如何为 Tkinter 按钮上的文本描述添加悬停功能? [英] How to add hover feature for text description on a Tkinter button?

问题描述

我想在 Tkinter 按钮上添加悬停功能，如果用户悬停鼠标光标，则会显示描述文本.我还想为该描述添加一些延迟，以免干扰.

I want to add a hover feature on a Tkinter button where if the user hovers the mouse cursor then description text displays. I also want to add some delay for that description to appear so that it would not be intrusive.

我可以尝试使用"<Enter>>>>> 和"<Leave>>>>>> 将按钮绑定到一个函数并制作一些";标签"出现在应用程序的某个角落.但这种方法可能不是最优雅的.

I can try using the "<Enter>" and "<Leave>" binding of the button to a function and make some "Label" appear in some corner of the app. But this approach may not be the most elegant.

推荐答案

这是一个使用 Pmw(python 大型小部件)作为工具提示的小片段.

Here is a small snippet using Pmw (python mega widgets) for the tool tips.

首先从安装开始:

pip install Pmw

然后这里是一个片段来了解Pmw可以做什么:

Then here is a snippet to understand what Pmw can do:

from tkinter import *
import Pmw

root = Tk()

Pmw.initialise(root) #initializing it in the root window

l = Label(root,text='Random Text')
l.pack()

b = Button(root,text='Hover me')
b.pack()

tooltip_1 = Pmw.Balloon(root) #Calling the tooltip
tooltip_1.bind(b,'This is the hover Text
Hope you get an idea of whats going on here.') #binding it and assigning a text to it

root.mainloop()

希望这能给你一个更好的主意.请记住，Pmw 可能会在稍后将 py 转换为 exe 时造成混乱(如果您有任何意图).有一种方法可以解决.

Hope this gives you a better idea. Keep in mind that Pmw could create a mess while converting the py to an exe later(if you have any intentions to). There is a way around in tho.
