Python弹出输入框并获取输入值的实例

from Tkinter import *
import tkMessageBox
 
 
def getInput(title, message):
  def return_callback(event):
    print('quit...')
    root.quit()
  def close_callback():
    tkMessageBox.showinfo('message', 'no click...')
  root = Tk(className=title)
  root.wm_attributes('-topmost', 1)
  screenwidth, screenheight = root.maxsize()
  width = 300
  height = 100
  size = '%dx%d+%d+%d' % (width, height, (screenwidth - width)/2, (screenheight - height)/2)
  root.geometry(size)
  root.resizable(0, 0)
  lable = Label(root, height=2)
  lable['text'] = message
  lable.pack()
  entry = Entry(root)
  entry.bind('<Return>', return_callback)
  entry.pack()
  entry.focus_set()
  root.protocol("WM_DELETE_WINDOW", close_callback)
  root.mainloop()
  str = entry.get()
  root.destroy()
  return str
