如何使评论显示在树视图表中的行上方？

如何解决如何使评论显示在树视图表中的行上方？

我正在尝试在此处Display message when hovering over something with mouse cursor in Python

中描述一种方法

from tkinter import *

class ToolTip(object):
    def __init__(self,widget):
        self.widget = widget
        self.tipwindow = None
        self.id = None
        self.x = self.y = 0

    def showtip(self,text):
        "display text in tooltip window"
        self.text = text
        if self.tipwindow or not self.text:
            return
        x,y,cx,cy = self.widget.bBox("insert")
        x = x + self.widget.winfo_rootx() + 57
        y = y + cy + self.widget.winfo_rooty() +27
        self.tipwindow = tw = Toplevel(self.widget)
        tw.wm_overrideredirect(1)
        tw.wm_geometry("+%d+%d" % (x,y))
        label = Label(tw,text=self.text,justify=LEFT,background="#ffffe0",relief=SOLID,borderwidth=1,font=("tahoma","8","normal"))
        label.pack(ipadx=1)

    def hidetip(self):
        tw = self.tipwindow
        self.tipwindow = None
        if tw:
            tw.destroy()

def CreatetoolTip(widget,text):
    toolTip = ToolTip(widget)
    def enter(event):
        toolTip.showtip(text)
    def leave(event):
        toolTip.hidetip()
    widget.bind('<Enter>',enter)
    widget.bind('<Leave>',leave)



button = Button(root,text = 'click mem')
button.pack()
CreatetoolTip(button,text = 'Hello World')

但是该方法不适用于Treeview表。当我尝试执行以下代码时：

tree = ttk.Treeview(frame)
tree.pack()
CreatetoolTip(tree,text = 'Hello World')

出现错误：

Traceback (most recent call last):
File "/usr/lib/python3.8/tkinter/__init__.py",line 1883,in __call__
return self.func(*args)
File "/home/polina/PycharmProjects/dynamic_table/moxa.py",line 66,in enter
toolTip.showtip(text)
File "/home/polina/PycharmProjects/dynamic_table/moxa.py",line 46,in showtip
x,cy = self.widget.bBox("insert")
File "/usr/lib/python3.8/tkinter/ttk.py",line 1217,in bBox
return self._getints(self.tk.call(self._w,"bBox",item,column)) or ''
_tkinter.TclError: Item insert not found

当我们将鼠标悬停在行上时，是否还有另一种显示评论的方法？还是上述描述可以解决？
