Question

我正在尝试用Tkinter创建一个初学者程序来模拟NFL游戏。我在使用Tkinter创建“记分牌”时遇到困难。下面的代码在一个窗口中显示部分记分板，在另一个窗口中显示两个菜单按钮。为什么这些在单独的窗口？我正在尝试将两个菜单按钮显示在“Away Team”和“Home Team”旁边，以便用户可以选择他们想要的团队。目前还不担心计算，只是尝试启动GUI并首先运行。有什么建议？谢谢！

你的根是主人。即：

global root
root = master

OptionMenu应与其他标签贴在同一框架上，以便将它们展示在一起：

self.txtTeamA = tk.OptionMenu(self.frame, var, *teams)

“我怎样才能使它们彼此独立？”

简单来说，您应该使用两个不同的变量来存储所选的选项。在您的代码中，它们都与var相关联，因此更改一个OptionMenu更改var会更改另一个OptionMenu。

varA = tk.StringVar(root)
varA.set('Arizona Cardinals')

varB = tk.StringVar(root)
varB.set('Baltimore Ravens')

self.txtTeamA = tk.OptionMenu(root, varA, *teams)

self.txtTeamB = tk.OptionMenu(root, varB, *teams)

Python Tkinter MenuButton
