Question

I\'m trying to do this with the check-box. Sadly is made for C++ and any adaptation of the code for Python has the result this error: \'QWidget\' object is not callabl

Answer 1

Here is an example from ekhumoro to find what is checked when it s being clicked :

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_())

But you can also iterate on your rows and use .findChild(type(QtGui.QCheckBox())).isChecked() on the proper column

such as :

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_())
