[python]示範如何使用tkinter的text widget

2.如何從頭插入，從尾插入以及取得整個text當中的內容

import Tkinter as tk
class Mainapplication(tk.Frame):
 def __init__(self,master=None):
  tk.Frame.__init__(self,master)
  self.pack()
  self.createwidget()
  
 def createwidget(self):
  self.label = tk.Label(self,text="hello world")
  self.label.pack()
  self.text = tk.Text(self,height=5)
  self.text.pack()
  self.button = tk.Button(self,text="OK",command=self.addcontent)
  self.button.pack()
  self.button2 = tk.Button(self,text="OK2",command=self.addcontent2)
  self.button2.pack()
  self.button3 = tk.Button(self,text="OK2",command=self.addcontent3)
  self.button3.pack()
 
 #將文字插入最前面(insert)
 def addcontent(self):
  self.text.insert(1.0,"OK\n")
 
 #將文字插入最後
 def addcontent2(self):
  self.text.insert(tk.END,"NO")
 
 #取得整個text當中的內容(get)
 def addcontent3(self):
  temp = self.text.get(1.0,tk.END)
  print temp

if __name__ =='__main__':
 root = tk.Tk()
 application = Mainapplication(master=root)
 root.mainloop()

Tkinter 加法

from tkinter import *
from tkinter.messagebox import *

def show_answer():
   Ans = int(num1.get()) + int(num2.get())
   blank.insert(0, Ans)


main = Tk()
main.title("Tkinter 加法 A+B ")
main.geometry("300x200")

Label(main, text = "Enter Num 1:").grid(row=0)
Label(main, text = "Enter Num 2:").grid(row=1)
Label(main, text = "The Sum is:").grid(row=2)


num1 = Entry(main)
num2 = Entry(main)
blank = Entry(main)


num1.grid(row=0, column=1)
num2.grid(row=1, column=1)
blank.grid(row=2, column=1)


Button(main, text='Quit', command=main.destroy).grid(row=4, column=0, sticky=W, pady=4)
Button(main, text='Show', command=show_answer).grid(row=4, column=1, sticky=W, pady=4)

mainloop()

Tkinter Text Entry / Text Show

main = Tk()
Label(main, text = "Enter Num 1:").grid(row=0, column=1)
Label(main, text = "Enter Num 2:").grid(row=1, column=1)
Label(main, text = "The Sum is:").grid(row=2, column=1)


num1 = Entry(main)
num2 = Entry(main)
blank = Entry(main)


num1.grid(row=0, column=2)
num2.grid(row=1, column=2)
blank.grid(row=2, column=2)


Button(main, text='Quit', command=main.quit).grid(row=4, column=1, sticky=W, pady=4)
Button(main, text='Show', command=show_answer).grid(row=4, column=2, sticky=W, pady=4)
