Question

我正在使用QTableWidget来显示csv数据。当我输入关键字时，我希望执行类似于excel的过滤操作。它应该影响所有的行和列。

from PyQt4 import QtCore, QtGui, uic
from PyQt4.QtCore import QString

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

import MySQLdb
import os
import time
import sys
import hashlib
import getpass
import webbrowser
import csv

filter_class = uic.loadUiType("filter.ui")[0]

class Filter_window(QtGui.QWidget, filter_class):
    def __init__(self, parent=None, *args, **kwargs):
        QtGui.QMainWindow.__init__(self, parent)
        self.setupUi(self)

        #self.selectall.clicked.connect(self.selectall_application)
        #self.filnext.clicked.connect(self.filnext_application)

         self.loadAll()


    def loadAll(self):

        with open("Rts.csv", "rb") as inpfil:

            reader = csv.reader(inpfil, delimiter = ',')
            csheader = reader.next()
            ncol = len(csheader)
            data = list(reader)
            row_count = len(data)

            self.filterall.setRowCount(row_count)
            self.filterall.setColumnCount(ncol)
            self.filterall.setHorizontalHeaderLabels(QString('%s' % ', '.join(map(str, csheader))).split(","))

            for ii in range(0, row_count):
                print data[ii]

                mainins = data[ii]
                print mainins


                for var in range(0,ncol):                                                  
                    print mainins[var], "\n"
                    self.filterall.setItem(ii, var, QTableWidgetItem(mainins[var]))


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    filterwin = Filter_window()
    filterwin.show()
    sys.exit(app.exec_())

filterall是对象名称为QTableWidget
