在这种情况下，我想填充且已修改为加载图像使用类TableWidgetImage如何使用QThread从慢Sql语句填充自定义QTableWidget？
from PyQt4 import QtGui
import sys
class ImageWidget(QtGui.QWidget):
def __init__(self, imagePath, parent):
super(ImageWidget, self).__init__(parent)
self.picture = QtGui.QPixmap(imagePath)
def paintEvent(self, event):
painter = QtGui.QPainter(self)
painter.drawPixmap(0, 0, self.picture)
class TableWidgetImage(QtGui.QTableWidget):
def setImage(self, row, col, imagePath):
image = ImageWidget(imagePath, self)
self.setCellWidget(row, col, image)
的功能是一个QTableWidget的：我从“cbUser”（帐户），选择一个项目我按下“btnCargar”和“tableSusAmigos”加载好。我的问题集中在下一步。当我双击单行到“tableSusAmigos”它应该加载第二个QTableWidget。有用。但我的问题是有很多行时。我想加载使用QThread。我不怎么修改使用QThread的UI QTableWidget控件。这是我的其他Python文件，它包含2个类：
class Ui_friendForm(QMdiSubWindow):
def __init__(self):
QtGui.QMdiSubWindow.__init__(self)
icon = QtGui.QIcon()
icon.addPixmap(QtGui.QPixmap(_fromUtf8(":/mmAmistad/mmAmistad.png")), QtGui.QIcon.Normal, QtGui.QIcon.Off)
self.setWindowIcon(icon)
self.resize(878, 637)

self.cbUser.setObjectName(_fromUtf8("cbUser"))
self.btnCargar = QtGui.QPushButton(self)
self.btnCargar.setGeometry(QtCore.QRect(250, 60, 91, 41))
icon = QtGui.QIcon()
icon.addPixmap(QtGui.QPixmap(_fromUtf8(":/picLoad/btnLoad.png")), QtGui.QIcon.Normal, QtGui.QIcon.Off)
self.btnCargar.setIcon(icon)
self.btnCargar.setObjectName(_fromUtf8("btnCargar"))

我将一张图片附加到我的应用程序中。提前致谢。
