如何更改与Tkinter的按钮颜色 [英] How to change button color with tkinter

问题描述

我不断收到以下错误：
AttributeError异常：'NoneType'对象有没有属性'配置'

 ＃创建颜色按钮
self.button =按钮（个体经营，
                     文字=点击我，
                     命令= self.color_change，
                     BG =蓝
                    ）.grid（行= 2，列= 2，粘= W）高清color_change（个体经营）：
    更改按钮的颜色    self.button.configure（BG =红）
 

解决方案

当你做 self.button =按钮（...）。格（...）什么被分配到 self.button 是格的结果（）命令的不到按钮参考对象创建的。

您需要打包/ griding之前，您 self.button 变量分配。
它应该是这个样子：

  self.button =按钮（个体经营，文本=点击我，命令= self.color_change，BG =蓝）
self.button.grid（行= 2，列= 2，粘= W）
 

I keep getting the following error: AttributeError: 'NoneType' object has no attribute 'configure'

# create color button
self.button = Button(self,
                     text = "Click Me",
                     command = self.color_change,
                     bg = "blue"
                    ).grid(row = 2, column = 2, sticky = W)

def color_change(self):
    """Changes the button's color"""

    self.button.configure(bg = "red")

解决方案

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)
