* Split qobject_impl.h into qobjectdefs_impl.hKent Hansen2012-04-251-425/+0
| | | | | | | | | | | | | | | | | | | This is done to make QtPrivate::FunctionPointer available to the QMetaMethod declaration in qmetaobject.h (which already included qobjectdefs.h, since that's where QMetaObject is declared), so that the new template-based QMetaMethod::fromSignal() function may be implemented. The logic for statically generating the array of qMetaTypeId (used by the template-based QObject::connect()) remains in qobject_impl.h, since it's not needed for QMetaMethod::fromSignal(). Moreover, moving that code would introduce a circular dependency, since qmetatype.h as of commit 194674044693d6b101c3dc2f4784718540d343a4 now includes qobjectdefs.h.

* Remove "All rights reserved" line from license headers.Jason McDonald2012-01-301-1/+1
| | | | | | | | | | As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

* Better error reporting in case of connection failure.Olivier Goffart2011-12-201-16/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use Q_STATIC_ASSERT_X give a better error message. If C++11 is used, you get the string in the error. Else, clicking on the QStaticFailure error still shows you the string in the qobject.h source code) And report better failure if the return types do not match. (Without the static assert, you would still have a compilation error, but in an unrelated place, with no reference to the actual connect() call. The error was thrown from the virtual call QSlotObject::call, without saying where it was instantiated) Previously the error was relying on the existence of a type inside CheckCompatibleArguments, but the Q_STATIC_ASSERT requires a bool (hence the introduction of CheckCompatibleArguments::value) There also was a typo in the return value of AreArgumentsCompatible::dummy that made that code not work, and that error not be reported. (Instead, the error was reported when QObjectSlot::call is instantiated) Specialization of AreArgumentsCompatible for the void type have been added because if the return value of a signal or slot is void, the connection should work.

* Fix Qt::QueuedConnection when signal has a return valueOlivier Goffart2011-11-301-2/+4
| | | | | | | | | | For queued connections, the args[0] is set to null as it make no sens to forward the return value to the signal. So we need to check in the operator, that the pointer is not null.

* New QObject connection syntaxOlivier Goffart2011-11-251-0/+354
In addition to the old connection syntax, you can now connect using function pointers. connect(sender, &Sender::valueChanged, receiver, &Receiver::updateValue ); You can connect also to functor or C++11 lambdas The connections are now type safe (no more problems with namespaces or typedefs). Implicit type conversion is also supported. The new syntax forces us to change the meaning of signal form protected to public, in order to be able to access the signal's address everywhere The way it works is by introducing new overload of QObject::connect that take function pointer as parametter. Those new overload are template function, that are implemented inline. The actual implementation is in QObject::connectImpl which take a QObject::QSlotObject* as parametter for the slot. That slot object contains a virtual function which call the slot which has to be implemented in the header as it depends on the template parametter. So the internals of QObjectPrivate::Connection will store this QObjectSlot* in order to be able to make the call.

Qt::UniqueConnection is not supported yet in the new overload. Change-Id: I67d08436b0720e7f2992be9f7e34770960fa58fa Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
