小部件覆盖其框架的背景

Question

当我创建一个框架并为其设置背景颜色时，颜色显示得很好。但是，当我将小部件添加到框架时，背景颜色消失了。我已经尝试将相同的颜色设置为小部件的背景，但框架中仍然有很多白点。

这是不起作用的代码块：

    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 中设置透明颜色，这就是您 Frame 的背景消失的原因。所以 "white spots" 只是您的小部件的背景。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背景颜色，对于按钮，您可以将 borderwidth 设置为 0。

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()
