Python/Tkinter根窗口背景配置

Question

我试图创建一个黑色背景的根窗口与我的按钮背景混合。

我有以下几点：

class Application(Frame): 
    def __init__(self, parent): 
     Frame.__init__(self, parent) 
     self.parent = parent 
     self.initUI() 
... 

    def initUI(self): 
     self.outputBox = Text(bg='black', fg='green', relief=SUNKEN, yscrollcommand='TRUE') 
     self.outputBox.pack(fill='both', expand=True) 
     self.button1 = Button(self, text='button1', width=40, bg ='black', fg='green', activebackground='black', activeforeground='green') 
     self.button1.pack(side=RIGHT, padx=5, pady=5) 
     self.button2 = Button(self, text='button2', width=20, bg='black', fg='green', activebackground='black', activeforeground='green') 
     self.button2.pack(side=LEFT, padx=5, pady=5) 
... 

def main(): 
    root = Tk() 
    root.geometry('1100x350+500+300') 
    root.configure(background = 'black') 
    app = Application(root) 
    root.mainloop() 

但root.configure(background = 'black')没有改变根窗口的背景颜色...有什么建议？

这工作（检查父根是如何引用）：

编辑：我编辑的代码和数字弄清其中的颜色设置：

from Tkinter import * 

class Application(Frame): 
    def __init__(self, master=None): 
     Frame.__init__(self, master) 
     self.parent = master 
     self.initUI() 

    def initUI(self): 
     self.outputBox = Text(self.parent, bg='yellow', height= 10, fg='green', relief=SUNKEN, yscrollcommand='TRUE') 
     self.outputBox.pack(fill='both', expand=True) 
     self.button1 = Button(self.parent, text='button1', width=20, bg ='blue', fg='green', activebackground='black', activeforeground='green') 
     self.button1.pack(side=RIGHT, padx=5, pady=5) 
     self.button2 = Button(self.parent, text='button2', width=25, bg='white', fg='green', activebackground='black', activeforeground='green') 
     self.button2.pack(side=LEFT, padx=5, pady=5) 

def main(): 
    root = Tk() 
    app = Application(root) 
    app.parent.geometry('300x200+100+100') 
    app.parent.configure(background = 'red') 
    app.mainloop() 

main()

其“BG '。'配置行中'不'背景'。
