The QMetaType class manages named types in the meta-object system. The class is used as a helper to marshall types in QVariant and in queued signals and slots connections. It associates a type name to a type so that it can be created and destructed dynamically at run-time. [SOLVED] SIGNAL/SLOT cannot work with Qt:QueuedConnection ...

Creating Custom Qt Types | Qt 4.8 Standard types such as QSize, QColor and QString can all be stored in QVariant objects, used as the types of properties in QObject-based classes, and emitted in signal-slot communication. In this document, we take a custom type and describe how to integrate it into Qt's object model so that it can be stored in the same way as standard Qt types. Queued Custom Type Example | Qt Core 5.12.3 Contents: Overview.
