PyQt 对齐复选框并将其放在每一行中

我正在尝试做this http://falsinsoft.blogspot.ro/2013/11/qtablewidget-center-checkbox-inside-cell.html与复选框。 遗憾的是，它是为 C++ 编写的，并且对 Python 代码的任何改编都会导致以下错误：'QWidget' object is not callable我想做的是在每一行添加一个复选框，这是我的代码：

    pWidget = QWidget()
    pCheckbox = QCheckBox()
    pLayout = QVBoxLayout()
    pLayout.addWidget(pCheckbox)
    pLayout.setAlignment(Qt.AlignCenter)
    pLayout.setContentsMargins(0, 0 ,0, 0)
    pWidget.setLayout(pLayout)

    for char in accounts:
        for columnNumber in range(numberColumns):
            chkBoxItem = QTableWidgetItem()
            chkBoxItem.setFlags(Qt.ItemIsUserCheckable | Qt.ItemIsEnabled)
            chkBoxItem.setCheckState(Qt.Unchecked)
            self.mainAccountTable.insertRow(currentRowCount)
            self.mainAccountTable.setItem(currentRowCount, 0, pWidget(chkBoxItem))
            self.mainAccountTable.setItem(currentRowCount, 1, QTableWidgetItem(data[1]))

如果我把pLayout = Layout()是说它没有用Python实现。 那么，如何添加居中对齐的复选框而不在每行附近添加文本区域？预先感谢您的任何提示。

稍后编辑： 将代码移动到循环内是有效的，但我无法控制检查：

for char in accounts:
        for columnNumber in range(numberColumns):
            pWidget = QWidget()
            pCheckbox = QCheckBox()
            pLayout = QVBoxLayout(pWidget)
            pLayout.addWidget(pCheckbox)
            pLayout.setAlignment(Qt.AlignCenter)
            pLayout.setContentsMargins(0, 0 ,0, 0)
            pWidget.setLayout(pLayout)
            #chkBoxItem = QTableWidgetItem()
            #chkBoxItem.setFlags(Qt.ItemIsUserCheckable | Qt.ItemIsEnabled)
            #chkBoxItem.setCheckState(Qt.Unchecked)
            self.mainAccountTable.insertRow(currentRowCount)
            self.mainAccountTable.setCellWidget(currentRowCount, 0, pWidget)

这是一个截屏 https://i.stack.imgur.com/Valii.jpg我如何知道我检查了什么并构建设置列表？

Here is ekhumoro 的一个例子 https://stackoverflow.com/a/12373320/984421查找单击时检查的内容：

from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        QtGui.QWidget.__init__(self)
        self.table = QtGui.QTableWidget(rows, columns, self)
        for column in range(columns):
            for row in range(rows):
                item = QtGui.QTableWidgetItem('Text%d' % row)
                if row % 2:
                    item.setFlags(QtCore.Qt.ItemIsUserCheckable |
                                  QtCore.Qt.ItemIsEnabled)
                    item.setCheckState(QtCore.Qt.Unchecked)
                self.table.setItem(row, column, item)
        self.table.itemClicked.connect(self.handleItemClicked)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.table)
        self._list = []

    def handleItemClicked(self, item):
        if item.checkState() == QtCore.Qt.Checked:
            print('"%s" Checked' % item.text())
            self._list.append(item.row())
            print(self._list)
        else:
            print('"%s" Clicked' % item.text())

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(6, 3)
    window.resize(350, 300)
    window.show()
    sys.exit(app.exec_())

但您也可以迭代行并使用.findChild(type(QtGui.QCheckBox())).isChecked()在正确的列上

例如 ：

from PyQt4 import QtGui, QtCore
from PyQt4.QtCore import Qt

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        QtGui.QWidget.__init__(self)
        self.table = QtGui.QTableWidget(rows, columns, self)
        for row in range(rows):
            qwidget = QtGui.QWidget()
            checkbox = QtGui.QCheckBox()
            checkbox.setCheckState(QtCore.Qt.Unchecked)
            qhboxlayout = QtGui.QHBoxLayout(qwidget)
            qhboxlayout.addWidget(checkbox)
            qhboxlayout.setAlignment(Qt.AlignCenter)
            qhboxlayout.setContentsMargins(0, 0, 0, 0)
            self.table.setCellWidget(row, 0, qwidget)
            self.table.setItem(row, 1, QtGui.QTableWidgetItem(str(row)))
        layout = QtGui.QVBoxLayout(self)
        self.button = QtGui.QPushButton()
        self.button.setObjectName("loadButton")
        layout.addWidget(self.table)
        layout.addWidget(self.button)
        self.button.clicked.connect(self.ButtonClicked)

    def ButtonClicked(self):
        checked_list = []
        for i in range(self.table.rowCount()):
            if self.table.cellWidget(i, 0).findChild(type(QtGui.QCheckBox())).isChecked():
                checked_list.append(self.table.item(i, 1).text())
        print checked_list


if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(3, 2)
    window.resize(350, 300)
    window.show()
    sys.exit(app.exec_())
