* QMetaType: Fix compilation with non default constructible Q_GADGETOlivier Goffart2015-05-271-1/+1
| | | | | | | | | | | Do not try to automatically register the meta type for Q_GADGET that are not default constructible. This fixes a source incompatibility in the function pointer syntax of QObject::connect when such types are used as an argument of a signal.

* Add support for unregistering of custom meta types.Robert Griebl2015-04-141-0/+1
| | | | | | | | | | | | | This patch addresses a specific Qml problem, where the meta types list will grow indefinitely when unloading and reloading Qml components over and over (in an failed effort to save memory). The implementation is not specific to Qml though, but will cater to all use-cases where registered types may not live until the application's termination.

* Silence clang warnings in C++03 modeOlivier Goffart2015-04-011-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | C++03 forbid the use of local or unnamed type as template parameter. But in C++11 that is allowed, and clang accept them even in C++03 mode, but with a warning. The Warning happen for example with this code: enum { Foo = 3 }; int x = 3 << Foo; Then the compiler issues warnings: metatype.h:1379:31: warning: template argument uses local type [-Wlocal-type-template-args] enum { Value = sizeof(qt_getEnumMetaObject(declval())) == sizeof(QMetaObject*) }; ^~~~~~~~~~~~~~~~~~~~ qdebug.h:269:42: note: in instantiation of template class 'QtPrivate::IsQEnumHelper<(anonymous enum)>' requested here typename QtPrivate::QEnableIf<QtPrivate::IsQEnumHelper<T>::Value, QDebug>::Type operator<<(QDebug dbg, T value) Normaly the compiler should not even try to instantiate the operator<< with such types in C++03 mode.

* Fix source incompatibility while connecting signals with forward declared ↵Olivier Goffart2015-03-181-4/+4
| | | | | | | | | | | | | | | | | | | arguments QObject::connect tries to determine if the arguments are registered metatypes. This used to work even for arguments that were forward declared. But now, the metatype system tries to call QtPrivate::IsQEnumHelper<T>::Value to know if it is registered. That fails on gcc if T is forward declared. Apparently gcc needs to know the full type of T to pass it in the ellipsis function, even within a sizeof expression. So change the ellipsis expression to a template one.

* | Implement proper C++ type numeric promotion for QVariant comparisonsThiago Macieira2014-12-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, QVariant would try to convert one operand to the other's type, which would produce unexpected results: the results would depend in the order of the operands and whether there was data loss in the conversion. In addition, ordering comparisons were only done with signed values, yielding other unexpected results, like QVariant(LLONG_MAX / 2) < QVariant(Q_UINT64_C(0)). Instead, try to obey the C++ standard rules for type promotion in expressions. Our code is a little simpler than the standard would seem to require since we know some more details from the ABI. [ChangeLog][Important Behavior Changes][QVariant] QVariant now obeys the C++ type promotion rules when comparing numeric types (integrals, float and double), including the fact that unsigned comparisons are preferred for types of the same rank (that is, now QVariant(-1) > QVariant(0U)).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QMetaType::type(const char *) requires that the string argument is 0-terminated. This new overload makes it possible to query the type of a string with an explicit length. In particular, QByteArrays constructed by QByteArray::fromRawData(), for example from a substring of a normalized method signature (the "int" part of "mySlot(int"), can now be queried without making a copy of the string. Also, Qt5 meta-objects represent type names as QByteArray literals, which can be fed directly to this new QMetaType::type() overload (no need to call strlen).
