如何使用pyqt在表中顯示mysql數據庫中的數據？

Question

我在mysql數據庫中有一些數據，我想用pyqt將它顯示到表中， 這是來自數據庫（SELECT * FROM MONITORING）的查詢。 幫助我顯示錶格小部件內的數據庫內容。

這裏是我的程序源代碼：

from PyQt4 import QtCore, QtGui 
import sys 
import MySQLdb 
from form.DBConnection import Connection 
import MySQLdb as mdb 

db = Connection() 
myCursor = db.name().cursor() 
try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
     return s 

try: 
    _efncoding = QtGui.QApplication.UnicodeUTF8 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig, _encoding) 
except AttributeError: 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig) 

class Ui_MainWindow(object): 
    def setupUi(self, MainWindow): 
     MainWindow.setObjectName(_fromUtf8("MainWindow")) 
     MainWindow.resize(655, 356) 
     self.centralwidget = QtGui.QWidget(MainWindow) 
     self.centralwidget.setObjectName(_fromUtf8("centralwidget")) 
     self.tbl_anggota = QtGui.QTableWidget(self.centralwidget) 
     self.tbl_anggota.setGeometry(QtCore.QRect(15, 40, 511, 192)) 
     self.tbl_anggota.setObjectName(_fromUtf8("tbl_anggota")) 
     self.tbl_anggota.setColumnCount(5) 
     self.tbl_anggota.setRowCount(0) 
     item = QtGui.QTableWidgetItem() 
     self.tbl_anggota.setHorizontalHeaderItem(0, item) 
     item = QtGui.QTableWidgetItem() 
     self.tbl_anggota.setHorizontalHeaderItem(1, item) 
     item = QtGui.QTableWidgetItem() 
     self.tbl_anggota.setHorizontalHeaderItem(2, item) 
     item = QtGui.QTableWidgetItem() 
     self.tbl_anggota.setHorizontalHeaderItem(3, item) 
     item = QtGui.QTableWidgetItem() 
     self.tbl_anggota.setHorizontalHeaderItem(4, item) 
     self.bt_hapus = QtGui.QPushButton(self.centralwidget) 
     self.bt_hapus.setGeometry(QtCore.QRect(350, 250, 75, 23)) 
     self.bt_hapus.setObjectName(_fromUtf8("bt_hapus")) 
     MainWindow.setCentralWidget(self.centralwidget) 
     self.menubar = QtGui.QMenuBar(MainWindow) 
     self.menubar.setGeometry(QtCore.QRect(0, 0, 655, 21)) 
     self.menubar.setObjectName(_fromUtf8("menubar")) 
     MainWindow.setMenuBar(self.menubar) 
     self.statusbar = QtGui.QStatusBar(MainWindow) 
     self.statusbar.setObjectName(_fromUtf8("statusbar")) 
     MainWindow.setStatusBar(self.statusbar) 

     self.retranslateUi(MainWindow) 
     QtCore.QMetaObject.connectSlotsByName(MainWindow) 

    def retranslateUi(self, MainWindow): 
     MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None)) 
     item = self.tbl_anggota.horizontalHeaderItem(0) 
     item.setText(_translate("MainWindow", "nim", None)) 
     item = self.tbl_anggota.horizontalHeaderItem(1) 
     item.setText(_translate("MainWindow", "nama", None)) 
     item = self.tbl_anggota.horizontalHeaderItem(2) 
     item.setText(_translate("MainWindow", "jabatan", None)) 
     item = self.tbl_anggota.horizontalHeaderItem(3) 
     item.setText(_translate("MainWindow", "email", None)) 
     item = self.tbl_anggota.horizontalHeaderItem(4) 
     item.setText(_translate("MainWindow", "nohp", None)) 
     self.bt_hapus.setText(_translate("MainWindow", "Hapus", None)) 


if __name__ == "__main__": 
    app = QtGui.QApplication(sys.argv) 
    MainWindow = QtGui.QMainWindow() 
    ui = Ui_MainWindow() 
    ui.setupUi(MainWindow) 
    MainWindow.show() 
    sys.exit(app.exec_())

我這是怎麼做到這一點：

import sqlite3 as lite 
... 
cur = self.SQLiteDB.cursor() 
cur.execute("SELECT * FROM SQLTable") 
allSQLRows= cursor.fetchall() 
self.myTableWidget.setRowCount(len(allSQLRows)) ##set number of rows 
self.myTableWidget.setColumnCount(8) ##this is fixed for myTableWidget, ensure that both of your tables, sql and qtablewidged have the same number of columns 

row = 0 
while True: 
    sqlRow = cur.fetchone() 
    if sqlRow == None: 
     break ##stops while loop if there is no more lines in sql table 
    for col in range(0, 8): ##otherwise add row into tableWidget 
     self.myTableWidget.setItem(row, col, QtGui.QTableWidgetItem(sqlRow[col])) 
    row += 1
