Python 在Tkinter中输入键绑定

python user-interface tkinter button

Python 在Tkinter中输入键绑定,python,user-interface,tkinter,button,Python,User Interface,Tkinter,Button,所以，我一直在尝试绑定enter键来按下这个python程序中的按钮——是的，我已经看到了许多其他与此相关的问题，但是他们的代码都没有因为任何原因与这个程序一起工作。张贴下面的代码，看看是否有人有一个好的解决方案下面的代码按预期完成了所有操作——它将调出GUI，显示goofy jar图片、按钮和带有预填充文本的输入字段，但键盘上的enter键不会产生结果，因为我用鼠标按下按钮时会发生这种情况 import tkinter as tk from PIL import Image, ImageTk

您正在将登录按钮函数绑定到另一个从未调用过的函数中，并且您在这里编写的OOP错误。您不应该在init函数中定义函数。我不擅长解释，但我希望这会有所帮助。我在代码中也写了原因，在代码中我更改了代码
