USING FLASH BUILDER

About Flash Builder

Flash Builder versions

Flash Builder is available in two versions: Standard and Premium.

Flash Builder Standard Flash Builder Standard provides a full-featured IDE that allows you to create applications

using the Flex framework and Flash API. Flash Builder Standard also includes MXML, ActionScript, and CSS editors, as well as debugging tools. Flash Builder Standard provides a library of interactive charts and graphs that enable you to create rich data dashboards, interactive data analysis, and data visualization components.

Flash Builder Premium In addition to the Standard version features, Flash Builder Premium includes memory and

performance profiling and automated testing tools. Use the Network Monitor to view the data that flows between a client application and a data service. The FlexUnit test environment allows you to generate and edit repeatable tests. The repeatable tests can be run from scripts or directly within Flash Builder or outside the Flash Builder environment. The Command Line Build feature allows you to synchronize a developer’s individual build settings with a nightly build.

Flash Builder for PHP Standard Flash Builder for PHP Standard provides a full-featured PHP IDE that includes Flash

Builder Standard integrated with Zend Studio 8. You can build mobile, web, and desktop applications using PHP, Flex, and ActionScript.

Flash Builder for PHP Premium In addition to Standard version capabilities, Flash® Builder™ for PHP Premium

includes professional testing tools, including profilers, network monitoring, an automated testing framework, integration with FlexUnit testing, and Command Line Build support.

For more information on Flash Builder for PHP, see Introducing Flash Builder for PHP.

Flash Builder configurations

Flash Builder provides a single downloadable installer with the following two configuration options:

Stand-alone configuration Installs Flash Builder as a stand-alone integrated development environment (IDE). The

stand-alone configuration is created specifically for developing applications that use the Flex framework and ActionScript 3.0. This configuration is ideal for new users and users who intend to develop applications using only the Flex framework and ActionScript 3.0.

Plug-in configuration Configures Flash Builder to run as a plug-in within an existing Eclipse™ installation.

To run the plug-in configuration, you must have Eclipse 3.7 or Eclipse 4.2 installed as follows:

• On Windows, to run Flash Builder 32-bit plug-in configuration, install Eclipse 3.7/4.2 32-bit

• On Windows, to run Flash Builder 64-bit plug-in configuration, install Eclipse 3.7/4.2 64-bit

• On Mac, to run Flash Builder 64-bit configuration, install Eclipse 3.7/4.2 Cocoa 64-bit

The Flash Builder plug-in and stand-alone configurations provide the same functionality. If you aren't sure which configuration to use, follow these guidelines:

• If you already have Eclipse 3.7 or 4.2 installed, use the plug-in configuration to add Flash Builder features to your

existing copy of Eclipse.

• If you don't have Eclipse installed and your primary focus is on developing Flex and ActionScript applications, use

the Flash Builder stand-alone configuration. This configuration also allows you to install other Eclipse plug-ins to expand the scope of your development work in the future.

For detailed information about installing Flash Builder, see the Flash Builder 4.7 release notes.

Chapter 2: Getting Started With Flash Builder

Flash Builder is an integrated development environment (IDE) for developing applications using the Flex framework and ActionScript 3.0. You can develop applications for deployment on Adobe Flash Player, desktop applications for deployment on Adobe AIR, and mobile applications for deployment on various mobile devices.

Note: The information required to use Flash Builder is contained in the Flash Builder documentation. If you are using other Eclipse plug-ins (such as CVS or Java) with Flash Builder, or you want to extend the Flash Builder plug-ins, see

Adobe Flash Builder Extensibility Reference.

The Flash Builder development environments consists of the following components:

Workbench The term workbench refers to the Flash Builder development environment that contains all the tools to

develop applications. The workbench contains three primary elements: perspectives, editors, and views. You use all three in various combinations at various points in the application development process.

See “Customize the workbench” on page 232.

Note: For more information about some of the Eclipse workbench features, see the Eclipse Workbench User’s Guide at

http://help.eclipse.org/help31/index.jsp.

Perspective A perspective is a group of views and editors in the workbench. Flash Builder contains two perspectives:

The Flash Development perspective for developing applications, and the Flash Debug perspective for debugging applications. Flash Builder Premium also contains the Flash Profiling perspective.

