Qt signal slot naming convention

Если пользовательский интерфейс Qt имеет несколько однотипных элементов управления, сигналы от них удобно обрабатывать при помощи signal mapping. Например, есть виджет с 8 checkbox’ами, при помощи которых можно задать битовую маску.

Как работают сигналы и слоты в Qt | Блог разработчиков… Сигналы и слоты, а также система свойств Qt, базируются на вероятностях самоанализа объектов во время выполнения программы. Самоанализ обозначает способность перечислить способы и свойства объекта и иметь всю информацию про них, в частности, о типах их доводов. Qt Сигналы и слоты, что и как? Главной особенностью библиотеки Qt является технология сигналов и слотов ( Signals and slots). Не могу вам сказать что она чем-то значительно лучше других подходов, но мне эта штука нравится :). В чем же суть.

Naming convention of server signals expected in response to the server slot call. We assume that real server doesn’t have any real signals that it connects to client slots, however, as a response to call of any slot, server can send reply to the client. Client, on the other hand, can connect its slot to the response on calling the server slot. GitHub - DaedalicEntertainment/qt-coding-conventions: High ...

In Qt based projects, it doesn’t make sense to reinvent a wheel again because you can use style which is already used in Qt development. When using one coding convention through any software project, it makes developer collaboration smoother because it’s easier to read code which others have written. 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.
