python - 删除网格 python Tkinter 小部件之间的自动间隙

Question

我在 Windows 上使用 python2。当我运行以下代码时，我在两个 Canvas 之间出现了间隙(见下图)，尽管当我对它们进行网格化时没有指定填充。有没有可能删除这个？

import Tkinter as tk
import ttk

class App(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        self.c1 = tk.Canvas(master=self, background='white', borderwidth=0,
                            relief=tk.FLAT)
        self.c2 = tk.Canvas(master=self, background='white', borderwidth=0,
                            relief=tk.FLAT)
        self.c1.grid(row=0, column=0, sticky=tk.NSEW)
        self.c2.grid(row=1, column=0, sticky=tk.NSEW)

        self.mainloop()

App()

感谢您的帮助!

您还需要将highlightthickness设置为零。

self.c1 = tk.Canvas(..., highlightthickness=0)

来自canvas page of effbot highlightthickness 解释为:

The width of the highlight border. The default is system specific (usually one or two pixels). (highlightThickness/HighlightThickness)
