How to create attribute for QStrandardItem?

[tyapkov]

Good evening! I am using QStandardItemModel for the QTreeView and want to set hidden attributes for the QStandardItems to distinguish them. Is there a good solution for that? thanks!

You can define your own "Qt::ItemDataRoles":/doc/qt-4.8/qt.html#ItemDataRole-enum and use data() and setData() methods of the items.

For example:

@
enum MyItemDataRoles { MyIdRole = Qt::UserRole + 1, MyStringDataRole };

QStandardItem *item = ...;

item->setData(23, MyIdRole);
int id = item->data(MyIdRole).toInt();

item->setData("blubb", MyStringDataRole);
qDebug() << item->data(MyStringDataRole).toString();
