Qt5 C++ Signal And Slots With Practical Examples #4
 
08:40
In this video iam going to show you how you can create Signal And Slots in Qt5 C++ with Practical Examples, in this we are going to introduce Signal And Slots in Qt5 C++ after that we see some Practical Examples, it will be coding Examples and Graphical Examples What is Signal And Slots in Qt5 C++ Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. In GUI programming, when we change one widget, we often want another widget to be notified. More generally, we want objects of any kind to be able to communicate with one another. For example, if a user clicks a Close button, we probably want the window's close() function to be called. In Qt 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. Qt's widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in.

Daniel Eriksson / Johan Thelin: Getting Qt's signal/slot mechanism in standard C++
 
44:46
Abstract: A fundamental property of the Qt framework is the so called signals and slot mechanism. It is a generic event mechanism which is easy to use. By providing an interface of provided events (signals) and required handlers (slots) where a signal needs to be connected it is easy to connect objects with each other without specifying explicit dependencies. This event mechanism also works between objects in different threads. However, the Qt signal and slot mechanism is dependent on meta information which is generated by the so called MOC, the Meta Object Compiler. For this to work the signals and slots keywords are added to C++. This makes a Qt program that uses signals and slots impossible to compile without the MoC and the Qt super object QObject. So is there anyway to get this signal and slots mechanism using standard C++? We are going to present how Qt and QObject works and describe the implementation of signal and slots mechanism and compare that to two libraries from boos called Signals2 and Synapse that provides the same thing but based on standard C++.

QtDD13 - Olivier Goffart - Signals and Slots in Qt 5
 
55:31
Recorded at the Qt Developer Days in Berlin in 2013. Slides available at https://devdays.kdab.com/?page_id=225 Short Abstract: Signals and Slot is one of the Qt's key concept. Qt 5 introduce a new connection syntax, which allows compile time checking, smart type conversion, connection to lambdas, and more. In this talk, we will compare the old and the new syntax, see how to use it and what is possible, including tips and pitfalls. We will also go a bit under the hood and look a bit of the implementations of signals and slots which should help you to understand them even better. Abstract: One of Qt's main particularity are the signals and slots. They enabled from the beginning making easy user interface and are probably a key to Qt's success. They still play a big role in QML. Qt5 which was just released less than a year ago, introduces a new syntax for connecting your signals and slot. Instead of using the SIGNAL and SLOT macro, you can use pointer to member functions. This has numerous advantages such as compile time checking of the validity of the connection, and automatic conversion of types regardless of typedefs or namespaces, or to be able to connect to lambda expressions. This talk will introduce this new syntax in details, with examples of what you can do and common mistakes to avoid. We will also go over some implementation detail and design decision behind it. It is much easier to understand and use efficiently. Presenter Biography: Olivier Goffart started working with Qt 10 years ago with his involvement in KDE. He was then hired by Trolltech to work on Qt in 2007. He has been working on various areas of Qt including the itemview framework, the widget stylesheets, QtScript, the QObject internals, and the QML debugger for Creator. He is now the co-founder of Woboq, a company based in Berlin focussing on Qt.
