Question

我在tkinter应用程序中搜索工具提示。现在，我在youtube上找到了一个示例。但是此工具提示出现在后台，没有用。我如何才能将其始终放在我的应用程序前面，以便用户意识到它？

查看我的图片：工具提示文本显示在我的“应用程序”窗口后面。如何将其移到我的应用程序的前面？

        self.tw= None
        if tw:
            tw.destroy()

我还需要mybe帖子，我如何使用它。

import tkinter as tk
from tkinter import ttk
import ToolTip

....

loadbtn = tk.Button(labelframe, text='Load', width=15, command=self.buttonLoadIni)
loadbtn.grid(row=1,column=0, padx=10, pady=5)
ToolTip.CreateToolTip(loadbtn, 'Load the Settings.ini file')

供您参考：

import tkinter as tk
from tkinter import ttk
import ToolTip

def load():
    pass

root = tk.Tk()
loadbtn = tk.Button(root, text='Load', width=15, command=load)
loadbtn.grid(row=1,column=0, padx=10, pady=5)
ToolTip.CreateToolTip(loadbtn, 'Load the Settings.ini file')

root.mainloop()

工具提示的位置错误：enter image description here

良好的定位（内置）-也许可以使用???： enter image description here

为什么工具提示出现在后台
