You can check you model implementation with the QAbstractItemModelTester. See this wiki entry.

I'm sorry but I still don't get how you would like it to look

@michalos I'm not sure if I can help you but seems like model test code works for me. What I did: Added modeltest.h and cpp into my project Added "testlib" into "QT" section of project file Added this to modeltest.h: #include <QtTest/qtestcase.h> #define qVariantCanConvert(_type_, _var_) _var_.canConvert(QMetaType::_type_) Changed expressions like "qVariantCanConvert<QString> ( variant)" to "qVariantCanConvert(QString, variant)" in modeltest.h And... my sample model failed to pass the test of course :D
