Description
I have a first library that defines a namespace like:
namespace WarningState
{
Q_NAMESPACE_EXPORT(HELPLIB_EXPORT)
enum class State
{
Unknown,
Information,
Warning,
Error,
Success
};
Q_ENUM_NS(State);
} // namespace WarningState
Then In a QML reusable module, I want to register it to be able to use the enum in QML code.
For that I added this to my module:
namespace WarningStateForeign
{
Q_NAMESPACE
QML_NAMED_ELEMENT(WarningState)
QML_FOREIGN_NAMESPACE(WarningState)
};
The code generated does not build.
Here is the generated code:
Q_QMLTYPE_EXPORT void qml_register_types_Help()
{
qmlRegisterTypesAndRevisions<HelpNotificationListModelForeign>("Help", 1);
QMetaType::fromType<WarningState>().id();
qmlRegisterNamespaceAndRevisions(&WarningState::staticMetaObject, "Help", 1, nullptr, &WarningStateForeign::staticMetaObject, nullptr);
qmlRegisterModule("Help", 1, 0);
}
The error is on line
QMetaType::fromType<WarningState>().id();
WarningState is an enum. If I remove this line of code it works correctly and everything is correctly registered to QML.
If I move the namespace definition in the QML module (instead of beeing in a separated library) it also works.
