python - Python/Tkinter 根窗口后台配置

Question

我正在尝试创建一个带有黑色背景的根窗口以与我的按钮背景混合。

我有以下内容：

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()  

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

Answer 1

这有效（检查如何引用父根）：

编辑：我编辑了代码和图形以明确设置颜色的位置：

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()

它在 .configure 行中的“bg”不是“背景”。
