copied!<p>You should create a model that support Qt.CheckStateRole in data and SetData methods and the flag Qt.ItemIsUserCheckable in the flags method.</p> <p>I Paste you here an example i am using in a project, this is a QSortFilterProxyModel generic implementation to use in any model but you can use the same ideas in your model implementation, obviously i am using internal structures in this subclass you have not directly in PyQt and are attached to my internal implementation (self.booleanSet and self.readOnlySet).</p> <pre><code>def flags(self, index): if not index.isValid(): return Qt.ItemIsEnabled if index.column() in self.booleanSet: return Qt.ItemIsUserCheckable | Qt.ItemIsSelectable | Qt.ItemIsEnabled elif index.column() in self.readOnlySet: return Qt.ItemIsSelectable | Qt.ItemIsEnabled else: return QSortFilterProxyModel.flags(self, index) def data(self, index, role): if not index.isValid(): return QVariant() if index.column() in self.booleanSet and role in (Qt.CheckStateRole, Qt.DisplayRole): if role == Qt.CheckStateRole: value = QVariant(Qt.Checked) if index.data(Qt.EditRole).toBool() else QVariant(Qt.Unchecked) return value else: #if role == Qt.DisplayRole: return QVariant() else: return QSortFilterProxyModel.data(self, index, role) def setData(self, index, data, role): if not index.isValid(): return False if index.column() in self.booleanSet and role == Qt.CheckStateRole: value = QVariant(True) if data.toInt()[0] == Qt.Checked else QVariant(False) return QSortFilterProxyModel.setData(self, index, value, Qt.EditRole) else: return QSortFilterProxyModel.setData(self, index, data, role) </code></pre>
