SET-1: QML Theory

  QML Applications QML is a declarative language that allows user interfaces to be described in terms of their visual components and how they interact and relate with one another. It is a highly readable language that was designed to enable components to be interconnected in a dynamic manner, and it allows components to be easily reused and customized within a user interface. Using the  QtQuick  module, designers and developers can easily build fluid animated user interfaces in QML, and have the option of connecting these user interfaces to any back-end C++ libraries. What is QML? QML is a user interface specification and programming language. It allows developers and designers alike to create highly performant, fluidly animated and visually appealing applications. QML offers a highly readable, declarative, JSON-like syntax with support for imperative JavaScript expressions combined with dynamic property bindings. The QML language and engine infrastructure is provided by ...

C++11/14 Concepts

  Explicitly Defaulted and Deleted Functions in C++ 11 Last Updated :  08 May, 2018 Defaulted Function What is a Defaulted Function? Explicitly defaulted function declaration is a new form of function declaration that is introduced into the C++11 standard which allows you to append the  ‘=default;’  specifier to the end of a function declaration to declare that function as an explicitly defaulted function. This makes the compiler generate the default implementations for explicitly defaulted functions, which are more efficient than manually programmed function implementations. For example, whenever we declare a parameterized constructor, the compiler won’t create a default constructor. In such a case, we can use the default specifier in order to create a default one. The following code demonstrates how: // C++ code to demonstrate the // use of defaulted functions #include <iostream> using namespace std;     class A { public :      ...
