copied!<p>Note: The answer of Dave works also for Python using PySide or PyQt4. I translated it, and it works great. Additionally, I added the functionality that the checkbox does not accept user input and is shown in a ReadOnly state if the cell is not editable. Thanks Dave for your code!</p> <pre><code>class CheckBoxDelegate(QStyledItemDelegate): def createEditor(self, parent, option, index): ''' Important, otherwise an editor is created if the user clicks in this cell. ''' return None def paint(self, painter, option, index): ''' Paint a checkbox without the label. ''' checked = bool(index.model().data(index, Qt.DisplayRole)) check_box_style_option = QStyleOptionButton() if (index.flags() & Qt.ItemIsEditable) > 0: check_box_style_option.state |= QStyle.State_Enabled else: check_box_style_option.state |= QStyle.State_ReadOnly if checked: check_box_style_option.state |= QStyle.State_On else: check_box_style_option.state |= QStyle.State_Off check_box_style_option.rect = self.getCheckBoxRect(option) if not index.model().hasFlag(index, Qt.ItemIsEditable): check_box_style_option.state |= QStyle.State_ReadOnly QApplication.style().drawControl(QStyle.CE_CheckBox, check_box_style_option, painter) def editorEvent(self, event, model, option, index): ''' Change the data in the model and the state of the checkbox if the user presses the left mousebutton or presses Key_Space or Key_Select and this cell is editable.
