* QObject: add startTimer() overload with std::chronoAnton Kudryavtsev2016-12-231-0/+11
| | | | | | | | | | | | | | | In client code I often see code like: startTimer(1000); //ms Let the code to be self-explaining. So provide overload method that takes std::chrono::milliseconds as arg. QTimer already has std::chrono support, but QObject does not.

* Document Q_ENUM and Q_FLAGOlivier Goffart2015-03-031-9/+8
| | | | | | | | | | | | [ChangeLog][QtCore] Q_ENUMS and Q_FLAGS have been deprecated, and replaced by Q_ENUM and Q_FLAG macros. These two new macros automatically register the enum with the Qt metatype system, allowing automatic conversion to or from string in QVariant, or to show the strings by QDebug operators. They also enable the new QMetaEnum::fromType function.

| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* QObject: allow connecting to functors with a receiver objectDario Freddi2013-09-161-0/+15
| | | | | | | | | | | | | | | | | | | | | | | Up to now, it was only possible to connect to functors in a direct way, without being capable of using Qt::ConnectionType. This patch allows for specifying a receiver for Functors and function pointers, hence making it possible to specify effectively the connection type. To do this properly, it was needed to add an enum in FunctionPointer representing whether the considered function is a member function or not, to reduce ambiguity upon overloaded calls. Moreover, now senders are checked for the existence of a slot obj as well. This way, should the context be freed, the slot obj and the functor contained in it will be freed as well. On a side note, connecting to a static slot (like QCoreApplication::quit) specifying the receiver object is now compiling.

* Optimize code sample of QObject::isSignalConnectedOlivier Goffart2013-02-021-1/+2
| | | | | | | | | | | | | | Since isSignalConnected is meant to be used in performance critical code, and that QMetaMethod::fromSignal is relatively slow, it is better to have it a a static variable in the code sample, as a good recommendation on how to use it. Since QMetaMethod::fromSignal should not change during the life of the program, it should be safe. Also, if different threads run at the same time, both should lead to the same result.

* Add QMetaMethod-based QObject::connect/disconnectNotify() APIKent Hansen2012-05-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This API will fully replace the const char *-based connectNotify() and disconnectNotify() in Qt5; the old functions will be REMOVED before Qt 5.0 final. The new implementation fixes the long-standing issue of connectNotify() not being called when using the (internal) index-based QMetaObject::connect() (e.g., from QML). As with the old API, there are still two "unintuitive" behaviors concerning disconnectNotify(): - disconnectNotify() is not called when the signal is disconnected using the QObject::disconnect(QMetaObject::Connection) overload. - disconnectNotify() is not called when a receiver is destroyed (i.e., when a connection is implicitly removed). The old versions of connectNotify() and disconnectNotify() are kept for now, and they are still called. They will be removed once known existing reimplementations (e.g., QtNetwork, QtDBus) have been ported to the new API.
