Detailed Description

Drag drop support is limited to passsing data types supported by the tree-widget default handlers. To pass pointers as user data, use reinterpret_cast to pass them as uLongLong, for example:

Data* dataPtr = getData();
item->setData(Column::Name, Qt::UserRole, QVariant::fromValue(reinterpret_cast<uintptr_t>(dataPtr)));
Data* restoredData = reinterpret_cast<Data*>(item->data(Column::Name, Qt::UserRole).toULongLong());
