Qt signals
Qt language supports the use of signals and slots for communication between objects. Using them can be beneficial when using observer pattern because they eliminate boilerplate code. This article will show you how to use slots and signals to implement observer pattern in Qt. But before you dive into the subject, you should know what they are.
Signals are used to inform a possible observer that something has happened. They can be sent using emit keyword. Slots are functions that execute when signals are emitted.
Qt slots
Signals and slots are constructs in the Qt language that help to communicate between objects. They make it easy to implement the observer pattern without writing boilerplate code. Using signals and slots is particularly helpful when creating complex objects such as windows. Here’s a quick overview of how to use these constructs to communicate with each other.
The first thing to do is declare slots and signals in your project. You must declare them in the header file of your application. Then, create a slot and signal and attach them to each other. Make sure to add and remove slots.
Qt function pointers
The signal slot is a very famous Qt feature. It allows you to send signals from one object to another. However, it has certain limitations. First, a signal must be in the same class as the object that sends it. If it’s in the wrong class, the signal will be ignored.
QSlotObjectBase implements this functionality in a non-polymorphic way, using the m_impl variable to emulate virtual functions. This means that the function pointer m_impl is a normal function pointer and “re-implements” set the value of m_impl in the constructor.
