我构建了一个消息传递应用程序,但似乎语法不正确:
from tkinter import messagebox
from AESEncDec import *
from MD5Hashing import *
from RSAEncDec import *
color = 'lightblue' #color our background
class Application(Frame):
def __init__(self, root=None):
Frame.__init__(self, root)
self.frame_width = 700
self.frame_height = 400
# Set configuration our frame
self.config(width = self.frame_width, height = self.frame_height, bg = color)
self.pack()
# Create textBox for input data
self.textbox_one = Text()
self.textbox_one.place(x = 30, y = 170, height = 200, width = 300 )
# Create textBox for result
self.textbox_two = Text()
self.textbox_two.place(x = 370, y = 170, height = 200, width = 300 )
label_input_text = Label( text = "Input text: ", bg = color)
label_input_text.place(x = 30, y = 155, height = 10, width = 70 )
在执行期间,我收到以下错误:
追踪(最近一次通话): 文件“/ home / artur / Documents / MScProject / MSc Project / Task#179276 / main_program.py”,第11行,in 类应用程序(框架): NameError:名称'Frame'未定义
可能是什么问题?
答案 0 :(得分:1)
Frame
是tkinter
模块中的一个类。
修复:
from tkinter import Frame
请参阅官方文档中的示例:https://docs.python.org/3.7/library/tkinter.html#a-simple-hello-world-program
您还需要导入Text
和Label
:
from tkinter import Frame
from tkinter import Text
from tkinter import Label
或者:
from tkinter import *
以下是修复代码的方法(我删除了未使用的导入):
import tkinter
color = 'lightblue' # color our background
class Application(tkinter.Frame):
def __init__(self, root=None):
super(Application, self).__init__(root)
self.frame_width = 700
self.frame_height = 400
# Set configuration our frame
self.config(width=self.frame_width, height=self.frame_height, bg=color)
self.pack()
# Create textBox for input data
self.textbox_one = tkinter.Text()
self.textbox_one.place(x=30, y=170, height=200, width=300)
# Create textBox for result
self.textbox_two = tkinter.Text()
self.textbox_two.place(x=370, y=170, height=200, width=300)
label_input_text = tkinter.Label(text="Input text: ", bg=color)
label_input_text.place(x=30, y=155, height=10, width=70)
root = tkinter.Tk()
app = Application(root)
app.mainloop()
