PyQt4 and QTableView with spinbox and checkbox
- by ekapek
Hi,
I have a QTableView with QSqlTableModel and with 3 columns, now I need to have:
- second column: spinbox after clicked to edit
- third column: checkbox (displayed center)
My code:
class SpinBoxDelegate(QtGui.QItemDelegate):
def createEditor(self, parent, option, index):
editor = QtGui.QSpinBox(parent)
editor.setMinimum(0)
editor.setMaximum(100)
print 'spinbox'
return editor
def setEditorData(self, spinBox, index):
value = index.model().data(index, QtCore.Qt.EditRole).toInt()[0]
spinBox.setValue(value)
def setModelData(self, spinBox, model, index):
spinBox.interpretText()
value = spinBox.value()
model.setData(index, value, QtCore.Qt.EditRole)
def updateEditorGeometry(self, editor, option, index):
editor.setGeometry(option.rect)
class myQSqlTableModel(QtSql.QSqlTableModel):
def flags(self,index):
result = QtSql.QSqlTableModel.flags(self,index);
if index.column() == 2:
result |= QtCore.Qt.ItemIsUserCheckable
return result
def data(self,index,role):
if not index.isValid: return QtCore.QVariant()
value = QtSql.QSqlTableModel.data(self, index, role)
if index.column() == 2:
if role == QtCore.Qt.CheckStateRole:
return QtCore.Qt.Unchecked if QtSql.QSqlTableModel.data(self, index).toInt()[0] else QtCore.Qt.Checked
elif role == QtCore.Qt.DisplayRole:
return QtCore.QVariant()
return value
and
self.model = myQSqlTableModel(self)
self.model.setTable("person")
self.model.setEditStrategy(QtSql.QSqlTableModel.OnManualSubmit)
self.model.select():
self.model.setHeaderData(0, QtCore.Qt.Horizontal,
self.tr("ID"))
self.model.setHeaderData(1, QtCore.Qt.Horizontal,
self.tr("A"))
self.model.setHeaderData(2, QtCore.Qt.Horizontal,
self.tr("B"))
self.view = QtGui.QTableView()
self.view.setModel(self.model)
self.view.setSortingEnabled(True)
spinDelegate = SpinBoxDelegate()
self.view.setItemDelegateForColumn(1,spinDelegate)
but it does't work: spinbox don't show after click and checkbox can't be clicked and is aligned to left
Any help?
