Description

After commit " QVariant: use a typedef name when saving user types to QDataStream" 46dc8e453ae1d0c1eb749cfebe686995f3a6cfd0 https://codereview.qt-project.org/c/qt/qtbase/+/373506 I'm seeing the following warning:

QMetaType: type QMap<int,QFlags<Qt::AlignmentFlag>> has more than one typedef alias: ColumnAlignmentMap, ColumnAlignmentMap

Example code:

using ColumnAlignmentMap = QMap<int, Qt::Alignment>;
Q_DECLARE_METATYPE(ColumnAlignmentMap)

ColumnAlignmentMap column_alignment1;
column_alignment1.insert(0, Qt::AlignCenter);
column_alignment1.insert(1, Qt::AlignRight);
column_alignment1.insert(2, Qt::AlignLeft);

QSettings s;
s.beginGroup("Test");
s.setValue("column_alignments", QVariant::fromValue<ColumnAlignmentMap>(column_alignment1));
ColumnAlignmentMap column_alignment2 = s.value("column_alignments").value<ColumnAlignmentMap>();
s.endGroup();