If you use the Flash Builder plug-in configuration (see “Flash Builder configurations” on page 3), your workbench can contain additional perspectives such as a Java perspective that contains editors and views used to develop Java applications.

See “Flash Builder perspectives and views” on page 5.

Editor An editor lets you edit various file types. The editors available to you depend on the number and type of Eclipse

plug-ins installed. Flash Builder contains editors for writing MXML, ActionScript 3.0, and Cascading Style Sheets (CSS) code.

See “Flash Builder editors” on page 11 and “Code Development Tools in Flash Builder” on page 14.

Views A view typically supports an editor. For example, when editing an ActionScript or MXML file, the supported

views are displayed.

See “Work with views” on page 10.

Note: The term “view” is synonymous with the term “panel” as it is used in earlier versions of Flash Builder, Adobe Dreamweaver®, and other Adobe development tools.

Workspace Not to be confused with workbench, a workspace is a defined area of the file system that contains the

resources (files and folders) that make up your application projects. You can work with only one workspace at a time; however, you can select a different workspace each time you start Flash Builder.

See “Move a project from one workspace to another” on page 73 and “Switch the workspace” on page 74.

Resource The term resource is used generically to refer to the files and folders within the projects in a workspace.

See “Project resources” on page 63.

Getting Started With Flash Builder

Project All of the resources that make up your applications are contained within projects. You cannot build an

application in Flash Builder without first creating a project. Flash Builder supports various types of projects, depending on the type of application you are building.

See “Types of projects” on page 55 and “Using Projects in Flash Builder” on page 55.

Launch configuration A launch configuration is created for each of your projects, and it defines project settings that

are used when running and debugging your applications. For example, the names and locations of the compiled application SWF files are contained in the launch configuration, and you can modify these settings.

See “Manage launch configurations” on page 96.

Flash Builder perspectives and views

To support a particular task or group of tasks, editors and supporting views are combined into a perspective. When you open a file that is associated with a particular perspective, Flash Builder automatically opens that perspective.

The stand-alone configuration of Flash Builder contains three perspectives:

• Flash Development

See “The Flash Development perspective” on page 5.

• Flash Debugging

See “The Flash Debug perspective” on page 110.

• Flash Profiling

See “The Flash Profiling perspective and profiler views” on page 122.

Note: The Flash Profiling perspective is available with Flash Builder Premium.

The Flash Development perspective

The Flash Development perspective includes the editors and views you require to create applications for the Flex framework. When you create a project, Flash Builder switches into the Development perspective so you can begin developing your application.

The focal point of the perspective (and the workbench generally) is the editor area. The editor area contains all of the currently open documents in a multitab interface.

When you create a Flex project, the main MXML application file is opened in the editor area. You can then open and switch between any of the MXML, ActionScript, and CSS documents you are working in. For more information, see “Flash Builder editors” on page 11.

The Development perspective contains the editors and the following supporting views:

Package Explorer view

The Package Explorer view contains all of the projects and resources in the workspace and is therefore an essential element of the Flash Builder workbench. It is always displayed in the Development and Debug perspectives.

When you work in the Package Explorer, you can select a resource and view its properties.

1 In the Package Explorer, select a resource.

2 Select File > Properties.

For more information about the Package Explorer and working with projects, see “Manage projects” on page 71.

Outline view

The Outline view presents a hierarchical view of the code structure of the selected MXML or ActionScript document so that you can inspect and navigate the sections or lines of code in the document. The Outline view also displays syntax error alerts that the compiler generates. This view is also available when you use the ActionScript editor.

For more information about using the Outline view in Source mode, see “Use the Outline view” on page 27.

Problems view

As you enter code, the Flash Builder compiler detects syntax and other compilation errors, and these errors are displayed in the Problems view. The Package Explorer marks nodes that contain errors.

When you debug your applications, errors, warnings, and other information are displayed in the Problems view. Each error or warning contains a message, the file and folder in which it is located, and its line number in the file. Problems remain in the Problems view until you correct them or they are otherwise resolved.

