Problem with QStringListModel and data for Qt::UserRole

[Wurgl]

I tried a QStringListModel for filling some model for a QComboBox, but failed with setting additional data with the role Qt::UserRole (same with Qt::UserRole+1). This is somehow unexpected.

As a solution, I could change it to QStandardItemModel, but I thought to use this time something different.

Qt-Version is 5.4.2 (same with Qt 4.8.2)

An example-snipplet to reproduce:

#include <QStringListModel>
#include <QDebug>

int main(int argc, char *argv[])
{
  QStringListModel *m = new QStringListModel();
  m->insertRow(0);
  qDebug() << "m has" << m->rowCount() << "rows";

  m->setData(m->index(0, 0), "Text"); // works fine
  qDebug() << "item text is" << m->data(m->index(0, 0), Qt::EditRole);

  m->setData(m->index(0, 0), "Data", Qt::UserRole); // does not work as expected
  qDebug() << "item data is" << m->data(m->index(0, 0), Qt::UserRole);

  m->setData(m->index(0, 0), "modified Text"); // works fine
  qDebug() << "item text is" << m->data(m->index(0, 0), Qt::EditRole);
  return 0;
}

@Wurgl
QStringListModel::setData() only handles DisplayRole and EditRole.
The other roles are simply ignored.

Just checked the documentation, but (so far) did not find any hint there. Shouldn't this be in the documentation?

yes it should probably.
If you like you can create a request in the bugtracker (for "Documentation" component)

Solved for me … thanks!
