Question

我正在尝试使用Tkinter在Python中创建一个简单的GUI计算器。但是，按钮的宽度通常会偏离1或2像素。有没有办法强制所有按钮具有相同的宽度。

我知道 ipadx 方法;但是，它会在按钮的两侧添加像素。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.Btn8.grid(column=1, row=0, padx=px, pady=py)

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sticky几何管理器的grid选项将按钮“粘贴”到其包含单元格的所有四个边（即Tkinter.N + Tkinter.S + Tkinter.E + Tkinter.W）。如果要强制实施最小宽度，则可以设置按钮宽度或更好地使用grid_columnconfigure。

另外，真的考虑不要在构建你的UI时使用复制/粘贴 - 如果你有多个具有相同选项的按钮，至少将它们放在字典中，使用函数或functools.partial。 Tkinter使得编写干净的UI代码非常容易，以后你会感谢自己...

如何在tkinter中设置Button的宽度？