Note: You can also optionally add the Tasks and Bookmarks views. These views provide additional shortcuts for managing and navigating your code. For more information about these views, see

“Use markers” on page 32. For an

introduction to the optional views that are available in Flash Builder, see “Display other workbench views” on page 232.

ASDoc view

As you enter code, or hover over code elements, Flash Builder displays ASDoc content relevant to the code. Flash Builder also displays the ASDoc content for the selected code in the ASDoc view.

For more information, see “Display ActionScript reference summary” on page 17.

Network Monitor view

The Network Monitor allows you to examine the data that flows between an application and the data service or services. the Network Monitor is available with Flash Builder Premium.

For more information, see “Monitor applications that access data services” on page 178.

Work with perspectives

Open and switch perspectives

Perspectives change automatically to support the task at hand. For example, when you create a Flex project, the workbench switches to the Development perspective. When you start a debugging session, the Flash Debug perspective is displayed when the first breakpoint is encountered.

You can also manually switch perspectives yourself by selecting Window > Open Perspective. Or, you can use the perspective bar, which is located in the main workbench toolbar.

When the perspective opens, its title changes to display the name of the perspective you selected. An icon appears next to the title, allowing you to quickly switch back and forth between perspectives in the same window. By default, perspectives open in the same window.

If you use the plug-in configuration of Flash Builder and have other Eclipse plug-ins installed, you can have additional perspectives. While predefined perspectives are delivered with each Eclipse plug-in, you can customize them or create your own. To see a complete list of perspectives, select Window

> Open Perspective > Other.

2 (Optional) Save your changes by selecting Window > Save Perspective As.

Rearrange tabbed views

In addition to docking views at different locations in the workbench, you can rearrange the views in a tabbed group of views.

❖ Click the tab of the view to move, drag the view to the desired location, and release the mouse button. A stack

symbol appears as you drag the view across other view tabs.

Switch between views

There are several ways to switch to a different view:

• Click the tab of a different view.

• Select a view from the Flash builder Window menu.

• Use a keyboard shortcut

Use Control+F7 on Windows, Command+F7 on Macintosh. Press F7 to select a view.

For a list of all keyboard shortcuts, go to Help > Key Assist

Create and work with fast views

Fast views are hidden views that you can quickly open and close. They work like other views, but do not take up space in the workbench while you work.

Whenever you click the fast view icon in the shortcut bar, the view opens. Whenever you click anywhere outside the fast view (or click Minimize in the fast view toolbar), the view becomes hidden again.

Note: If you convert the Package Explorer view to a fast view, and then open a file from the Package Explorer fast view, the fast view automatically is hidden to allow you to work with that file.

To create a fast view, do the following:

❖ Drag the view you want to turn into a fast view to the shortcut bar located in the lower-left corner of the workbench

window.

The icon for the view that you dragged appears on the shortcut bar. You can open the view by clicking its icon on the shortcut bar. As soon as you click outside the view, the view is hidden again.

Filter the Tasks and Problems views

You can filter the tasks or problems that are displayed in the Tasks or Problems views. For example, to see only problems that the workbench has logged, or tasks that you logged as reminders to yourself, filter items according to which resource or group of resources they are associated with. You can filter by text string in the Description field, by problem severity, by task priority, or by task status.

1 In Tasks or Problems view taskbar, click Filter.

2 Complete the Filters dialog box and click OK.

For more information about views, see “Work with views” on page 10.

Flash Builder editors

When you develop applications in Flash Builder, you use the MXML, ActionScript 3.0, and CSS editors.

Editors are associated with resource types, and as you open resources in the workbench, the appropriate editor is opened. Each editor provides the functionality required to author the given resource type.

MXML editor You use the MXML editor to edit MXML code and to embed ActionScript and CSS code in

<fx:Script> and <fx:Style> tags.

ActionScript editor You use the ActionScript editor to edit ActionScript class and interface files. You can embed

ActionScript functions into an MXML file by using the

<fx:Script> tag. However, it is a common practice to define

classes in separate ActionScript files and then import the classes into MXML files. Using this method, you can define most of your applications in ActionScript.

