Implementing Model/View/Controller - Qt Qt 4 uses the MVC pattern for its item view classes (QListView, QTable, etc.). But MVC is more than just a pattern for item views: it can be used generally as a means of keeping different widgets synchronized. In this article, we show how to apply it, taking full advantage of Qt's signal--slot mechanism. 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.

Signals and slots - Wikipedia Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots. This is similar to C/C++ function pointers, but Qt's unique patterns - Stack Overflow Qt providing special classes for using design patterns like the Qt Quick module, Signal Slots.. The second part is the structure of some classes for example: QWidget QWidget inherits from QObject which implements the composite pattern. Signal/Slot design pattern — signalslot 0.1.1 documentation Signal/Slot is a widely used pattern, many frameworks have it built-in including Django, Qt and probably many others. If you have a standalone project then you probably don’t want to add a big dependency like PyQt or Django just for a Signal/Slot framework. Meeting 13: Qt Signals and Slots - filebox.ece.vt.edu
