Question

我有应用程序检查日期（linux）并将此'日期'放入单元格'a1'。如何在应用程序运行一分钟后刷新单元格'a1'？将来我将刷新下面列出的所有单元格，但在开始时很好知道如何刷新第一个单元格;] 应用程序将在linux（而不是Windows）下运行。

import sys 
import os

from PyQt4.QtCore import * 
from PyQt4.QtGui import *
from PyQt4 import QtCore, QtGui

#!/usr/bin/python

a1 = os.popen("date")
a1 = a1.read()

data = {'date':['%s'%a1,'a2','a3'], 'x1':['b1','b2','b3'], 'x2':['c1','c2','c3'], 'x3':['d1','d2','d3'], 'x4':['e1','e2','e3'], 'min':['f1','f2','f3'], 'x5':['g1','g2','g3'], 'x6':['h1','h2','h3']}

class MyTable(QTableWidget): 

    def __init__(self, data, *args): 
        QTableWidget.__init__(self, *args) 
        self.data = data 
        self.setmydata()
        self.resizeColumnsToContents() 
        self.resizeRowsToContents()

    def setmydata(self):
        horHeaders = []
        for n, key in enumerate(sorted(self.data.keys())):  
          horHeaders.append(key) 
          for m, item in enumerate(self.data[key]): 
               newitem = QTableWidgetItem(item) 
               self.setItem(m, n, newitem) 
         self.setHorizontalHeaderLabels(horHeaders)


    def main(args): 
        app = QApplication(args) 
        table = MyTable(data, 5, 8) 
        table.show() 
        sys.exit(app.exec_())   

if __name__=="__main__": 
    main(sys.argv)
