Qt signal slot template class

It saves you to create a slot in your class which simply is emitting a signal. the text in the signal & slot explanatory part below the graph and shortly before the heading Signals is You can connect as many signals as you want to a single slot, and a signal can be connected to as many slots as you need.

There are two drawbacks in this simple implementation: It’s not threadsafe and you cannot disconnect a slot from a signal from within the slot callback. Both problems are easy to solve but would make this example more complex. Using this Signal class other patterns can be implemented easily. Signals and Slots in Depth | C++ GUI Programming with Qt4 ... The signals and slots mechanism is fundamental to Qt programming. It enables the application programmer to bind objects together without the objects knowing anything about each other. We have already connected some signals and slots together, declared our own signals and slots, implemented our own ... Creating Custom Qt Types | Qt Core 5.12.3 Standard types such as QSize, QColor and QString can all be stored in QVariant objects, used as the types of properties in QObject-based classes, and emitted in signal-slot communication. In this document, we take a custom type and describe how to integrate it into Qt's object model so that it can be stored in the same way as standard Qt types. How Qt Signals and Slots Work - Woboq
