Solved setData in ItemDelegate
-
I have a QTableView and created a QStyledItemDelegate to make the Cells editable. Everything works fine, but i have one Problem. When i edit the Cell the new Value will not be set in the Model and after editing it shows me the old Value. I think the Problem is the setData Method of the Model. Maybe i use the wrong Role, but i tried Qt::EditRole and Qt::DisplayRole. Here is my Code.
void MedisTableDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const { QLineEdit *editLine = static_cast<QLineEdit*>(editor); if (index.column() == 1 || index.column() == 8) { QString value = editLine->text(); model->setData(index, QVariant(value), Qt::DisplayRole); } else if (index.column() == 4) { QDate value = QDate::fromString(editLine->text(), "d. MMMM yyyy"); model->setData(index, value); } else if (index.column() == 2 || index.column() == 3) { int value = editLine->text().toInt(); model->setData(index, QVariant::fromValue(value)); } else QStyledItemDelegate::setModelData(editor, model, index); }
Someone has any Idea how to find the Problem? I outputed the new value with qDebug() and its always right. So there is something with the setData() Method. Maybe because i use an own Model?

@Fuel said in setData in ItemDelegate:
I think the Problem is the setData Method of the Model.
why not showing the code of it then?
-
euhm i didnt reimplement that Method in my Model. Is that the Problem?

@Fuel
what do you think? :)How should the model know how to set the data into your custom data structure.
