Question

我正在使用python tkinter GUI。我的问题是当我在ScrolledText小部件中插入大量数据（大于200 KB）时，thinter gui挂起。有没有解决办法用tkinter GUI处理大量数据？

这是我的代码：

import Tkinter
from Tkinter import * 
import tkFileDialog
from tkMessageBox import showinfo, showerror 
from ScrolledText import ScrolledText 
import codecs
import random

class GUI_Window():
    '''
        GUI Class 
    '''
    def init(self):        
        self.__m_top = Tkinter.Tk()


        self.lab1 = Tkinter.Label(self.__m_top, font = "{Courier} 10 {bold}" ,text = "Data")
        self.lab1.pack()
        self.lab1.place(bordermode=OUTSIDE, height=25, width=40,x=10,y=20)

        self.__i_txtnm="Data Window"
        self.__Data_window_txt = ScrolledText(self.__m_top, undo=False,height=5,width=4)
        self.__Data_window_txt['font'] = ('Times New Roman', '10')
        self.__Data_window_txt.bind("<Control-Key-a>", lambda event, arg=self.__i_txtnm: self.__select_alldata(event, arg))
        self.__Data_window_txt.pack(expand=False, fill='both')
        self.__Data_window_txt.place(bordermode=OUTSIDE,height=450,width=400,x=10,y=40)


        self.lab1 = Tkinter.Label(self.__m_top, font = "{Courier} 10 {bold}" ,text = "Data Size")
        self.lab1.pack()
        self.lab1.place(bordermode=OUTSIDE, height=25, width=100,x=100,y=500)


        self.tfield = Tkinter.Text(self.__m_top,font = "{Courier} 10 {normal}",width = 82,height = 20,background = 'white', foreground = 'black')
        self.tfield.pack()
        self.tfield.place(bordermode=OUTSIDE, height=25, width=90,x=190,y=500)

        self.lab2 = Tkinter.Label(self.__m_top, font = "{Courier} 10 {bold}" ,text = "KB")
        self.lab2.pack()
        self.lab2.place(bordermode=OUTSIDE, height=25, width=20,x=290,y=500)


        self.__btnText="Generate Data"
        self.__gen_Data_btn=Tkinter.Button(self.__m_top, text = "Generate Data", command =lambda: self.__generate_btn_click() , width = 10)
        self.__gen_Data_btn.pack()
        self.__gen_Data_btn.place(bordermode=OUTSIDE, height=25, width=90,x=140,y=550)

        self.__btnText="Clear Data"
        self.__gen_Data_btn=Tkinter.Button(self.__m_top, text = "Clear Data", command =lambda: self.__claerData() , width = 10)
        self.__gen_Data_btn.pack()
        self.__gen_Data_btn.place(bordermode=OUTSIDE, height=25, width=90,x=240,y=550)


        self.__m_top.wm_title('My Data Window')
        self.__m_top.geometry("450x650")
        self.__m_top.resizable('0', '0')
        self.__m_top.mainloop()
        #self.__browse_sendFilepath_txt.insert(INSERT,file.name)



    def __generate_btn_click(self):

        data_Size=self.tfield.get("1.0", END)
        try:
            data_Size= int(data_Size)
            data=self.__genrateData(data_Size)
            self. __Data_window_txt.insert(INSERT, data)
        except:
            showerror('Set Config', 'Plesase Insert Numeric Value')

    def __select_alldata(self,event,i_txtnm):
            self.__Data_window_txt.tag_add(SEL, "1.0", END)
            self.__Data_window_txt.mark_set(INSERT, "1.0")
            self.__Data_window_txt.see(INSERT)


    def __genrateData(self,i_size):  

        data=''
        for i in range(1024*i_size):
            data+=random.choice("abcdefghijklmnopqrstuvwxyz")

        return data

    def __claerData(self):
        self.__Data_window_txt.delete(1.0, END)


if __name__ == "__main__":
    g1=GUI_Window()
    g1.init()

在scrolledtext中插入大量数据时，tkinter gui崩溃
