Before, in some cases + it was returned as an invalid type id, but sometimes it was used as a valid + type (C++ "void"). In Qt5, new QMetaType::UnknownType was introduced to + distinguish between these two. QMetaType::UnknownType is an invalid type id + signaling that a type is unknown to QMetaType, and QMetaType::Void + is a valid type id of C++ void type. The difference will be visible for + example in call to QMetaType::typeName(), this function will return null for + QMetaType::UnknownType and a pointer to "void" string for + QMetaType::Void. + Please, notice that QMetaType::UnknownType has value 0, which previously was + reserved for QMetaType::Void. + - QMessageBox |
