Python - Tkinter 标签输出? [英] Python - Tkinter Label Output?

问题描述

我将如何从 Tkinter 获取我的条目，将它们连接起来，并将它们显示在下面的标签中(在输入例外:"旁边)?我只能在运行在 GUI 后面的 python 控制台中显示它们的输入.有没有办法在标签小部件中显示我的 InputExcept 变量?

from Tkinter import *主 = Tk()master.geometry('200x90')master.title('输入测试')定义用户名():usrE1 = usrE.get()usrN2 = usrN.get()InputExcept = usrE1 + " " + usrN2打印输入除外usrE = 条目(大师，救济=沉没)usrE.pack()usrN = 条目(大师，救济=沉没)usrN.pack()Btn1 = Button(文本=输入"，命令=用户名)Btn1.pack()lbl = Label(text='输入除外:')lbl.pack()master.mainloop()

解决方案

要做的两个主要步骤:

• 您需要将 usrE、usrE 和 lbl 声明为回调方法中的全局变量.
• 您需要使用

  注意:

  不要忘记指定在其上绘制标签和按钮的父小部件 (master).

  How would I take my entries from Tkinter, concatenate them, and display them in the Label below (next to 'Input Excepted: ')? I have only been able to display them input in the python console running behind the GUI. Is there a way my InputExcept variable can be shown in the Label widget?

  from Tkinter import *
  
  master = Tk()
  master.geometry('200x90')
  master.title('Input Test')
  
  def UserName():
      usrE1 = usrE.get()
      usrN2 = usrN.get()
      InputExcept = usrE1 + " " + usrN2
      print InputExcept 
  
  usrE = Entry(master, relief=SUNKEN)
  usrE.pack()
  
  usrN = Entry(master, relief=SUNKEN)
  usrN.pack()
  
  Btn1 = Button(text="Input", command=UserName)
  Btn1.pack()
  
  lbl = Label(text='Input Excepted: ')
  lbl.pack()
  
  master.mainloop()
  

  解决方案

  Two main steps to do:

  • You need to declare usrE, usrE and lbl as global variables inside your callback method.
  • You need to use config() method to update the text of lbl.

  Program:

  Here is the solution:

  from Tkinter import *
  
  master = Tk()
  master.geometry('200x90')
  master.title('Input Test')
  
  def UserName():
      global usrE
      global usrN
      global lbl
  
      usrE1 = usrE.get()
      usrN2 = usrN.get()
      InputExcept = usrE1 + " " + usrN2
      print InputExcept 
      lbl.config(text='User expected:'+InputExcept)
  
  
  usrE = Entry(master, relief=SUNKEN)
  usrE.pack()
  
  usrN = Entry(master, relief=SUNKEN)
  usrN.pack()
  
  Btn1 = Button(master, text="Input", command=UserName)
  Btn1.pack()
  
  lbl = Label(master)
  lbl.pack()
  
  master.mainloop()
  

  Demo:

  Running the program above will lead you to the expected result:

  Note:

  Do not forget to specify the parent widget (master) on which you draw the label and the button.