CSS editor You use the CSS editor to display and edit Cascading Style Sheets. You can then apply styles to the visual

elements of your applications. For more information, see Styles and themes.

Using the MXML editor

When using the MXML editor, Content Assist helps you add standard Flex containers and controls to your user interface.

The following example shows how to use Content Assist to insert an <s:VGroup> container into an <s:HGroup> container. Because HGroup is a Spark component, Content Assist recommends a VGroup container, and not

<mx:VBox>.

1 Open an MXML file in the MXML editor.

The MXML file can be the main application file (a file with an Application container) or a custom MXML component file.

2 Place the insertion point in the parent container tag.

Last updated 12/3/2012

USING FLASH BUILDER

Getting Started With Flash Builder

For example, to insert a VGroup container inside an HGroup parent container, place the insertion point after the opening

<s:HGroup> insertion point here </s:HGroup>

3 Type the component tag.

<s:HGroup> tag:

As you type the tag, Content Assist appears suggesting possible entries. Recommended components are listed in the normal black type color. Components that are not recommended appear gray.

In this example, VGroup is recommended and VBox is not recommended.

4 If necessary, use the arrow keys to select your tag from the menu, then press Enter.

In addition to the standard components, Content Assist lists custom components you defined in separate MXML and ActionScript files and saved in the current project or in the source path of the current project.

Content Assist can also suggest properties, events, effects, and styles. Press Control+Space to cycle through the recommendations in Content Assist.

You can change the type and order of recommendations for Content Assist. From the Preferences dialog, select Flash Builder

> Editors > MXML Code > Advanced.

Associate editors with file types

You can associate editors with various file types in the workbench.

1 Select Window > Preferences.

2 Click the plus button to expand the General category.

3 Click the plus button to expand the Editors category, and then select File Associations.

4 Select a file type from the File Types list.

To add a file type to the list, click Add, enter the new file type in the New File Type dialog box, and then click OK.

6 Click OK.

You can override the default editor preferences from the context menu for any resource in one of the navigation views. Select Open With from the context menu.

Edit files outside the workbench

You can edit an MXML or ActionScript file in an external editor and then use it in Flash Builder. The workbench performs any necessary build or update operations to process the changes that you made to the file outside the workbench.

Refresh an MXML or ActionScript file edited outside the workbench

1 Edit the MXML or ActionScript file in the external editor of your choice.

2 Save and close the file.

3 Start Flash Builder.

4 From one of the navigation views in the workbench, select Refresh from the context menu.

If you work with external editors regularly, you can enable auto-refresh. To do so, select Window > Preferences,

expand the General category, select Workspace, and check Refresh Automatically. When you enable this option, the workbench records any external changes to the file. The speed with which the auto-refresh happens depends on your platform.

Tiling editors

The workbench lets you open multiple files in multiple editors. But unlike views, editors cannot be dragged outside the workbench to create new windows. You can, however, tile editors in the editor area, so that you can view source files side by side.

1 Open two or more files in the editor area.

2 Select one of the editor tabs.

3 Drag the editor over the left, right, upper, or lower border of the editor area.

The pointer changes to a drop cursor, indicating where the editor appears when you release the mouse button.

4 (Optional) Drag the borders of the editor area of each editor to resize the editors as desired.

Maximize a view or editor

There are several ways you can maximize (restore) a view or editor so that it fills the workbench window.

• From the context menu on the view or editor’s title bar, select Maximize (Restore).

• Double-click the tab of a view.

• From the Flash Builder menu, select Window > Maximize/Restore.

• Click the Maximize/Restore icons in the upper-right corner of the view or editor.

Chapter 3: Code Development Tools in Flash Builder

You edit MXML, ActionScript, and CSS code in Adobe® Flash® Builder™ with separate editors. The Flash Builder workbench is both project- and document-centric. The appropriate editor opens automatically because the editors are associated with resource types. The Flash Builder editors share capabilities, including code hinting, navigation, formatting, refactoring, and other productivity-enhancing features.

Content Assist, Quick Assist, and Quick Fix

Content Assist

As you enter MXML, ActionScript, and CSS code, hints and ASDoc reference documentation displays to help you complete your code. This feature is called Content Assist.

