Qt execute slot without signal

By author

You cannot use Qt's signal/slot mechanisms without using QObject/Q_OBJECT. You theoretically could create a dummy QObject and compose it into your class. The dummy would then forward the slot calls to your class. You will probably run in to issues with lifetime management, for the reasons that Liz has described in her comment.

Сигнал испускается, когда происходит определенное событие. Виджеты Qt имеют множество предопределенных сигналов, и вы всегда можете создать их подклассы, чтобы добавить свои сигналы. Слот - это функция, вызываемая в ответ на определенный сигнал.

Setting this value only has effect on items that are in the immediate menus of the menubar, not the submenus of those menus. For example, if you have File menu in your menubar and the File menu has a submenu, setting the MenuRole for the actions in that submenu have no effect.

To place an invocation in an event loop, make a queued signal-slot connection. Whenever the signal is emitted, its arguments will be recorded by the event system. The thread that the signal receiver lives in will then run the slot. Alternatively, call QMetaObject::invokeMethod() to achieve the same effect without signals.
