Python 如何在tkinter中设置按钮的宽度？

我正在尝试用Tkinter用Python制作一个简单的GUI计算器。但是，按钮的宽度通常会减少1或2个像素。有没有办法强制所有按钮的宽度相同

我知道ipadx方法；但是，它会将像素添加到按钮的两侧。当按钮的宽度为奇数时，这会导致问题

那么，施加均匀宽度的最佳方法是什么

这是我的代码：

self.SC.Ca.Btn7 = Tkinter.Button(self.SC.Ca.BtnFrame, text="7", bd=self.SCbw, fg=self.SCfg,
                                 bg=self.SCbg, activeforeground=self.SCfg, activebackground=self.SCbg, font=self.SCfob)
self.SC.Ca.Btn7.grid(column=0, row=0, padx=px, pady=py)

self.SC.Ca.Btn8 = Tkinter.Button(self.SC.Ca.BtnFrame, text="8", bd=self.SCbw, fg=self.SCfg,
                                 bg=self.SCbg, activeforeground=self.SCfg, activebackground=self.SCbg, font=self.SCfob)

self.SC.Ca.Btn9 = Tkinter.Button(self.SC.Ca.BtnFrame, text="9", bd=self.SCbw, fg=self.SCfg,
                                 bg=self.SCbg, activeforeground=self.SCfg, activebackground=self.SCbg, font=self.SCfob)

使用

网格

几何体管理器的

粘滞

选项将按钮“粘滞”到其包含单元格的所有四个侧面（即

Tkinter.N+Tkinter.S+Tkinter.e+Tkinter.W

）。如果要强制执行最小宽度，则可以设置按钮宽度，或者更好地使用

grid\u columnconfigure

---

也要考虑在复制UI时不要使用复制/粘贴——如果你有多个按钮有相同的选项，至少把它们放在字典里，使用一个函数或<代码>函数工具。Tkinter使编写干净的UI代码变得非常容易，稍后您会感谢您自己……

而不是非常冗长的

Tkinter.N+Tkinter.S+Tkinter.E+Tkinter.W）

您可以使用

nsew

。使用这样的Tkinter常数真的没有意义。底层的tk常量永远不会改变。Tk已经使用相同的值几十年或更长时间了。