In the MXML editor, if you type within an MXML component, you are prompted with a list of all properties of that component. The following example shows code hints for properties of an MXML component:

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

Selecting and entering properties displays possible property values (if predefined values exist). The following example shows code hints for property values:

Content Assist works similarly for the ActionScript editor and CSS editor.

Content Assist in the MXML editor

In the MXML editor, code hints appear automatically as you enter your code. The following example shows the code hints that are displayed when you add a tag to a Panel tag. It also shows the ASDoc reference documentation. Click inside the ASDoc content, or press F2 to display the content in a separate, scrollable window. Click outside the ASDoc window to close it.

Content Assist categorizes code hints by type, showing you both visual and nonvisual MXML components, properties, events, and styles.

By default, Content Assist only displays code hints for recommended types. Recommended types are those components available in the declared namespace or are otherwise available, depending on the enclosing tags. The components that are available to you in an application depend on the namespace declaration of the application and also the tags enclosing the insertion point in the editor.

For example, in some contexts only Spark components are allowed. In other contexts, both Spark and Halo components are allowed. Content Assist filters the code hints, depending on the context.

Press Control+Space multiple times to cycle through filters for displayed code hints, as listed below:

• Initial display: Recommended types

• All components

• Properties

• Events

Assign to Variable

When you evaluate an ActionScript expression, if the expression returns a value, you can use Quick Assist to create a variable for that expression. Quick Assist is not available for methods that do not have a return type or if the return

void.

type is

The name of the variable that is created is derived from the name of the function or identifier in the expression. If the derived name exists, then the name is incremented.

For example, if you have the following code:

var i:int; i;

Place your cursor after "i", and invoke Quick Assist. Then, select Assign Statement To A New Local Variable. A variable

"i2" is created. Because the variable i is already present, the new variable name is incremented to "i2" as

follows:

Context Example

Literal Expression Quick Assist supports a wide range of simple and complex expressions.

For example, if you have an expression as follows:

100+150

Place your cursor anywhere within the expression, and press Control+1, then you get code like the following:

var number2:Number = 110 + 500;

Method Call If you have the following code within a method:

var ac:ArrayCollection = new ArrayCollection(); ac.createCursor();

Place your cursor within ac.createCursor(); and press Control+1. Then, select the option to assign the statement to a new local variable. The local variable is created as follows:

var createCursor:IViewCursor = ac.createCursor();

Property Access If you have the following code within a property:

var ac:ArrayCollection = new ArrayCollection(); ac.source;

Place your cursor anywhere within ac.source, and press Control +1. Then, select the option to assign the statement to a new local variable. The local variable is created as follows:

var source:Array = ac.source;

Convert Local Variable to Field

When you have local variables inside a function, Quick Assist lets you create a field in the class.

For example, if you have a variable inside a function, as follows:

var i:int = 10;

Place your cursor anywhere within the variable definition, and invoke Quick Assist. Then, select Convert Local Variable To Field. The class field is created as follows:

private var i:int;

The name of the new field is the same name as the local variable, provided there are no conflicts in the class scope. If the name exists, then the field name is incremented, and you can rename the variable or method in your file.

Convert Local Variable to Parameter

When you have a local variable inside a function, Quick Assist lets you convert the local variable into a parameter.

For example, if you have a variable inside a function, as follows:

public function method():void { var i:int = 10; }

Place your cursor anywhere within the variable definition, and invoke Quick Assist. Select Convert Local Variable To Parameter. The parameter is created as follows:

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

public function method(i:int):void {

i = 10;

}

After the parameter is generated, you can rename all references of the parameter using linked mode.

Convert Anonymous Function to Named Function

When you have an anonymous function, you can quickly convert it to a named function using Quick Assist.

For example, if you have an anonymous function, as follows:

public function method1():void; {

var foo:Function = function(x:int, y:int, z:int):void; {

trace(x, y, z);

}

Place your cursor within function(), and press Control+1. Then, select Convert Anonymous To Named Function. The named function is created as follows:

public function method1():void;

{

var foo:Function = fooFunction; } protected function fooFunction(x:int, y:int, z:int):void; {

trace(x, y, z); }

After the function is generated, you can rename all references of the function using linked mode.

