Question

当我创建一个框架并为其设置背景颜色时，颜色会很好地显示出来。但是，当我向框架添加一个小部件时，背景颜色会消失。我尝试将相同的颜色设置为小部件的背景，但框架中仍然有许多白点。

以下是无效的代码块：

    DAC_frame = Frame(self, width=180, height=240, bg="red")
    DAC_frame.pack(side=RIGHT)

    DAC_delete_label = Label(DAC_frame, text="Delete A Term:", bg="red")
    DAC_delete_label.pack(fill=X)

    DAC_delete_entry = Entry(DAC_frame)
    DAC_delete_entry.pack()

    DAC_delete = Button(DAC_frame, text="Delete Term")
    DAC_delete.pack()

    DAC_clear = Button(DAC_frame, text="Clear Dictionary")
    DAC_clear.pack()

您无法在Tkinter中设置透明色，这就是Frame背景消失的原因。所以＆＃34;白点＆＃34;只是你的小部件的背景。您现在有两个选择：

使用Canvas here is a example

为每个小部件设置相同的backgroundcolor，对于可以将borderwidth设置为0的按钮。

from Tkconstants import RIGHT, X
from Tkinter import Frame, Tk, Label, Entry, Button
import Tkinter


class App(Tk):

    def __init__(self):
        Tkinter.Tk.__init__(self)
        DAC_frame = Frame(self, width=180, height=240, bg="red")
        DAC_frame.pack(side=RIGHT)

        DAC_delete_label = Label(DAC_frame, text="Delete A Term:", bg="red")
        DAC_delete_label.pack(fill=X)

        DAC_delete_entry = Entry(DAC_frame)
        DAC_delete_entry.pack()

        DAC_delete = Button(DAC_frame, text="Delete Term",borderwidth=0, bg="red", activebackground="red")
        DAC_delete.pack()

        DAC_clear = Button(DAC_frame, text="Clear Dictionary",borderwidth=0, bg="red", activebackground="red")
        DAC_clear.pack()

ap = App()
ap.mainloop()

窗口小部件覆盖其框架的背景
