since most of the content is from documentation or forum threads, it can be regards as same license as QT documentation. Most of text are copied from internetC++11 is still lacking the type system information, boost seems improve it on this topics. The metadata of QObject is the basis of QT lib. Boost Signals — сигналы и слоты для C++ Сегодня я расскажу про библиотеку Boost Signals — про сигналы, слоты, соединения, и как их использовать. Сигнал — это тип данных, который может хранить в себе несколько функций обратного вызова, и вызывать их. Слот — это, соответственно, и есть подсоединяемые к... C++ Qt с использованием boost:: shared_ptr в сигнале/… Похоже, что ссылочный тип const в сигнале/слоте будет просто упорядочен как нормальный shared_ptr, что здесь вполне нормально.У меня такое ощущение, что простая shared_ptr версия - это все, что необходимо, и это пространство имен boost, которое мешает сигналам. Qt - Сигналы и слоты — Кафедра ИУ5 МГТУ им.… Сигналы и слоты - это то, как в Qt взаимодействуют между собой объекты разных классов. Связь между объектами устанавливается следующим образом: у одного объекта должен быть сигнал, а у второго - слот.

Всем доброго дня. Реквестирую истории успеха/неуспеха использования сигналов/слотов из состава boost. Интересует в первую очередь сравнение с кутишными сигналами/слотами.

From Qt signal to Boost signal The Qt signal syntax is easier to read and write. When using only Qt, adding the Boost signals libraries increase compile time.The program implements two classes: an emitter and a receiver. After connecting the signals and slots, the emitter emits a signal, received by the receiver. Boost Signals — сигналы и слоты для C++ / Хабр Сегодня я расскажу про библиотеку Boost Signals — про сигналы, слоты, соединения, и как их использовать.Слот — это, соответственно, и есть подсоединяемые к сигналу функции. Как уже было сказано, к одному сигналу можно подключить несколько функции, и при вызове...
If you've ever used Qt to build a GUI, you're probably familiar with their signal/slots implementation. For me, it was my first encounter with the idiom and I really liked it. The design made me feel like I could have different elements interact with eachother without them even being aware of ...
Signals & Slots | Qt 4.8 Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.

Boost Thread Qt Application - Qt Wiki In that method (I'm in QApplication context, i.e. "Thread B"), I can create my widget and show it in the end, I just signal (using a QWaitCondition) that my widget is shown, so "Thread C" can return. The final result is that all my Qt classes have been created in the QApplication thread context, just as a normal Qt application. std::signal - cppreference.com Sets the handler for signal sig. The signal handler can be set so that default handling will occur, signal is ignored, or a user-defined function is called. When signal handler is set to a function and a signal occurs, it is implementation defined whether std:: signal (sig, SIG_DFL) will be executed immediately before the start of signal ...
