Question

我在tkinter的python 3.6.2中编写了一个程序，我编写了以下代码：

from tkinter import *
root=Tk()
def retrieve_input():
    inputValue=textBox.get("1.0","end-1c")
    print(inputValue)

textBox=Text(root, height=2, width=10)
textBox.pack()
buttonCommit=Button(root, height=1, width=10, text="Commit", 
                    command=lambda: retrieve_input())
buttonCommit.pack()
mainloop()

我想按文本框中的Enter键打印“按文本框中的Enter键”。我怎么写事件？

检查此

from tkinter import *
from tkinter import messagebox

root=Tk()

def alertme(*args):
    messagebox.showinfo("Message", "you press Enter in textbox")

def retrieve_input():
    inputValue=textBox.get("1.0","end-1c")
    print(inputValue)

textBox=Text(root, height=2, width=10)
textBox.pack()

textBox.bind("<Return>", alertme) #this line calls alertme function whenever you press Enter key

buttonCommit=Button(root, height=1, width=10, text="Commit", 
                    command=lambda: retrieve_input())
buttonCommit.pack()
mainloop()

现在它只能在文本框内工作......

如何在tkinter中为文本框编写事件？
