When using instances of QML files by directly declaring them, every property creates a binding. This is explained in the above examples. This is how you dynamically create components: var component = Qt.createComponent("Popup.qml"); var popup = component.createObject(parent, {"widt...

Let's pick as an example a function that takes 2 Map and return a Map containing every element in ma and mb: def merge2Maps(ma: Map[String, Int], mb: Map[String, Int]): Map[String, Int] A first attempt could be iterating through the elements of one of the maps using for ((k, v) <- map) and so...

The following is an example for setting and reading cookies using the cookie-parser module: var express = require('express'); var cookieParser = require('cookie-parser'); // module for parsing cookies var app = express(); app.use(cookieParser()); app.get('/setcookie', function(req, res){ ...

In Express, you can define middlewares that can be used for checking requests or setting some headers in response. app.use(function(req, res, next){ }); // signature Example The following code adds user to the request object and pass the control to the next matching route. var express = req...

The XML document, I will be using throughout the examples is - <a> <b>test-value</b> <d>fragment-d</d> <c-root> <d>fragment-d</d> <e>fragment-e</e> </c-root> </a> The following queries ...

xdmp:estimate(cts:search(fn:doc(), cts:element-value-query(xs:QName("d"), "fragment-d"))) xdmp:estimate can not be used on XPaths unlike fn:count is used in previous example xdmp:estimate actually gives the number of matching fragments

The XML document to consider in this example - <a> <b>test-value</b> <d>fragment-d</d> <c-root> <d>fragment-d</d> <e>fragment-e</e> </c-root> </a> A fragment root is declared on <c-r...

Lets start with creating our first app Open visual studio and > create new project Enter Name and Location Enter your developer site url created in previous step and select Provider-hosted Popup will open which will as for login Next step it will as for type of applicatio...

QStack<T> is a template Qt class providing stack. Its analogue in STL is std::stack. It is last in, first out structure (LIFO). QStack<QString> stack; stack.push("First"); stack.push("Second"); stack.push("Third"); while (!stack.isEmpty()) { cout ...

QVector<T> provides dynamic array template class. It provides better performance in most cases than QList<T> so it should be first choice. It can be initialized in various ways: QVector<int> vect; vect << 1 << 2 << 3; QVector<int> v {1, 2, 3, 4}; Th...

void DispatchToMainThread(std::function<void()> callback) { // any thread QTimer* timer = new QTimer(); timer->moveToThread(qApp->thread()); timer->setSingleShot(true); QObject::connect(timer, &QTimer::timeout, [=]() { // main thread ...

Q_OBJECT macro appears in private section of a class. Q_OBJECT requires the class to be subclass of QObject. This macro is necessary for the class to declare its signals/slots and to use Qt meta-object system. If Meta Object Compiler (MOC) finds class with Q_OBJECT, it processes it and generates C+...

Multiplicity in Entity Relationships Multiplicities are of the following types: One-to-one: Each entity instance is related to a single instance of another entity. One-to-many: An entity instance can be related to multiple instances of the other entities. Many-to-one: multiple instances of an ...

Usually you'd want to create a stack of services to form a replicated and orchestrated application. A typical modern web application consists of a database, api, frontend and reverse proxy. Persistence Database needs persistence, so we need some filesystem which is shared across all the nodes in ...

Given a non-empty cv::Mat img of some size, we can fill it to a solid color in several ways: img = cv::Scalar(blueVal,greenVal,redVal); or, the more general, mask supporting, cv::Mat::setTo(): img.setTo(cv::Scalar(blueVal,greenVal,redVal)); If you are using the older OpenCV C API with IplIma...
