main:
    def __init__(self, master):
        self.master = master
        self.main_button = ttk.Button(self.master, text = 'New', command = self.new_window)
        self.main_button.grid()

    def new_window(self):
        pop_up = Top(self.master)

class Top:
    def __init__(self, master):
        pop_up = self.pop_up = Toplevel(master)
        self.pop_up_frame = ttk.Frame(pop_up, height = 100, width = 100)
        self.pop_up_frame.grid(sticky = E+W+S+N)
        self.s = ttk.Style()
        self.s.theme_create('shadow', parent = 'default')

        print(self.s.theme_names())

        self.c1_button = ttk.Button(pop_up, text = 'Default', command = self.get_default)
        self.c2_button = ttk.Button(pop_up, text = 'Shadow', command = self.get_shadow)

        self.c1_button.grid()
        self.c2_button.grid()    

    def get_default(self):
        self.s.theme_use('default')

    def get_shadow(self):
        self.s.theme_use('shadow')


root = Tk()

app = Main(root)

root.mainloop()

一如既往，谢谢！

这太难了。

这是其他任何人试图解决这个问题的解决方案：

from tkinter import *
from tkinter import ttk

class Main:
    def __init__(self, master):
        self.master = master
        self.main_button = ttk.Button(self.master, text = 'New', command = self.new_window)
        self.main_button.grid()

    def new_window(self):
        pop_up = Top(self.master)

class Top:
    def __init__(self, master):
        pop_up = self.pop_up = Toplevel(master)
        self.pop_up_frame = ttk.Frame(pop_up, height = 100, width = 100)
        self.pop_up_frame.grid(sticky = E+W+S+N)
        self.s = ttk.Style()
        self.s.theme_create('shadow', parent = 'default')

        print(self.s.theme_names())

        self.c1_button = ttk.Button(pop_up, text = 'Default', command = self.get_default)
        self.c2_button = ttk.Button(pop_up, text = 'Vista', command = self.get_shadow)

        self.c1_button.grid()
        self.c2_button.grid()

    def get_default(self):
        self.s.theme_use('default')

    def get_shadow(self):
        self.s.theme_use('vista')
        self.s.configure('TButton', foreground = 'white', background = 'blue')
        self.s.configure('TFrame', background = 'black')



root = Tk()

app = Main(root)

root.mainloop()

为简化Gregory6106's answer，您可以使用.configure() 修改您当前的主题主题。

from tkinter import *
from tkinter import ttk

class MainPage(ttk.Frame):
    def __init__(self, master):
        ttk.Frame.__init__(self, master)
        self.main_label = ttk.Label(self, text="Pointless Text")
        self.main_button = ttk.Button(self, text="Pointless Button")
        self.main_label.pack(padx=5, pady=5)
        self.main_button.pack(padx=5, pady=5)

        # Configure custom theme
        self.s = ttk.Style()
        self.s.configure('TLabel', foreground='red', background='grey')
        self.s.configure('TButton', foreground='white', background='blue')
        self.s.configure('TFrame', background='black')


root = Tk()
app_frame = MainPage(root)
app_frame.pack()
root.mainloop()

注意：此解决方案通过配置预先存在的主题而不是创建新主题来工作。因此，如果您计划在运行时切换回原始主题，这可能不起作用。
