Question

我创建了一个继承自标准Button的自定义Tkinter Button小部件，纯粹出于审美目的，因此我可以在整个程序中重复相同的样式，而无需每次都手动配置它。我的自定义按钮的代码在这里：

import tkinter as tk

class gameButton(tk.Button):
    def __init__(self,*args,**kwargs):
        super(gameButton,self).__init__()

        self.root=args[0]

        self.configure(text=kwargs["text"])

        self.configure(fg=kwargs["fg"],
                       activeforeground=kwargs["fg"])

        try:
            self.configure(command=kwargs["command"])
        except KeyError:
            pass

        self.configure(relief="flat",cursor="hand2")
        self.bind("<Enter>",self.hover)
        self.bind("<Leave>",self.leave)

        self.old=kwargs["bg"]
        self.dark=self.darken(self.old)

        self.configure(bg=self.old,activebackground=self.dark,
                       bd=1,relief="solid")

    def getRGB(self,h):
        it=tuple(int(h[i:i+2], 16) for i in (0, 2 ,4))
        return it

    def getHex(self,h):
        it='#%02x%02x%02x' % h
        return it

    def darken(self,h):
        currentHex=self.old.replace("#","")
        currentRGB=self.getRGB(currentHex)

        currentR=currentRGB[0]
        currentG=currentRGB[1]
        currentB=currentRGB[2]
        if currentR>30:
            newR=round(currentR-30)
        else:
            newR=0
        if currentG>30:
            newG=round(currentG-30)
        else:
            newG=0
        if currentB>30:
            newB=round(currentB-30)
        else:
            newB=0

        newRGB=(newR,newG,newB)

        newHex=self.getHex(newRGB)
        return newHex

    def hover(self,event):
        self.configure(bg=self.dark)

    def leave(self,event):
        self.configure(bg=self.old)

我试图在框架中将它们网格化的代码部分在这里（我将gameButton导入为GB）：

game=Frame(notebook,bg=bg)
notebook.add(game,text="Game")

mapb=GB(game,text="Map",compound="left",bg=bg,fg=fg)
travelb=GB(game,text="Travel",compound="left",bg=bg,fg=fg)
bagb=GB(game,text="Bag",compound="left",bg=bg,fg=fg)

pokedexb=GB(game,text="Pokédex",compound="left",bg=bg,fg=fg)
partyb=GB(game,text="Party",compound="left",bg=bg,fg=fg)
saveb=GB(game,text="Save",compound="left",bg=bg,fg=fg)

mapb.grid(row=0,column=0,padx=5,pady=5,sticky="nesw")
travelb.grid(row=0,column=1,padx=5,pady=5,sticky="nesw")
bagb.grid(row=0,column=2,padx=5,pady=5,sticky="nesw")

pokedexb.grid(row=1,column=0,padx=5,pady=5,sticky="nesw")
partyb.grid(row=1,column=1,padx=5,pady=5,sticky="nesw")
saveb.grid(row=1,column=2,padx=5,pady=5,sticky="nesw")

结果如下：

按钮在正常的根窗口中很好地网格，但它拒绝在根内的Frame内正常运行。

自定义Tkinter按钮在Frame内部无法正常网格
