* Improve connect: Use existing metatypes if possibleFabian Kosmale2020-08-281-0/+27
| | | | | | | | | | | As there is now a chance that a QMetaMethod already contains the metatypes for its arguments, we can just query it directly (and use the fallback to name lookup logic that already exists there). This also allows us to avoid creating a QList of names, and only requires us to do a name lookup in case the connection actually fails.

| | | | | | | | | | | | | And remove one of the type id to name mapping that still existed in QMetaType. QMetaTypeInterface can provide that, so there's no need to have a second copy of the data. qMetaTypeTypeInternal() can still map all the names of all builtin types to ids. That functionality is for now still required by moc and can't be removed yet. Change-Id: Ib4f8e9c71e1e7d99d52da9e44477c9a1f1805e57 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* MetaObject: Store the QMetaType of the methodsFabian Kosmale2020-06-021-4/+61
| | | | | | | | | | | | | | | | | | | | | | | | This does the analog of 46f407126ef3e94d59254012cdc34d6a4ad2faf2 for the methods we care about (signals, slots, Q_INVOKABLEs). In addition to the actual QMetaType, we store an array with offsets so that we later can do a mapping from methodIndex to metatype. The newly added QMetaMethod::{return,parameter}MetaType methods can then be used to retrieve the metatypes. This does however require that all involved types are complete. This is unfortunately not a feasible requirement. Thus, we only populate the metatype array on a best effort basis. For any incomplete type, we store QMetaType::Unknown. Then, when accessing the metatype, we fall back to the old string based code base if it's Unknown.

* Core/kernel: Make some signals private.Stephen Kelly2012-10-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | There are more opportunities in QtCore and the rest of Qt to make signals private instead of public. This is a test-dart to see if there is any reason not to do this. It would be nice to make QObject::destroyed private, but as it has a default argument it would be source incompatible to anyone connecting to the SIGNAL(destroyed()) instead of SIGNAL(destroyed(QObject*)). Currently the function-pointer-based connect syntax does not accept a functor (or lambda) with a different number of arguments than the signal. Olivier says a fix for that might come in 5.1, but for now the qfiledialog2 test is changed to not use that anymore. Also, the function pointer for a private signal can not be assigned to a local variable, so the qmetamethod test is changed to not do so anymore.

* QMetaMethod::typeName() should return "void" if the return type is voidKent Hansen2012-03-211-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QMetaMethod::typeName() is documented to return an empty string if the return type is void. But after the introduction of QMetaType::UnknownType (where void was made a distinct type), returning an empty string causes the idiom QMetaType::type(method.typeName()) to break; the result will be QMetaType::UnknownType rather than the expected QMetaType::Void for methods that return void. New code should use the new function QMetaMethod::returnType() instead, but it would be good if existing code still did the right thing. The consequence of returning "void" instead of an empty string is that it breaks existing logic that uses the typeName() length to determine whether a method returns void. But we judge this as the lesser of the two evils; it's better to have a typeName() function that is consistent and keeps the QMetaType::type(method.typeName()) idiom working, than to force the typeName() inconsistency for void only to keep code that does "strlen(method.typeName()) == 0" working. The places in Qt that were relying on a zero-length typeName() (testlib, dbus, declarative) have already been changed to use returnType(). Also adapt QMetaObjectBuilder, which is internal API.

| | | | | | | | | | | | | | | | | QMetaType::Void was ambiguous, it was pointing to a valid type (void) and in the same time it was signaling errors in QMetaType. There was no clean way to check if returned type was valid void or some unregistered type. This feature will be used by new QMetaObject revision which will store type ids instead of type names.

* Long live Qt5 meta-object method/property descriptorsKent Hansen2012-02-291-4/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces two significant changes to the meta-object data format: 1) Meta-type information (QMetaType type/name) information is stored directly in the meta-data for both properties and methods; 2) The original signature (string) of a method is no longer stored in the meta-data, since it can be reconstructed from the method name and parameter type info. The motivation for this change is to enable direct access to method names and type information (avoiding string-based lookup for types if possible), since that's typically the information language bindings (e.g. QML) need. (moc already had all the desired information about methods, but it threw it away!) This change keeps support for the older (6 and below) meta-object revisions, but the support will be removed after a short grace period. The following public QMetaMethod functions have been added: name() : QByteArray returnType() : int parameterCount() : int parameterType(int index) : int The following internal QMetaMethod function has been added: getParameterTypes(int *types) : void This commit extends the meta-method data to include explicit type/name data for methods. The new data follows the existing (5-word) method descriptors in the meta-data. The method descriptor format was modified to enable this. First, the descriptor now contains the meta-data index where the method's type/name information can be found. Second, the descriptor contains the number of parameters. Third, the descriptor has a reference to the name of the method, not the full signature. Each entry of a method's type/name array contains either the type id (if it could be determined at meta-object definition time), or a reference to the name of the type (so that the type id can be resolved at runtime). Lastly, instead of storing the method parameter names as a comma-separated list that needs to be parsed at runtime (which was how it was done prior to this commit), the names are now stored as separate entries in the meta-object string table, and their indexes are stored immediately after the method type info array. Hence, parameter names can be queried through the public API without parsing/allocating/copying, too.

* Rename QMetaMethod::signature() to methodSignature()Kent Hansen2012-02-291-1/+1
| | | | | | | | | | | | | | | | | | | | In Qt5 the meta-data format will be changed to not store the method signature string explicitly; the signature will be reconstructed on demand from the method name and parameter type information. The QMetaMethod::signature() method returns a const char pointer. Changing the return type to QByteArray can lead to silent bugs due to the implicit conversion to char *. Even though it's a source- incompatible change, it's therefore better to introduce a new function, methodSignature(), and remove the old signature().
