Description
Consider the following class definition:
#include <QObject>
enum class FOO { BAR };
class Exported: public QObject {
Q_OBJECT
public:
using QObject::QObject;
using FOO = ::FOO;
Q_ENUM(FOO)
};
Exported to the QML environment as it follows:
qmlRegisterType<Exported>("Package", 1, 0, "Exported");
We can't use the named constant as usual, that is:
import Package 1.0
// ...
Exported.BAR
On the other side, the following works fine:
class Exported: public QObject {
Q_OBJECT
public:
using QObject::QObject;
enum class FOO { BAR };
Q_ENUM(FOO)
};
As weel as this one:
class Exported: public QObject {
Q_OBJECT
public:
using QObject::QObject;
enum class FOO;
Q_ENUM(FOO)
enum class FOO { BAR };
};
In other terms using declarations, even though they import a set of names into their declarative regions, are not treated as enum declarations.
Documentations is misleading. If the issue can't be solved, the docs should be updated at least.
