关于tkinter的notebook问题

一个窗口上有四个页面，希望可以右键点击其中任意一个可以将其那一页关闭
，试了很多次，def add_note 的第三行必须是 bind note，而不能是tab，但是改成note就变为，点击notebook任意一个地方都会删除其中一个，而不是想删哪个是哪个

原意:是想做一个类似漫画下载器一样的东西，在输入框内输入搜索的东西后，会弹出一个notebook的新的一页，之后想关闭的时候就可以将其关闭，类似选项卡一样
顺便问一下，tkinter有没有想浏览器里的选项卡一样有 ‘x’ 号

代码如下：

class a:
def destroy(self, event):
self.note.forget(self.tab)

def add_note(self, text):
    self.tab = Frame(self.note)
    self.note.add(self.tab, text=text)
    self.note.bind('<Button-3>', self.destroy)

def main(self):
    root = Tk()
    root.geometry('500x400')
    self.note = Notebook(root)
    self.tab1 = Frame(self.note)
    tab2 = Frame(self.note)
    self.note.add(self.tab1, text='热门推荐')
    self.note.add(tab2, text='推荐')
    self.note.pack()
    self.add_note('123')
    self.add_note('123')
    root.mainloop()

a().main()

ttk还是tix的notebook好像有“x”符号，点击关闭一个标签页。
