The SpriteArranger sample application builds upon the Geometric Shapes sample application described separately in Learning ActionScript 3.0. The SpriteArranger sample application illustrates a number of concepts for dealing with display objects: • Extending display object classes • Adding objects to the display list • Layering display objects and working with display object containers • Responding to display object events • Using properties and methods of display objects To get the application files for this sample, see. The SpriteArranger application files can be found in the folder Examples/SpriteArranger. The application consists of the following files. File Description SpriteArranger.mxml or SpriteArranger.fla The main application file in Flash (FLA) or Flex (MXML). Com/example/programmingas3/SpriteArranger/CircleSprite.as A class defining a type of Sprite object that renders a circle on-screen. Com/example/programmingas3/SpriteArranger/DrawingCanvas.as A class defining the canvas, which is a display object container that contains GeometricSprite objects. Com/example/programmingas3/SpriteArranger/SquareSprite.as A class defining a type of Sprite object that renders a square on-screen. Com/example/programmingas3/SpriteArranger/TriangleSprite.as A class defining a type of Sprite object that renders a triangle on-screen. Com/example/programmingas3/SpriteArranger/GeometricSprite.as A class that extends the Sprite object, used to define an on-screen shape.

Momentum Textiles, commercial upholstery for the office, healthcare, and hospitality markets. The CircleSprite, SquareSprite, and TriangleSprite each extend this class. Com/example/programmingas3/geometricshapes/IGeometricShape.as The base interface defining methods to be implemented by all geometric shape classes. Com/example/programmingas3/geometricshapes/IPolygon.as An interface defining methods to be implemented by geometric shape classes that have multiple sides.

Com/example/programmingas3/geometricshapes/Circle.as A type of geometric shape that defines a circle. Com/example/programmingas3/geometricshapes/EquilateralTriangle.as A subclass of RegularPolygon that defines a triangle with all sides the same length. Com/example/programmingas3/geometricshapes/Square.as A subclass of RegularPolygon defining a rectangle with all four sides the same length. Com/example/programmingas3/geometricshapes/GeometricShapeFactory.as A class containing a “factory method” for creating shapes given a shape type and size. The DrawingCanvas class In Flex, all child display objects added to a Container object must be of a class that descends from the mx.core.UIComponent class. This application adds an instance of the DrawingCanvas class as a child of an mx.containers.VBox object, as defined in MXML code in the SpriteArranger.mxml file. This inheritance is defined in the DrawingCanvas class declaration, as follows: public class DrawingCanvas extends UIComponent The UIComponent class inherits from the DisplayObject, DisplayObjectContainer, and Sprite classes, and the code in the DrawingCanvas class uses methods and properties of those classes. The DrawingCanvas class extends the Sprite class, and this inheritance is defined in the DrawingCanvas class declaration, as follows: public class DrawingCanvas extends Sprite The Sprite class is a subclass of the DisplayObjectContainer and DisplayObject classes, and the DrawingCanvas class uses methods and properties of those classes. The DrawingCanvas() constructor method sets up a Rectangle object, bounds, which is property that is later used in drawing the outline of the canvas. It then calls the initCanvas() method, as follows: this.bounds = new Rectangle(0, 0, w, h); initCanvas(fillColor, lineColor); AS the following example shows, the initCanvas() method defines various properties of the DrawingCanvas object, which were passed as arguments to the constructor function: this.lineColor = lineColor; this.fillColor = fillColor; this.width = 500; this.height = 200; The initCanvas() method then calls the drawBounds() method, which draws the canvas using the DrawingCanvas class’s graphics property. The graphics property is inherited from the Shape class. This.graphics.clear(); this.graphics.lineStyle(1.0, this.lineColor, 1.0); this.graphics.beginFill(this.fillColor, 1.0); this.graphics.drawRect(bounds.left - 1, bounds.top - 1, bounds.width + 2, bounds.height + 2); this.graphics.endFill(); The following additional methods of the DrawingCanvas class are invoked based on user interactions with the application: • The addShape() and describeChildren() methods, which are described in • The moveToBack(), moveDown(), moveToFront(), and moveUp() methods, which are described in • The onMouseUp() method, which is described in. Adobe Flex Sample Application Code Couleur 2017The GeometricSprite class and its subclasses Each display object the user can add to the canvas is