One of the very basic animations that you could come across is the NumberAnimation. This animation works by changing the numeric value of a property of an item from an initial state to a final state. Consider the following complete example: import QtQuick 2.7 import QtQuick.Controls 2.0 ...

The empty-cells property determines if cells with no content should be displayed or not. This has no effect unless border-collapse is set to separate. Below an example with two tables with different values set to the empty-cells property: The table on the left has empty-cells: show while the one...
$string = "0| PHP 1| CSS 2| HTML 3| AJAX 4| JSON"; //[0-9]: Any single character in the range 0 to 9 // + : One or more of 0 to 9 $array = preg_split("/[0-9]+\|/", $string, -1, PREG_SPLIT_NO_EMPTY); //Or // [] : Character class // \d : Any digit // + : One or more ...
In some cases, you might not want to use the default maps, Apple provides. You can add an overlay to your mapView that contains custom tiles for example from OpenStreetMap. Let's assume, self.mapView is your MKMapView that you have already added to your ViewController. At first, your ViewControll...
You can use route parameters to get the part of the URI segment. You can define a optional or required route parameter/s while creating a route. Optional parameters have a ? appended at the end of the parameter name. This name is enclosed in a curly braces {} Optional Parameter Route::get('profi...

ViewData is the mechanism for a controller to provide data to the view it presents, without using a ViewModel. Specifically, ViewData is a dictionary which is available both in MVC action methods and views. You may use ViewData to transfer some data from your action method to the view returned by th...
Initialize the UITapGestureRecognizer with a target, self in this case, and an action which is a method that has a single parameter: a UITapGestureRecognizer. After initialization, add it to the view that it should recognize taps in. Swift override func viewDidLoad() { super.viewDidLoad() ...
There are a number of collection types in Python. While types such as int and str hold a single value, collection types hold multiple values. Lists The list type is probably the most commonly used collection type in Python. Despite its name, a list is more like an array in other languages, mostl...
For instance, a computation involving commands to read and write from the prompt: First we describe the "commands" of our computation as a Functor data type {-# LANGUAGE DeriveFunctor #-} data TeletypeF next = PrintLine String next | ReadLine (String -> next) derivin...
There are two parts of a class: the interface and the implementation. The interface is the exposed functionality of the class. Its public methods and variables are part of the interface. The implementation is the internal workings of a class. Other classes shouldn't need to know about the implemen...
Encapsulation allows you to make internal changes to a class without affecting any code that calls the class. This reduces coupling, or how much any given class relies on the implementation of another class. For example, let's change the implementation of the Angle class from the previous example: ...
When implementing more than one interface that have methods of the same name that include default implementations, it is ambiguous to the compiler which implementation should be used. In the case of a conflict, the developer must override the conflicting method and provide a custom implementation. ...
x = np.arange(4) x #Out:array([0, 1, 2, 3]) scalar addition is element wise x+10 #Out: array([10, 11, 12, 13]) scalar multiplication is element wise x*2 #Out: array([0, 2, 4, 6]) array addition is element wise x+x #Out: array([0, 2, 4, 6]) array multiplication is element wise x...
If an object is defined with static, thread, or automatic storage duration, and it has a character type, either: char, unsigned char, or signed char, it may not be accessed by a non-character type. In the below example a char array is reinterpreted as the type int, and the behavior is undefined on e...
Installing Jasmine standalone Download the latest Jasmine release from the Jasmine release page: Running Jasmine locally Run Jasmine in the browser by downloading the zip file, extracting it, the referencing the files as follows: <link rel="shortcut icon" type="image/png&qu...
jQuery offers a variety of methods that can be used for DOM manipulation. The first is the .empty() method. Imagine the following markup: <div id="content"> <div>Some text</div> </div> By calling $('#content').empty();, the inner div would be removed. This...
A query engine is required in order to execute SPARQL queries over a dataset. Query engines may be embedded in applications, or accessed remotely. Remote access may be through a vendor-specific API, or through the SPARQL protocol if an implementation supports it. This documentation will not cover ho...
