首先，我刚刚开始编码，这是我的学校项目。我无法改变不同类别的帧和标签的颜色。这可能看起来像一个菜鸟问题，我知道我的编程非常糟糕，但任何帮助都会受到重视。
class Menubar(tk.Menu): #Creates a class called Menubar
def __init__(self, master): #Initializes the class.
menu = tk.Menu(root) #Creates a Menu with variable menu inside root.
root.config(menu=menu) #Configures it to a menu.
subMenu = tk.Menu(menu) #Creates the sub menu inside menu.
menu.add_cascade(label = "File", menu = subMenu) #Creates a drop down called File, in the submenu.
subMenu.add_command(label='New Day...', command = self.newday) #Creates a labels with a function newday.
subMenu.add_command(label='Quit', command = quit) #Creates a labels with a function quit.
subMenu2 = tk.Menu(menu) #Creates a second submenu in the main menu.
menu.add_cascade(label = 'Theme Options', menu = subMenu2) #Creates a drop down in the second sub menu.
subMenu2.add_command(label = 'White Theme', command = self.whitetheme) #Creates the label White Theme and when clicked it will a command.
subMenu2.add_command(label = 'Dark Theme', command = self.darktheme) #Creates the label Dark Theme and when clicked it will a command.
def newday(self):
#Variable t stores the name that is given to the spread sheet file.
t = str(tm.strftime("%d-%m-%Y")) + ' - ' + str(tm.strftime("%A")) + '.xlsx'
wb = xl.Workbook() #wb creates a new spread sheet file.
ws = wb.active #ws grabs the active worksheet in the spread sheet.
labels = ( #This array stores the labels and formula that will be printed to the spread sheet.
['Bags', ''],
['Notes', ''],
['£2', ''],
['£1', ''],
['50p', ''],
['20p', ''],
['10p', ''],
['5p', ''],
['2p', ''],
['1p', ''],
['Total Till', '=SUM(B3:B12)'],
['Previous Till', ''],
['Till','=B13-B14'],
['Card', ''],
['Cash', ''],
['Day Total', '=SUM(B15:B17)'],
)
r = 3 #Variable r stores value 3
c = 1 #Variable c stores value 1
for text, formulae in labels: #The for loop will be used to print the array data in to the spread sheet.
ws.cell(row=r, column=c, value=text) #This will print the labels in to the rows.
ws.cell(row=r, column=c+1, value = formulae) #This will print the formula in to the column.
r += 1
wb.save(t) #Saves the workbook usung the name in variable t
msgbox.showinfo('Daily Accounts', 'New Day created.') #Outputs a messagebox that tells the user a new day is created.
def whitetheme(self):
varframe = frame.mainlabels(self)
self.lblBags.configure(bg = "black")

我希望能够点击暗和亮主题选项，它会改变下面课程中框架和标签的颜色。
class frame(tk.Frame): #Creates the class frame where the widgets will be held.

对于长代码很抱歉，我很确定它可以做得更简单，但我刚开始。任何帮助将不胜感激。感谢

我写了一个例子来向你展示如何使用ttk样式。你创建了自己的类，继承了tkinter小部件但是你没有在__init__方法中使用它，所以我的菜单栏类给你一个例子。
import tkinter as tk
import tkinter.ttk as ttk
class Menubar(tk.Menu):
def __init__(self, master):
# create the menu using tk.Menu init method
tk.Menu.__init__(self, master)
# display menu on the master window
master.configure(menu=self)
# create style used to change theme
self.style = ttk.Style(master)
self.whitetheme()
subMenu = tk.Menu(self, tearoff=False)
self.add_cascade(label='Theme Options', menu=subMenu)
subMenu.add_command(label ='White Theme', command = self.whitetheme)
subMenu.add_command(label ='Dark Theme', command = self.darktheme)
def whitetheme(self):
self.style.configure('TFrame', background='white')
self.style.configure('TLabel', background='white', foreground="black")
def darktheme(self):
self.style.configure('TFrame', background='black')
self.style.configure('TLabel', background='black', foreground="white")
if __name__ == "__main__":
root = tk.Tk()
Menubar(root)
# use ttk frames and labels
frame = ttk.Frame(root)
frame.pack(fill='both', expand=True)
ttk.Label(frame, text="Your text here").pack(padx=20, pady=20)
root.mainloop()
