destroy（）不会破坏重复

Question

我的代码创建一个Tk窗口，其中包含3个输入框和3个按钮。当点击一个按钮时，相邻的输入框和按钮本身应该消失。我想用摧毁，因为我不再使用它。问题在于它在任何按钮/入口组件上都是第一次工作，但是当我在其中一个销毁后单击其他任何按钮时，其他按钮都不会销毁。

class BlackjackTable: 
    def __init__(self,numPlayers): 
     self.numPlayers=numPlayers 
     self.tableWindow=Tk() 
     self.bettedE=False 
     self.bettedS=False 
     self.bettedW=False 
     self.betCount=0 
     self.suitWindow() 
    def suitWindow(self): 
     self.tableWindow.title("Blackjack Table") 
     self.tableWindow.config(bg="dark green") 
     if int(self.betCount)!=int(self.numPlayers) and (not self.bettedE): 
      self.EHandEntry=Entry(self.tableWindow,fg="white",bg="dark green",width=10) 
      self.EHandEntry.grid(row=5,column=9) 

      self.EHandSubmit=Button(self.tableWindow,text="Bet",fg="white",padx=15,pady=5,command=self.betE,bg="dark green",activebackground="dark green",activeforeground="white") 
      self.EHandSubmit.grid(row=5,column=10) 
     if self.numPlayers>=2: 
      if (self.betCount!=self.numPlayers) and (not self.bettedS): 
       self.SHandEntry=Entry(self.tableWindow,fg="white",bg="dark green",width=10) 
       self.SHandEntry.grid(row=8,column=6) 

       self.SHandSubmit=Button(self.tableWindow,text="Bet",fg="white",padx=15,pady=5,command=self.betST,bg="dark green",activebackground="dark green",activeforeground="white") 
       self.SHandSubmit.grid(row=8,column=7)

       self.WHandEntry.grid(row=5,column=3)

您遇到这个问题，因为这些方法里面：betE()，betST()和betW()你叫白白suitWindow()其重绘基于复杂if条件componenents。

的解决方案是，你通过摆脱的基础上，self.numPlayers，self.bettedE，self.bettedS，self.bettedW和self.betCount标志的价值观和国家所有的if条件绘图使用suitWindow()您的小部件开始：

def suitWindow(self): 
     self.tableWindow.title("Blackjack Table") 
     self.tableWindow.config(bg="dark green") 

     self.EHandEntry=Entry(self.tableWindow,fg="white",bg="dark green",width=10) 
     self.EHandEntry.grid(row=5,column=9) 

     self.EHandSubmit=Button(self.tableWindow,text="Bet",fg="white",padx=15,pady=5,command=self.betE,bg="dark green",activebackground="dark green",activeforeground="white") 
     self.EHandSubmit.grid(row=5,column=10) 


     self.SHandEntry=Entry(self.tableWindow,fg="white",bg="dark green",width=10) 
     self.SHandEntry.grid(row=8,column=6) 

     self.SHandSubmit=Button(self.tableWindow,text="Bet",fg="white",padx=15,pady=5,command=self.betST,bg="dark green",activebackground="dark green",activeforeground="white") 
     self.SHandSubmit.grid(row=8,column=7) 
     self.WHandEntry=Entry(self.tableWindow,fg="white",bg="dark green",width=10) 
     self.WHandEntry.grid(row=5,column=3) 

     self.WHandSubmit=Button(self.tableWindow,text="Bet",fg="white",padx=15,pady=5,command=self.betW,bg="dark green",activebackground="dark green",activeforeground="white") 
     self.WHandSubmit.grid(row=5,column=4) 

一旦这些小部件被绘制出来，就像你一样使用destroy()，并忘记了suitWindow（）方法。因此，剩下的三个方法变成：

def betE(self): 
     print("betE") 
     self.bettedE=True 
     self.EHandSubmit.destroy() 
     self.EHandEntry.destroy() 

    def betST(self): 
     print("betST") 
     self.bettedS=True 
     self.SHandSubmit.destroy() 
     self.SHandEntry.destroy() 

    def betW(self): 
     print("betW") 
     self.bettedW=True 
     self.WHandSubmit.destroy() 
     self.WHandEntry.destroy() 

全部程序

你的程序变得那么复杂为你的代码少：