an instance of one of the following subclasses of the GeometricSprite class: • CircleSprite • SquareSprite • TriangleSprite The GeometricSprite class extends the flash.display.Sprite class: public class GeometricSprite extends Sprite The GeometricSprite class includes a number of properties common to all GeometricSprite objects. These are set in the constructor function based on parameters passed to the function. For example: this.size = size; this.lineColor = lColor; this.fillColor = fColor; The geometricShape property of the GeometricSprite class defines an IGeometricShape interface, which defines the mathematical properties, but not the visual properties, of the shape. The classes that implement the IGeometricShape interface are defined in the GeometricShapes sample application described in Learning ActionScript 3.0. The GeometricSprite class defines the drawShape() method, which is further refined in the override definitions in each subclass of GeometricSprite. For more information, see the “Adding display objects to the canvas” section, which follows. The GeometricSprite class also provides the following methods: • The onMouseDown() and onMouseUp() methods, which are described in • The showSelected() and hideSelected() methods, which are described in. When the user clicks on a GeometricSprite instance, the application calls the onMouseDown() event handler. As the following shows, this event handler is set to listen for mouse down events in the constructor function of the GeometricSprite class: this.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown); The onMouseDown() method then calls the showSelected() method of the GeometricSprite object. Creating Flex project in Flash Builder Creating A Flex project in Flash Builder is not so difficult. The IDE of flash builder is same as Eclipse. Flash builder is built on top of eclipse – the development environment which is strongly associated with java development. Although flash builder, certainly, is not necessary for creating flex applications and as such, provides a lot of features to help you design and develop applications more effectively. For creating flex project in flash builder you can use flash builder either as a standalone application or as a plug in to an installation of Eclipse. The first thing to do as a flex developer is to create a new Flex project. Now we can see how we can create Flex project in Flash builder. For creating a flex project in flash builder, first open the flash builder then go to Files -> New -> Linear models with r second edition far away pdf compressor online. Flex Project Creating Flex project in Flash Builder Then we have to give one name for our project. Here I am giving name as Sample. Then we have to select the type of project either web or desktop. If you are using web then it will use flash player for running your application otherwise if you are using desktop then it will use AIR ( Adobe Integrated Run time ) for running the application. And finally, select the flex SDK version. The default version is recommended. Creating Flex project in Flash Builder Next we have to select the type of server, if your application is connecting to a server, and if so, server type is required. If your application is not using any server then just select None/Other. And finally set the output folder. By default, the folder is bin-debug if you want to change then you can. Creating Flex project in Flash Builder Next we have to set the path for our new project. Adobe Flex Sample Application Code CouleursHere we are setting the source folder in example src, and the main application file in example Sample.mxml. If you want to add any SWC files to the project, click the library path tab there you can add swc files by clicking on the add swc button. Then you can click on the finish button. Now your project is configured and ready to begin development! An Adobe SWC file is a package of precompiled Flash symbols and ActionScript code that allows a Flash or Flex developer to distribute classes and assets, or to avoid recompiling symbols and code that will not change. SWC files can be generated by the Flash authoring tool, and by Flex. They are sometimes referred to as class libraries and cannot be directly executed by the Flash player. Android Sample Application CodeCreating Flex project in Flash Builder Now we got the code window. Creating Flex project in Flash Builder Understanding the namespace when Creating Flex project in Flash Builder For Creating Flex project in Flash Builder you should know what is a namespace in Flex. After opening the Flex IDE you can find some lines of code. These codes are used for specifying the namespace. Flex 4 provides three packages of components, and each is identified by a unique namespace. The three Flex 4 namespaces are Spark ( s:), Halo ( mx:), and the Language ( fx:) namespace. In flex 3 the spark namespace is not available.
