Fixes an issue with generated code where the name of an enclosing
namespace is identical to an enum class type, when Q_ENUM_NS is used.
Consider:
namespace a {
Q_NAMESPACE
namespace b {
enum class b { Key, Key2 };
Q_ENUM_NS(b);
}
}
moc generated code such as:
Q_CONSTINIT const QMetaObject a:🅱️:staticMetaObject = { {
...
qt_incomplete_metaTypeArray<qt_meta_stringdata_CLASSaSCOPEbENDCLASS_t,
// enum 'TestEnum'
QtPrivate::TypeAndForceComplete<b::b, std::true_type>,
// Q_OBJECT / Q_GADGET
QtPrivate::TypeAndForceComplete<void, std::true_type>
>,
nullptr
} };
which confused the compiler:
error: ‘b’ is not a member of ‘a:🅱️:b
83 | QtPrivate::TypeAndForceComplete<b::b, std::true_type>,

If we don't have a valid Symbol to get a line number from, or if the

Change error/defaultErrorMsg/warning/note() to delegate to one central

note(), guarded against printing "-1" for the line number, whereas
error() didn't.

We had the code to calculate the length, but were improperly using it
only for the offset, not the length of the string or its containing
array. That resulted in the generated moc output containing:

QT_MOC_LITERAL(114, 5), // "\0012"
QT_MOC_LITERAL(117, 23), // "slotWithAReallyLongName"
The two strings are described as occupying 5 bytes (length 4 + null
terminator), which is incorrect. The offset was correct: 114 - 111 = 3
and 117 - 114 = 3. The new output is:
QT_MOC_LITERAL(111, 2), // "\xffz"
QT_MOC_LITERAL(114, 2), // "\0012"
QT_MOC_LITERAL(117, 23), // "slotWithAReallyLongName"
The effect of the array size calculation would only be felt if moc
decided it needed a second string array (for strings over 65535 bytes),
which would cause the offsets in the second array to be all wrong. There
was no such test until now.

Like Q_NAMESPACE_EXPORT for Q_NAMESPACE, this variant of Q_GADGET
allows passing an export macro. This is useful to avoid exporting the

Before anyone asks: No, we don't need Q_OBJECT_EXPORT, because QObject
subclasses, being polymorphic, always need to have a class-level
export macro (to export their vtable), but while that technique also
works for value classes (the Q_GADGET audience), it is not desirable
for them, because it makes inline functions exported in Windows debug
builds, which is not what we want, because it needlessly restricts