Assign Parameter to New or Existing Variable

When you have a function containing a parameter, Quick Assist lets you assign the parameter to a new instance variable.

For example, if you have a function containing a parameter, arg, as follows:

class A{

function method(arg:String):void { }

}

Place your cursor within arg, and invoke Quick Assist. Then, select Assign Parameter To New Instance Variable. The statement is changed to:

class A {

private var arg:String; function method(arg:String):void { this.arg = arg; }

}

If you have instance variables already defined, you can assign the parameter to one of them.

For example, if you have a variable, myArg, defined as:

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

class A {

private var myArg:String; function method(arg:String):void { }

}

Place your cursor within arg, and invoke Quick Assist. Quick Assist detects the myArg variable, and shows the option Assign Parameter To Instance Variable 'myArg'. Selecting this option, changes the statement to:

class A {

private var myArg:String; function method(arg:String):void {

myArg = arg; }

}

After the variable is generated, you can rename all references of the variable using linked mode.

Create New Local Variable With Cast Type

Quick Assist lets you quickly create a cast type local variable within a conditional expression.

For example, if you have an if statement:

if(myObject is Button) { }

Or a while statement:

while(myObject is Button) { }

Place your cursor within the if or why statement, and invoke Quick Assist. Quick Assist shows you the option Create New Local Variable With Cast Type. Selecting this option generates the following conditional expression:

if(myObject is Button) {

var button:Button = myObject as Button;

}

After the local variable is generated, you can rename all references of the variable using linked mode.

Replace Conditional Statement With If-Else Statement

Quick Assist lets you replace a conditional statement with an if-else statement.

For example, if you have a conditional statement, as follows:

var foo:String = bool?"Yes":"No";

Place your cursor anywhere within the condition statement, bool?"Yes":"No", and invoke Quick Assist. Then, select Replace Conditional With 'If-Else'. The if-else statement is generated, as follows:

var foo:String;

if (bool)

{

foo = "Yes";

} else

{

foo = "No";

}

Add Else, Else-If, Finally, and Catch statements

If you have an If statement, you can use Quick Assist to add Else and Else-If statements.

For example, when you have an if statement:

var foo:Boolean = false; if(foo) { }

Place your cursor within if, and invoke Quick Assist. Quick Assist shows you options to add else and else-if statements. If you’ve defined an else statement already, then Quick Assist shows you an option to add an else-if statement.

Similarly, if you’ve defined a try statement, you can add finally and catch statements.

Generate Getter/Setter

Quick Assist lets you generate getters and setters (get and set accessor functions) for class variables.

For example, if you have code like the following:

private var result:ResultEvent;

Place your cursor in the variable, result, and invoke Quick Assist. Then, select the option to create the getter and setter for result. The Generate Getter/Setter dialog box appears. Using this dialog box, you can specify a new getter and setter function. For more information on generating getter and setters, see

“Generate get and set accessor functions”

on page 53.

Generate functions

Quick Assist lets you generate special functions such as labelFunction, iconFunction, and such.

For example, to create a labelFunction for the following code:

<mx:DataGrid labelFunction="lblfunc" dataTipFunction="tipFunc" />

Place your cursor within "lblfunc", and invoke Quick Assist. Then, select the option to create the labelFunction. Stub code for the function is generated as follows:

protected function lblfunc(item:Object, column:DataGridColumn):String

{ // TODO Auto-generated method stub }

Generate event handlers from MXML code

Quick Assist lets you generate event handlers with custom handler names within MXML code.

For example, to generate an event handler on clicking an <mx:Button> tag, enter the following code:

<mx:Button click="clickHandler" />

Then, place your cursor within "clickHandler", invoke Quick Assist, and select generate event handler. The event handler and stub code are generated as follows:

<mx:Button click="clickHandler(event)" />

protected function clickHandler(event:MouseEvent):void

{

// TODO Auto-generated method stub }

You can also generate an event handler for the following code, by pressing Control+1 anywhere within

"clickHandler(event)".

