我以前问过这个问题,但没有成功的答案,所以我会再试一次
下面是按下按钮时改变按钮背景颜色的代码。它基本上取“eleNum”这个数字,然后用它打印出4个0到40的按钮面板
这是奇怪的一点。4号面板工作正常,但其他面板只是给我一个错误。例如,如果我按下面板2中的一个按钮:
line 113, in chooser
self.Buttons2[index].onfigure(bg="orange")
AttributreError: 'int' object has no attribute 'configure'
这是我的密码
def floorChooserButtons( self, eleNum, floors, yStart, yEnd, xStart, xEnd):
self.Buttons1 = [i for i in range(41)]
self.Buttons2 = [i for i in range(41)]
self.Buttons3 = [i for i in range(41)]
self.Buttons4 = [i for i in range(41)]

self.eleNumber[0].grid(row = xStart-1, column =yStart+1, columnspan=3)

if(yPos == yEnd):

if eleNum is 4:
self.Buttons4[index].configure(bg="red")
列表中有整数。你自己把它们放在那里,例如:
self.Buttons2 = [i for i in range(41)]
。在此之后,您只将其中的一些更改为按钮,例如:self.Buttons2[floor] = tk.Button( ...
然后尝试对整数调用
configure
方法—错误消息非常直接地解释了这一点。显然整数没有configure
方法因此,您的代码将始终只适用于一个面板。在使用给定的
eleNum
调用floorChooserButtons
之后,所有列表都被重置为整数,只有与eleNum
对应的列表被按钮填充(仍然,仅适用于floors
列表中的索引)快速解决方法是移动零件:
给建造师。然后,在为所有面板调用
floorChooserButtons
之后,您将用实际的按钮而不是数字填充它们。你的整个构造对我来说仍然没有意义(为什么你会在列表中有整数,并打算在其中存储按钮?)作为补充说明,您错误地使用了
is
运算符。它在这里意外地起作用,因为Python中的整数是不可变的,但可读性不强。对于值相等测试,应该使用==
