我只想创建一个程序,这样,当我单击“打印”按钮时,它将从输入字段中获取数据并输出到下面的文本字段中。我对.get()
的使用是否有问题?不确定是什么问题吗?
import tkinter as tk
from tkinter import *
wd=tk.Tk()
def inkq():
string= str(nd.get())
ketqua.insert(END, string)
nd=Entry(wd).pack()
btn=Button(wd, text ="Print", command = inkq).pack()
btn1=Button(wd, text ="Quit", command = wd.destroy).pack()
ketqua=Text(wd, height =10, width = 40).pack()
wd.mainloop()
答案 0 :(得分:1)
问题是.pack()返回None,它没有get方法。 从我运行代码后的以下错误打印中可以看出。
AttributeError:'NoneType'对象没有属性'get'
import tkinter as tk
from tkinter import *
wd=tk.Tk()
def inkq():
string= str(nd.get())
ketqua.insert(END, string)
nd=Entry(wd) #Save entry befor packing
nd.pack()
btn=Button(wd, text ="Print", command = inkq).pack()
btn1=Button(wd, text ="Quit", command = wd.destroy).pack()
ketqua=Text(wd, height =10, width = 40) #Save entry before packing
ketqua.pack()
wd.mainloop()
