销毁()而不是重复销毁

Question

我的代码创建了一个带有3个输入框和3个按钮的Tk窗口。单击按钮时，相邻的输入框和按钮本身就会消失。我想用毁灭因为我不再使用它了。问题是，它第一次工作在任何按钮/入口组件上，但当我在一个按钮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)
        if self.numPlayers==3:
            if (self.betCount!=self.numPlayers) and (not self.bettedW):
                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)
    def betE(self):
        print("betE")
        self.bettedE=True
        self.EHandSubmit.destroy()
        self.EHandEntry.destroy()
        self.suitWindow()
        self.betCount+=1
    def betST(self):
        print("betST")
        self.bettedS=True
        self.SHandSubmit.destroy()
        self.SHandEntry.destroy()
        self.suitWindow()
        self.betCount+=1
    def betW(self):
        print("betW")
        self.bettedW=True
        self.WHandSubmit.destroy()
        self.WHandEntry.destroy()
        self.suitWindow()
        self.betCount+=1
gui=BlackjackTable(3)
mainloop()

您之所以面临这个问题，是因为在这些方法中：betE()、betST()和betW()，您称之为无用的suitWindow()，它根据复杂的if条件重新绘制组件。

解决方案是首先使用suitWindow()绘制小部件，根据self.numPlayers、self.bettedE、self.bettedS、self.bettedW和self.betCount标志的值和状态消除所有if条件：

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)

一旦绘制了这些小部件，就像使用destroy()一样使用它，然后忘记suitWindow()方法。因此，剩下的三种方法成为：

    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()

全程序

随着代码的减少，程序变得不那么复杂了：
