Python Tkinter MenuButton

Question

我想創建一個Tkinter的初學者程序，它將模擬NFL遊戲。我在與Tkinter創建我的'記分牌'時陷入困境。下面的代碼會在一個窗口中顯示部分記分板，並在另一個窗口中顯示兩個菜單按鈕。爲什麼這些在單獨的窗口？我試圖讓兩個菜單按鈕顯示在「客隊」和「主隊」旁邊，以便用戶可以選擇他們想要的隊伍。目前還不擔心calc，只是試圖讓GUI先運行起來。有什麼建議麼？謝謝！

你的根是主人。即：

global root 
root = master 

而且OptionMenu應連接到相同的幀等標籤，以顯示他們彼此的旁邊：

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

---

「我怎樣才能讓他們相互獨立？」

簡而言之，您應該使用兩個不同的變量來存儲選定的選項。在你的代碼中，它們都與var相關聯，因此在更改一個OptionMenu時會更改var，這會更改另一個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)