<mx:Button click="clickHandler(event)" />

To customize the predefined stub code that Flash Builder generates, see “Code templates” on page 38.

Quick Fix

The Quick Fix feature in Flash Builder identifies unresolved issues in code and prompts you with a list of options to fix your code. The Quick Fix feature is supported only for ActionScript files or ActionScript code in an MXML file.

For example, when you have code as follows:

import flash.display.Sprite;

public class QuickFix extends Sprite {

public function QuickFix()

{

var t:TestUnitClass

} }

Flash Builder identifies the undefined variable by an error indicator with a bulb next to the error icon . When you hover your pointer over the undefined variable, you see the following Quick Fix options:

To use the Quick Fix feature, do any of the following:

• Select Quick Fix/Assist from the context menu in the editor, and select the required option.

• Use the keyboard shortcut Control+1(Windows) or Command+1 (Mac OS), and select the required option.

Format, navigate, and organize code

The Flash Builder editors provide many shortcuts for navigating your code, including folding and unfolding code blocks, opening the source of code definitions, and browsing and opening types. Code navigation includes the ability to select a code element (a reference to a custom component in an MXML application file, for example) and go to the source of the code definition, wherever it is located in the project, workspace, or path.

Multiple line code blocks can be collapsed and expanded to help you navigate, view, and manage complex code documents. In Flash Builder, expanding and collapsing multiple-line code statements is referred to as code folding and

unfolding.

Code formatting, indenting, and commenting

As you write code, Flash Builder automatically indents lines of code to improve readability, adds distinguishing color to code elements, and provides many commands for quickly formatting your code as you enter it (adding a block comment, for example).

To change the default formatting, in the Preferences dialog box, select Flash Builder > MXML Code > Formatting. You can change the order and grouping of the attributes.

When you paste MXML or ActionScript code into the code editor, Flash Builder automatically indents the code according to your preferences. You can also specify indenting for a selected block of code.

To specify the indentation preferences, in the Preferences dialog, select Flash Builder > Editors. You can specify the indent type and size.

Set, fold, and unfold code blocks

1 In the editor, click the fold symbol (-) or the unfold symbol (+) in the editor’s left margin.

Folding a code block hides all but the first line of code.

Unfolding the code block to make it visible again. Hold the mouse over the unfold (+) symbol to show the entire code block in a tool tip.

2 By default, code folding is turned on in Flash Builder. To turn off code folding, open the Preferences dialog and

select Flash Builder

> Editors, and then deselect the Enable Code Folding option.

Apply syntax coloring preferences

You can easily adjust syntax coloring preferences.

❖ Open the Preferences dialog and select Flash Builder > Editors > Syntax Coloring.

For more information, see “Syntax coloring” on page 239.

Default font colors can also be configured on the Text Editors and Colors and Fonts Preferences pages (see Preferences > General > Appearance > Colors and Fonts. See also Preferences > General > Editors > Text Editors).

Indent code blocks

The editor automatically formats the lines of your code as you enter it, improving readability and streamlining code writing. You can also use the Tab key to manually indent individual lines of code.

When you copy and paste code blocks into Flash Builder, Flash Builder automatically indents the code according to your indentation preferences.

If you want to indent a block of code in a single action, you can use the Shift Right and Shift Left editor commands.

Shift a code block to the left or right

1 In the editor, select a block of code.

2 Select Source > Shift Right or Source > Shift Left.

3 Press Tab or Shift Tab to indent or unindent blocks of code.

Set indent preferences

1 Open the Preferences dialog and select Flash Builder > Indentation.

2 Select the indent type (Tabs or Spaces) and specify the IndentSize and Tab Size.

Add comments and comment blocks

You can add or remove comments using options in the Source menu or by using keyboard shortcuts. You can add the following types of comments:

• Source comment for ActionScript (//)

• Block comment for ActionScript (/* */)

• ASDoc comments for ActionScript (/** */)

• Block comment for MXML ()

• CDATA block for MXML (<![CDATA[ ]]>)

Comments in ActionScript code can be toggled on or off.

Adobe Community Professional, Paul Robertson, blogged about using block selection mode.

Toggle comments in ActionScript code
